Can You Remove and Reinstall Solar Panels?

by vemcoblogs -

When might you want to remove and reinstall your solar panels? The most common instances would be when you are fixing the roof or the solar power system, or conducting maintenance on the roof or other equipment located in the area.

Common Solar Panel Installation Problems - And How to Avoid Them

 

Fixing the Roof

Even some of the smallest roof repairs may require you to remove and reinstall part or all of your solar panels. This can make repairing the roof simpler, without risking damage to your panels. If you need to replace sections of the roof and require these to be removed prior, hiring a solar professional to do it would be a practical move.

Fixing a Solar Panel System

When repairing parts of your solar power system, removing the panels can provide additional space for a more thorough analysis of the whole system. Also, it is often safer to carry out repair work on the roof after removing the solar panels, in order to avoid compromising their safety.

Other Reasons

Other times that you might need to remove and reinstall solar panels could be when you need to repair anything in and around the rooftop. For example, fixing satellite dishes and electrical wires which are usually located on the roof may necessitate this, as may events like relocating your solar power system.

Should I Attempt to Remove and Reinstall the Solar Panels By Myself?

Do keep in mind that it can be quite risky to do so without the appropriate tools and expertise. Certain special equipment is required for the task and taking apart the panels without proper knowledge can nullify any warranties and contracts on the product. Also, removing and reinstalling solar panels entail a complex permission process that is best dealt with by a solar expert.

Time and Cost to Remove and Reinstall Solar Panels

The total time and cost of removing and reinstalling solar panels depend mainly on the solar expert you choose for the job, though they should be able to quote a base price to begin with. This can be over and above the actual costs of repairing the roof or solar power system; so be sure to factor that in. 

The repair work can take another day or more, depending on the extent of work that needs to be done. So, the entire project can take about three days to complete. Of course, major repairs may need more time.

Certain other factors may include the condition of the roof, the panels and the hardware, as well as the weather and site location itself.

What Is Solar O&M And Why Do You Need It?

by vemcoblogs -

In any industry, operations and maintenance (O&M) are a crucial part of keeping the system running properly and efficiently. The solar industry is no exception and solar operations and maintenance (O&M) services or programs are required in order to maintain a standard level of performance for a solar energy system.

Advantages of module level power electronics in O&M for commercial systems | Solar Power Portal

Regular servicing helps you to optimize the productivity you get from your solar power plants while reducing costs for maintenance and repair. Compared to most other power generating systems, solar power stations are simple to maintain. However, you need to make sure that you invest in high-quality O&M which is carried out professionally. This is one of the most important ways to make sure that your solar power plant stays in good condition, does not experience unnecessary breakdowns, and runs at peak performance levels.

There are three main aspects to solar O&M — preventative maintenance, corrective maintenance, and condition-based maintenance.

Preventative maintenance (PM)

Preventative maintenance, as the name suggests, includes regular inspection and servicing of your equipment in order to avoid the system from malfunctioning, which can cause unnecessary losses in production. This kind of maintenance takes place before your solar power system has witnessed any sort of breakdown, and the upfront costs associated with it are usually low to moderate.

Corrective maintenance (CM)

Corrective maintenance pertains to corrective action required to be taken after your equipment has already experienced a breakdown. Although this strategy may not appear to cost much on the surface, there is a higher risk of component failure and potentially higher costs on the backend. That can otherwise be avoided more easily with proactive, preventative and condition-based maintenance.

Condition-based maintenance (CBM)

Condition-based maintenance is when your solar power systems are monitored using real-time data. This strategy places a high priority on optimizing operations and maintaining peak performance levels, and can even be done by third-party providers and integrators. However, it comes at a higher cost than the other two strategies of maintenance, but these may actually pay off because your system runs as smoothly and efficiently as possible.

So, it is safe to say that no matter which strategy you employ, solar O&M is a crucial aspect of your solar power system to ensure that it continues to operate at optimal levels at all times. Timely maintenance significantly reduces the possibility of breakdown and production loss. O&M providers like VEMC can offer planned maintenance schedules to optimize equipment performance and minimise downtimes. Additionally, creating an elaborate breakdown impact analysis of solar plant sites is necessary in order to prepare a priority matrix for spare management and better maintenance.

