A solar rooftop system uses photovoltaic (PV) panels installed on your roof to capture sunlight and convert it into electricity. The inverter converts the DC electricity into AC, which powers your home or business. If excess energy is generated, it can be exported to the grid through net metering.
Savings depend on your energy consumption, system size, and electricity tariff. On average, a rooftop solar system can reduce your monthly bill by 60–90%. Over 20–25 years, the lifetime savings can amount to several lakhs.
Most residential and commercial solar systems in India achieve payback in 7–9 years. After that, the electricity you generate is practically free for the remaining system life.
Yes. Solar panels still generate power in diffused sunlight, although at lower efficiency. With net metering or hybrid systems, you’ll have continuous power supply even in cloudy weather.
High-quality solar panels typically last 25 years or more. Inverters generally last 8–12 years and may need replacement once during the system’s lifetime.
Yes. The Government of India offers subsidies for residential rooftop solar under various schemes (up to 40% depending on system size). PureSun India guides you through the application process.
Solar systems are low-maintenance. Regular cleaning of panels (to remove dust and debris) and periodic inspections ensure optimal performance. Annual servicing by professionals is recommended.
No. When installed by certified professionals, solar panels are mounted securely without damaging the roof. In fact, they can protect the covered portion from direct sun and rain.
Yes. Solar systems are scalable. They can power small homes, large villas, offices, factories, or even commercial complexes. The system size depends on your energy consumption and roof space.
You can choose from:
- CAPEX (buying outright) – You own the system and enjoy full savings.
- EMI/loan options – Spread payments over time.
- PPA/Lease models (for businesses) – Pay for energy consumed, not the system.
