This installer is too unreliable to risk your money on. We analyzed dozens of reviews and found a dangerous split. Some projects sailed through with responsive crews and well-sized systems, but 15 customers described the same nightmare: equipment failures within months of install, support teams that vanish after payment clears, and unresolved issues dragging on for weeks while homeowners rack up double utility bills. One buyer watched five inverters fail before the system hit six months old, then was asked for a credit card on file before anyone would come look at it. Another paid cash upfront and spent three months chasing the company for a promised rebate check that never arrived. The pattern is clear. When things go right, you get a clean SunPower install and competent billing. When things go wrong, you're stuck with a broken system, no monitoring alerts, and a support line that only calls you back after you've already paid. The post-sale abandonment shows up in too many stories to ignore.
If you're weighing quotes, consider that the sales experience here is smooth but the post-install support collapses under load. Multiple buyers reported months-long delays, silent monitoring failures, and unanswered calls after payment cleared. Better installers exist.
Ariel T. had a home solar system installed just over a year ago and discovered two frustrating failures after the crew left — despite being told the company would monitor the system. First, the array never got turned on at the start; it sat off until Ariel kept calling and pushing the company to activate it, even though the job had already been paid for. A few months later, production plunged: what used to cover over 100% of daily use on sunny days fell to about 60–75%, and utility bills ballooned — at one point a more than $100 bill from Duke and roughly $500 in extra charges overall. When Ariel asked the company to check, it took repeated prompting before a technician acknowledged that “multiple inverters” were down. Rather than dispatching someone immediately, the company demanded a credit card on file because, they said, if the problem wasn’t their fault Ariel would be charged — even though the failure began within about five months of installation. A technician is scheduled to inspect the system in three days; for now the starkest takeaway is that monitoring was promised but the homeowner had to chase every step and was left carrying higher bills while the company delayed a on
In mid‑2019 george.riemer signed up for a residential tier II rooftop solar system, completed the final paperwork on July 2 and put the required umbrella insurance into effect on July 25. Project engineering wrapped on August 2 and the permit was filed — then months of silence followed until he called in October to ask when installation would happen. An installation date in November was canceled, and after multiple calls the crew finally showed up in December, by which time the 30% tax credit window had become a pressing concern because the sale had been six months earlier. What unfolded on the roof became the clearest source of frustration. Installers began locating rafters by pounding into newly laid shingles, leaving him worried about needless damage. A job that should have taken three days stretched into a week and still wasn’t finished; the electrician left an opening into the attic for two weeks before returning only after repeated complaints. By January 2020 he felt uncomfortable paying in full before the system worked, but he paid cash anyway. Connectivity promised at the point of sale turned into another battle: he had been led to expect a cellular link for the weather
John Alevras discovered Nicole Barenchi of ESA to be the linchpin for a family project involving his parents and him. From the first meeting through the final steps, she guided them step by step, patiently explained every detail, answered all their questions, and repeatedly went out of her way to resolve issues — never giving up until things were finished. He walked through a process that might have been frustrating and instead encountered what he calls the best customer service he’s experienced: Nicole remained pleasant, caring, empathetic, candid, insightful, thorough and professional, with a steady sense of humor whenever challenges arose. She dug into problems, offered clear guidance, and kept momentum so the project could move forward. There’s no doubt in his mind the job wouldn’t have reached completion without her tireless effort and personal attention — that relentless commitment is the detail a future customer should remember.