What are Valves? What are their types and applications?

by vemcoblogs -

No matter which supply system you are talking about, one piece of equipment is absolutely indispensable — valves. Why are these so important for the proper functioning of your supply system and which valves suit your needs the best? In this blog, we touch upon all these fundamental questions about these ingeniously simple yet essential instruments.

Valves are simply instruments that control, regulate or direct the flow in a supply system. These are used in pipelines carrying liquids such as water, oil, and chemicals, or gases such as natural gas and cooking gas. The most basic function of valves is to completely start or stop the flow. However, they are also used to regulate the flow or pressure, throttle the flow rates, and improve safety by relieving pressure or vacuum in the piping system. Valves also prevent a backflow of the liquid or the gas. Let’s take a look at some of the main types of valves and their unique applications.

  1. Ball Valve: These have a quick-acting 90-degree handle to provide easy on-off control. These are faster and easier to operate as compared to other valves as they do not require a protracted winding action. These valves are mostly used in refineries, fertilizer plants, petrochemical processes and thermal power stations.
  2. Butterfly Valve: These have a characteristically compact design and are therefore best suited for cramped spaces. Their name comes from the wing-like action of the disc which operates at right angles to the flow. These find use in sewage plants, chemical processing and petrochemical plants.
  3. Spindle Valve: These valves have the simplest mechanism as they merely require twisting of the spindle wheel attached to the spindle rod. This moves the gate at right angle to the flow and stops it. These valves are mostly used in water supply.
  4. Foot Valve: A foot valve is typically installed at a pump or bottom of a pipe. These have an open end with a shield or screen over them to keep out debris. These can be found installed in ponds, lakes and pools on a pump. They let the liquid to flow in but prevent it from flowing back out.
  5. Sluice Valve: A sluice valve is a large valve with a rectangular or circular gate. On rotating the spindle, the gate slides across the opening. These valves find wide application in water works, effluent treatment, shipping, irrigation and thermal power plants.

What is a fire panel and how does it work?

by vemcoblogs -

Fire breakouts in a commercial facility like a factory could cause serious damage. Not only can it destroy valuable raw material and machinery, but worse, cause loss of lives on the factory floor. A flawless mechanism for early detection and response to a fire breakout is therefore necessary. Once you have installed a high-tech fire panel, you have every reason to put your worries to rest. In this blog, we take you through what a fire panel really is and how it works in the unfortunate event of a breakout.

A fire panel is an automatic fire detection and response mechanism. The panel doesn’t detect fire on its own but is capable of receiving signals from smoke detectors, a manual call point, or a pull switch. Once the signal is received, its response is activated. The most basic response is to raise a loud alarm to warn the workers about the fire so that they may quickly evacuate. However, depending on the type of fire panel, it can also activate the building’s water sprinkler system or even send a signal to the fire department.

In a conventional panel, the smoke detectors send a signal by changing the electric current as soon as they detect smoke. The altered current acts as a fire signal for the panel. Due to the installation of these panels in different wings or floors of the building, these are also called ‘zoned panels’.

A more advanced type of fire panel operates through IoT technology. It has a number of devices located throughout the building, each of which has its own MAC address and microprocessor to send signals to the panel. Rather than using altered current, these devices use the WAN or Wi-Fi network of the building to signal a breakout. As the fire panel detects the MAC address of the device, it can easily locate the fire break out anywhere in the building. As such, these modern fire detection systems are also known as ‘addressable panels’.

The kind of fire panel that you must install in your building depends on a number of factors. Some of the crucial ones are the type and size of the building, electrical fitting and internet connectivity, the number and spatial spread of the staff on the factory floor, and of course, the budget allotted for your fire security system. A generous budget can provide you with the comprehensive security of a fire panel that not only raises the alarm or signals the fire department, but can also lock or unlock doors, turn off the electricity and disable the elevators, therefore fully integrating all the security protocols in case of a breakout.

