West Coast Solar Inc

West Coast Solar Inc takes on solar work for homes and businesses in the Concord area. The company has run since 2007 and focuses on panel installations along with battery storage to cut down on PG&E bills. They handle both residential jobs and larger commercial projects, including system design, financing setups, and warranty service requests. The operation covers Northern California with options for zero down payments on new systems.

Customers describe full installs where teams managed permits from start to finish and left clean setups that produced as expected. Inverter replacements show up often, with techs such as Ryan, Gabe, Travis, Cliff, Josh, and Craig handling diagnostics, part swaps, and remote monitoring fixes. Battery connections and array troubleshooting also come through in the feedback, along with cases where crews reworked roof placements after initial errors or coordinated with outside providers to speed up parts delivery.

They schedule free consultations and let owners build systems online before work begins. Some reviews note prompt arrivals for service and clear explanations during visits, while others point to weeks of delays on repair calls, unreturned messages, and repeated rescheduling for inverter work. The company lists 4200 plus completed installations and operates with claimed status on directory listings, though response times vary based on the volume of service requests in the area.

Feedback shows a 4.3 Google rating with recurring notes on knowledgeable crews during installs and solid results once systems run, mixed with complaints about follow up on warranty items and communication gaps after the initial work.

“West Coast Solar installed my system several years ago and have been fantastic to deal with. Over the years we’ve had 2 occasions to need them to come out and their customer service, as well as their technicians, are gracious and know their stuff! Highly recommend them!”

“Ryan, Gabe, and Travis along with all of the West Coast Solar Team were all very supportive and knowledgeable throughout the whole process of having our Solar install led for our home. I chose to work with West Coast Solar and their Team because of my in-laws used West Coast Solar and they treated them with up most respect and support. Ryan and his Team made the process easy and hassle free for my wife and I. They handled everything Start to Finish. Scheduled all of the Appointments and Permits. Day of installation was perfect no problems clean installation and we'll designed system. My wife and I will recommend West Coast Solar to anyone that is interested or looking to get Solar.”

“The sales and installation process were fine, but since my solar system stopped working months ago, the customer service has been completely unresponsive, with many false promises regarding fixing my system. I wish I had chosen a company that cared more about their customers.”

“West Coast Solar helped us quite a bit. They were the installers of our solar but we ended up inheriting a service contract with Spruce (Real Estate Agents didn’t do any paperwork for Spruce, only West Coast Solar) when we purchased the property in 2020.. West coast Solar was set to come to our home in November of 2025 to replace a broken inverter, they found that we had a service Contract with Sprucepower. They went out of their way to help me to get Sprucepower to not move so slowly to go through their processes. The inverter is now at my property as West Coast Solar had my part and arranged to have me come and get it! I will be buying out the remainder of my service contract with Spruce and have West Coast Solar service it if needed. I highly recommend West Coast Solar!”

“I purchased a solar system from West Coast Solar in Brentwood CA. I have a solar panel that is under warranty and West Coast Solar has refused to honor the warranty contract I have with them to fix/replace the panels and will not respond back to multiple service requests and have now said to have my attorney contact them. I would never recommend doing any business with West Coast Solar based on the poor customer service I have experienced and lack of professional service from management and owner/CEO. *** response to owner response to my review... I have tried several times to try and get the service visit accomplished. West Coast Solar has refused to respond to my numerous request via email and phone calls to try and rectify the issues. West Coast Solar has not responded to my warranty request. There is a material disagreement in the 25 year warranty where as West Coast Solar is trying to change the terms of the original contract and forcing me to sign and agree to these changes in order to receive the repair under the warranty. This I feel is unfair and should revert back to the language of the contract. This is where West Coast Solar is bullying me as their customer and refusing”

