Commercial Rooftop Systems in India: Commercial Solar Panel Installation
99 times out of 100, commercial rooftops remain unutilized. Installing solar panels is the best way to put to use this space.
Installing a solar system on commercial rooftops means you won’t have to pay rates as high as ₹12, ₹14, or ₹16/unit any longer since solar energy is free after the successful installation of solar panels! It can reduce your electricity bills by more than 70%.
EarthWaves is one of the leading commercial solar installers in the country. Our mission is to make solar adoption easier and reduce electricity costs for our customers.
Whether your rooftop is an RCC terrace or a metallic sheet roof, we install different types of commercial rooftop solar systems that’ll be apt for your roof.
Even if the rooftop space is limited, we offer both commercial rooftop solar systems with net-metering and captive power plants without net-metering to take care of all your energy requirements (even if those requirements are very high).
Installation requirements for commercial rooftops
At EarthWaves, we take care of all the commercial rooftop solar panel installation requirements right from the evaluation stage to installation.
A successful installation of solar systems on commercial rooftops has the following mandatory requirements –
- Roof inspection for strength – A commercial rooftop solar system easily imparts 15 kg/square meter of load on the roof. We ensure your roof is strong enough to not collapse under such a degree of load.
- Type of roof – If you have an RCC roof and would like to continue to utilize the area for other purposes, you require elevated hot-dip galvanized steel mounting structures. If you have a metallic sheet roof, you require aluminum rail structures that are light, sturdy, and corrosion-resistant.
- Slope, direction, and mounting angle – Solar panels provide the best generation when the roof slope faces Southwards. The spot for the installation of commercial solar panels should ideally stay shadow-free between 9 AM to 4 PM. The ideal tilt angle for solar panel installation on commercial rooftops in South India is 10°. The ideal tilt angle increases as you move towards North India, and should be above 20°.
- Easy access to the rooftop – There should be safe, direct access to the commercial rooftops so that installers can carry all the raw materials for solar panel installation safely. Post the installation, regular fortnightly maintenance also requires a safe passage.
How does the commercial rooftop system work?
A commercial solar system is a careful setup of many components. Each component plays a significant part in the conversion of solar energy into electricity in order to power commercial/industrial buildings.
- An array of solar panels is installed on commercial rooftops at the most accurate angles.
- The PV cells in the solar panels absorb sunlight and convert it into DC current.
- The direct current (DC) is fed into the solar inverter and converted into alternating current (AC).
- With net metering: The A C power is fed into a bi-directional net meter.
- Without net metering: The AC power generated is consumed within the building. It doesn’t require a bi-directional meter.
- Solar power generation is at its maximum capacity during the daytime from 11 AM to 2 PM. Once supplied to the meter, the excess power is exported to the DISCOM. The exported units as measured by the net meter are subtracted from your electricity bill.
- During the evening and the subsequent hours, power is imported and used to keep the commercial building running even after the Sun has gone down.

Solar Economics
General
Why should I go solar?
If you want to save money from the sun, Solar is the best investment for you. Solar allows you to save on your monthly electric bills plus it also allows you to save the planet by going green. Solar energy is a true form of renewable clean energy which leads to zero pollution (air, noise, land) and emits no greenhouse gases mitigating climate change.
Is solar power safe?
Yes. The electricity produced by a solar power system is no different than the electricity you get from your electricity distribution company. The only difference is the source. Moreover, it is among the safest source of electricity consumption because it is neither hazardous nor does it release any toxic or harmful gases during production.
What is a rooftop solar system?
You can use the empty space on your roof to install a solar system which will convert sunlight into electricity for your house or building. Such a system is referred to as a rooftop solar system.
What do I need to install a rooftop solar system?
All you need to qualify for a solar system is – empty space on your roof and access to your rooftop. Just fill the project enquiry form on our website and our team will contact you to discuss your requirement. Once the project is finalised, we will take care of your entire plant design, installation and maintenance.
Solar Maintenance
What is the life of a rooftop solar system?
The Solar Plant life is 25 years. The main components are solar panels and inverters. Solar panels have a warranty of 25 years and inverter warranty ranges from 5-12 years.
Do Solar Rooftop projects have a high maintenance cost?
A Solar Rooftop module comprises minimal moving parts and hence has very low maintenance cost. SolarSquare Energy provides first 5-year maintenance free of cost to clients ensuring a hassle free experience for all our customers.
Can Solar projects damage my roof?
SolarSquare Energy has a UL certification (one of the highest quality and safety standards in the world) and ensures that no damage to the existing structures takes place during the installation or running of the solar plant. We use a multitude of techniques like non-penetrating structures and waterproofing solutions to ensure your roof�s integrity.
Do I need to clean my Solar plant?
It is a good practice to clean the solar panels 1-2 times a month. It is safer to clean the panels early in the morning or at night when no incident sun rays are present and the power plant is not producing any electricity. You can simply use a clean wet cloth, soft nylon brush or sponge to wipe the surface but ensure the panels are clear of any moisture. Don�t use metal brushes or detergents as these may streak the glass of the panel.
Solar Economics
How much does a solar Plant cost?
The cost of a solar plant depends on its size, configuration and degree of supporting structures required. We provide you multiple options to choose from, designed specifically to meet your requirements.
What is the break-even period for Solar rooftop projects?
Rooftop solar projects are among the most lucrative investments for industrial, commercial and residential projects. The breakeven is achieved in 2-4 years itself, while you enjoy savings for the project life of 25 years.
Are there any subsidies provided by the government for solar projects?
There are no subsidies available for commercial entities. For residential rooftop solar projects, subsidies are released by state governments intermittently. Whenever subsidy is applicable, SolarSquare Energy provides it upfront to the customer in the project cost itself. At present, the Madhya Pradesh government has released a lucrative solar subsidy for the residential sector.
How do I avail subsidy provided by the Madhya Pradesh government?
SolarSquare Energy provides the subsidy upfront as a direct discount to the consumers to ensure a hassle free experience.