Using IoT and Analytics to Revolutionize Pump Monitoring

by vemcoblogs -

The Internet of Things (IoT) and Analytics are transforming every sector of the economy! There is absolutely no reason why pumping should remain untouched by these disruptive technologies. Any device that generates data about its performance parameters can be made a part of an IoT network. This ensures its optimum performance, highlights maintenance needs and predicts breakdowns for timely action. In this blog, we take you through the inner workings of how IoT and Analytics are revolutionizing your pump monitoring.

As your smart pumps function, they continuously generate a stream of data about variables such as flow, viscosity, vibration, power and temperature. The purpose of IoT and Analytics is to tap this continuous flow of data and ensure better vigilance and monitoring. Modern pumps require a seamless convergence of three key technologies:

  1. IoT: This includes the sensors and network infrastructure for connecting the smart pumps and conveying the data stream of the variables. Technologies like WiFi, LoRaWAN and NB-IoT are used to communicate the real-time data captured by the sensors. These networks are suited for large industrial establishments as they offer a wide range of up to 1 kilometre. The IoT setup also includes data management and retention tools offered by major cloud infrastructure companies. 
  2. Digital Twins: This refers to a virtual representation or simulation of the smart pump along with all its real-time variables. It is a model of the IoT pumps loaded with specific information such as brand, size and location. Data related to vibration, power, temperature and flow is clearly visible through the Digital Twin. You can also set limits on these parameters, which if breached, indicates the need for intervention. Digital Twin precludes the need for any physical monitoring of the pump as the model with accurate real-time data can be viewed anytime and from anywhere.
  3. Data Analytics and Machine Learning: These include the tools to keep track of the steady processes and detect anomalies for intervention. Tools like charts, graphs, time-series and trend analysis are used to gain an insight about the performance of the pump over a longer time-horizon. This information provides a multi-dimensional view of your pumps as it factors in the various parameters and their interaction with each other.

To make the best use of IoT and Analytics, an interactive user interface is a must. KirloSmart is a state-of-the-art software technology that allows users to analyse their pump metrics remotely through a web portal or mobile app. KirloSmart is capable of generating alerts for probable causes leading to breakdown or pump failure, thus keeping you up-to-date on the health of your smart pump. The greatest benefits of IoT and Analytics include scalable throughput and productivity, reduced energy consumption, controlled maintenance costs, reduced manual intervention and continuous improvement. This has made pumping convenient, reliable and sustainable. For more information on our products, feel free to contact us on +91 98199 07445.

Diesel Engine Control Panel

by vemcoblogs -

Control panels provide a simple user interface to operate, monitor, and control an otherwise complex piece of machinery. Their foremost and most basic feature is the switches to start or stop the machine. Visually these panels indicate the measurements of various parameters of the machine such as voltage, current, and frequency. In case the machine overheats, over speeds, or slows down due to a number of internal and external factors, control panels also facilitate an intervention. In this blog, we unpack the features, uses, and capabilities of a diesel engine control panel for you.

The most important function of diesel engine control panels is to control and protect the diesel engine. The control panel comprises a set of integrated components that monitor the diesel engine parameter readings to stay within the safe levels. The diesel engine control panel functions through the coordinated action of the following components:

  1. The Diesel Controller Unit 

Just like the CPU of a computer, the control module is the brain of your panel. It is a device that controllers the circuit of the panel using a microprocessor controller and paraments of a diesel engine based on changing conditions or shifts in parameters.

  1. The Terminal Rail

This is the junction of all the wires and connectors coming from the engine and the alternator. These wires are linked to the control panel to establish a two-way connection between the engine and the panel. Inputs on the control panel reach the engine and alternator while changing parameters in the engine and alternator are relayed to the panel.

  1. Battery Charger 

Inside the control panel, there are independent fully automatic microprocessor-controlled battery chargers rated at 10 Amps. The battery chargers operate in such a manner as to ensure that the engine batteries are fully charged within 24 hours. PCB mounted LEDs are provided for indication of AC Power On, and Battery Power On.

