How to Buy Solar Panels

I did something remarkable. I Googled the 'largest solar manufacturers in the world' and found a list of the top ten:

  1. Jinko Solar
  2. JA Solar
  3. Trina Solar
  4. LONGi
  5. Tongwei Solar
  6. Astronergy
  7. Canadian Solar
  8. GCL
  9. DAS Solar

Then I emailed each one to ask about their prices and recommendations for a shingled roof.
