SunSolar U.S. reviews

Lou was dealing with a 2009 legacy string solar setup on his roof — 27 panels at 210 watts each — when the inverter finally quit after 17 years. He reached out to more than five installers hoping for a straightforward inverter replacement, but nearly every one pushed for a full tear-out and replacement that would have run more than $16,000, plus a separate $300 site visit just to explain what needed fixing. The standout was Kobi at SunSolar US, who came out without charging an ‘inconvenience’ fee and looked at the system the way it actually was: panels still performing well and worth keeping. Instead of starting over, he helped Lou reuse the existing array, added solar optimizers to each panel, and swapped in a new inverter, cutting the cost by about half. The upgrade also brought detailed monitoring at the individual-panel level and left the system ready for battery storage later on. Lou saw production jump about 10% in March, expects even better gains in the summer, and had the whole job finished in two days with a crew that was punctual, tidy, and professional.

Nina had already been living with a SunSolar system for 10 years when the company came back into the picture, this time for her daughter’s home. The long-running system on her own house was still working perfectly, which set the tone for the new install. What stood out most was Kobi’s responsiveness: he handled things efficiently and jumped on calls right away whenever they came up. That combination of a decade-old system still running smoothly and a fresh installation for her daughter gave the experience a rare kind of credibility that’s hard to fake.

Duy Pham had Kobi install his first solar array seven years ago, and the system is still producing reliably with only minimal loss in efficiency despite never having the panels cleaned. When rising energy costs and heavier household use made more capacity necessary, he opted to add panels to boost output. Kobi moved quickly: within days of discussing options he pulled a plan together and finished the expansion even faster than the original install. He stayed highly responsive and generous with his time, answering questions and addressing concerns so the upgrade felt easy and almost effortless. The detail that sticks: a seven-year-old array that’s held up without maintenance, and an installer who turned a retrofit into a matter of days rather than weeks.

Debbie Y. had a 19-panel roof system installed on her single-family home and, a year after the work was finished, she hasn't paid an electric bill. Kobi from SunSolar U.S. visited, spent quality time with her and her husband, and carefully walked them through the installation process. From that first meeting through the installation, the crew stayed professional and focused on the details needed to complete the job. Kobi and Ron answered questions quickly and remained reachable whenever she needed help. The standout detail: one year in, zero electric bills — paired with fast, hands-on communication whenever questions came up.

Winston had a solar system installed about five years ago and still remembers the first meeting with Kobi as a highlight — Kobi walked him through the technical details carefully, a clear contrast with other companies that tried pressure tactics and glossed over explanations. The installation went smoothly and professionally, and the system has produced more energy than the initial estimates predicted. The most memorable part of the experience has been SunSolar’s ongoing support: when the inverter developed a manufacturer fault, SunSolar handled repairs and replacements quickly and efficiently instead of leaving him to navigate the warranty alone. He values that prompt, hands-on service and the company’s long track record; five years later, what sticks with him is how SunSolar took responsibility and resolved a hardware problem without hassle.

A year ago Aaron D. had SunSolar US install a 5.6 kW solar system on his house, and what stood out immediately was the technical approach: an engineer came to the site instead of a high-pressure salesperson, and he answered every detailed question. He found the crew responsive throughout the process as they took care of permits, the install, the inspection, and the back-and-forth with SCE. As part of the job they also replaced his aging electrical panel — and did it for about $1,000 less than his regular electrician had quoted. Over the past year he experienced no roof leaks or equipment problems and steady, problem-free generation. Despite a significant unplanned jump in electricity use from working at home and losing workplace EV charging, his true-up with SCE is running about $30 for the year. He walked away convinced that the combination of engineering expertise on the front end and the cost-saving panel upgrade made the project worth doing.

After about four years with solar panels on her home, Susana Murillo discovered they continue to deliver excellent efficiency and has been very happy with the outcome. She worked with Kobi and Ron, who walked her through options with clear, honest information and put together financing plans that fit her needs. The upfront transparency plus reliable long-term performance made the switch feel like the right move — she still calls it the best decision she made and thanks Kobi and Ron for their help.

Lonnie Vu had a rooftop solar system installed in February 2019 and quickly discovered a big change: he hasn't owed SDGE anything since the install. The summer bills that once ran $500–$700 simply disappeared. He ended up with an installation that matched the sales pitch—Kobi and his crew provided solid service and delivered what they promised. The detail that sticks with him is the ongoing elimination of those steep summer charges.

Ruth installed a 20-panel system on her ranch-style home four years ago and discovered it dramatically reduced her cooling-season costs — summer AC no longer spikes the bill. She now pays between $2 and $11 a month for electricity, most months around $9–10. The installation came quickly, was hassle-free and neatly done, even while other contractors were working on a remodel; she noticed Sun Solar’s crew provided the best service on site. The panels have performed consistently since day one, and she wishes her heater were electric so she could save even more. The takeaway that sticks: four years later, a 20-panel setup that reliably keeps monthly bills in the single digits.
