    Some of our many solar panels.

    Solar Harmonics implemented our new Solar Edge solar system and we are now free from the bounds of the evil PG&E! Jamie Duran was extremely easy to work with, answered all of my many questions, and their crew did an excellent job in the implementation. We requested some significant last minute changes to our requirements and the Solar Harmonics team handled this with professionalism and efficiency. We are extremely satisfied with the entire experience and would highly recommend this company to anyone.

    Jamie Duran at Solar Harmonics is an exemplary professional in the solar industry. Their commitment to delivering top-notch service is commendable, ensuring a seamless experience for our recent solar installation. My site visit/installation and inspections scheduled quickly. The whole process was done in weeks. highly recommend solar Harmonics for their expertise and dedication to customer satisfaction.

    Strong recommend! I worked with Jaime on a single-family home solar job and would highly recommend Jaime and Solar Harmonics. Low key, yet deeply experienced. No pressure, yet ready to spring into action when the customer is ready. I came to know this company through Yelp reviews and want to post one so others can have a similar positive experience. Definitely give this company call if you're considering solar.

    Solar Electric Panel Installation Photo 1

    In 2022 after a long hot summer here in Brentwood, Ca and off the chart electric bills, my wife and I decided it was time to consider Solar for our 3600 sq/ft home. We spoke with a number of Solar Electric Contractors in the pass but could not move forward due to lack of confidence and poor reviews. When we were ready to move forward in 2022, we interviewed three local companies. At the end of the day we selected Solar Harmonics. Jamie was friendly and knowledgeable and in my opinion, cared more about educating homeowners then just making the sale. Jamie stated that the project from start to finish ( City Permits, equipment ordering, installation and final inspections) could take 60 - 90-days to complete. We were working on a very tight time-line and needed this project completed before the end of December 2022 to get the Tax Credit in 2023. On top of all that, we had to deal with the rain! Jamie and his team came through. The installation was completed in 1.5 - days and the project was signed off by The City of Brentwood Inspection Dept. and PG&E in under 2-weeks. Record Time ! The system is on-line and appears to be working find. The installation is also very professional. Out of all the installations I've seen in my area, Solar Harmonics is the only company that paints the conduit on the side of the house. Nice Touch ! I worked as an IBEW electrician for 23-years and I am currently consulting in the commercial market so I am a little "OCD" in regards to workmanship. Highly recommend Solar Harmonics.

    14 Silfab panels installed. Even attached some preventative netting around the edges to keep debris and animals out.

    I worked with Jamie to have solar panels installed on my home in San Mateo. I had a great chat with him and he communicated every step of the way. There wasn't a long chain of project managers or sales people in between which was great. Once the permit was approved, installation and activation happened lighting fast. I also listened to his podcast which helped me get more familiar with the industry around NEM 2.0, tax credits, batteries, etc. His quote was better than larger companies that have a lot of overhead and used the exact same panels and inverter. Very happy I went with Solar Harmonics.

    We decided to find out about purchasing a solar system, Solar Harmonics was recommended, we contacted Jamie at Solar Harmonics.  After speaking to Jamie for 15 minutes, he understood what we were looking for, and started an estimate for our project; the literature he provided recommended we get three estimates, which we did. After comparing service, warranties, and pricing, Solar Harmonics was the choice.  Jamie stayed in contact throughout the process of design, permits and installation.  His operations manager Jared that handled the actual install was professional and provided workers on site that were efficient, professional, polite, and respectful while working in our home. The project was started and completed on time with great communication and care.  The system is working fantastic, and delivered as promised, We would recommend using Solar Harmonics.

    That's 30 panels up there!!!

    Jamie was terrific through the whole process and we could not be happier! Our system is efficient and looks so streamline on our roof (away from the front so it's also not an eyesore!) good pricing and reliable which is hard to find these days. Thank you Jamie and Solar Harmonics.

    This graph shows the power generated by my system since it was installed.

    Fifth year update: I'm still thrilled with my solar system and still thrilled with Jamie. I'm in the process of buying a new house, and I contacted Jamie to find out if Solar Harmonics covered my new neighborhood (he did). Jamie also let me know that he'd help me get my warranty and monitoring moved over to the buyers of my existing home when the time comes. Bottom line? I'll be using Solar Harmonics to put a solar system on my new house, and I'm thrilled that I can be a repeat customer.

    Only 8 of the 35 panels we installed!

