They suggest regular cleaning will help keep performance on track. I am still skeptical, but I will do this and keep track of the system production monthly to see whether or not it's going to meet the guaranteed minimum production. I truly hope my solar system would performed as they claimed; I would be happy just to get the guaranteed minimum production. I updated my rating back to 5 Stars based on their cooperation in addressing the issues reasonably fair.

California Solar and Electric was great to work with. But I wanted to provide a more detailed…read morereview than I normally do as this was a bit more complicated than just going out to dinner. At my old home I had solar installed without any kind of battery backup as at the time battery backup was really not an option. Solar was pretty good but did not provide me with a zero bill. When I sold that home and moved into my new home the cost was more than I wanted to spend. Fast forward three years and prices have come down and with the federal tax credit expiring I decided to make the investment as the cost of electricity seems to keep going up. I wanted to go with Tesla as being a big company I thought they would be a good choice. The first problem I had with them is you can't reach a person to talk to. And for the amount of money this costs I was not really comfortable, however I moved on and paid a deposit and started the process in September of 2025. When I finally was able to speak with a person they told me that they could not guarantee that they could complete the installation by the December 31, 2025 deadline, really 4 months of lead time? I canceled Tesla and looked around at my other options. Shelter came to my home and we spoke. They were knowledgeable and the salesperson was really nice, however their price was a huge difference from the other two quotes that I received. Quantium was another company that I spoke with, and I was ready to use them as they were much bigger than California Solar and I thought that might be a better option, plus a neighbor had used them and were happy with them. However when I got the contract from them it basically stated that they wanted a $1000 deposit and if they found that I needed additional work and if I did not want to continue then I would loose my deposit, that seemed outrageous so I told them that I would not continue with them. Note that after I had decided to go with California Solar and Electric they told me they would give me the deposit back if that would happen, but by them I had already signed the contract with California Solar and Electric and honestly was happier with them at that point. I spoke to Mark Howe and he was excellent. I told him about Quantium and he sent me a copy of their contract and told me that they did not do that. His price was the same and the equipment was the similar. Note that they actually had to upgrade my solar panels and did not charge me any additional fees. They also did some additional work to allow more of my home to be backed up than their original quote. Mark told me that he could get the job done before the tax deadline so I signed with them. The process took a bit of time as we had to get permits and approval from the HOA. But the system was installed on time and fully completed well before the deadline. They actually worked on the installation during huge winds and rain. It did take a day or two longer to complete than what they originally thought. One of my batteries was bad out of the box and that created a bit of an issue but Henry was amazing and took care of everything quickly and professionally. He was even nice when I messed up and scanned a QR code that I thought would download a different app but it basically erased my home from my app. Note to self, double check before scanning QR codes. All in all the process was professional and was handled as quickly as possible. Communication was good even though they were swamped trying to get everyone installed before the end of the year (2025). Everyone that I dealt with was really nice and easy to work with. I think I must have driven Bella their wonderful assistant, crazy calling so often. Of course Henry had to deal with all of my questions which he handled and made me feel very comfortable. I would suggest that if you do decide to go solar, give California Solar and Electric a call and get a quote. Thanks for reading my lengthy review.

