String Inverters VS Micro Inverters: 6 Key Comparisons

by vemcoblogs -
solar power installation

Solar energy is becoming an increasingly popular way to generate electricity for both homes and businesses. As of 2023, 17% of India’s installed power capacity comprised of solar energy. One of the key components of a solar energy system is the inverter, which converts Direct Current (DC) power from the solar panels into Alternating Current (AC) power that can be used in your home or office. There are two main types of inverters: string inverters and micro inverters.

VEMC is a leading solar power installation company, and in this blog, we discuss the key differences between string inverters and micro inverters. 

String Inverters vs. Micro Inverters: The Basics

Both string and micro inverters perform the same function – converting DC to AC. However, the main difference lies in where and when they do so.

With a string inverter, all the solar panels are wired together by a single string, which is connected to an inverter installed next to the premises’ utility meter. Micro inverters, on the other hand, are mounted directly on each solar panel, hence converting energy at its source.

6 Key Differences between String and Micro Inverters 

Even though their functions are the same, choosing between string and micro inverters can impact cost, efficiency and monitoring ability. Here are the six differences between the two:

  • System Efficiency

While offering high-efficiency rates, shading on even a single panel can negatively impact string inverters. This is because the entire string operates at the lowest-performing panel’s output.

On the other hand, micro inverters allow for independent optimisation. This means shading on one panel minimally affects the overall system’s output. Micro inverters generally have slightly lower efficiency per unit, but the overall system efficiency can be higher due to better energy capture.

  • Cost Implications

String inverters are typically less expensive upfront due to the lower number of units required. Micro inverters, with more individual components, can have higher maintenance costs over time. However, the modular design makes troubleshooting and repairs easier.

Micro inverters can have a lower long-term cost due to their higher efficiency and potential for reduced energy loss.

  • Installation Flexibility

String inverters are easier to install because they have fewer components. Micro inverter installations are more complex, as each panel has to be connected to its inverter. 

However, micro inverters offer more system design and maintenance flexibility and can be ideal for complex roof layouts.

  • Performance in Shading Conditions

Shaders can significantly impact string inverter performance, as the entire string’s operation depends on the output of the lowest-performing panel. 

This is much more optimised for micro inverters, which function independently. While shading doesn’t drastically affect their performance, micro inverters also get the most energy out of systems with unique specifications.

  • Monitoring and Maintenance

String inverters provide system-level monitoring, offering less granular data on individual panel performance.

Micro inverters offer panel-level monitoring, providing detailed information on each panel’s output and performance. This makes troubleshooting and maintenance easier.

  • Lifespan and Reliability

String inverters are considered more reliable due to fewer components and a simpler design.

While individual micro inverters may have a shorter lifespan, the modular design allows for easy replacement of faulty units without affecting the entire system. They are ideal when:

  • Some panels are shaded
  • Panels are mounted facing different directions
  • There’s a plan to add more panels. 

Choosing the Right Inverter 

When working on solar power installation, the right inverter makes all the difference. To choose between string inverters and micro inverters, consider the following things:

  1. Size of your solar panel system
  2. Sun exposure to the system and roof layout
  3. Energy goals of your business
  4. Cost considerations

The Role of Solar Power in Reducing Energy Costs for Cold Storage Facilities

by vemcoblogs -
Solar installation

Cold storage facilities play a crucial role in the agricultural sector of India in the preservation of perishable items such as meat, dairy, and vegetables. However, maintaining these facilities is not easy. To maintain low temperatures, they need constant energy, which uses a lot of power. Because of this, cold storage facilities bear a heavy financial burden from electricity expenses. Hence, owners of cold storage facilities are looking for strategies to reduce expenses without compromising effectiveness due to increasing electricity rates. Solar installation offers a practical solution to meet energy demands and reduce costs.

In this blog, we will explore how solar services can revolutionise energy efficiency and reduce costs for cold storage facilities.

