What is a Solar Rooftop System?
A solar rooftop system is a modern energy solution that involves installing solar panels on the roof of a building to capture sunlight and convert it into electricity. This clean and renewable power source helps reduce your dependence on traditional electricity, lowering energy bills and minimizing environmental impact. Ideal for homes, businesses, and industries, rooftop systems are efficient, low-maintenance, and eligible for government subsidies. By using your unused roof space, you can generate your own power, contribute to a greener future, and gain long-term energy savings.
How does a solar rooftop system work?
A solar rooftop system is a clean and efficient way to generate electricity directly from the sun using solar panels installed on the roof of a building. These panels are made of photovoltaic (PV) cells that capture sunlight and convert it into direct current (DC) electricity.
Since most household appliances and electrical systems operate on alternating current (AC), the DC electricity is passed through an inverter, which converts it into usable AC power. This electricity is then used to run various electrical appliances and systems within the home or building.
How to apply for a solar rooftop subsidy?
To apply for a solar rooftop subsidy in India, you need to follow a few simple steps through the official government portals. First, visit the national portal www.pmsuryaghar.gov.in and register using your mobile number linked with Aadhaar and details from your electricity bill. After registration, log in and submit an application by selecting your state, electricity distribution company (DISCOM), and consumer number.
Your DISCOM will then conduct a technical feasibility check. Once approved, you must select an empanelled vendor to install the solar rooftop system.
What is the price of a solar system in India without a subsidy?
The price of a solar system in India without a subsidy varies depending on the capacity, quality of components, and installation location. On average, a residential rooftop solar system costs between ₹50,000 to ₹70,000 per kilowatt (kW). For example, a 1 kW system may cost around ₹60,000, while a 3 kW system can range between ₹1.5 lakh to ₹2 lakh. Larger systems, like 5 kW or 10 kW, typically cost ₹2.5 lakh to ₹6 lakh or more.
These prices include solar panels, inverters, mounting structures, wiring, and installation charges. The cost may be higher if premium panels, branded inverters.
Solar Maintenance
What is the life of a rooftop solar system?
The average life of a rooftop solar system is around 25 to 30 years, depending on the quality of the components and how well the system is maintained. Solar panels, which are the main part of the system, usually come with a 25-year performance warranty and can continue generating electricity efficiently even after that, though at slightly reduced output.
Inverters, which convert the electricity from DC to AC, typically last 10 to 15 years.
Do Solar Rooftop projects have a high maintenance cost?
No, solar rooftop projects do not have a high maintenance cost. In fact, one of the key advantages of solar systems is that they require very low maintenance. The primary maintenance task is cleaning the solar panels periodically usually once or twice a month to remove dust, bird droppings, or debris that can reduce efficiency.
This can be done easily with water and a soft cloth or sponge. In grid-connected systems, there are no moving parts, which means fewer chances of wear and tear. Inverters may require occasional servicing and usually need replacement after 10–15 years. Apart from this, professional check-ups once a year are recommended to ensure optimal performance.
Can Solar projects damage my roof?
solar projects do not damage your roof when installed properly by qualified professionals. In fact, solar panels can protect the portion of the roof they cover from harsh weather, such as rain, sun, and hail, which can extend the roof’s lifespan. During installation, mounting structures are securely fixed with proper sealing to prevent any water leakage or structural issues.
It’s important to ensure that the roof is in good condition before installation, as panels can last 25 years or more. If installed on a weak or damaged roof, repairs may be required first. Also, modern installation techniques like non-penetrating mounts or ballast systems
Do I need to clean my Solar plant?
Yes, you do need to clean your solar plant regularly to maintain its efficiency and ensure optimal power generation. Over time, dust, dirt, bird droppings, leaves, and other debris can accumulate on the surface of the solar panels, blocking sunlight and reducing their performance.
Cleaning the panels once every two to four weeks, depending on your location and weather conditions, can significantly improve energy output. In areas with high dust levels or during dry seasons, more frequent cleaning may be necessary. You can clean the panels using plain water and a soft cloth or sponge avoid using harsh chemicals or abrasive materials that could damage the glass surface.
My roof is not made of concrete; can I still install a Solar Project?
Yes, you can still install a solar project even if your roof is not made of concrete. Solar panels can be installed on various types of roofs, including metal sheets, tin sheds, asbestos, and tiled roofs, using specially designed mounting structures. These structures are customized based on.
For non-concrete roofs, installers typically use lightweight, corrosion-resistant frames and avoid drilling directly into weak or fragile areas. In many cases, clamps or brackets are used to fix the panels without compromising the roof’s integrity.

Our Solar Solution

Residential Solar
Residential solar systems are rooftop solar power setups installed on individual homes to harness sunlight and convert it into electricity using solar panels. These systems help homeowners reduce their monthly electricity bills, promote energy independence, and contribute to a cleaner environment. With rising power costs and attractive government subsidies, more households are switching to solar energy.

Commercial Solar
Commercial solar systems are large-scale solar power installations designed for businesses, offices, factories, and commercial buildings. These systems significantly reduce electricity costs by generating clean and renewable energy on-site. By switching to solar, businesses can lower their operational expenses, achieve sustainability goals, and improve their brand image.

Industrial Solar
Industrial solar systems are high-capacity solar installations designed to meet the heavy energy demands of industries such as manufacturing, warehousing, and production units. These systems help reduce dependency on conventional power sources, lower electricity bills, and ensure a more stable power supply. By integrating solar energy, industries can improve energy efficiency, reduce carbon emissions.
