Diablo Solar Services Inc

Diablo Solar Services Inc handles solar work out of Concord. They install and service photovoltaic systems, pool heating setups, battery storage, and domestic hot water systems. The company also takes care of residential electrical needs like main panel upgrades. They cover Contra Costa, Napa, Alameda, Sonoma, Marin and Solano Counties and have put in over 25,000 systems since 1984 while staying locally owned and operated.

Homeowners call them for pool solar leaks and panel replacements that get fixed fast. Anthony swapped out micro inverters in under 15 minutes on one job and walked the owner through the serial number updates. Zach, Gary, Joe and Julian pulled panels off a roof before replacement work then set them back on without damage. Hector, Junior and Joe Z handled another reinstall and cleaned up the site. Battery part swaps and full system installs show up in the accounts too with the same crews handling the details.

They respond quick to calls and book estimates within a day or two in most cases. Direct employees do the work with no outside crews brought in. The company takes care of permits and utility paperwork so the owner does not have to chase those steps. Service reaches the listed counties and many reviews note the crews arrive on schedule and explain the fixes before leaving.

Reviews give the outfit a 4.5 rating on Google. Common points include steady communication during repairs, clean sites after pool solar work and long term service on systems first put in decades ago.

“Excellent Service & Outstanding Customer Care I highly recommend Solar Pool Services. From start to finish, their customer service was outstanding—always just "one call away" with prompt, helpful responses. They initially came out to address a leak in my 12-year-old pool solar system. Their assessment was quick and highly professional. They ordered the necessary replacement panel immediately and completed the installation seamlessly. While they were on-site, I asked them to reposition the solar sensor to allow for direct access for future maintenance; they handled the request flawlessly, displaying a fantastic, can-do attitude and making them incredibly easy to work with. Because of their excellent workmanship and top-tier professionalism, I am already planning to have them replace the remaining nine panels of my aging system. If you want hassle-free, expert pool solar care, look no further.”

“Extremely professional, friendly and great communication with the instillation and permit inspection team. Great workmanship, by these very skilled professionals on our pool solar system.”

“Diablo Solar & Electrical Services put in our pool solar panels in 1999 and they have serviced them since then. Theses panels have done an incredible job of heating our pool throughout the years, thanks to Diablo Solar maintaining them. Recently we had to replace our roof. Diablo Solar worked closely with us to take the panels off and put them back on right before and right after our roof was replaced. The crew did an amazing job! They were super polite, friendly, knowledgeable, professional and considerate. Zach, Gary and Joe took the panels off. They carefully placed them in our yard and did not damage a single piece. Zach and Julian put the panels back on our roof perfectly. They look beautiful and are again heating our pool flawlessly. They helped to make our roof replacement so much easier and I truly appreciated their hard work. I would highly recommend Diablo Solar Services!”

“Two micro inverters went out on my solar panels and luckily the Enphase warranty covered the defective parts. I contacted Diablo Solar to arrange to have the micro inverters swapped out. The technician (Anthony) arrived at my residence and within 15 minutes both micro inverters were replaced! He also spent time explaining how he would enter the new serial numbers of the micro inverters into my solar array system. Within 30 minutes, my solar system reflected the new serial numbers. I was impressed by Anthony’s customer service and his very quick repair to my solar panels. Great work! I will utilize Diablo Solar on future Solar repairs.”

“Got a referal from Paradise Pool in Napa about Diablo. I went online and scheduled an appt. I was called by them within 15 minutes. Great communication from them immediately. Estimator scheduled. They called to check in with me the day of estimate. He was very friendly and honest. Told me he would have estimate to me in two days. He did. The i stall crew did a high quality install. Neat and clean and well organized. They ran me through the operation of the system and made it simple for me. I HIGHLY recommend this company. I did contact another company before Diablo. They said i would see quote in 3-5 days. That was 4 months ago. I have still not seen anything from them. Please use Diablo and nobody from the Santa Rosa area.”

“We LOVE using Diablo Solar! Everyone is so nice and professional! The gentleman that comes to our house is so friendly and always has a smile on his face. He lets us know when he arrives and when he’s finished. We had a new roof put on, so Diablo Solar came out and took off the solar panels and when the roof was done they were back putting them back on. Everything went smoothly! Highly recommend!”