High Energy Demands of Cold Storage

Cold storage facilities are vital in India, where temperatures typically soar. To keep temperatures low, cold storage facilities need to use energy continuously. They operate nonstop to guarantee the products that are stored stay fresh. In fact, a sizable amount of operating costs in the cold storage sector are related to energy. This is particularly true in semi-urban and rural locations where power outages might occur, increasing expenses related to the need for backup generators.

Solar Power Integration in India

The integration of solar electricity into cold storage facilities has the potential to considerably reduce energy expenses. By installing solar panels, these facilities can generate their own electricity and become less reliant on the grid. When solar energy is harnessed during the day, it can be used to power the facility or to charge batteries for usage at night or on overcast days. Many parts of India see adequate sunlight for most of the year. For cold storage facilities, particularly those situated in regions with unstable grid supply, this makes solar power an excellent option. Facilities that install solar panels can benefit from solar battery storage, which allows operations to continue uninterrupted even in the event of a power outage.

Cost Savings through Solar Power

The potential for significant cost reductions is one of the main benefits of solar energy. Energy costs for cold storage facilities can be decreased by adopting solar solutions.

This is due to the reduced reliance on traditional grid power. Additionally, solar power can help offset peak demand charges, which occur when electricity usage spikes during high-demand periods. Cold storage facilities often face peak demand charges, especially during hot summers when cooling systems are working overtime. Solar installation allows facilities to generate consistent energy, reducing these charges and overall energy expenses.

Reliable and Consistent Energy 

In order to prevent perishable goods from spoiling, cold storage facilities need to have consistent temperature levels. Any disruption in the power supply can lead to massive losses. Solar power solutions guarantee that cold storage units continue to function even during blackouts when paired with battery storage. This is especially helpful in areas where electricity supply is erratic. Solar energy provides a dependable and renewable power source that keeps operations running smoothly without interruptions.

Environmental Benefits

In addition to cost savings and reliability, solar power offers significant environmental benefits. Solar energy is a clean, renewable source of power that doesn’t emit harmful greenhouse gases. For cold storage facilities, this means a smaller carbon footprint.

Cold storage is essential in preserving food and reducing wastage, but it also consumes a lot of energy, which can lead to high carbon emissions.  By adopting solar panel installation, cold storage operators in India can reduce their carbon emissions and contribute to the country’s sustainability goals. Solar power helps lower overall energy consumption and promotes greener operations.

  2. Inlet pipe: The water enters into the turbine through the inlet pipe. It ensures that the turbine receives a steady flow of water to keep the mechanism going.
  3. Nozzle: It regulates the flow of water to the runner and ensures optimum efficiency by directing the maximum amount of water to the runner.
  4. Turbine housing: The turbine is protected and enclosed by it. It is specifically designed to resist the force of flowing water.
  5. Shaft: This connects the runner to the generator, and thus transmits the mechanical energy of the runner.
  6. Generator: The mechanical energy transmitted by the shaft is converted into electrical energy by the generator. It consists of coils that rotate in a magnetic field and produce electricity.
  7. Governor: The role of a governor is to control the turbine speed and regulate the output of electricity.
  8. Outlet pipe: This discharges the water that has been used to generate electricity back into the stream or river while ensuring minimum environmental impact.
  9. Support structure: This includes mounting points and other associated structures that ensure the stability of the PICO system.

Suitable applications of PICO

As mentioned already, PICO generates up to 10 kW of electricity. This makes it most suitable for meeting small-scale demands or filling in for short-term disruptions or outages. However, the most outstanding feature of PICO is its compact size and portability. This makes it highly suitable for off-grid locations deep into the interiors with minimum connectivity such as remote villages and farms. PICO can therefore be a game-changer when it comes to improving the socio-economic standards of remote rural and agrarian communities, especially in the context of a developing country like India.

Advanced monitoring and diagnostics enable you to do exactly that, for zeroing in on issues and taking timely corrective action. VEMC is a leading solar EPC company based in Mumbai, and in this blog, we tell you all you need to know about performance analysis of your solar power system.

