Commercial Rooftop System in India: Commercial Solar Panel Installation

Installing a commercial rooftop solar panel system in India is a great way for businesses to reduce electricity costs, lower carbon emissions, and contribute to sustainability goals. Here's a step-by-step guide to help you understand the process of installing a commercial solar panel system in India:

  1. Assessment and Feasibility Study:

    • Start by assessing the feasibility of a solar installation on your commercial rooftop. Factors to consider include the available rooftop space, its orientation, shading, and structural integrity.

  2. Energy Audit:

    • Conduct an energy audit to understand your current electricity consumption and identify potential areas for energy efficiency improvements.

  3. Regulatory and Permitting Compliance:

    • Understand the regulatory and permitting requirements for solar installations in your area. In India, this may involve obtaining approvals from local authorities and complying with state and central government regulations.

  4. Choose a Solar Installer:

    • Research and select a reputable solar installer with experience in commercial installations. They will help you design and engineer the system, procure the necessary equipment, and handle installation.

Installation Requirements for commercial rooftop

At Mahendra Powertech, 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 -

  1. 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.

  2. 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.

  3. 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°.

  4. 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.

Benefits of Installing Solar Panels on Commercial Rooftops

Here are some interesting benefits of installing commercial solar systems with Mahendra Powertech, one of India’s leading commercial solar installation companies, at your discretion!

#1. You can save lakhs and crores of rupees every year

Solar energy doesn't cost a penny. Yes, there's an upfront installation cost. But, you still save huge chunks of money in the following ways -

  1. There'll be a significant reduction in your electricity bill. That’s because most of your power needs will be met by solar energy from solar systems installed on the commercial rooftops.

  2. If you install solar under the OPEX model, you'll have to pay no more than 4 to 6 rupees/unit for the electricity generated from solar compared to 12 to 14 rupees/unit that you pay to the DISCOM.

  3. You can save money in the form of income tax benefits by claiming accelerated depreciation of 40% per year on the cost of your commercial solar system.

Needless to say that it’s extremely beneficial to pay the commercial solar panel cost rather than paying for expensive electricity as solar is a lifelong investment - the panels last for more than 25 years.

#2. You finally get to achieve the goal of reducing your carbon footprint

Going solar means the least emission of greenhouse houses. Thereby, you're playing a significant part in:

  1. Reducing global warming.

  2. Protecting the planet.

  3. Reducing air pollution.

  4. Reducing the threat of dangerous respiratory and lung diseases.

#3. Satisfying the RPO obligations

Installing solar panels on commercial rooftops will also help you meet and satisfy your RPO obligations (Renewable Purchase Obligation).


1. How efficient are commercial solar panels?

Solar commercial panels are extremely efficient. When arranged in an array, they can power up an entire commercial building single-handedly.

The number of panels you'll need for your commercial building will depend upon your daily electricity consumption. A solar installation expert will be able to give you the best idea about the number of panels that'll be needed.

2. What is the subsidy for commercial solar panels?

None. The government offers a subsidy only for residential solar installations.

3. Why should my company invest in commercial solar?

The many benefits of commercial solar installation are as follows:

  • You'll have to pay no more than 4 to 6 rupees/unit. It's way less when compared to 12 to 14 rupees/unit that you pay to the DISCOM otherwise.

  • You can claim accelerated depreciation of 40% (instead of 5%) per year against the cost of your commercial solar system.

  • You're playing a crucial role in reducing global warming.
