Eco Solar - Concord Solar Pool Heating Experts -

Doug had done the install on the pool system years ago in our Alamo home and I was fortunate to get his contact information from the previous owner. Our Hayward controller had failed, I called Doug and he was able to contact the manufacturer and get a free replacement!

When it was time for an upgrade to solar we got three quotes and Doug was the hands down winner based not only on pricing but what really sold us is his technical know-how.

Doug looked at our existing system and made recommendations on plumbing changes on the pad for better flow, and since it was a very long run to the panels he made sure to size the piping for most economical operation. Doug's mantra is to make the system run as efficient as possible to save the customer $$, and I really appreciate his attention to detail.

Recently we had some roof work done and Doug's crew was out that day to take care of the changes we needed to make on the panels so the work could continue.

I'm really glad to have met Doug and have his support to keep our pool running smoothly. On top of being an expert at what he does, his customer service is great, he's really a nice guy and pleasure to do business with.

Doug was outstanding! He redid our solar that never worked well. Now it is warm and fully functional. He is smart and creative and really listens. I would recommend him without reservation. It is a pleasure to work with someone who takes pride in his work.

I recently completed a project with Eco Solar and Doug Rotermund and am so thrilled with my experience there that I feel compelled to share. After years of dealing with sub-par solar panel performance, this past Summer I hired Doug to put on brand new solar panels to heat my pool in Walnut Creek. On responsiveness he gets an A+: He answers my calls immediately, and follows through. When I need something, he has someone here within the hour. He came up with a brilliant design for the panels that he created himself and installed: The panels work great and this is the warmest my pool has been in 20+ years. He is conscientious, reliable, and fun to work with to boot! Highly recommend. (Note: This is a 100% voluntary review, not solicited).

Doug's materials, workmanship, value, attention to detail and communication has been exceptional! My system is awesome and heats my pool very quickly and reliably. If I could give him 10 stars I would!

Used Eco Solar recently to replace and upgrade pump and solar panels for pool heating. Works great (super warm water!). Doug was fantastic, patiently answered all my questions and had helpful recommendations. Also won't disappear after the work is done. Good price, great service!

I had a different experience than other reviewers. Not supporting his old customer which are still under warranty. He is busy with new customers and not able to visit for repairs. Also rude and over confident.
