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.
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.
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.
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).

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.
Dylan chose Evergreen Solar to put panels on his home and found the whole process effortless — from the first site visit through final activation. He experienced a professional, knowledgeable crew that kept him updated at every milestone and handled paperwork and scheduling without friction. The installation itself stood out: fast, tidy, and completed with genuine attention to detail, leaving the roof neat and the site cleaned up. What he'll remember most is that combination of constant communication and a spotless, meticulous install — the clear signs that the job was done right.
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.
Ashley moved into a home with solar panels already installed but, to her surprise, never connected to the grid — a rude awakening when she tried to make the system work. She reached out to several companies that tinkered around the edges but left the job unfinished, then finally got in touch with Joel, whom she’d used before. Joel sent Erik out within a week, and they finished the commissioning work that other crews hadn’t completed. Evergreen handled the whole process quickly, efficiently, and with steady communication, and Ashley regretted not calling them from the start. She singled out Joel and Erik for turning months of dead panels into a working system in just days — a clear takeaway for anyone facing an installed-but-not-connected solar setup.
Linny Crow chose Evergreen Solar to make the switch to solar and discovered the installation wrapped up far sooner than expected. They watched a hard-working, respectful crew handle the site with care while a transparent, informative sales team patiently answered every question. The whole project moved smoothly from the initial conversations to finished panels — what stuck with them most was the crew’s professionalism and the sales team’s willingness to explain details, the kind of practical attentiveness that makes a big installation feel low-risk.

Erin C. endured nearly six months of back-and-forth trying to get Tesla to install solar. Frustrated, she went to EnergySage for quotes, called EverGreen, and connected with Zayith right away. EverGreen moved quickly: they designed, scheduled, and had the system set up and installed within a month, with the on-site crew finishing the install in a single day. They also prepped the layout and electrical planning so the array can be expanded when she completes an addition. She appreciated the fast turnaround and the team’s advance planning for future growth.
Thomas M. shopped around with half a dozen solar companies before choosing Evergreen Solar to install a 30-panel system on a Livermore roof that needed some minor repairs. He discovered Evergreen offered the most competitive combined quote and handled the permitting and system design smoothly. The installation crew arrived friendly and conscientious, working quietly around the infant’s and toddler’s naps and accommodating his wife’s breastfeeding schedule. Midway through the job the crew accidentally drilled into a fire sprinkler line; the leak was stopped quickly, the team apologized and accepted responsibility, and Evergreen both performed repairs themselves and brought in other contractors as needed. The damage was resolved fast and at no extra cost. The system is running as promised, and what stuck with him was the company’s follow-through—fixing a significant on-site mistake without passing the cost along, while still delivering a competitively priced installation.
Yadira Contreras signed a contract in September 2022 for a combined roof and solar installation after being told the system would be operating within two months. She ended up paying for a new roof and solar panels but discovered the solar never got connected, and the roof now leaks with rotten wood visible. The salesperson, Juan Amalla, stopped answering her calls, and the company hasn’t honored the promised lifetime roof warranty or made any repairs. Meanwhile she continues to pay for electricity despite having paid for the solar system; she intends to remove her comment only when the company fixes the situation.
Long-term satisfaction for Evergreen Solar drops to 2.0 ★ compared to early reviews. This decline is worse than 75% of installers we looked at.
Long-term reviews carry the most weight in our methodology because they are most representative of what you should be paying for: a system that will perform for years.