TL;DR: Rose is incredible. Honest, patient, actually knows solar and is not just a salesperson. She…read morewill answer every single question you may have and follows up. Has a professional installation crew and executes flawlessly and everything stays on track. Incredible follow-up and will not try to upsell you like other installers. If you're looking to install solar, you should absolutely go with OneSun. Give Rose a call to at least get a consultation and I'm sure your interaction will immediately stand out from other installers. Installing solar is something I kept putting off. When I found out that the tax credit would be going away at the end of 2025, I realized I couldn't put it off any longer. One of the reasons I kept waiting was how annoying solar reps were. Clearly just sales guys who didn't actually know anything about the equipment, technology, and process. I did a bit of research on local installers and OneSun came up a few times, all with nothing but great things to say and especially highlighted the installer's knowledge and patience. Before reaching out to OneSun, I informed myself as much as I could to the point that I knew what panels I wanted, size system, even what inverters I wanted installed. My first phone call with Rose immediately proved that all of the positive feedback I had read was for a reason. She took the time to actually listen to the specifics of my project, what I was looking for, and what questions I still had based on my research. She took the time to answer every question and even went into the technical details that I was interested in. It was clear that she was extremely familiar with not just the logistics, but also exactly how a solar system works as well as the technical details of all of the components in a system. She had my business after that first meeting but of course I still did my due diligence and got a quote from one other local installer which also had similar reviews. Although the sales rep was very nice, it was clear that he was just a sales rep and only reinforced why OneSun was the installer to go with. OneSun's pricing happened to be better but even if the other installer would have come in at a cheaper quote, I would have still chosen OneSun for the install. Rose started the permit process in July and made sure that everything stayed on track, especially since I wanted to make sure that the system be on before the end of the year in order to qualify for the tax credit. The timelines she provided were right on point and the install was scheduled for September. About a week before the install date, there was an unexpected problem. The panels that were originally planned for my install had gone completely out of stock. There had been some kind of manufacturing issue and those panel would not be coming back in stock for another couple of months which could push the project out to the following year. Rose let me know she could acquire slightly larger panels for the project and install it on schedule. I was about to ask what the additional cost for the larger panels would be, but before I was able to, she let me know that there would be no additional cost to me. I'm sure any other installer would have used the situation as leverage to add additional cost to the project. A testament to Rose's commitment to her customers. On installation day, the crew was professional and efficient. They completed everything in one day and made sure to keep everything as clean and organized as possible. Towards the end of the install, I had noticed that they ran one of the grounding wires out from the attic and down the face of the house where I had planned on completing another project in the near future. I knew that the wire would need to be redirected if it was left there so I asked the foreman if he could run it through a different path. Initially he felt like it would not be possible given the layout. I reached out to Rose just to make sure and see if she possibly had another solution. About 10 minutes later the foreman showed me another possible option which was much better for what I needed. It may have seemed like a small thing, but that was another instance in which I believe any other installer would have dismissed my request as pickiness and told me there was nothing else they could do. Rose took the time to speak with her foreman and truly assessed the situation to come up with a solution that fit my needs. It took LADWP about 6 weeks to get my meter installed and for my system to be turned on, but it was still well before the end of the year (and yes, I just got my tax refund with that hefty solar tax credit). It's rare to come across someone like Rose who is honest, patient, and who truly has her customer's best interest at heart. Combine that with impeccable execution and communication, and there is no one else I would recommend for a solar install project. In fact, my parents are considering a small project and I've already told them about Rose/OneSun.

When I first contemplated getting solar panels for our house, the entire process looked daunting. I…read moredidn't know anything about the technology or equipment and I felt ill prepared to make any decisions about what our house needed. There are so many companies out there, it's hard to know who to trust. As soon as I did a few online searches, I was flooded with emails and texts from multiple companies with high pressure sales pitches. One company charged me $350 to do a site survey, just to get a quote for the project, then came back with a revised quote adding $7000 to dig a trench for electrical wiring due to "the location" of our electrical panel. I found OneSun on a yelp search and as soon as I spoke with Rose Avakian, I knew my search was over. This company stands out from the others. There was no sales pitch, pressure, or upsell. Rose explained the technology and equipment in a way that made it understandable and approachable. When her team came to look at our place, they found no need to dig a trench and simply connected to our existing electrical panel. Had they needed to dig a trench, the price they quoted was nowhere near $7000.  From start to finish, the entire experience was transparent, seamless, professional and expedient. The attention to detail and care the team put into making sure everything was done right far exceeded my expectations. If you're looking to go solar, look no further than Rose and OneSun. This is truly the best company I've ever worked with!

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.

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.