Benefits of advanced monitoring systems

  1. Identify performance issues early: Advanced monitoring and diagnostics technology acts as an early warning system for any performance-related issues which could lead to lower productivity and efficiency.
  2. Optimise system operation: The data collected by advanced mentoring and diagnostics system enables users to zero in on any system issues and take corrective course to optimise system operation.
  3. Maximise energy production: With advanced monitoring systems, users receive a stream of continuous and uninterrupted data which helps keep track of the energy produced by the panels. As soon as deviation is noticed in the production, it could point towards issues such as accumulation of dust, shading of the panels or bird droppings which act as barriers to the sunlight and reduce the energy produced. With timely action, energy production can be maximised. 

Types of data collected by monitoring systems

Monitoring systems keep a track of a wide range of relevant parameters which are critical indicators of your solar power systems’ performance, efficiency and productivity.

  1. Power output: This is one of the most significant parameters that users must track throughout the lifespan of their solar power project. A steady power output at peak levels indicates a healthy solar power system while deviations may signify its decline.

Solar Panel Cleaning and Maintenance: Methods and Scheduling

If you own a solar power system, you would realise that it is all about exposing the maximum surface of the panels to the sun for maximum possible time. What can really affect its performance and efficiency is barriers like dust and debris. This makes it extremely important to clean and maintain the panels regularly. We at VEMC are the leading solar panel consultants and installers based in Mumbai, and in this blog we talk about cleaning and maintaining your solar panels.

Factors affecting cleaning frequency

While it is necessary to clean your solar panels regularly, it cannot be feasible in terms of cost and labour to do so too frequently. Here are some decisive factors that determine how frequently you must clean your panels:

  1. Environmental conditions: The larger environmental context you are located in is the foremost factor to determine your cleaning frequency. For instance, you may need to clean the panels more often if you’re located in the middle of a busy urban centre or near a factory, as compared to a bucolic rural setting.
  • Dust accumulation: How much dust accumulates on your panels in a given setting will also determine the cleaning frequency. Dust could be raised by heavy traffic or industrial processes like mining or stone crushing.
  • Bird droppings: Another widely noticed barrier to sunlight shining on your panels is bird droppings. If your facility has a lot of trees nearby, it is quite likely that birds would fly over your panels and pound them with their droppings. This will make regular cleaning necessary.

Safe and effective cleaning methods

Cleaning your solar panels is quite simple and straightforward but for the sake of longevity, you must keep a few guidelines in mind.

  1. Use water and mild detergent: Use de-ionised, rain or tap water to clean your panels. Make sure the water is clean to prevent any mud or contaminants from remaining behind on the panels. Do not use any abrasive, acidic or alkalic cleaners on your panels. A regular mild detergent should do.
  2. Specialised cleaning brushes: These days, a lot of sellers are offering brushes made specifically for solar panels. These are often motorised and can clean in both linear and circular motion. Most importantly, they clean without leaving any marks or scratches on the surface.
  • Robotic cleaners: These are automated systems used to clean solar panel surfaces. These operate by using a combination of mechanical and smart technologies to clean efficiently. These are especially useful when your solar panels are out of reach or located too precariously for manual cleaning.

Recommended cleaning schedules

Solar panels must typically be cleaned twice a year. However, regular inspections are necessary to take more precise decisions and get maximum efficiency. Besides, the above-mentioned factors will also play a key role in scheduling your cleaning.

To get the most out of your solar power systems, cleaning and maintaining them is essential. We at VEMC offer comprehensive solar EPC contracts to our clients which cover everything your solar power system needs post purchase.

8 Common Mistakes to Avoid when Installing Solar Projects

by vemcoblogs -

Solar energy is fast becoming one of the most preferred alternative sources of energy. This is especially true of a tropical country like India which receives plentiful sunlight in most parts throughout the year. However, we are still in the early days of our solar journey and a lot of customers tend to make installation mistakes which can later prove costly. VEMC is a leading solar energy company based in Mumbai, and in this blog we tell you about the 8 common mistakes that you must avoid when installing your rooftop solar panels.

