Which solar company should I choose?

The reviews scores for the largest solar companies are far worse than those for local, family-owned solar installation companies.

The best solar companies meet the following criteria:

  • Local
  • Family-owned
  • Less than 50 staff
  • Has an office near you
  • Been in business longer than 5 years
  • Employs their own installation crews
  • Uses Tier 1 solar panels
  • Uses inverters from Enphase, SolarEdge, SMA or Fronius

The solar industry is full of fly-by-night solar companies — both big and small — that open one year and are gone the next.

Solar panels last for 25-30 years, so you want an installer who will help you with any problems or system faults. For this to happen, your installer needs to be able to stay in business

Local solar companies, as a group, have the highest reviews score on our site and also have lower overheads than corporate installers, making them more likely to survive in the long term.