“Cliff with West Coast Solar is AWESOME!! Polite, courteous, friendly and approachable! He explained the processes very well, checked in with me before, during and after he had finished. What an asset to the company! Give him a raise! 👏🤩 Turns out we needed a new inverter and Josh, the service tech was also AWESOME! Communicated every step of the way, arrived promptly on time, checked with me mid-process and upon completion. Efficient, courteous and expert service! 👏😃”

“I like to thank Rob for the excellent customer service provided, he worked on 2 EcoFlow solar installations on my son’s homes. First one is perfect. But 2nd one has intermittent issues that requires immediate diagnosis when it happens, this is where Rob shows his excellent commitment to customer services. I called and text him after hours, during weekends and he always responded right away and be able to monitor the system remotely and worked with us on diagnostics, without him, it will be very difficult to figure out due to it’s a new and smart system that requires technical knowledge to understand what the system alerts are. Rob has excellent knowledge and always provided logical explanations on what to look for next. I would give a 5 stars review, but I felt the office did not take into account that how much time required to complete a installation, and took on too many orders at the end of last year. Even the service from Rob is excellent but the installations on both houses need multiple visits that spanned more than a week, the sales, planning and scheduling has rooms to improve, so the back office get a 3 stars and averaged out as 4 stars. There are other team members I met ”

“I am providing the latest update on the installation of my system which has still not been completed by Westcoast Solar since the original installation of sept 2024. I REALLY DID NOT WANT TO HAVE TO GIVE ANOTHER BAD REVIEW. HAD THEY FOLLOWED THROUGH COMPLETELY, I WOULD HAVE PROVIDED A REVISON THAT I WAS COMPLETELY SATISFIED. BUYER BEWARE LOOK AT THE RATINGS OF 1 STAR ON ALL REVIEW APPS. THEY ARE MORE THAN LIKELY TRUE. This company is horrible to deal with. They never configured my arrays so that I could monitor the output for each panel. I don't know if panels are producing correctly now or not. I have contacted Enphase to ensure that this was supposed to be done in of the 5 step commissioning process. I have been trying to get them to remedy this issue since June of 2025. I just get answers back like this. That is if they reply at all!!! Here is the response I have finally received for a problem the should have a response to immediately. Just a quick update to let you know that I’m still looking into your request (5329). I want to make sure we resolve this properly, and I’ll reach out again once I have a meaningful update to share. They know what the issue is. I have already ask”

“Updated 5/6/26- I received an update from Christina Ramirez, Director of Customer Experience, regarding my service request. It appears my initial request was somehow unassigned, which unfortunately led to the delay in response. Once contact was made, I received very prompt and professional assistance from Gabe, who worked with me over the phone to troubleshoot the issue and attempt to reconnect the Powerwalls to WiFi remotely. Although the issue could not be fully resolved remotely, Gabe coordinated for a technician, Craig, to come out the very next day. Craig was able to successfully fix the issue and reconnect my system, which had not been functioning remotely. I’m very satisfied with the swift resolution once communication was established. There was a tremendous effort on West Coast Solar’s part to quickly address and resolve the issue, and I greatly appreciate the professionalism and responsiveness shown by the team. I think one area for improvement would be the response process once a service request is received to ensure there are no gaps in communication or requests unintentionally going unassigned. Better communication during the initial stages of a service request woul”

“The technician who finally arrived at my house five weeks after I contacted West Coast Solar, did a great job replacing the inverter. The level of service from West Coast Solar as a company has a lot of room for improvement. Five weeks without Solar is not acceptable. I made many phone calls that were not returned, and I felt like I was getting the runaround. In the end, solar edge sent the inverter to West Coast Solar, who scheduled the work, then reschedule the work, then reschedule the work again! The technician was confident and professional, but it was five weeks until he showed up”

“I bought solar from westcoast solar in 2022. Recently my inverter went bad in September 2025. I contacted them in November and they said they would handle it. Heard nothing from them for about a month which my pge bill is going up because of no solar and I try to contact tuem and you speak to someone. The phone operator you speak to isn't even in the country from the heavy accent I assume. All emails we have sent have been returned to sender. Either this company is severely mismanaged or they scam people.”

