    Solar panels

    Cori is the rock star of solar systems! We reached to Paragon Sun in summer 2024 to replace some of our existing solar equipment and to install a battery system. Cori was extremely responsive and helpful. She is super knowledgeable and able to help us figure out exactly what we needed. Her expertise isn't just in the equipment itself, but she is amazing at navigating through the whole process. Our process was more challenging than most because the applicable federal energy credit was expiring at the end of 2025, so the manufacturers and SCE were backlogged. But Core navigated through it all and got us up and running by the end of 2025, and made it look easy in the process. Cori's team was delightful to work with. Victor was our day-to-day installer on site, and he was excellent and really pleasant to work with. Our refreshed system has been up and running now for a couple months, and everything is working fantastic. We use a LOT of electricity, but we are now pulling very little from the grid. The Enphase batteries do a great job ensuring that we are never buying power from SCE during the expensive periods, and our solar is sufficient that we draw very little from the grid even during the non-expensive periods. The system is giving us a great return on our investment. I also hate SCE, so it's enjoyable knowing that I'm giving them as little money as possible. I would much rather pay Cori than SCE, and her electricity is much cheaper! One fun nerdy story: A week or so ago, the National Weather Service we had a severe winds alert in the middle of the night. Our system automatically noticed the alert, immediately charged our batteries to 100%, and sent me an e-mail notification that it was charged and ready in case the winds resulted in a power outage. This is a feature you can turn on or off, but I love it! It's fun that, even if the power goes out, I won't know it except for the FYI e-mail that the Enphase system sends me to let me know my batteries have me covered. We have power outages a couple times a year in my area, and it used to be super inconvenient. We rely on power for our internet, and we are cord-cutters so the internet is our TV provider. I'm retired, and all my hobbies require power. I also have a fairly elaborate home network, and it is a bit of a hassle to reboot my servers and get everything running smoothly after an outage. I love the fact that I don't have to worry about any of that any more. If you are considering a system, definitely choose Cori and the Paragon Sun team. It's not possible to provide better service than they do.

    System 1 - 32 solar panels, 3 batteries, installed Dec. 2022 Addition to System 1 - 1 battery installed March 2023 System 2 - 16 solar panels, 3 batteries, installed May 2024 Total of 47 panels and 7 batteries, 1 electric car panel System 1 and additional battery are under NEM 2.0 [roughly exported kWh offsets imported kWh over a yearly period] System 2 was not installed until SCE provided guidance that would permit additional panels with batteries without having both System 1 and 2 under NEM 3.0 [exported = 0.25 x imported] as long as the system was set to NOT export. We are hopeful that the guidance will be honored but this is still pending approval by SCE. Cori is very knowledgeable about all products and the industry as a whole. Communication is very prompt and informative. System builds are tailored to homeowner goals, including communication with Generac Generator, and budget. All aspects of the installation are handled by ParagonSun, including engineering plans for the system, communication with the city for permits and onsite meeting with city inspector. All paperwork is filled out and submitted to the electric company for approvals, and, when necessary, communication and scheduling of roofers like we needed for system 2 (see positive review for King Roofing) Initial estimates are final costs; we never experienced any additional charges. Electricians are experienced and efficient, and cannot say enough kind words about her colleague, Josh. Work is thorough, and all aspects of the installation are considered, including cosmetic touch-up. Enphase products are high end, operating consistently with minimal issues, and tech support is very accessible at almost all hours of the day. Do not consider anywhere else! This is the best of the best.

    It's 630PM and barely any power usage from the grid.

Our electrical panel is located on the…read moresecond floor, so running the wiring down to the garage on the first floor was quite a challenge. Eric was very experienced and did an excellent job identifying the direction of the ceiling joists on the first floor. He was able to precisely determine the best locations to make openings in the ceiling to run the wiring, which made the installation much more efficient and minimized unnecessary damage. Before starting the work, Eric also took great care to protect our home from dust. He covered the floors and other areas that could easily get dusty with protective plastic sheeting. He was professional, knowledgeable, careful, and reasonably priced. We're very happy with his work and would definitely recommend Eric to anyone looking for a reliable electrician for an EV charger installation!

When I…read morecalled mid day he informed me that he only did the automobile plugin stuff but asked where I lived and if the light switch was the only thing I needed fixed. When I said Lake Forest and yes to the only thing needing a fix, he said he would come by in about an hour. When he came he immediately went to work on the switch and in less than a minute the lights were back on, but the lights were flashing on and off. This was a problem before the lights stopped coming on altogether. He switched some of the light bulbs with other working lights in the hallway and they worked in the kitchen and began flashing in the hallway. To that, Eric determined that the flashing lightbulbs were "crap", recommended getting some new light bulbs to replace those that flashed. It wasn't the switch that was faulty but the lights themselves. Eric said that he would not charge me anything for his work that day which was so generous and appreciated by me. You don't find people like that anymore. As it turns out he has family living in my neighborhood. He also gave me some advice on another outdoor light that we are repairing. Can't say enough good things about Eric.
