Top Rooftop Solar Installation Companies in India

Lack of relevant information and awareness about the benefits of going solar are major bottlenecks in the rapid adoption of rooftop solar in India. People end up paying high power tariffs because they are not comfortable incurring large upfront cost of buying solar panels and other equipment. Lack of standard products, procedures and the absence of easy financing options from banks has resulted in a slowdown in the rooftop sector. With cost of solar coming down drastically, it is now possible to recover the cost of rooftop solar in 5-7 years’ time (note this depends on many factors like subsidy, electricity bill, tariff, units consumed etc.)


According to Bridge to India, households account for only 9% of the total rooftop solar capacity in the country and a majority of the rooftop installations in the country are on commercial or industrial establishments. However, given the rising demand for power in the country, rooftop solar is the only viable option in India. Let us have a look at the country’s top rooftop solar installers.