“It has taken over four months from deposit to passing city inspection. Most of the installation was initially unsatisfactory and had to be redone resulting in probably three weeks delay overall. However, the end result is super nice. The office staff and the field workers were always polite and cooperative. I suspect that things would likely have gone smoother if the work flow was more normal, however, with incentives about to expire everyone was under pressure to complete a heavy workload.”

“3 of the last 4 years, (this year is the 3rd) I have had an issue with something with our solar. Each of those issues, were poorly followed up with any sort of response from WCS customer service/team. I have had to resort to sending frustrated emails to the Tamayo family (owners) members in order for a rep to reply to me. Every time. WCS' customer service is that bad. This latest issue they denied accountability in their communication. The attached photo shows them sending a text to an incorrect number (in their defense, they said it's my old number - true, old. But ever since the 1st issue 4 years ago, this was supposedly updated by their rep). The message didn't go through. It clearly says, MESSAGE NOT SENT. Yet, they said "you confirmed this appointment per our phone conversation". Something that was never made. WCS' customer service is horrible. Please train or get rid of those with the CSR title because clearly they don't know what they're doing. If you're going to use automation with your services, please learn how to use them properly. Do better. Unfortunately, I'm stuck with y'all until I pay this system off. I hope I don't have to send another service request next year”

“Clif was informative, succinct on procedure and in and out in good time. Very pleased with his work.”

“West Coast persevered to get replacements for my inverters. The real magic came from Cliff, he diagnosed and then installed the replacements. Everything is rocking now. Thank you.”

“He was on time, very quickly made the changes and verified the system performance. After completion, we had a discussion about solar/batteries in a very relaxed atmosphere. Great job West Coast Solar.”

“My inverter replacement occurred as scheduled and the installation went without issues.”

“Working with West Coast Solar was a breeze. I was a referral customer and worked with Ryan. Did a lot of comparison shopping and West Coast was the best no hard sell. Installation was clean and looks great. I highly recommend them for your solar project. System produces what was calculated”

“Working with WCS has been an absolute nightmare. I wish I would've gone with any other solar company. A really good friend and fellow business owner recommended WCS because his friend was one of their sales people. He's a really good sales man, as he sold us on going with WCS instead of the company I had originally wanted to go with. He basically matched their pricing, and then told us that we would get personalized service and never have to go through a third party or deal with the manufacturer, because they would take care of it all for us. That was a huge selling point for my husband and I, as we love supporting locally owned companies, let alone we were dreading having to use third-party installers for the other company I had spoken to. That was the last bit of goodness we ever received. Our installation was pushed back multiple times, over almost 3 months. I had to keep calling and asking when we would be receiving service. Then we were told our installation wasn't as important as some other issue that another homeowner was having, so they pushed us out another 3 weeks. The staff in the office all spoke down to me as if I was stupid and made me feel like I was somehow gettin”

“West Coast Solar Review While the initial sales process with West Coast Solar was professional and well-organized, the installation phase was severely lacking in execution, communication, and accountability. Despite being assured that all work would be completed by in-house crews, the installation was plagued by missteps. Panels were installed on the incorrect section of the roof—directly beneath a tree—contrary to the approved design. This error not only compromised system performance but also led to multiple delays and two failed city inspections. Additional issues included: Incorrect Roof Installation: Panels were placed on the wrong roof, requiring a complete rework and delaying the project significantly. Roof and Property Damage: We have several broken or chipped tiles, one missing tile, glued tile repairs, and damage to an existing pool solar panel—none of which were present before installation. Inspection Failures: The system failed two inspections due to avoidable mistakes, extending the project timeline unnecessarily. Substandard Workmanship: Sloppy details such as crooked electrical boxes and the failure to implement required corrections reflect a troubling lack of c”