This update relates to my previous 5-star review…read more Approximately a year after DLS Development finished the complete re-roofing of my house, I discovered that the roof guards/drip edges near my main door threshold and in several other spots were accidentally missed during the installation. I only pinpointed the problem recently (last quarter) when I noticed the area approaching our main door in the mornings following humid nights. Knowing how much time had passed, I fully expected DLS might dismiss my concern. To my amazement, DLS crew promptly arrived and fixed the oversight around my home at no cost. This proves DLS is more than just a company that performs an excellent re-roofing job; they are incredibly responsive and stand by their work - even for seemingly small issues that arise long after the initial project is complete.

We took a couple of months to meet up with other roof companies for quotes and ultimately hired DLS…read moreDevelopment. Spencer from DLS Development gave a great pitch, plus the quote was one of the lowest we received from almost all roofing companies. They reached out over a month later to check in and offer an additional discount. Pros: The workers did an excellent job and worked from nearly sunup to sundown. They had a few questions, which I could answer (or get my husband to answer) when I was around. It took about 4 days for them to tear off the old shingles and install the new ones. And it was hot out there! They did the work quickly, professionally, and efficiently! One of the crew members performed a walk-through with my husband once they finished, and my husband was very pleased with the finished product. I feel very grateful looking at my roof now, since the old one was very old. Cons Once we signed the contract and paid the initial deposit, we were told that the permit for our house needed to be pulled and that it would take about a week. Almost two weeks later, I asked the project manager if she had pulled the permit and when the project could begin. She then let me know the roofers would begin the following week. I guess I hoped that the project manager would have reached out to me first to let me know that the permit situation was complete and that they would begin the roofing process. You need to take initiative and find out what's happening, since I've never had a roof replaced before. Next, the project manager informed us they discovered and replaced rotted wood. The project manager sent us a change order for the additional amount, yet the contract did not list any extra charge for rotted wood. Additionally, they had already replaced the "rotted wood" before we signed anything, and they had no clear photos showing any rotted wood. It took a lot of emails and texts back and forth before we reached a resolution we were happy with. Still, it was a headache and frustrating for several days; we had to deal with uncertainty and explanations. Finally, the project manager never confirmed when the inspector for the last inspection would actually come to our house to collect my signature on a form. We didn't know whether we needed to be at home, leave the document out somewhere, or when the process would officially end. I received an email from the project manager asking me to reply and attach the form with my signature, as the inspector had come around but could not collect it because I was not there. I replied to the email with the form and asked the project manager if I needed to do anything else. Only when I reached out again to the general DLS development general email was I told what day the inspector would come around again to collect the form. We're thrilled with the roof and the quality of work, but it would've been less of a headache to have a lot of this information up front without having to keep asking, since I'm unfamiliar with the roof process. I also had to email the general DLS development email, as the project manager was not responding to some questions and concerns as quickly as I would've liked. I know she probably had a million things going on, but it felt like I got a response much quicker once I emailed through the general company email. This was not a cheap project, and I feel like this company lacks clear communication, but their workers and work are absolutely outstanding.

I was stuck in a very unique and tricky scenario in which our power was shut off by LADBS…read more The requirements to restore the power were extremely particular and hard to decipher. It required inspections by multiple agencies, with hazy details on what they wanted done. I spoke with many electricians during this time; none of which had any desire or willingness to assist. I had guys trying to hustle me and quote work that was way outside of the specifications for the job. That's when I decided to call QM Electrical Services. Upon the first time speaking with Marvin, it was clear that I was speaking to a professional and a straight shooter (a rarity in today's service industry). Marvin was more than happy to assist with the job with a very reasonable fee associated with the work. He spent countless hours on the phone and internet submitting forms and speaking with the representatives from both agencies. He made all upgrades and corrections as requested. He was available at a moment's notice and on-site whenever there was an inspection scheduled. Eventually, after jumping through a million hoops, he was able to attain approval from both agencies and our power service was restored after over 2 months!! We could not be any more grateful that we found Marvin. We would probably still be sitting here without power if it weren't for his dedication and efforts. It goes without saying that I recommend QM Electrical for any and all electrical projects (including solar). Marvin is an honest, hard-working, and dependable guy and you can trust that you will be satisfied with his services!!
