    I do not normally leave negative reviews, but after nearly 10 years, I feel it is important to…read moreshare my experience. Before posting this review, I made every reasonable effort to resolve these issues directly with the company. I sent a formal letter over a year and a half ago outlining my concerns and requesting assistance, but I never received a response. More recently, I sent another detailed email, giving the company 14 days to respond with a plan to address these longstanding issues. That deadline has now passed, and once again, I received no response. This company installed my solar system in 2016. At the time of purchase, I was given expectations regarding the amount of energy the system would produce and the savings it would provide. Unfortunately, those expectations have never been met. In nearly ten years, my system has never produced the level of solar energy that was represented when I made this investment. As a result, I have spent thousands of dollars out of pocket on Southern California Edison bills that I reasonably expected my solar system would significantly reduce. Instead of receiving the savings I was promised, I have continued paying far more for electricity than I ever anticipated. What has been most disappointing is the lack of follow-through. The company has been aware of issues with my system for years, yet they remain unresolved. Despite numerous phone calls and emails over the years, I have received little to no communication, no meaningful updates, and no proactive effort to correct the ongoing problems. There were also issues from the very beginning. When my system was installed in 2016, I was never provided with the monitoring equipment that was supposed to come with it, nor was I informed that there was a monitoring app available. Without those tools, I had no way of monitoring my system's production or knowing that it was consistently underperforming. After years of phone calls and emails to the corporate office, I finally got someone to come out in 2023 to install the monitoring equipment that should have been installed from the beginning. It was only then that I learned there was an app that allowed me to monitor my system. During that same visit, the technician determined that my microinverters needed to be replaced. The replacement microinverters were shipped to my home, and the technician returned to pick them up for installation. However, the work was never completed. The technician left with the new equipment and never returned to finish the job. Despite additional attempts to follow up, I was once again left without answers or a resolution. I understand that mistakes happen and that every company occasionally encounters challenges. However, this is no longer a matter of a simple mistake or a temporary inconvenience. This has been an unresolved issue for nearly a decade. My goal has never been to leave a negative review. My goal has always been to have the solar system I paid for perform as it was represented and to have the company stand behind its product and installation. Unfortunately, after almost ten years, thousands of dollars in unexpected utility costs, years of unanswered phone calls and emails, an incomplete repair, and two formal written requests that went unanswered, I have been left with no meaningful communication and no resolution. I sincerely hope this review encourages the company to finally contact me, complete the repairs that should have been completed years ago, thoroughly evaluate my system, determine why it has consistently failed to meet the promised production, and stand behind the product they sold me. If the company reaches out with a genuine commitment to resolving these issues, I will gladly update this review to reflect that experience. I would much rather write about a company that ultimately made things right than one that chose not to.