  1. Circuit Breaker

Just as in many other electrical and electronic devices, the role of the circuit breaker is to stop the flow of current in case of overload or short-circuit. This mechanism is very crucial to keep your diesel engine safe from a sudden spurt in electricity.

The diesel engine control panel is thus an effective device to monitor and control your generator. These days, the panels also include hi-tech LCD screens, displays showing running time, oil pressure and temperature sensors, remote start or stop capabilities, and an emergency shut-down lever. While most manufacturers include these as standard features, you may place an order to assemble a customized control panel based on your unique requirements.

How Solar Panels Produce Electricity

by vemcoblogs -

Solar energy is one of the most promising sources of electricity owing to a number of inherent factors. Unlike conventional sources of energy like fossil fuels, solar radiation is abundantly received in most regions of the world. Electricity generation by solar requires little to no inputs of raw material and perfectly fits the bill for clean energy. But what is the science behind tapping solar energy? How exactly do solar panels produce electricity and how efficient is solar energy really? In this blog, we simplify the working principles behind solar electricity and elucidate your understanding of this magnificent fuel for the future.

Solar panels are made up of a number of Photovoltaic (PV) cells (named so because they convert solar energy into electric energy). The PV cells are made up of semiconductor materials such as silicon that absorb solar radiation and release a number of electrons, which then travel freely in the cell. To create an electric field when sunlight hits the panel, a positively and a negatively charged semiconductor is sandwiched together. The electric field directs the flow of the loose electrons towards the conductors lining the cell, which then flow through the wires as Direct Current (DC). 

The DC then reaches the inverter that converts it into the most commonly used Alternating Current (AC). Finally, a wire carries the AC from the inverter to an electric panel which acts as a junction for distributing the current throughout the building.

One PV cell typically generates two watts of electricity. However, when a large number of PV cells are connected together on a solar array (PV panel), hundreds or even thousands of kilowatts of electricity can be generated. A PV panel is made up of solar cells arranged in the configuration of 32, 36, 48, 60, 72, or 96 cells. The larger the assembly, the greater will the electricity produced be! The standard panel size for commercial use is 77 x 39 inches, while that for residential purposes is 65 x 39 inches. 

The energy efficiency of most PV panels ranges from 15% to 20% at present. This is affected by varying solar radiation received at different geographical locations. Sunlight also varies according to the time of the day and seasons of the year. Besides, obstruction, shade and unclean panels can also reduce production significantly.

The principle behind solar energy is quite simple. However, there’s still ample scope for advancements in order to boost production capacity and enhance efficiency. This demands generous funding in the field to promote research and innovation. For more information on various types of solar services, feel free to contact us on +91 98199 07445.

VEMC at 73: Recollecting the Years Gone By

by vemcoblogs -

On 11th August this year, VEMC turns 73. A business spanning the better part of the last century speaks volumes about our experience, expertise and competence. On the occasion of our 73rd anniversary therefore, we decided to take you down the memory lane by recollecting the years gone by.

Vijay Engineering and Machinery Co. was founded in 1948 by Late Shri Sharad Kumar Shah along with Late Shri Rajaram Shinde, both entrepreneurs par excellence with a penchant for engineering and machinery. Their first office was a 100 square feet room at Commerce House in Ropewalk Street Bombay. During those days, erratic electricity even in urban and commercial areas, often compelled users to look for alternatives for running their equipment. The company saw this as an opportunity worth exploring and participated in an import auction of Petter Field Engines. The product, owing to its high quality, turned out to be a great success and gave VEMC a spectacular start.

During the 1950’s, VEMC made its way to various government projects and forged associations with many renowned companies. These included Kirloskar Brothers, WRT Talwalkar Pvt. Ltd., Bush Electricals and MICO Full Injection Equipment Company. The diverse nature of these projects vastly added to our product basket and also to the depth of our client profiles. Strong emphasis on ethics-based business practices and customer-centred approach soon became the defining features of our brand.