    Had such an excellent experience with Jamie and team. Straight forward, approachable and ultimately a non-stressful engagement. We installed a 35 panel / 11kwh system (should have gone bigger!) with Solar Harmonics and comparative to the Energy Sage quotes and searching around with other providers we ultimately chose Solar Harmonics because they've been around so very long! To be clear I did an exhaustive search and price comparison of 16 different options/vendors in 2017. When I finally moved forward with this project in 2021 I found that quite a few of the installers were no longer around or available. The fact that SH has been around and has a very excellent track record gave me confidence in working with them. Would totally recommend them for future projects and my (likely) solar expansion!

    I was contemplating to install solar 2-3 years ago. I received multiple quotes and came across Jamie with Solar Harmonics. I looked through the reviews here and i decided i would go with Jamie. However, I actually ended up doing something else instead of investing on solar. Fast forward to this year, i reached out to him again and good thing he still remembers me and we hit the ground up. Everything went smooth, system looks solid. The team showed me how things work through mySolarEdge app. I am really happy with the system and i am really glad i waited and chose SH. It took a while to get approval from the city but Jamie assures me everything would go through and it did. Thanks team for all the hard work and getting this system up and running.

    Conduit matches the trim to blend in like it wasn't there
    Victor G.

    We chose Solar Harmonics as our installer due to their astonishing Diamond Certified Rating. David was very knowledgeable and straightforward in explaining the pros and cons of having solar at this time due to future electricity rate hikes we are expected to get by the end of the year. We want to take advantage to lock in on current rates than pay the future rates in kwh. Solar Harmonics install team did an incredible job installing the 19 solar panels at 300w rating. We also installed an Ev plug connection in our garage. They matched the paint color on the conduit to our trim color so it blends in so well we couldn't tell there was an installed conduit. I would recommend Solar Harmonics again and again. We tooked less than 4 weeks to plan, install, and connect to the grid to start saving money on electricity. Thank you David , Amanda, and Jamie for making this all happen.

    I must say working with Solar Harmonics was an absolute joy. Jamie came out to tell us about his company and to give us a quote on the job. This was a no pressure sales appointment!!! He was very honest when we asked him if we needed a whole house fan and battery pack. He said no to both. This could have added a couple of thousand dollars more to the job and we would have not known any different. When it was time to install the panels, his guys were on time, very respectful, and cleaned up after themselves. I was surprised it took them only five hours for the installation. I would most definitely recommend this company for your solar needs. I've already referred three families, and will continue to do so! Thank you Jamie! Lar

    We contacted Solar Harmonics again, after purchasing a system 5 1/2 years earlier from them because we needed a little more panels. I dealt directly with Jamie (owner) through email from start to finish. He was so patient with me, answering any questions, providing details about panels, pricing, set up, basically everything! I literally emailed him 31 times (no lie) and each time he responded, with knowledge, answers, and never treated me like a pest. From start to finish, the entire process was smooth. Everyone who came to work at the house was professional and knew what they were doing. I would recommend this company when looking for solar and am looking forward to all the more energy being produced at our home!

We were interested in solar for our 1940s home and provided a deposit in good faith. However, after further inspection of our roof and the overall project viability, we decided not to move forward. When we requested our deposit back--before any equipment was ordered or installation began--the company initially refused, claiming it was 'passed' the point of a refund. It was a high-pressure situation where we felt they were trying to lock us into a contract we weren't comfortable with. While we did eventually receive our deposit back after pushing the issue, the initial refusal to return funds for work not performed was a major red flag. Homeowners should be very careful with the fine print here. If you are looking for a company that values transparency and customer comfort over just 'closing the deal,' I would suggest looking elsewhere. We're glad we didn't get stuck with them and are instead putting that money into improvements that actually fit our home.

