    Scott handled our solar flawlessly. We had some unique shingles and worried we wouldn’t get enough sun to make it worth it. Scott explained to us that not only could they do it, but we would save substantially on our current energy bills. From start to finish excellent service. Highly recommended!

    From begging to end, process was easy and straight forward, thanks to Andres Castaño's commitment, despite a few issues that rose up that almost made me cancel everything, Andres was there each time I called him, and he kept his promise to make things happen and go as smoothly as possible. He always returned my calls within a very reasonable time and got all my questions answered, even when he wasn't working he would never ignored my concerns.

    From start to finish, working with Source Energy Solar was nothing short of exceptional. Their team made the switch to solar ABSOLUTELY seamless — from the very first consultation to the final installation. They truly live up to their mission of helping homeowners save money.

Ordered by how much we can tell you about each, which is not an order of quality. We do not know which of these is better and would not say if we did.

What we don't know

  • The date above is the newest review we hold, which is not necessarily the newest that exists — we hold a large share of Google's reviews, not all of them.
  • We found nothing on a website for this company that states a warranty, a licence or how long it has traded.
  • We do not verify licences, insurance or bonding. Nothing here has been checked against a state licensing board.
  • We cannot tell you what an installation costs, and we hold nothing about the equipment they fit.
