    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.

    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.

George showed up at 1:30pm & switched out the old inverter for the new one. Everything is working great like it used to! Ivan, Scott & Jayson have been in constant contact with me about the progress of getting Tesla to ok the work. So grateful for their dedication! I definitely recommend Option One Solar! Update. To be clear I have nothing negative to say about Option One Solar, at the time I was disappointed with the outcome that seemed that I was out of luck. 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.

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!

    I wanted to share my recent wonderful experience with my recent service visit with Infinity Solar…read more I purchased my system in 2024 (detailed review also done); during this time, my solar generation has been absolutely wonderful, and sized perfectly by Kay. My electric bill is essentially free over all of 2025 and this year. Some months have a $10 dollar bill, other months negative depending on how sunny each day is. I have had zero issues whatsoever and system works like clockwork. The installation over my tile roof, done through Terrazas roofing, partnered with Solar has also been top notch with zero issues with multiple major storms last year. I would say i was 110% satisfied with my decision to go solar and with Infinity solar. Fast forward to 2026. A series of recent power outages resulted in no power in my home. My initial thinking was that my system should have generated power with a fully charged battery during this outage. After calling Infinity, it was relayed that my system per contract was only set up for load shifting by design, lowering cost which I had decided on. After discussing 2 options to allow for backup power generation, i decided to proceed with the upgrade. Throughout the process, the entire team supported me exceptionally, starting with Sara who stepped in to help speak to me when the service department was not available at the time. As i did'nt understand my contract fully,, i reached out to Kay in sales, whom i did not speak to in 2 years, who really went above and beyond to explain to me in full detail how my system was set up, and options i had to upgrade. Kay treated me like family. I was so appreciative of her kind approach. She helped coordinate a technical call with Joel to fully answer all my technical questions. Once i decided i was comfortable with to proceed with the upgrade, the service team took over, with Vanessa and Brianna helping me schedule my service. Vanessa and Brianna work tremendously well together; super friendly, pleasant, professional and helpful. I requested looking into a couple options which Vanessa followed up on and accommodated without hesitation. A straight forward and exact quote was provided on Thursday. Their service and help was fantastic and greatly appreciated. Upon approving my quote on Thursday, my service was completed on the following Tuesday, much faster than I expected. Upgrade was performed by Ivan, electrician specialist. Ivan also initially setup my system in 2024. His expertise is perhaps, in my view, the finest in the industry. I felt very fortunate and appreciative knowing i hd my system in the best hands. He spent about 3 hours working on my system, explaining all the steps. Work performed was tremendous. Ivan patiently answering all my questions on some of the system parameters forgotten over the past 2 years. System was up and running and verified to work fully with a simulated power outage performed through the fuse box, and through the app. I was thrilled to now have backup power during outages. Billing and final payment was as quoted and super easy. In closing, the real mark of any business is how you are treated after the job is complete. My belief is that Infinity solar lives up to their reputation of being an exceptional 5 star company providing high expertise solar services through all phases of a project; sales, installation, commission, operational life, and post installation services. In a business of fraught with fly by night companies, Infinity Solar is a true gem. Solar done right with integrity, highest expertise, and exceptional, prompt service when called on. Thanks again to the entire Infinity team. 5 Star once again! Dave C
