Tata is the Most Trusted and Largest solar manufacturer in India for Home, Residential, and Industrial requirements.. Tata solar plays an important role in making India as a leading sustainable solar power producer country.

Waaree Energies says it is India's largest manufacturer of solar panels, with 12 gigawatts of installed capacity.

Our top choice for the best overall solar company is SunPower. Tesla comes in as a close second, and we consider Blue Raven to be another great option. Installing solar panels from a top-rated company can come with high upfront costs. The initial price can range between $8,000 and $35,000.

Monocrystalline panels typically have the highest efficiency and power capacity. They can reach efficiencies of over 22% and provide over 300 watts (W) of power capacity. Many even exceed 400 W. Polycrystalline solar panels, on the other hand, rarely exceed 17% efficiency and tend to have lower wattages.
