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.
  2. Voltage: This is another important parameter that must be tracked continuously. It also indicates the productivity of your system.
  3. Current: A monitoring system typically has a current sensor that keeps track of the current generated by your solar power system.
  4. Temperature: Solar power systems are known to operate at an optimum temperature. Extremes of temperatures can lead to a reduction in the productivity of your solar power system.
  5. Irradiance: Greater the irradiance received at the surface of the panels, more will be the electricity generation. Suboptimal irradiance may indicate shade due to newly-grown foliage, dust, debris or simply wrong positioning of the panels.

Using data analytics to track performance

Monitoring and diagnostics is all about collecting and analysing data. This is especially useful for identifying performance trends, detecting anomalies and diagnosing potential problems. Analysing data has an important role to play in preventative maintenance, avoiding downtime, and prolonging the lifespan of your solar power system.

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. For more on this, feel free to call us on 022 43436655 or email us at

8 Common Mistakes to Avoid when Installing Solar Projects

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.

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

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. For consultation on sizing your panels, call our experts on 022 43436655 or email us at VEMC is the leading solar installation and consulting company in Mumbai. Get in touch today!

7 Critical Factors Affecting the Efficiency of a Solar Plant

solar power company
solar power company

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.


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

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.


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.


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.


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.

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

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.

6 Reasons Why You Shouldn’t Ignore Solar Metering

Solar Power Company

If you are generating more solar energy than you are consuming, the excess electricity is diverted to the grid and you are compensated for it by deducting the units you purchase from the grid. This simple concept is known as Net Metering.

As any top solar company will tell you, solar energy is gaining a lot of traction the world over and producers must be aware of Net Metering to make the most of their investment in solar power systems. VEMC is a leading Solar EPC Company based in Mumbai.

In This Blog, We Explain 6 Reasons Why You Simply Shouldn’t Ignore Solar Metering:

Lower Electricity Bill

With net metering, you only pay for the ‘net’ amount of electricity that you consume, that is, total electricity imported from the grid minus electricity exported from your solar power system. Besides, the extra electricity units can be used during those hours when sunlight isn’t enough such as at night.

Easy Installation With Fewer Components

There is no need to have a backup generator in net-metered solar power systems. The electricity grid itself acts as one. The lack of elaborate equipment and components makes the net-metered solar system an absolute winner. It also means that the initial costs of installing solar power systems come down significantly. For expert advice on this, get in touch with VEMC –– a top solar EPC company in its segment.

Lesser Environmental Impact

Solar energy is the most preferred unconventional source of energy, especially in terms of environmental impact. But when net metering is added to the equation, it further boosts the environmental benefits as it encourages users to switch to solar energy. Net metering, therefore, helps remove or reduce the reliance on conventional and polluting sources of energy like fossils.

Increased Financial Credit

Net metering provides owners of solar power systems an opportunity to generate revenue by selling the excess units to the grid. This acts as a financial motivator and helps owners increase their financial credibility by creating an asset that becomes a perpetual source of income.

Cost-Effective and Hassle-Free Maintenance

Net metering does away with components like batteries and generators –– the two that require the highest attention and maintenance. Thus, with net metering in place, your solar power systems become more cost-effective and have hassle-free maintenance.

Lesser Network Issues

With the increased number of consumers exporting their excess units to the electricity grid, the chances of blackouts and outages are successively reduced. Issues such as transmission line congestion can be significantly reduced thanks to net metering. An expert solar EPC company like VEMC will be able to tell you more about this.


If you want to install a solar system or have any queries regarding metering, do not hesitate to reach out to us. We will be happy to help you leverage net metering to make your place of work a shining example of the effectiveness of renewable energy.

How To Use Solar Energy in Your Daily Life To Create a Sustainable Earth?

What is Solar Energy in Simple Terms?

Solar energy simply refers to the energy coming from the sun in the form of insolation. When this insolation is tapped and converted into electricity using photovoltaic cells, it is known as solar power. Today, solar power is being put to use in a vast number of ways, be it domestic or commercial. VEMC is the Best Solar Company in Mumbai, with a reputable client base across sectors.

What Are The Advantages of Solar Energy?

• Control Over Consumption ––

For starters, solar energy offers a level of certainty in times when high electricity costs and regular outages have become a feature of the energy market. When the electricity charges hit peak prices, consumers can switch over to solar, and avoid paying hefty sums for their consumption. With a Solar EPC company like VEMC, this has become much more convenient than ever before.

• Green Energy ––

Unlike fossils and other conventional sources of energy, solar doesn’t have a huge impact on the environment. It doesn’t cause air, water or noise pollution. In times when emission-free energy has become the buzzword, solar energy perfectly fits the bill.