The 60’s was a time of expansion for the company. In this period, the government framed policies that laid emphasis on providing basic necessities of life, especially water, to all citizens of the country. The dry hinterland of western India was an important focus area and became VEMC’s market for Vertical Turbine Pumps. After this, VEMC group took a bold step and went beyond their comfort zone of the western region, and established the Rajendra Engineering Company in West Bengal, as the state distributor of Cooper Engines.

Radical changes in the style of doing business were seen in the decades between 1970 and 1990. The scope of work changed from supply of products to taking up turnkey projects, especially in the water pumping business. With its dynamic leadership at the helm, VEMC was up for the challenge and established Shailesh Engineering in Bangalore, a company that mostly handled turnkey projects for government’s water supply scheme and thermal power plants.

As the Indian economy opened up in 1991, new challenges came our way. Multinational companies began making in-roads into the Indian market giving VEMC and its partners a very stiff competition. However, the many years of trust and high-standards of service now bore fruit as the company remained unfazed in the wake of this altered situation. In fact, new avenues, such as building and construction began opening up to VEMC. In 1996, VEMC was awarded as the number one channel partner across India! In the period from 2003-08, the company grew at a rate of 20% CAGR, owing largely to its government projects.

Thus, after years of arduous efforts and strongly rooted business ethics, VEMC has been able to carve out a unique brand image for itself: one that emanates unfailing trust, relentless confidence and an inspiring vision for the future.

How Solar, Wind, and Hydropower can Outclass Coal Energy

by vemcoblogs -

For a very long time in modern human history, coal dominated the energy market as the cheapest, most easily available, and readily combustible source of energy. Coal energy was in fact the force behind the Industrial Revolution and continued to power factories, trains, and smelting furnaces, even into the twenty-first century.

However, today there is a huge concern to shift our energy demands from fossil fuels such as coal to renewable energy like solar, wind, and hydropower. This is due to the growing awareness about environmental issues and also the exhausting fossil reserves across the world. In the developed world, the transition is already evident, with shrinking demand for coal in the electricity sector. More and more power plants are switching over to solar and wind farms as the main source of energy to generate electricity. In the US, the Energy Information Administration (EIA) reported that the demand for coal in the electricity sector shrank from 28% in 2018 to 22% in 2019 (source).

As declining reserves of coal impact supply and leads to increased prices, renewable energy will be seen as a more cost-effective source of energy. This will draw the commercial sector further towards renewable energy as it will not just make them more compliant with their environmental legislation but also help them cut their energy bills and improve their margins.

India has set itself a target of producing 175 GW of renewable energy by 2022, out of which 100 GW will come from solar energy, 60 GW from wind, 10 GW from biomass, and 5 GW from hydropower (source). Increasing reliance on non-fossil energy is especially important for India to keep threats from climate change under check while its economy grows at a steady pace.

Critics take an interesting line of attack at renewable energy: The sun doesn’t always shine and the wind doesn’t always blow. This seems like a valid criticism but overlooks the stupendous growth of research and innovation in renewable energy (especially solar energy), backed by generous funding. This has greatly enhanced the storage systems so that the energy is used as and when needed. This has also placed renewable energy on the trajectory of increasing efficiency and declining equipment costs.

As fossils fade away into the background of the energy conundrum, renewable sources of energy like solar, wind, and hydropower will form the dominating portfolio for our energy needs of the future.

5 Steps to Achieve Maximum Air Compressor Efficiency

by vemcoblogs -

The key to optimal air compressor efficiency is to maintain the integrity of your entire pneumatic system. This includes the air compressor, fittings, air hose, and tools. An efficient pneumatic system will ensure that you’re getting the air you need when you need it. An inefficient one will cost you time and money. So, here are 5 steps that will make sure your pneumatic system keeps operating the way it was intended to.