1. Understanding energy needs

The capacity of rooftop solar panel must be determined by the energy needs of your home or facility. However, consumers often make the mistake of considering only their current needs. Since solar power system is a long-term investment, you must plan ahead and also build capacity as per your projected needs in the future.

2. System sizing

To meet the energy demands of your facility, it is necessary that your solar power system is suitably sized. You must avoid both under as well as over-sizing of your solar power system. The former can lead to shortages of energy while the latter causes wastage.

3. Placement

Make sure your panels are properly positioned to face the sun maximum possible time for optimum productivity. This is where the skill, expertise and experience of your installer comes into play.

4. Financing your solar project

With a number of government incentives and financing options available, you do not need to finance your solar project all by yourself. All you need is some market research to choose the most cost effective financing option.

5. Obtaining permits

You must obtain a permit from your local power distribution company (DISCOM) before installing a solar power system. Additionally, look for other local body regulations which are mandatory in your locality, town or city before installing the panels.

6. Factoring in maintenance costs

Your solar power system doesn’t just have initial investment costs but also long-term or lifetime costs which customers often overlook when deciding to invest in one. Make sure you speak to an expert and factor in the maintenance costs of your solar power system before making the investment.

7. Avoid scams

With a lot of excitement about solar power systems in the air, customers may be tempted to invest in them by unscrupulous sellers claiming that these systems are money-minting machines. While on-grid solar panels do help reduce your bills through net metering significantly, they are not likely to make you rich overnight.

Sizing your solar system: finding the perfect balance for your energy needs

by vemcoblogs -

Having a solar power system is a smart way to meet your electricity needs at home and business. However, to make sure that you are able to fulfil your needs without wasting any energy, sizing your solar system is necessary. This allows you to avoid over or underinvesting in your solar system and getting just the perfect one suited for your needs. VEMC is the leading solar panel installation company in Mumbai and in this blog, we tell you how to perfectly size your solar system.

Factors to consider in sizing

  1. Consumption: 

Higher the levels of usage or consumption, more will be the size of the solar power system required. This means a bigger solar power system will be needed in a business or industrial setting as compared to a domestic one.

  1. Location: 

Where you live also impacts the sizing of your solar power system. If you live in a tropical region that gets plenty of sun all year round, even lesser solar panels will produce good amount of energy. However, in temperate regions, you my require bigger solar systems to make up for the low sunlight during the winter season.

  1. Climate: 

Although climate is largely a function of geographical location, some places neverthess are too cloudy or rainy due to other factors like altitude, monsoons etc. If you experience too much of overcast weather during the day, this will also necessitate installing a bigger solar power system.

  1. Efficiency: 

Highly efficient monocrystalline solar panels produce plenty of energy over a limited surface area. This also plays a role in determining the size of your solar system.

A step-by-step guide on sizing

  1. Calculate your usage: 

For starters, you must be aware of your annual energy usage. You can find this from your electricity bill which may also exhibit the peaks and valleys of energy consumption. Find out the average usage of electricity per day.

  1. Find out your peak sun hours: 

The peak sun hours vary according to your location and climate. To make the most of your solar power, find out your peak sun hours using a sun hours chart.

  1. Calculate the size of your solar power system: 

To find out the size of a solar power system that would be most suited for your needs, divide your daily energy requirement (in kWh) by your peak sun hours. This will give you a kW output. Divide this by your solar panel’s efficiency and you’ll get an estimate of the number of panels you’ll need.

Alternatively, if you know the “efficiency factor” of the solar panels (lets say 0.2), here’s the formula to find out the size of your solar power system:

(Daily kWh / Average sun hours) x 0.2 = Size of solar system

Proper sizing of your solar power sytems is very important to ensure optimal performance and cost effectiveness.