• Universal Use ––

The sun is the single source of solar energy and this makes it possible for companies to take solar power to the remotest destinations, where setting up power projects and transmission lines could be a tough ask. Independent solar power systems can make electricity available to local populations and bring about a huge difference in their standard of living. VEMC is hands down the best solar company when it comes to catering to such ambitious projects.

• Energy Buffer ––

If not to replace the main source of power completely, solar can be used to fill in for the hours when electricity isn’t available, outages are frequent, or the prices are very high. Any top solar energy company will recommend these manoeuvres to its clients, helping them meet their cost or operational objectives.

• Improved Grid Security ––

An energy grid widely punctuated by independent solar power systems is less sensitive to blackouts due to say human-made disasters, as consumers can continue to draw power from this alternate pool of energy. A leading solar energy company of the country, VEMC enables clients and partners to enhance their business continuity plans with the help of solar power.

Performance Of Solar Panels In Different Seasons

Your solar panels work best when the sun is shining the brightest, making summer the favorite season. But this doesn’t mean you cannot optimize the generation during non-peak months. By being aware of the factors affecting energy generation, you should be able to boost your solar panel efficiency even during winter. This requires some tweaks in your solar panel installation.

Factors affecting solar energy production:


If your solar panels get too heated up, the photons will dislodge too many electrons from the atoms and get them all ‘excited’. This reduces your voltage and hence also your electricity generation. Overheating clearly is bad for your solar panel efficiency. With every degree above 25 degrees Celsius, the efficiency will drop by about 0.25%. To optimize output, try to maintain the temperature at 25 degrees Celsius.


If a shade falls on just one part of your solar panel installation, you might think that the rest of the panel will work fine and still generate electricity. But that’s not how they work. Cells are connected in series and any obstruction in any part of the panel will affect the flow of electricity overall. So before installing solar panels, top solar companies in Mumbai and beyond will try to avoid the shaded areas as much as possible.

Rooftop (terrace) orientation:

To get maximum exposure to direct sunlight, your solar panels must be mounted at the perfect angle. Since the sun changes its position throughout the day, this angle must change as well. This however can’t be done manually and requires automatic technologies that the hi-tech solar EPC companies in Mumbai and the rest of the country are offering these days.

Cleanliness of solar panels:

Dust, dirt, or water droplets can block the exposure of the solar panel surface to sunlight. This can adversely affect solar panel efficiency. Thus solar panels must be wiped clean at least once a month to ensure maximum output.


Solar panel installation in Mumbai will be different from that in Srinagar or Shimla. The insolation or the amount of energy falling on every cm2 per minute will vary from one location to another. This naturally will have an impact on the energy generated by the solar panels in different locations.

Effects of Rain, Storm, and Cold Weather on Solar Panels:

A high-quality solar panel installation can withstand extreme weather like monsoon rains and storms. The glass layering on the panel doesn’t let the water stand and also protects the solar panels against too much surface heating. However, lightning strikes can damage your panels due to a sudden rise in voltage. Winters are a time when the electricity generation is somewhat reduced, but you can nonetheless use battery backups to store the electricity.

The Importance of Annual Energy Production:

When installing solar panels at home or at your business, taking the annual energy production into consideration is important. Energy production varies from season to season and month to month. So while some days, your panels may not produce enough electricity owing to seasonal or weather-related factors, the overall annual production must be taken into account, while evaluating solar as an alternative energy source.

  • The energy use pattern is collected and recorded by the IoT-based solar energy systems.
  • By detecting motion around the panels, the sensors can also help prevent theft and physical damage to the solar power system.
  • Finally, operators using IoT-based solar power systems can manage the energy demand better and companies can leverage data to distribute energy strategically.

Benefits of IoT in generating renewable energy:

A host of benefits entail from using IoT in generating renewable energy as discussed below:

Automation of processes:

A lot of processes can be automated simply by gathering the right kind of data. This could begin with tasks as simple as the panels of your solar rooftop system being shifted to the perfect angle to allow the maximum amount of sunlight to hit the surface.


Power companies can monitor the usage pattern of households and establishments by using IoT-powered monitoring systems. This will allow them to utilize resources more efficiently to meet peak demand, manage supply based on consumer needs, and effectively eliminate or reduce the wastage of energy.

Seamless grid management:

Utility companies can place their sensors at various locations across the grid to get a fair idea of consumption. With this the companies can also take critical decisions about switching the load, configuring the network, and controlling voltage effectively.

Enhanced safety:

With IoT, companies can ensure better safety of the grid and an uninterrupted supply of electricity to consumers. Sensors, for instance, can alert companies in case of power outages. Likewise, they can also get instant information on damaged lines, electrocutions, and fires.