    I can't say enough good things about Carlos Gomez from Sunlight Electri-Cal Solutions…read more I've been working on a non-standard solar setup using an EcoFlow Delta Pro Ultra X and EcoFlow Smart Home Panel 3, and finding a contractor who truly understood this type of system was incredibly difficult. I spoke with many contractors, and almost all of them sent salespeople who gave generic answers or tried to push cookie-cutter solutions that clearly didn't fit my setup. Carlos was completely different. From the moment he arrived, it was clear he wasn't a salesperson -- he's an engineer, and it shows. He took the time to deeply understand my system, reviewed actual spec sheets on the spot, and immediately identified issues that other contractors completely missed. Multiple companies told me Hyundai panels would work fine. Carlos checked the amperage limits, applied proper safety margin calculations, and clearly explained why those panels would not work with my EcoFlow system -- saving me from a costly mistake. He also walked me through: Proper panel selection within voltage and amperage limits Safe string configurations and series wiring How to maximize roof space while staying within code Permitting requirements I hadn't been told about before On top of that, Carlos identified critical code and safety requirements that no one else mentioned: Bollards required in the garage to protect battery units Correct battery placement to maintain required clearance from doors and entrances Heat detector requirements for battery installations in a garage These are all things that would have caused inspection failures later -- and Carlos caught them immediately. He spent well over an hour with me, climbed onto my roof to check for obstructions, inspected battery placement, reviewed wiring paths, and answered every question in detail without ever rushing me. What truly sealed the deal was how efficient and transparent the pricing process was. Carlos was able to turn around a detailed quote very quickly, and when I received it, I was honestly surprised -- it was a significant amount lower than every other quote I received, even though his evaluation was by far the most thorough. Given everything: His technical expertise The level of detail and care The ability to integrate with my existing system The fast turnaround And the much better pricing Choosing Sunlight Electri-Cal Solutions was a complete no-brainer. Carlos is knowledgeable, meticulous, honest, and genuinely passionate about doing things the right way. After meeting him, I completely understand why this company has such strong Yelp reviews. If you're in the Bay Area and need electrical or solar work done the right way, especially for a non-standard or custom system, I highly recommend Carlos and the team at Sunlight Electri-Cal Solutions.

Juan was very responsive and came out to take a look at our home right away. What I loved about Juan and his team is they are NOT sales people, they're real engineers who are focused on solving your problems and meeting your needs. Juan and his team are true solar experts and know exactly what they are doing - they were great at walking me through key details I should know about the system, how to best take advantage of having a solar system, and did their best to get me scheduled (in spite of multiple difficulties) for installation before the end of the year. Just for context, I've talked to another solar company where clearly they were just about trying to close the deal and sell sell sell, which really turned me off - it felt like they just wanted our money as opposed to wanting to understand what we really needed. Juan's team really shined here by just showing up to be real experts who are thoughtful about what system you need, as opposed to trying to close a deal. Juan and his team were also really patient and flexible. Our new home's solar system had to be turned on before we could start any work, and that process took months due to Sunnova going bankrupt. And, they were also really thoughtful when we mentioned we had added in some upgrades that would affect electricity use (ie saunas and outdoor electric heaters), and they reassessed their initial project and updated it to accommodate that. I thoroughly enjoyed working with them and am really grateful that we got our project done so well!!

We got a recommendation for Del Sol from one of our friends that was happy with their process and service. We reached out to Elvin and he was able to send us over a proposal very quickly based on whatever tool they used to see our roof. He provided two options for our roof, a 19 panel configuration and a 21 panel configuration. We decided to go with the 21 panel configuration for our roof and it estimated putting us at 98% of total output. After looking at the cost of the system, we didn't think we would be able to get it for a couple of years, but Del Sol offers multiple financing options. We decided to use the local credit union for financing. After we decided on the configuration and got the financing locked down, the turnaround time was approximately three weeks. Which was a whole lot faster than we would have anticipated. Installation took a total of two days with the city inspector coming out the second day. After the installation, paperwork has to be submitted to PG&E to be turned on, which took about 10 more days. Bird proofing for our panels was part of the package and it was done a few days after the final install. Our Conclusion: So we've had our panels for about four months and are extremely happy with them. The process went extremely fast. Supporting local reputable companies are very important to the wife and I, for us it definitely felt like the process was very streamlined to the point of being overwhelming. Using reputable local companies for our home improvements has definitely paid off in spades. Del Sol already installed panels in our neighborhood and knew exactly what our HOA required. The permits were pulled in a timely manner, and inspection was scheduled and concluded on the final day of the install. The major hiccup we had was we wanted to get our roof. Inspected prior to the install. The installation team was very professional, and courteous to us during the install and checked in with us every day with what to expect for that day. The final solar manual was delivered by Elvin and he went over everything in it, which also included the app used to track the performance of your system. Everything was laid out and explained as far as all the warranty information and what to do when the county sent you that "home-improvement" letter. I shared our whole story for people that are just looking into getting solar and wanted to know what they might expect. If you're a Brentwood local, and you decide to go with Del Sol, you won't be disappointed. The quote was very comparable to all the others we received. Elvin's service and knowledge was outstanding and the installers were professional and efficient. Also being able to use a local credit Union for financing was an additional plus for us. Yes, I would recommend them for your solar system needs.