The efficiency of a solar plant is the output it generates relative to the space it occupies. Usually, solar power plants have an efficiency of 17 to 23%. But this can be stretched if you’re mindful of the workings of your panel. VEMC is the leading solar power company based in Mumbai.

7 critical factors that impact the efficiency of your solar plant

1. Solar panel quality

For starters, the quality of your solar panel and the kind of material used in your solar panels has a significant impact on its efficiency. Monocrystalline panels, for instance, have the highest efficiency of about 23%. These panels are also useful in case of limited space on the roof. On the other hand, thin-film solar panels offer the least efficiency.

2. Orientation of your solar panels

Ideally, the roof on which a solar panel is mounted should be south-facing and the slant should be between 30 and 40 degrees. This exposes the solar panels to the sun maximally. However, this may not always be possible and the installer must find the best possible placement of the system on your roof.

3. Shading

Shade from nearby trees or buildings blocks sunlight and reduces the efficiency of your solar panel by upto half. Make sure the system is installed at a location where there is no or minimum possible shade. In case of tall trees, the branches can be pruned and cut to prevent them from obstructing the sunlight.

4. Dust, dirt, and contaminants

In places where it doesn’t rain frequently, make sure you clean the dust and dirt regularly. Contaminants can block the sunlight from falling on your solar panel and affect its efficiency. Likewise, in winters, snow accumulated on the solar panel will also obstruct the sunlight. Regular maintenance and cleaning of the panels is necessary to ensure highest levels of efficiency.

5. Efficiency of the accessories

Accessories like inverters, wires and cables also affect the efficiency of the system. For example, connector wires that offer too much resistance to the current will impact the output. Make sure you always use genuine and high-quality accessories like inverters. 

6. Weather and climate

Solar panels function optimally within a certain temperature range. Extreme weather conditions can impact their efficiency and reduce the output. While snow and blizzard physically cover the solar panels, extreme heat can damage them and reduce the output. But as long as it doesn’t cover the panels, snow can improve the overall efficiency due to its high irradiance.

7. Maintenance and monitoring

Lastly, any solar system needs high maintenance and monitoring. You must regularly inspect the connector wires for any breakages. Make sure the site is free of rodents which may damage the wiring. Monitor the flow of current regularly and call your solar panel consultants and installers in case of significant fluctuations.

Industries across the economy are increasingly looking for energy alternatives. This is because of rising energy costs and increasing environmental concerns. Solar energy has emerged as one of the favorite sources of energy on many accounts. Solar energy is safe, inexpensive, abundant, and low-cost. Between 2023 and 2028, solar energy is expected to grow at a CAGR of 3.71%. VEMC is the solar epc based in Mumbai.

We take you through the financial benefits of solar plants for industries

Lower cost of energy

Being completely dependent on the electricity grid may subject businesses to electricity cost fluctuations and sudden spikes. In such situations, solar plants can provide a price buffer to businesses, thus keeping their operational costs under check. Having a solar plant makes a business self-sufficient and reduces its dependence on the commercial power grid. Even partial self-sufficiency can slash bills significantly.

Excellent ROI

Solar power plants are an excellent investment. On average, the entire investment is recovered within five years. Solar panels have a considerably long life span of 25-30 years. But most importantly, investing in solar power systems means benefitting from fixed utility rates for decades.

Lower overhead costs

Overheads such as supplies, utilities, and operational materials add up to a huge amount. With solar energy, businesses can significantly reduce these costs and improve their bottom line. 

Government and tax incentives

As solar energy has gained traction across the world, governments are promoting their installation through various financial incentives, subsidies, and tax benefits. Businesses in India can benefit from schemes wherein the government contributes some amount to install the plant. Besides, they can also claim accelerated depreciation on solar power systems which can reduce their tax liability significantly. 

Net metering

With an on-grid solar system in place, in case a business is generating more energy than it is consuming, it can actually export it to the grid. The amount exported will then be offset against the electricity consumed, thus reducing the electricity bill from the grid significantly.