  1. Use 3/8-inch Air Hose: Whenever possible, use a 3/8-inch air hose to ensure you get the maximum amount of pressure to the tool. While a 1/4-inch air hose is lighter to work with, its smaller diameter restricts airflow and causes a greater degree of frictional loss. As a thumb rule, opting for a larger diameter hose ensures the maximum amount of pressure to the tool.
  2. Use Shorter Lengths of Air Hose: The longer the distance air has to travel, the greater is the loss of pressure. For the maximum amount of pressure, use shorter lengths of air hose wherever possible. This, however, may not be possible in certain unavoidable situations, and in that case, using an auxiliary tank can come to your rescue.
  3. Use an Auxiliary Tank: An auxiliary tank acts as a reservoir of extra air and allows a user to maximize the distance between the compressor and the tool. It also helps minimize frictional loss.
  4. Lubricate your Pneumatic Tools Regularly: Using lubricants on movable parts can reduce friction and achieve greater levels of efficiency. It is important to consider the frequency of lubrication as well as the type of lubricant being used in the tools. For tools that are used daily, 4-5 drops at the start of each shift, is the norm. Using the wrong type of lubricant can damage the O-rings and other critical components.
  5. Check the System for Leaks: This can be done simply by allowing the compressor to build top pressure with the air hose and other components connected. Once the compressor has stopped pumping, watch the tank pressure gauge and listen carefully for any hissing noise. If the needle of the pressure gauge drops continuously, it indicates a leak. If on the other hand, it stays put and there is no hissing noise, the system is completely leak-free. Leaks in the system can cause excessive running of the compressor, leading to early wear and tear. A leak can be detected by spraying soap water on the hose and other components and looking for the formation of bubbles.

Different Types of Air Compressors

by vemcoblogs -

Compressed air is a great source of energy in wide-ranging industrial operations and is used for powering tools like impactors, drills, and other equipment. Air compressors, therefore, act as engines to create and supply this powerful driving force. Compressors are prone to falling into disrepair, especially due to impure, humid, or hot air, and therefore require regular maintenance, care, and protection to ensure optimum level performance.

Different types of air compressors are used in the industry, each with unique designs and operation specifics. So, you must understand the difference between all of these air compressors. Buying the right type of compressor from a reputable company ensures a longer lifespan and higher returns on your investment. In this blog, we shall take a look at the most common types of air compressors in use today.

Reciprocating Air Compressor

A Reciprocating Air Compressor, also known as a Piston Compressor uses one or more pistons to compress the air which enters it through a system of valves. The compressed air then flows into the holding tank. This is one of the most widely used types of industrial air compressors and finds application in areas like chemical processing, gas transmission, and hydrocarbon refining.

Screw Air Compressor

Screw Air Compressors make use of two closely meshing helical screws to compress air. Once the air enters into the chamber, the helical screws are turned to push it down into an extremely constricted space, which increases its pressure manifold. These compressors are mostly used in refrigerators and automated manufacturing systems. In the construction sector, these are used to provide compressed air to jackhammers, riveting tools, pneumatic pumps, sandblasting operations, and industrial paint systems.

Centrifugal Air Compressor

A centrifugal compressor makes use of a fast-rotating impeller and radial blades which create centrifugal force to suck the air in. These days, centrifugal compressors have high-speed electric motors to drive the impellers and create powerful centrifugal force. These compressors are used in gas turbines, automobile turbochargers and superchargers, oil refineries, natural gas processing, air-conditioning, and HVAC systems.

Oil-Free Scroll Compressor

Air compressors have a number of moving parts which create friction and wear and tear, leading to early degradation of the compressor. As such, oil lubrication is a must for air compressors. However, frequent oil lubrication can be burdensome and may not be suitable in operations where cleanliness is of utmost importance. Oil-free scroll compressors can come in handy in such situations. These use the rotary movement of scrolls to compress air into a very small space and pass it through the air outlet located at the centre of the scroll.

4 Tips on Increasing Solar Panel Efficiency

by vemcoblogs -

As the demand for sustainable energy grows, solar power stands out as the most favoured choice for the future. However, as solar systems require significant investment due to the high cost of semiconductors and allied components, it is important that maximum possible energy is generated from each square foot of a photovoltaic panel. Solar Operations and Maintenance (O&M) companies play a huge role in ensuring the highest efficiency of the solar power systems but some simple tips based on a common understanding of solar energy can go a long way in enhancing your output.

