The two most important reasons to integrate a solar heating system for your pool are the savings and the environment. A reduction in your utility bill can range from 15% to 50%. Even a 15% "tax-free" savings is pretty good. Making the solar energy decision also reduces the impact of pollution and greenhouse gasses which are detrimental to our health and our environment, as we all know is an ongoing problem.

No additional PG&E costs. The water in a residential pool should be turned over one (1) time each day to properly filter and sanitize the water.

My family first used Alcor Solar when our first pool solar panels were installed in the 90's. We had the roof redone in 2013 and had updated pool solar panels installed then. We recently had Alcor come out to repair a leaking solar panel. They are responsive, honest, and always go above and beyond. And Al is the best :)

I phoned Alcor to purchase a solar pool heating system. I expected that I'd have a long wait until it was installed. A week later, the system was up and running. Really great and fast service. Very reasonable pricing. I give them the highest marks.

Do not use this service. This company is unprofessional and their quality of work is terrible. They don’t provide notice of when they will show up for service calls and then bill you when the problem still persists.

We were referred to Alcor Solar by our pool company and the referral was well justified. When they initially came to our home, they surveyed our roofs for the best panel location and measured the size of the pool to determine the correct number of panels required to heat it. Cliff and Jeff did an incredible job of installing the panels and connecting them to our existing pool system. Not only does the system perform well, it looks great. They completed the installation in one day and cleaned up after themselves when done. I would recommend Alcor Solar to anyone who is looking into cutting the costs

We got solar pool heating installed and every day in the spring, summer and fall our pool is at 80-85 degrees depending on where we set it. In the summer the pool can actually get too warm so we simply adjust the automatic thermostat. They installed it quickly and cleaned up everything spotless. Because I had an older pool pump they needed to order a special part which was hard to find and in 3 days it was installed. I had a concern about the need for them to cut concrete but they were able to tunnel below the concrete so it looks seamless. No more need to heat the pool with gas and my bills have

Installed my pool solar that has now slipped down from the structure due to poor installation. Nails were used instead of lag bolts and they failed. Now they said they can't come out for a year to repair.

My house had very old pool heating solar panels on it. I had my entire house re-roofed and electrical solar installed. Alcor coordinated removal of their old panels before the roofing/solar work, and installed new pool solar panels promptly after the roofing/solar work. I was very happy with their work.

I was redoing a very old solar pool system and found alcor online, They were extremely helpful on the phone and later in person. I bought a bunch of stuff but changed systems and had to return some of what aI had purchased. They were still pleasant and professional. I will return for other purchase related to my solar needs.

Very nice to deal with the business owner and get a fair price (saved over $1000 by going with Al) for our new solar heating system. Everything went according to schedule, the technicians were great, and there were no surprises along the way. Al's team even helped remove an old heater from the 70's and replace some copper pipes to avoid future leaks. I learned alot, laughed alot, and would recommend Al's team to anyone.

I have utilized Alcor Solar on two different homes. Our current home in Walnut Creek was a real challenge and Alcor came through big time. Lots of valleys and rises in our roof, yet they expertly installed 12 panels and the pool runs warm all summer and late into the fall. I would recommend the automatic thermostat...it keeps the pool from getting too warm. We like it at 80 and that is where it stays all swim season. I did use one other local solar company years ago and it was a disaster. Alcor is honest and does excellent work, you will not regret giving the assignment to these guys.

For some reason, Yelp filtered my review. Once again, Alcor gave us the best out of three estimates, did the work in a timely manner, and has had excellent follow-up. Our pool is a larger, older pool and the system keeps it at a pleasant swimming temperature. Please check out my filtered review - I can't say it better than I did before it was filtered!

From my very first contact a month ago to this afternoon (when the job was completed) Al Accurso surpassed all of our expectations. We had to replace our existing solar pool heating (because our roof had failed) and Al offered us an innovative and creative way to do so. In addition, he improved the mounting to reduce problems and improved the plumbing to make our panels more efficient. Everyone in this company whom I've met is a real pro starting with the office manager who is old-school polite, friendly, efficient, to Al who was there every single time he needed to be here plus a couple of

Alcor Solar fixed a cracked end plug and a defective glue joint on pvc fittings to the panel connector. I left a message in the morning and they were out within hours. Diablo Solar had a 2.5 week wait. The technician was friendly, professional, and reasonably priced. I give Alcor Solar my highest recommendation for pool solar units.