Mike I had an 11.4 kW solar system put on his home in 2018 and bought the company’s removal/takedown package up front. A few years later an insurance-driven roof replacement made that package necessary; ESA came out, took the panels down and reinstalled them when the new roof was finished. That follow-through mattered — several roofing contractors warned him that some solar firms squeeze customers over removal and reinstallation — so he was relieved to find ESA honored the contract and handled the work without issue. The detail that stayed with him: paying for the removal/reinstall option actually prevented the reroof from turning into a headache over the solar panels.
Eleanor jumped at the chance to outfit her suburban home with solar panels and a Sonnen 10 kW battery for continuous power. She ended up with the maximum number of panels crammed onto her second-story metal roof—even squeezing production out of a south-facing area that carries shade—after the sales, engineering and design teams handled permitting and coordination with the local utility smoothly. The project dragged longer than she expected: she signed the agreement on April 15, 2019 and didn’t see the system go live until March 2020, a delay she attributes to the company having out-sold its onsite install capacity during a busy period. Once operational, one of the battery’s four components failed and the system stopped communicating over Wi‑Fi; installers responded quickly, came onsite to troubleshoot, and worked with SunPower and Sonnen techs by phone to get the unit and monitoring restored. She pushed company operations, engineering, and the monitoring providers to add a push-alert when telemetry stops coming in so faults get noticed immediately. Bottom line for her: the team delivered an efficiently engineered array in a challenging roof and fixed a tricky battery/Wi‑Fi problem,
Rebel poured hours into researching a solar system for a first home and expected a careful, on-time installation — instead they ran into a chain of delays and surprises that kept stretching the project out. The company gave a four-week window for permits; at week three they reached out and discovered the permits hadn’t even been sent because the company cited “unforeseen circumstances.” After waiting several more weeks, permits finally arrived and an install date was set — they were told the crew would need them home and that the work would take a single day. The night before, a technician fell off a roof and the company put the crew into “safety down status,” pushing the job back and forcing them to request additional days off and lose more PTO. On the revised install day they noticed two different panel styles by checking SunPower’s Instagram and were hit with an unexpected $3,000 upcharge for the all‑black panels, even though the website hadn’t indicated a higher price. The company asked them to sign a new contract via DocuSign, but the link didn’t work. What was supposed to be a one-day job stretched into multiple visits: day one ended with a promise to finish the next day; day

Jeffrey needed enough solar to power a larger, five-person home and chose Esa Solar for a substantial 16 kW array. Brooks came out, spent time walking him through how Esa’s panels compared with other companies, and carefully calculated the household’s needs until they settled on the right system size. Six months in, the array is producing as projected and the monitoring app makes the day-to-day win obvious — he can see generation, household use, and cost savings at a glance. The one real snag was administrative: Duke mixed his name across different pages (Jeff on one, Jeffrey on another) and couldn’t get that straightened out, which was a needless hassle. What sticks with him now is the reliable production and the clear, useful app that lets him watch the system deliver both environmental and economic benefits.

Christine Smith came to esaSolar after a bad experience installing solar on a previous home and a lot of homework. She interviewed four companies and chose esaSolar, and what stood out was how responsive they were and the quality of the equipment they recommended. Rather than pushing the priciest product line, the installer steered her toward options with a quicker payback, a decision she appreciated for its honesty about ROI. The system includes company monitoring and an app she checks anytime to watch real-time production, and a 25-year warranty provides long-term peace of mind. After installation she hasn’t been disappointed — the mix of upfront, practical advice, live monitoring, and a lengthy warranty is the detail that made this feel like the start of a sensible long-term service relationship.
Franklin chose esa Solar for his solar installation and discovered a team that paired professional workmanship with unusually accessible, informed support. He could pick up the phone and reach someone who knew the system; when he left a voice message or sent an email, he reliably received timely, informative follow‑ups with the exact information he needed. The panels and electrical work have performed without fault — no system or electrical issues since installation. What stood out most was the combination of prompt, knowledgeable communication and a trouble‑free system, so the concrete memory he keeps is being able to get clear answers quickly while enjoying uninterrupted performance.
John hired the company in 2019 to put solar on a tile roof and quickly discovered the crew lacked experience with that roof type. They left gaps in the tiles that had to be repaired, and the company only agreed to cover the cost after persistent pressure. The installation errors also triggered financial mishaps for him, so what stood out was not the panels but the follow-up: roof damage that required paid repairs and the financial fallout that followed.
Long-term satisfaction for SunPower by esaSolar drops to 3.2 ★ compared to early reviews. This decline is worse than 71% 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.
