With the 1st discussion on solar power during the financial year 1961-1966, India had a vision regarding electricity generation with renewable resources. Today there are numerous India-based solar companies providing solar solutions on different scales. Come find out which are the top 10 solar panel company in India. If you are considering getting a solar panel system for your rooftop, find out which solar rooftop is best.

What is a Rooftop Solar System?

A photovoltaic system that generates electricity with solar panels mounted on the rooftop of residential or commercial buildings or structures. These modules are small compared to ground-mounted photovoltaic systems with a capacity in the megawatt (MW) range. It includes various components like photovoltaic modules, mounting systems, cables, and solar inverters, along with other electrical accessories. The power capacity of a rooftop solar system ranges between 5 and 20 kilowatts (KW). However, the same system has a power capacity of 100 kilowatts or more in commercial building setups.