Well, the science behind solar energy is very simple — the higher the exposure of solar cells to sunlight, the greater will the output be. It is around this fundamental principle that most of these efficiency-enhancing tips revolve:

  1. Avoid shade: Due to the installation of intricate groupings of solar cells in a panel, even if a small part of the panel is covered by shade, the whole module will have less energy conversion. Shade is therefore a major inhibitor of solar energy and must be minimised as much as possible. This requires careful placement of the solar panels, away from a permanent high-rising object like a chimney or a vent. Tall trees around the facility must be well-trimmed to ensure their shadow doesn’t fall on the panels at any time of the day.
  2. Careful orientation: Solar panels must be oriented in the direction where they receive maximum sunlight throughout the day. This completely depends on the geographical location of the installation. India being a country in the northern hemisphere, the solar panels are always made to face the south to receive maximum sunlight. In the US, both south and west are the favoured directions and have been known to produce the maximum output.
  3. Proper upkeep: Solar panels can get covered in dust, dirt and bird droppings in a very short span of time. As they are mostly installed on rooftops, it might get a little difficult to clean the panels regularly. This could reduce the efficiency of the panels as some or whole of their surface area is screened from the sunlight. Providing convenient access to the panels and cleaning them regularly is therefore important.
  4. Weather: Hotter days ironically generate lesser energy due to increase in current and drop in voltage. While controlling the weather is beyond our ability, we can surely be mindful about buying panels with the lowest temperature coefficient, which refers to the amount by which the output of a panel reduces after temperature rises beyond 25⁰C.

Challenges in Operations and Maintenance of a Solar Plant

by vemcoblogs -

From keeping plants running in optimum condition, manpower optimization, budget, and spare management for the smooth operation of a plant, to maintaining safety protocols, there are several challenges in solar operations and maintenance (O&M). In this blog, we will take a look at the multi-dimensional nature of these challenges.

The unexpected challenges of solar power | World Economic Forum

Preventive Maintenance

Preventive maintenance is a continuous process that aims at preventing sudden breakdowns and various costs accruing from it. It is carried out systematically, by following Standard Operating Procedures (SOP’s) and Standard Checklists, which help ensure consistency and quality of work. 

Condition Monitoring 

A significant change in the condition of the equipment is often clearly visible and can indicate the increased likelihood of breakdown at some point. It is important to repair or replace the equipment in time, especially if it is crucial to the working of the plant.

Corrective Maintenance

Despite all the efforts, some faults might arise in the system, which may need immediate corrective measures. This could include replacement of the faulty equipment or intervention by technical staff to restore its functioning.

O&M Budget

Cost control is an essential part of any solar O&M strategy and must be viewed in a comprehensive way. It is essential to reconcile the interests of the stakeholders with the objectives of controlling costs associated with system maintenance, quality checks, and testing procedures.

Documentation

A complete record of all activities taking place at a solar plant site must be well-documented and available for reference to all stakeholders, to ensure identification and removal of loopholes and procedural inconsistencies.

Spare Management

A formal inventory management system must be in place to keep a record of the type and quantity of spare parts available. These must be stored in an organised way to ensure ease of access during a breakdown.

Skills Training and Development

Working on-site can be full of challenges for which the personnel must be trained in order to increase their capacity across a range of tasks and reduce on-site accidents. This includes the development of technical skills and knowledge of standardized procedures and checklists.   

Plant Performance

To keep the plant at peak performance levels, it is essential to take a holistic view across human, technical and environmental dimensions of the plant. This includes functions like periodic module cleaning, vegetation control, spares management, manpower management, quality control, and Supervisory Control and Data Acquisition (SCADA) monitoring.

Safety

Safety measures while being on-site are essential for both personnel as well as the equipment. Proper safety procedures must be followed and protective gear must be used to prevent any kind of hazard.

Maintenance for Air Compressor Systems

by vemcoblogs -

Maintaining air compressor systems is simple but very important! It requires combating heat, moisture, and loss of air pressure, to ensure peak levels of performance and also prevent early degradation of the compressor system. Heat causes motors, bearings, and oil to break down while moisture can affect the internal parts of the compressor by corrosion and microbial growth. Loss of air pressure makes the compressor do more work for the same volume of compressed air. So, in order to ensure the smooth running of operations, avoid interruptions and unexpected downtime, it is crucial to maintain the compressor at regular intervals. In this blog, we take a look at the measures that need to be taken.