“Very happy with Diablo Solar experience with our pool solar heating. Price was very good and interaction with salesman was positive - very clear with the cost and process. Installation went very smoothly. It helped that my pool person had experience with system and he helped me get the system scheduled in a very efficient manner - I didn’t get as much information about how to schedule things with company rep as I had hoped.”

“I had Anthony with Diablo Solar come out to check out my solar in Walnut Creek. The found out my inverter is under warranty and went through the process to order a new one for me and they will install the new one and get me back up and running. Very professional and great customer service. Diablo Solar is now the company I will refer to friends and I will use. Thanks.”

“We have been doing business with Future Energy for 20 years and have purchased two solar units from them during that time. Our experience with Walter was just as all encounters with Future have been. He was completely professional and accomplished troubleshooting fairly quickly for a difficult issue. He had prepared by having the part needed, and installed that and had our unit working again within 30 minutes. All that and he was friendly on top of it.”

“Having East Bay Power Systems design, install and certify a rooftop solar panel system has been a wonderful experience. Working with the team (Darlene, Jeff, David etc.) to get the system designed and installed was very easy, they took care of everything, including getting the city to approve the design/installation for PG&E. Installation was a simple one day process, and best of all, we were essentially off the grid the next day. Interestingly East Bay Power Systems use American made solar panels (Aptos) and an American made power backup system (Tesla). Not only does the system perform flawlessly, because of the high output of the Aptos solar panels (up to 450W per panel) the whole array of 10 panels is virtually unseen. As an added bonus, they set up a Tesla app on your phone so you can see at a glance how mush power the system is generating, how much is being used to power the house, how much is used to charge the backup system and how much power is being sold to PG&E. For a system this good, overall cost was relatively low, far less than what I was quoted 5 years ago by two different companies. You may have noticed all my reviews to date on Google have been 5 star, this is del”

“Diablo Solar is an amazing local company. Every person I have spoken with has been super knowledgeable. Most recently, I had to have a part in my battery replaced. Anthony was our technician and explained everything. He also provided helpful suggestions for how to use my battery more effectively (and rely less on PG&E).”

“The were very efficient and friendly. They discussed the work to be performed and how long the project would take. I have been a client for greater than 12 years. I have never had a bad experience with management or staff. Thank you!”

“On April 21, I had my Diablo Solar reinstall my pool solar. I was very impressed with the professionalism of the workers that came out. Their names were Hector,Junior and Joe Z. When they showed up, they got right to work and when they finish, they cleaned up after themselves. They were very easy to talk with and any issues I had they took care of immediately. Thank you for such great service.”

“Diablo Solar installed my original pool solar heating system 12 years ago and they just replaced the system with new panels. Nothing lasts forever. I was happy with the work and knowing they were still in business meant that they are continuing to do good work for there customers new and old.Highly recommend them!!”

“Diablo Solar is always the best. Great work. They installed my panels 12+ years ago, and both of us are still here! Very nice, knowledgeable, professional staff. They get the job done.”

“Diablo Solar is a great outfit. Everyone is professional and knowledgeable. The take care of our pool solar heating system and have replaced older failing panels. I highly recommend them.”

“They got the job done at a price I can live with. However, communication with the sales rep and office staff is pretty bad. They're slow to return calls and after the work was completed stopped responding at all. I had asked the sales rep to include a cleaning which never happened and the original quote was verbal so.. yeah. The crews that came out were nice but each one gave me conflicting information about my panels and the efficacy of cleaning them at all. Despite asking each crew every day about a cleaning, it again never happened. My overall take is that Solar is far too unregulated and I don't trust the people I have met in the industry. Seems alot like many emerging industries where a lot of bad actors operate. Sadly these folks seem to be the best in the area, so just don't expect much and you'll be fine.”

“Easy to schedule the appointment. I did not hear from them prior to showing up or when it was completed. Just got a bill a few days later. Would have been nice to hear what went wrong and they completed the fix.”

“Diablo Solar met every expectation! In today's world, scheduling a service appointment with a trades company is always a "crap shoot." Never a call back, the job is too small, the service window of 2-5 hours is never honored, and overall the experience results in frustration. Call me back, show up on time, and charge me a reasonable price...golden! Kudo's to Diablo Solar for meeting and exceeding expectations. Customer service was 5 star!”

“I had my pool solar system checked and leaks repaired. This is the second time ive used Diablo Solar and both times I couldn't have been more pleased with the work. I highly recommend this company for having great technicians and quality workmanship.”
