Evergreen Solar reviews

The Verdict
Evergreen Solar is not worth the risk. We found a company that delivered strong work when motivated but abandoned customers once the checks cleared. One homeowner still hasn't gotten the two panels Evergreen promised to fix an undersized system, four months and $500 in unexpected utility bills later. Another has been routing a 200-foot extension cord from their water shed to their house every time the power goes out because the backup battery was wired wrong and no one returns their calls. The pattern is consistent across recent reviews: responsive sales process, competent installation crew, then radio silence when problems emerge. Three reviewers report unanswered emails, texts, and calls stretching across months. One homeowner couldn't even get a part number for $20 trim caps after two follow-up attempts. We noticed several earlier reviews praising fast timelines and transparent communication, but the 2021-2024 reviews tell a different story. When your roof springs a leak or your system stops producing power, you need a company that picks up the phone. Evergreen's warranty promises look meaningless if they've gone dark.
If you need post-install support or warranty work at any point in the next 25 years, look elsewhere. The installation might go smoothly, but once they have your money, getting them to return a call is apparently impossible.
Reviews That Shaped Our Verdict
Elizabeth invested a lot of money in a home solar system with a backup battery expecting the house to stay powered during outages. Instead she discovered that when the grid goes down only power reaches her watershed, not the house, so she ended up running a 200-foot extension cord from that watershed into the home to keep the refrigerator and essential outlets alive. She has contacted the company several times, but the problem remains unresolved and the installer refuses to respond to her emails, texts, and calls. The most striking detail of her experience is that a paid-for backup system leaves her improvising with an extension cord — she will update the review if the company actually fixes the backup power routing so she no longer needs that makeshift solution.
Pablo hired Evergreen Solar for a residential system after a friend recommended them. The company promised he would never see another PG&E bill, guaranteed a 30-year warranty and repair support, and told him to call if anything went wrong. A year later he got a true-up bill for more than $500, so he called and the crew promised again to come out, install two more panels and fit a meter to track production versus usage. He discovered the system had been undersized from the start and that the two panels and meter should have been part of the original install. For the past four months he has been trying to get them to return with no luck and is still waiting for the plans that spell out what type of system he actually has. What sticks with him is not the initial sales pitch but the $500 true-up and the promised follow-up work and documentation that never materialized.
Justin B. began the process by calling about a rooftop solar system and immediately connected with Zayith, who answered on a weekend afternoon and patiently walked him through system choices and financing. Even when Zayith was out of state on vacation he returned Justin’s call and spent time revisiting options; when Justin changed his mind about a financing plan, Zayith listened and helped arrange the alternative and put him in touch with the bank. On install day the crew arrived on time, stayed polite, and completed the job in a few hours — the panels, inverter, and conduit had a clean fit and finish. After the utility (SMUD) approved the system, the crew returned to install a wireless monitoring module that has worked reliably since. A few weeks later Zayith stopped by in person to check that everything was performing and to make sure Justin was satisfied. The one blemish came after installation: Justin noticed the black mounting rails had shiny silver cut ends that stuck out visually, so he emailed asking only for the manufacturer name and part number for simple plastic end caps he would buy and install himself (he made clear he wasn’t asking for extra work or money).

What You Can Expect
Phil had Evergreen Solar install a system in 2018 and watched crews return several times over the years for warranty repairs; he appreciated how responsive they were early on. Beginning in November 2023 he started trying to reach the company but ran into silence—calls to both Ben and Zayith went unanswered. He did connect with Ben once in November, and Ben promised to come out, but numerous follow-up calls went unanswered. The experience flipped from reliable post-install support to months of radio silence, leaving him wondering whether Evergreen Solar is still in business.

Hooman found Zayith, Ben, and the crew to be the most transparent team he could hire for his household's solar needs. They undercut competing bids on price while still delivering hands‑on service: Zayith spent an entire day making sure he was looked after, walking him through every step and answering even the most detailed questions. Zayith also explained how the business operates and emphasized their commitment to fair customer service, and the installation crew worked professionally, hard, and with clear attention to detail. A year after the install he remains very happy with the investment — what stuck with him was the day‑long personal attention paired with straightforward pricing and a tidy, durable installation.