    I am writing to formally file a complaint against UniverCity Solar LLC, located at 242 East Airport…read moreDrive, San Bernardino, CA 92408, regarding unresolved roof damage, ongoing water intrusion, broken promises, and what I believe to be negligence and misrepresentation that dates back to 2022. UniverCity Solar has visited my home on two separate occasions over the past several years to address a roof leak that developed after the installation of their solar system. During those visits, their technicians identified cracked roof tiles as the cause of the leak, repaired those tiles, and sealed the affected areas. Despite these repairs, the roof leak continued. In January 2023, I communicated directly with Aaron, a representative of UniverCity Solar, who acknowledged the damage and promised that the company would repair the interior damage caused by the leak, including repainting the roof area stained by water intrusion. Aaron repeatedly delayed this work, citing a lack of available personnel, but reassured me multiple times that the repairs would be completed. At one point, he even stated that he intended to hire a professional painter to perform the work. Trusting these assurances, I waited in good faith for over a year, during which time no repairs were made. In late 2026, heavy rains resumed and caused additional damage, including deterioration to the drywall and window sill in my dining room--the same room originally affected by the roof leak. On December 3, 2026, UniverCity Solar sent Adam to inspect the roof. At that time, they claimed to have discovered damage to a board outside the solar panel areaand abruptly stated that they were no longer responsible for any repairs. This sudden reversal is unacceptable. Regardless of any newly identified issues, UniverCity Solar previously diagnosed the leak twice as being caused by cracked roof tiles, which they stated were responsible. I relied on their expertise and professional assessment. If their current claim is that the cracked tiles were not the cause, then the company is still responsible for misdiagnosing the issue on multiple occasions, which directly resulted in delayed corrective action and increased damage. Due to the age of the damage and the prolonged delays caused by UniverCity Solar, I am now unable to file a homeowners insurance claim, as the issue is no longer considered new damage. Their failure to correctly diagnose and permanently resolve the problem has directly hindered my ability to seek insurance coverage, resulting in financial harm. Additionally, I am deeply disappointed to learn that Tim, the salesperson who sold me UniverCity Solar's services, misrepresented the company's roofing credentials. I was told that UniverCity Solar carried a full roofing license, only to be informed later by Aaron that they carry only a limited roofing license. This discrepancy further undermines my trust in the company. I am especially disheartened by this treatment given that I have provided over three referrals to UniverCity Solar, all of whom became paying customers. This level of neglect and refusal to honor written and texted commitments--copies of which I possess--is unacceptable and does not reflect the service that was promised to me. At this point, I am unsatisfied and disappointed with UniverCity Solar's conduct and believe their actions constitute negligence and potential malpractice. I am requesting that UniverCity Solar be held accountable for: * Honoring their written and verbal commitments * Repairing the interior and exterior damage caused by the roof leak * Addressing the ongoing water intrusion issue in full I processed additional complaints to the Federal Trade Commission report number 195345513 and the Better Business Bureau under the Pacific Southwest, Central & Inland California division.

    This experience was exceptional! The company that installed my system has gone bankrupt so Tesla…read moredirected me to its trusted installers in the area. I picked Option one right at the top. Natasha was professional and very clear with communication from the start. She set proper expectations on communication with Tesla would take a week or two. The day she received the go ahead from Tesla she called and scheduled the install asap 4 days out. Later the same day they had a cancellation and were able to get everything scheduled the next day. Anthony and Jeremiah arrived at the beginning of the arrival window! They were professional, great with communication, and ready to work. I had several questions and they were prepared for all of them and super helpful. The battery removal and install took less than an hour. Naturally Tesla's update took twice as long. LOL. Still total time was under 3 hours. I have managed 100s of installers and worked in Solar, this was a fantastic expierence! Because the Tesla 3 has more storage than the 2 I asked about adding some of my Breakers to the back-up and they had options for us to do that. Obviously we Highly Recommend This Team!

Scott & Ivan have been working on resolving this issue that is on Tesla's end & have been keeping me in the loop. They both have been communicating with me on the progress of my work order. I really appreciate their dedication to getting things done & finding a resolution to this issue. I will update again after this is done.

    I had the opportunity to meet with Oscar Hernandez regarding a solar battery system, and I was very…read moreimpressed with his knowledge and professionalism. He took the time to thoroughly explain how the battery works, its benefits, and how it could help improve the efficiency of my solar setup. One thing I appreciated most was how clearly he explained why my electricity bill has continued to increase each year, even though I already have solar panels. He made the information easy to understand and answered all of my questions without any pressure. Semple Solaris also offered a low-interest payment plan, which made the investment much more manageable. I would definitely recommend scheduling a consultation with Oscar. He is knowledgeable, patient, and genuinely takes the time to educate his customers so they can make informed decisions.

