The 4th year production shows improvement over the 3rd year as I kept the panels clean. However,…read moreit's still about 4.8% below the minimum guaranteed production (accounting 0.25% maximum annual panel degradation). It's 4 year in a row now the system failed to produce the minimum guaranteed production. AWS Solar chose to compensate for the shortfall again; we'll see what the 5th year production looks like. I suggested replacing some of the panels with the higher power ones to solve the issue, but I guess they want to see more data.

Within an hour of posting my initial review regarding a delayed referral bonus, the owner…read morepersonally reached out, apologized for the administrative oversight, and sent the $500 immediately. I really appreciate the direct accountability and quick resolution. I'm leaving my original review below for transparency, but their prompt response today restored my confidence in their management. I originally had a positive experience with California Solar Electric during my 10.12 kW solar and Powerwall 3 installation last year. Unfortunately, their post-install customer support and business ethics are nonexistent. I referred a friend who completed their installation months ago. I was explicitly promised a $500 referral bonus for this. After months of waiting, I tried following up multiple times privately to give them a chance to make it right, but I am now being completely ignored. It's a shame because I have several neighbors here in Fountain Valley who are currently shopping around for solar and battery storage. I was planning to refer them here, but I cannot recommend a company that fails to honor its own written agreements and ducks communication. Buyer beware: the installation team does good work, but do not trust a word management says about referral incentives or post-sale promises. Still waiting for my $500.

I'd highly recommend Solar Optimum and Roofing Optimum…read more We've had our solar system from Solar Optimum for more than 10 years, and our experience is a great example of why choosing the right company from the beginning matters. They installed a high-quality system that has performed extremely well over the years. At one point, both of our inverters experienced a manufacturer-related issue. In fact, Solar Optimum identified the problem before we even realized something was wrong. They worked directly with the manufacturer to secure a replacement inverter at no cost and handled the installation quickly and professionally. When it came time to replace our roof, we didn't hesitate to reach out to Solar Optimum again. Their GAF Master Elite certification and the advantages of having the same company manage both the solar and roofing work provided tremendous peace of mind. The warranty benefits are excellent, and the roofing warranty is transferable, which adds real value and is something many roofing companies do not offer. We recently completed a full solar removal, reroof, and solar reinstallation project with the Optimum team, and we couldn't be happier with the outcome. The entire project was completed in about a week, exactly in line with the schedule that was provided at the start. The crews showed up on time, worked hard, communicated well, and cleaned up thoroughly at the end of each day despite the significant amount of work involved. From start to finish, the process was smooth, professional, and well-managed. It's rare to find a company that delivers this level of service over a relationship spanning more than a decade. We couldn't be more pleased and highly recommend Solar Optimum and Roofing Optimum.

I went with Solar Optimum mainly because of reputation. I also wanted to go with a company that…read morewasn't going to disappear in the next few years. There were cheaper quotes for the system I wanted, but they didn't quite meet the aforementioned requirements (one, although competent, was way too new to feel comfortable with). Another competitor, probably the biggest one in Southern California, came out for a presentation, but their package was strictly a lease and didn't make much sense at all for me. The point of solar panels is to save money, and the projected money I would save was completely offset by the monthly payment. So, I decided to buy my panels outright, along with the Tesla Powerwall 3. It all was pretty pricey, but I will qualify for the federal rebate since the purchase was before the end of 2025. At least that's what I think. I was assured that I would qualify if I had a fully paid invoice before the end of 2025; although there was some other talk about showing proof of operation before the year ended. Solar Optimum couldn't provide me with a definitive answer, but my CPA said a fully paid invoice would work just fine. We'll see. The whole process began around 5 months ago. It started off with a rep coming out for a site inspection in order to put together a plan for me. That went pretty smoothly. Communication was primarily via email and phone. Their main office is on the Glendale/Burbank border. I went a couple of times to drop correspondence off. Once they put the plan together and I signed off on it, the physical installation came a few months later. That took only a day and it looked pretty clean and professional. The next stage was for Edison, my electricity provider, to come out and install the adapter. But that took a couple of months for them to even get here, and when they did, it turned out they couldn't install it at all because the adapter was damaged. The installers had placed it in a bag, but didn't secure it properly. Unfortunately, water from the autumn rains got into the bag and damaged it. So, it took almost another month to replace the adapter and have another Edison tech come out to inspect and install it. The last step is to have the city come out to give a final inspection and to give the permit to operate. As of today, late December, the inspection has yet to be done and the solar panels are just sitting there, inoperable. I understand there was a lot of orders for solar as people were rushing to get their purchases in before the 2025 federal rebates ended. But it's been 5 months and I've already fully paid for a solar panel system that hasn't been even been turned on yet. I don't really blame Solar Optimum since I'm really on Edison's and the city's time, but it is frustrating having to wait so long. Once it is turned on, I'll update this review.

A few months ago, we decided to move forward with installing a 13.4 KW solar system. Imperial Solar was fair and transparent during the evaluation, and efficient and detail-oriented throughout the installation. The crew arrived on time and left the area clean. The system was installed professionally and looks excellent. Since our meter change, our bill has decreased by 80%, even during winter. We look forward to seeing our savings in the summer. We are very satisfied with Imperial Solar and highly recommend them to anyone considering a solar installation.

They do a lot via text, which I liked, but it turned out not at all useful. I would text for updates, and hear nothing back. I would call to find out my contact was out of the office, on vacation, or any number of excuses. This went on for many weeks. I did not know the date for installation until a delivery of equipment showed up at my house unannounced. It was a good thing I happened to be home that day! I thought the installation itself had gone well. They installed the system in two days and everything looked great. Then, I had to wait for the meter collar to be installed. I was told it was going to be performed by their technician. Turns out it has to be done by SCE and that had not been scheduled. After I called again, SCE was finally notified. SCE arrived several days later to discover the cables were too short to install the meter. Now I have wait again for OC solar to come out again and fix this issue and wait again for SCE to finally install the meter so that I can use my new system. I hope the system works.
