    Desert House of the Moon
    Christopher P.

    Without Vic's tireless commitment to our project this home would not have been possible. This custom house in its off-grid configuration has not only made the project possible, but has led to more work for my firm by attracting the interest of a progressive, sophisticated clientele. I can not say enough of Vic's years of experience in the field, and how his commitment to the job inspires the solar contractors he works with to take advantage of the latest technology & equipment available. I look forward to working with him again. Christopher Payne, AIA, LEED AP Architect

    Everything working seamlessly. Thank you Vic.

Best warranty and quality materials and labor. 949 637-9108. They are out of Santa Clarita. We are so happy and satisfied with our system and our bills have gone from $300 plus a month to less than $40 a month. Also when the power has gone out in our neighborhood the battery backup has saved the day. Stellar value, workmanship, professionalism and service plus a 25 year warranty. Highly recommended

Their quote, plus their high reviews made them the logical choice, and we have no regrets. From the person who did the site inspection, Jose, to the installers, everyone seemed very friendly, respectful of our property/wishes, and it was clear they were experienced and knew what they were doing. Being up against a deadline, we really couldn't afford to fail the city inspection, and we passed easily. Thanks to the salesman Mark Howe for his direction, & to Henry Melling for a great design and implementation. We were not excited at the idea of having all that stuff on the side of our house, but honestly, the installation was so neatly done, with a few plants added over there, I'm sure we can acclimate. The battery placement in the garage was genius -- up and out of our way! Everything is functioning as it should, and we wouldn't hesitate to recommend California Solar & Electric. THANKS to them for a job well done, and ON TIME!! We couldn't be happier.

    This company installed our solar panels two years ago. We have a steep roof so it was a unique…read morechallenge. When we initially met with Joy she represented that they have experience designing solar for steep roofs and she showed up examples of prior work. During the design, contracting, and installation phases, the company was responsive and easy to work with. However, one year later it became clear that the design was not sufficient to meet our solar needs as Joy and Han represented; not even close, and we are still paying a large electricity bill each month. As such, the economic analysis offered by the company to entice us to move forward with them doesn't pencil out and we might never recover our investment costs. If they had provided the actual solar production, we would not have moved forward with the project. When we contacted the company about this issue in summer 2024, they were very slow to respond and even though they offered to redesign the system, they delayed and delayed and often we had to contact them multiple times before we received a response. Further, they tried to shift some blame to the "trees and unexpected weather conditions." The trees being referenced were there at the time of their bid and appeared in their modeling. The trees are trimmed regularly. The weather has not had any significant deviations. More than a year after we contacted them, they have not yet redesigned the system, nor can they guarantee that the new redesign will cover our solar needs. It is very disappointing that they have not made this right. Hopefully, we can still resolve this issue, but I felt compelled to write this review so others are aware that the anticipated solar production and the economic analysis to convince you to sign may be grossly misleading.

    Joy and Hans were great, and super helpful along the way. Our system was beautifully installed, and…read morecustomized to the needs of our property. They helped us sort through lots of options and configurations. Prices were competitive with bigger 'name' companies. We really prefer using local companies, especially with something like solar, where having them nearby is a benefit. I would highly recommend you talk to Altadena Energy & Solar over one of the bigger national companies.

    Update for my review with OC - Savannah from customer service reached out regarding my experience…read moreand expressed regret over how things went and changes were actively happening at the company. She offered a free panel cleaning, which she set up internally and had their team come out this past Friday without issue. Since the cleaning the panels have been much better performing especially after these past few weeks of misting and rain, about 25% higher output. I didn't think much of it but I get now it's worth doing to get the most out of the panels. Overall a very good response and experience with OC specifically for this issue. I feel that they do want to stand out from the crowd and responding proactively to feedback gives me more confidence they'll take care of issues as they hear about them.

Every person who came out was professional and respectful. What really set them apart was handling both our full roof replacement and solar installation together. I didn't want a roofing company and solar company pointing fingers at each other down the road -- OC Solar eliminates that headache entirely. Their pricing was competitive, and their substantial warranty sealed the deal. Highly recommend them if you're considering solar!

They were professional, clean, cordial, and the end result was exceptional. I am very pleased with the work performed and everyone that was involved. I hope highly recommend them especially since it's so hard to find a company that will still be around in years to come. My worry was that the installation may contribute to future leaks due to rain. I observed the installation process asking questions and am satisfied that I won't have any issues.

Because of that experience, we were very cautious when we decided to add more panels and reached out to several different companies. From the very beginning, HPM Solar stood out. They were easy to work with, communicated clearly, and consistently kept me informed about every step of the process. There were no surprises and no guessing about what was happening next. We were also extremely fortunate that an earlier installation slot opened up, allowing HPM to fit us in just in time to take advantage of the expiring tax credit -- something we truly appreciated. The installation crew was excellent: professional, efficient, and respectful of our property. They did great work and made sure everything was cleaned up before they left, which really showed their attention to detail and pride in their work. Overall, the entire solar process with HPM Solar was very smooth and stress-free, a complete contrast to our previous experience. I would absolutely recommend them to anyone considering solar.

    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 contacted Solar Optimum for a home backup battery installation using an Enphase 10C battery. They…read moreinitially quoted me $10,146.50 for the project. Before conducting a site inspection, they required me to sign a contract and pay a $500 deposit. After completing the site plan, they informed me that a panel upgrade was necessary and that the battery would need to be installed in an inconvenient location. These changes increased the project cost by an additional $3,700, bringing the total well above the original quote. I was surprised by such a significant price increase and decided to cancel the project. I then requested a refund of my $500 deposit. It took nearly two months and more than ten phone calls before I finally received an answer. At that point, I was told that the deposit was nonrefundable because I had signed the contract. I find it unreasonable that Solar Optimum required a signed contract and deposit before conducting a proper site assessment, then substantially increased the price afterward and refused to refund the deposit when I chose not to proceed. In my view, a thorough site inspection should have been completed before providing a quote and requiring a commitment from the customer. Based on my experience, I would advise potential customers to carefully review the contract terms and understand the refund policy before signing.
