The payback period is the time your solar system takes to recover its total investment through savings on electricity bills. For most residential systems in India, the payback period typically ranges from 3 to 6 years, depending on system size, location, subsidy, and electricity tariff. After this period, all the energy you generate is essentially free.

Solar systems require minimal maintenance. Mainly, you need to clean the panels every 15–30 days to remove dust, bird droppings, and debris for optimal efficiency. An annual professional inspection is recommended to check wiring, inverter performance, and overall system health. With basic care, your solar system can operate efficiently for 25 years or more.

Yes, subsidies are available for residential rooftop solar systems under government schemes such as the PM Surya Ghar Yojana / National Rooftop Solar Portal. The subsidy amount depends on the system capacity and guidelines active in your state. Commercial and industrial projects generally do not receive subsidies but can avail tax benefits.

A rooftop solar system typically requires 80–100 sq. ft. per kW. For example:

• 3 kW → ~250 sq. ft.
• 5 kW → ~400 sq. ft.
• 10 kW → ~800–1000 sq. ft.