Sustainability

Energy costs can skyrocket in the coming days as environment-related taxes are levied. With concepts such as Carbon Tax and Polluter Pays Principle over the horizon, sustainable operations have to be ensured. Only those businesses that are sustainable will be able to escape the scourge of such taxes due to lesser pollution or carbon emissions. Thus being a sustainable business can translate to significant financial benefits.

Improved reputation

Installing solar power systems can improve the reputation of a business, especially among the environment-sensitive public. Although indirectly, this could significantly boost the company’s image and entail greater revenue.

7 Critical Components of a Solar Plant

by vemcoblogs -

If you are a solar installation owner, you must be aware of all of its individual components and how they operate. This doesn’t just help in the day-to-day operation and maintenance of the solar plant, but also zero in on the troublesome parts in case of breakdowns. We at VEMC are one of the leading solar EPC based in Mumbai, and in this blog, 

Explore the main components of your solar plant

7 parts of a solar plant

  1. Solar panels
  2. Inverter
  3. Model mounting structure (MMS)
  4. Optimizers
  5. Cables
  6. Energy monitoring
  7. Battery storage

Solar panels

Also known as solar modules, these generate electricity when the sun shines over them. Choosing the right type and number of panels is necessary to meet your requirements optimally. Solar panels must be cleaned and inspected regularly to ensure optimum performance and productivity.

Inverter

The solar panels produce Direct Current (DC) while your appliances run on Alternating Current (AC).  It is the inverter that turns DC into AC to make the electric output usable. The inverter also keeps a check on the voltage flowing from the panels to your home or back to the grid.

Model mounting structure (MMS)

MMS is the most important part of your solar power infrastructure. A number of mounting structures are used depending on the type of surface you are installing the panels on. For instance, for low-slope roofs, ballasted MMS is used which uses a weighted tray to hold the panels in place. On the other hand, a ground-based solar installation uses an engineered MMS anchored in the ground.

Optimizers

As the name suggests, optimizers ensure the production of maximum power by the panels even if the surface has dirt, dust or shade. Optimizers are installed at the back of each solar panel. These also track the performance of the panels, thus assisting in troubleshooting. As soon as the system turns off, optimizers also automatically shut off power as a safety measure.

Cables

Your solar panel installation requires a robust network of cables to convey the current from the panels. These cables also interconnect the various components of the solar power system. Three main types of cables used in solar installations depending on their use are PV wires (mostly used for interconnection wiring), USE 2 wires (used in grounded solar panels), and THHN (used in wiring the buildings).

Energy monitoring

Energy monitoring is an important component of keeping track of your energy production versus consumption. The data on production and consumption monitoring helps keep tabs on the health, efficiency, and productivity of your solar power system.

Battery storage

Although not an essential component of your solar system, battery storage acts as a buffer. In times of electricity shortage or breakdown, battery storage works as a useful reservoir of energy. Batteries get conveniently and automatically recharged when the sun is shining on the panels.
Having comprehensive knowledge and understanding of your solar panel systems is important to keep track of how it is performing.

Solar panel installation can seem like a daunting investment. The upfront costs can in fact be the most significant deterrent against taking the solar option. However, with the right guidance, you can save plenty of money while installing your solar panel. VEMC is the leading solar energy company based out of Mumbai.

In this blog, we explain how you can save big on your solar panel installation

1. Government incentives

Governments across the world are trying to promote solar energy to shift their country’s reliance on conventional fossil fuels. By providing incentives to homeowners, they make the investment in solar energy an attractive prospect. India’s Rooftop Solar Programme by the Ministry of New and Renewable Energy is one initiative to exhort residents to invest in a solar rooftop system. To put things into perspective, solar energy systems of up to 3 kW are eligible for a subsidy of up to Rs. 14588/kW.

2. Financing options

Solar financing is another feasible option for homeowners who do not want to spend a huge sum on the installation upfront. This allows them to spread out the cost of the panel over a larger horizon. A number of private and public sector banks in India are offering solar loans at affordable interest rates of around 8%.