    I want to clarify something for anyone reading these reviews…read more The responses you see from this company give the impression that they're actively working to resolve customer issues. That has not been my experience. What I've seen is a pattern--public replies that look helpful, requests for your information, and then little to no meaningful resolution. It feels more like they're covering themselves on Yelp than actually fixing the problem. I also want to respond directly to the statement that "this does not reflect the level of service we aim to provide." There's a difference between aiming to provide a level of service and actually delivering it. From my experience, that gap is exactly where the problem is. The bigger issue is their policies. They're structured in a way that protects the company, not the customer. So when something goes wrong, you're left paying out of pocket to fix their equipment while still dealing with high electric bills. That defeats the whole purpose of going solar. To be clear, this is not about the front-line staff. The people I've spoken with have been respectful and professional, and I understand they're working within the limits they're given. But as a customer, you shouldn't have to navigate policies that make it harder to get a fair resolution. At the end of the day, a response is not the same as a solution.

    We had our solar panels installed by SolarMax and our overall experience has been very positive…read more  From first contact to ongoing customer support, SolarMax has exceeded our expectations. We were fortunate to have Ruben G. as our Account Manager.  Ruben was professional, pleasant and knowledgeable -- carefully listening to my questions and concerns and also sharing knowledge so I could better understand the phases of installation. Throughout the entire process - from design to permits, documentation to electrical requirements, we communicated with the various SolarMax team members to make sure we understood what the next steps would be. Every team member was courteous and competent, all of them did their part to complete our solar panel and battery project. We are happy with the service and expertise SolarMax has provided us and would recommend them to friends who are considering solar energy.  To Ruben - our renewed thanks!  We appreciate you for your work. To the entire SolarMax team - thank you for making this happen!

    A warranty means nothing when the company fails to provide service…read more We made a substantial financial investment in a solar system that was sold with a warranty. Now that the system is not working properly, SolarMax says its service appointments are booked months out. When we explained that we could not continue waiting while paying high Edison bills, they suggested hiring an electrician at our own expense. Customers should not have to choose between waiting months for service and paying out of pocket to repair a system that is still under warranty. SolarMax should stand behind its product and provide timely service. Their service department has been extremely frustrating. We have repeatedly been promised return calls that never came, and some of the service representatives we have dealt with have been rude and dismissive. Meanwhile, our solar system remains down, and we continue paying for electricity every month. It also appears that service may be different depending on whether you purchase or lease your system. When a leased system stops producing, the solar company loses money and has a financial reason to repair it quickly. Once you purchase your system and the company has already been paid, it feels as though you are "put out to pasture" when service is needed. Also: READ THE FINE LINES: Before signing a contract, carefully read every detail and make sure every promise or guarantee is included in the signed agreement. Do not rely solely on assurances made through emails or conversations. Our experience has shown us that what is promised before the sale may not be honored afterward. We love having solar and are glad we installed it. We simply wish we had chosen a company that stood behind its product, honored its warranty, and responded quickly when its customers needed service. We lost our solar in the hottest months of 2026 and still don't see it being fixed any time soon.

Overall the team all seem to be doing their job and the execution is quick but the lack of customer communication is not up to par for a 50k project. It felt like I was the project manager all the time, following up on schedule, and then calling to verify. I had a feeling that the teams are split and everyone only does their job based on a scope and not as a team. Sometimes, I just want the truth on timing.... Bc Everytime I get a timing commitment, it's delayed and or no show and then also no updates. The project is still on-going with skirting, commissioning wasn't even done , painting of pipes/conduits... so will update accordingly. 8/6/26 : the team swiftly came the next day and finished painting and commissioning so I will add a star. 8/12/26: Just had a constructive discussion with Dayne and Savannah -- overall very positive. While my earlier frustrations were real, the conversation helped me better understand the complexities of the contractor side of the business. I also came away feeling that OC Solar genuinely puts care and attention into each project. The project isn't fully complete yet (inspections, skirting, and a few other items remain), but the overall execution moved at lightning speed and exceeded my own expectations. At the end of the day, it's the final result that counts so I will increase it to 5 stars.

    Project still in progress but so far so good…read more The quoting and onboarding process was great. Biggest hurdle so far was the HOA approval which is outside their control. I'll update this review later as the project progresses.