Maintain the Coolers and Filters

  • Heat being the number one enemy of compressors, it is extremely important to keep the intercoolers and aftercoolers clean. These cool the air between the stages and after compressing the air respectively. 
  • It must also be ensured that the oil cooler is working properly. This is mainly responsible to prevent the degradation of oil and reduction in its life with rising in temperatures. Regular testing of the compressor oil is an important maintenance practice to predict the breakdown of oil before it becomes problematic.
  • The air inlet must be kept safe from dust, dirt, and contaminants. Regular replacement of air filters is very effective in keeping the air compressor clean on the inside.

Remove Compressed Air Condensate

  • As air is compressed, it ejects excess water that it cannot hold. In the humid spring season, this water could gush into your distribution system while in winters it can freeze inside the system and damage the piping. Clogged traps and stuck open valves must be regularly checked to ensure the removal of condensate from the system.
  • It’s important to check the drain valve regularly to ensure only clean and dry air is coming out. Any presence of moisture indicates retention of the condensate in the compressor and must be treated immediately to prevent corrosion and fungal and bacterial growth inside the system.

Avoid Compressed Air Pressure Loss

  • It is essential that the air pressure is maintained at the level suitable for your operations. Any drop in the pressure means the system is not operating at peak efficiency vis-à-vis the consumption of energy.
  • Change the inline filters and point of use filters as soon as they reach saturation. It is recommended that these elements are changed when the indicator reaches 6-8 PSI. Besides the filters must be inspected twice a year to ensure that they haven’t been compromised.

O&M Issues in PV Solar Energy

by vemcoblogs -
Solar PV Operations and Maintenance

Solar power systems have a life-span of 20-25 years which makes their Operations and Maintenance (O&M) very important. This is to maximise energy production and minimise maintenance costs over the lifetime of the system. Maintenance is a continuous process which not only reduces the risks and costs associated with sudden breakdowns, but also keeps the system at prime efficiency levels. Fortunately, solar systems have lower maintenance and servicing requirements as compared to other energy generating technologies. In this blog, we’ll take you through some of the common O&M issues of photovoltaic (PV) solar systems and the approach to deal with them.

Natural Degradation

All solar cells degrade naturally, regardless of the environment they are installed in. However, the rate of degradation depends on the material of the PV panels. For instance, monocrystalline silicon panels have the lowest rate of degradation while copper indium gallium diselenide (CIGS) panels have one of the highest. Since the material directly affects the cost of the panels, choosing the type of panels is essentially a planning, budgeting and investment decision.

Lightning Protection

Lightning strikes can damage the solar power system by causing a power surge within the array. It is important to have a grounding system in place to redirect the energy from the lightning, away from the panels and into the ground. While the mounting system of the panels itself plays the role of grounding it, the material of the mounting system must be chosen carefully. This also depends on the type of foundation of the system. Besides having a robust grounding system in place, it is advisable to install surge protection equipment for backup safety.

Failure of Components

Cracking of panels and their visual discolouration can affect the efficiency of the panels. Both of these are irreversible damages. High temperatures can damage the solar panels by producing hotspots on them. Inverter downtime is another common issue with PV solar systems and their scheduled maintenance is a critical part of a solar O&M strategy. For static solar panels, ideal panel orientation is necessary to get the highest output. In case of tracking systems, it is important to regularly check the moving parts like gearboxes, motors, and actuators.

Weather Conditions

The environment impacts the durability of PV systems and adequate measures must be taken to offset its effect. For instance, regular cleaning and wiping may be required in windy or arid areas while sloping solar panels can avoid an accumulation of snow in cold regions. In the case of hailstorms, protective covers could be useful to prevent damage to the panels.

That said, it’s absolutely necessary to have an O&M plan in place for your solar plant to alleviate long-term costs.