3. Select the right solar system

Make sure you’re selecting just the right size and type of solar panel system for your rooftop. For residential homes, 3-5 kW solar panels should be enough. Also, make sure you’re choosing a good quality solar panel system that helps you save energy in the long run. Monocrystalline solar panels typically offer better efficiency.

4. DIY installation

To save on your installation labor, you could perform a DIY installation. These days, a lot of resources like guides and tutorials are available online, which homeowners can use to install their panels. However, in the case of complicated rooftop design, unsafe mounting areas, or lack of the right tools, it is always better to rely on experts. 

5. Proper maintenance

Regular and timely maintenance is important when it comes to extending your savings. When solar panels are regularly inspected and maintained, the costs of sudden breakdown go down. Dust, ash, or other particulate matter can bar the sunlight shining on the panels, thus reducing their productivity. Frequent surface cleaning can significantly improve the efficiency of your solar panels.

6. Long-term financial benefits

At any rate, choosing to install a solar panel can never be a bad financial decision. As any solar installation company would explain, the average payback period for residential consumers on their solar installation is around 4-5 years. This indicates how financially beneficial solar panels are in the long run. The savings incurred on energy consumption by far exceed the upfront costs of the panels.
Investing in solar panels can seem quite daunting, given the huge cost structure upfront. However, with the right choices, you can actually maneuver your way to great savings on your panels.

7 Essential Checks for Metal Roof Maintenance in Solar Plant Systems

by vemcoblogs -
Solar Plant Systems

To make sure your solar rooftop system offers optimum efficiency, you must have a robust maintenance regime in place. Proper inspection and maintenance also help improve the working life of your panels and reduce the costs of depreciation and sudden breakdown. These services are often provided by the same solar energy company that you procure your panels from. 

In This Blog, We Tell You About The 7 Essential Checks That You Must Perform To Ensure Proper Maintenance Of Your Solar Rooftop System:

  • Roof Inspection

Before Solar Panel Installation, make sure your roof would be able to withstand the burden of the mounted solar panels. In case the age of your roof is ten years or more, it is advisable to get it replaced before installing a solar rooftop system. Also, check for any seepages or leakages in the roof. 

  • Cleaning and Debris Removal

Check for any debris in the inverter pad area or elsewhere. Look for any signs of animal infestation such as excreta etc. all over the system and clean it regularly. Wipe the panel surface regularly to remove dust particles that can reduce the output.

  • Gutters and Drainage System

The solar rooftop system must have adequate drainage. Check for any water pooling on the roof and ensure that the drainage is seamless. Any water seeping into the system can cause damage to the equipment, and water on the panels can reduce their efficiency.

  • Sealant and Waterproofing

Mounting a solar rooftop system requires drilling multiple holes into the roofing. This makes waterproofing of the roof essential. This is done by using waterproofing membranes that seal cracks, crevices and seams. For long-term reliability, make sure the waterproofing has been done by a reputed roofer. 

  • Rust and Corrosion Prevention

Rusting can affect the electronic circuits of your solar panels reducing the electricity generated. Besides, corrosion on the outside brackets or racking system can weaken the structure on which the Solar Rooftop System is mounted. Check for rust regularly, use metals that are rust-proof such as anodized aluminium or stainless steel, and ensure complete waterproofing. 

  • Solar Panel Mounting

This is a more physical aspect of the solar panel system. Having a robust mounting structure is necessary to prevent damage to not just your panels but also to avoid accidents and injuries. A weak mounting can lead to the sudden collapse of the entire solar panel installation, which is otherwise expected to last up to 25 years.

  • Structural Integrity

Solar installations must be structurally sound and secure. Check whether the mounting structures are made of durable and corrosion-resistant material. These days, a number of mounting structures with high standards of reliability are available at competitive rates. Look for the warranty provided by the company, strength grade and coating, and the weight that it can support.
