A rooftop solar power, is a photovoltaic system that has its electricity-generating solar panels mounted on the rooftop of a residential or commercial building or structure.
Rooftop solar is increasingly cost-effective for home owners, business owners, and their communities. Reductions in technology prices, innovative financing, and growing networks of solar installers and financial partners all helped drive down the prices for household systems
Many home owners and businesses are taking advantage of third-party ownership options. Under solar leases or power purchase agreements, electricity customers typically pay little or nothing up front for rooftop systems, then get electricity from the systems over a long period at attractive fixed rates. The systems (and maintenance responsibilities) remain the property of the project developers, which may be private companies or electric utilities themselves.
Rooftop solar may have been the fastest-growing segment within India's renewable energy sector last year.
