The 7 best solar companies of 2022 – MarketWatch


Tesla Energy

  • Warranty: 25 years
  • State availability: 50

Tesla Energy provides advanced solar panels and installation nationwide either by company technicians or through the Certified Installer Program, a network of some of the nation’s highest quality local and regional installation companies. 

Tesla stands out for its in-house designed products, including its integrated solar battery system, Powerwall, which is considered among the best batteries in the industry. 

The company takes a sophisticated and modern approach to solar power through the design of panels that are sleek and unobtrusive while still remaining relatively affordable. Tesla installs its own brand of high-quality solar panels that are low-profile and have a concealed edge and no visible grid.

After surveying your roof’s area and slope remotely using aerial technology, Tesla Energy can create a custom system that fits your roof and specific sunlight exposure levels. Tesla also designs a completely solar roof by installing solar shingles that blend with the overall look of home exteriors.
