The Verdict
Westhaven Power is a gamble you don't want to take. We found a company whose install crews can do solid work, then the problems hit months later and the support structure collapses. One customer paid $80,000 for solar, HVAC, and a generator in 2020, then watched their salesperson, three install foremen, and service technician all quit within 15 months. When they called for routine HVAC maintenance, the company said they don't do that anymore. Another homeowner's system went down in 2021 and Westhaven didn't send anyone out until March 2023, then billed $200 an hour for labor despite a 10-year parts-and-labor warranty. Reviews show 95 mentions of value problems and 92 complaints about post-sale support, twice as many as positive mentions. The company installed non-compliant inverters that PG&E wouldn't accept, left roofs leaking, and walked away from unfinished work. If a tech named Daniel or Tracy happens to be assigned to your account, you might get lucky. But counting on luck to protect a $30,000 investment is not a strategy.
If you're hoping an installer will still answer the phone two years from now, this is not your company. Look elsewhere.
3 Stories That Stood Out
Mark Warner invested more than $80,000 in a major home upgrade — a five-ton HVAC with two extra zones and an added return, a 30-panel solar array, and a 22 kW backup generator. The installation crews turned up experienced and did a flawless job on all three projects, leaving him with well-built systems that performed exactly as expected. Nine to twelve months later the picture changed. He discovered the salesperson who handled the sale had already left the company, but he still had contact numbers for two of the three foremen and used those numbers to get answers when questions came up. A year in, he called to schedule HVAC servicing ahead of summer and encountered resistance from the service manager, who initially refused before dispatching a technician. That technician walked him through routine maintenance, warned he probably wouldn’t be allowed to perform the same help the next year, and handed over his personal number — a small lifeline that proved useful. By the time March arrived, turnover had thinned the team: the original salesperson was gone, all three installing foremen had moved on, and the helpful service tech was gone too. When he asked the company to add seven more
Roy J bought a residential solar system in 2015 with Westhaven acting as the installation subcontractor. The setup carried 25-year warranties on the panels and micro‑converters from **** and a 10‑year parts-and-labor guarantee from Westhaven. The system stopped producing properly in 2021, and when a true‑up from **** arrived in September 2022 he called Westhaven to have it checked. He waited: Westhaven did not send anyone until March 2023. When a technician finally came, they pointed to a failed name‑brand processor and insisted he would need to pay for the replacement, plus labor billed at $200 per hour. Three months of unanswered emails and phone calls followed, then Westhaven informed him they were no longer a subcontractor for **** and refused responsibility for repairs. **** confirmed they had severed ties with Westhaven and sent a different subcontractor, who replaced the processor and all the micro‑converters. After that work, his monthly energy usage dropped by about 50% and his true‑up was the lowest it had been in two years. Roy gave one star because the company stopped communicating after the sale, failed to honor the 10‑year parts and labor arrangement, and—he believes—
Paul A. hired the company for a solar install that also involved roof and gutter work on his home, and at first he loved the installation crew — the people who put up the panels did an excellent job. He quickly discovered, though, that the positive start didn’t last: unfinished work went ignored and he spent two years trying to get the company to respond to calls with no success. The roof began to leak and the newly installed gutters flooded his entry, but the contractor refused to repair them, arguing the problems weren’t covered by the roof contract. On top of the water damage, the new power system underperformed compared with his old setup, and the inverters turned out to be non‑compliant so PGE wouldn’t accept his excess power. The financial consequence showed up in his utility statements — his True Ups are now almost twice what they were before. His takeaway: a skilled installation crew started the job, but once the company was paid he was left with leaks, a flooded entry and higher bills while repairs and compliance issues went unresolved.

What You Can Expect
j t had a Westhaven Solar system installed in Sacramento and the initial installation through final inspection went smoothly. Five years on, when overall solar production dropped, Westhaven stood by the product. William and Tracy stayed on top of the situation, kept j t informed, and quickly scheduled a technician visit. Daniel the technician arrived, methodically analyzed the array, and discovered a surprising culprit: a cabinet was blocking an outlet. He devised a practical fix, repaired the issue, and restored the system’s performance. j t walked away impressed by the company’s responsiveness and by the technician’s hands-on problem solving — the memorable detail being that a thoughtful on-site solution to a cabinet-blocked outlet fixed what felt like a major production problem.
Wild Boy MX purchased solar from Westhaven in 2022 and found the whole installation process straightforward and easy. When PG&E briefly changed rules that jeopardized his permission to operate, Westhaven stepped in and offered to cover any required upgrade costs. PG&E later reversed the change, but Westhaven’s willingness to absorb that expense without billing him made a powerful impression. About two years on, his system has run flawlessly. He calls PG&E "crooks," and the detail that stuck with him is Westhaven’s readiness to pay for potential upgrades — that reassurance turned a regulatory scare into a non‑issue.
Tiffany invested in a $50,000 solar-plus-battery system for a house with four adults home all day, hoping to eliminate the electric bill. She discovered the system was substantially underpowered: the batteries never fully charged during daytime use, so the setup couldn't carry the household through the night. She pressed Westhaven to fix it and even offered to pay for additional panels if they would install them; technicians up to the Director of Operations agreed the system was too small, but the CEO declined to engage. The installation itself was rocky — crews took more than a month to complete the work, apparently doing just enough to secure payment from the finance company, then failed to hook the system up without her making three calls. When the array came online, they had only connected one battery and system reports looked wrong, prompting more calls. Crews broke some household items, tore up flagstone, and a third electrician visit still didn’t resolve the issues. The system went in during the first week of January 2024 but wasn’t fully functional until September 2024. The clearest takeaway: a pricey system that couldn't meet heavy daytime demand and took eight months of h
Stan called Westhaven when his battery lost its Wi‑Fi connection, and they fixed the issue immediately. He’s had the solar panels for just over a year, and the system has run reliably with no malfunctions. The standout detail for him was the prompt, effective support for a minor connectivity problem — proof, he feels, that the company stands behind its work and a reason he tells others Westhaven is an easy choice for anyone thinking about going solar.
Anna gave the company two stars after a frustrating run of problems with her roughly year-and-a-half-old solar-plus-battery system. She ran into trouble when a bad cell took the battery down, and two days later the whole solar array went offline — the display showed the system had been turned off even though no one had done that. Westhaven required a paid diagnostic visit at $200 an hour just to send a tech, and although the system briefly came back online the battery remained out of service. Daniel, the service technician, emerged as the saving grace: he routinely calls to troubleshoot instead of firing off emails, explains the system more clearly than the installer or the salesperson did, and when he happened to be back for another job he diagnosed the main battery fault, fixed what he could, and arranged for a replacement cell. She expected warranty coverage for a system only 18 months old, but the warranty handling felt inadequate and left her facing service charges for problems she didn’t cause. What lingers from her experience is Daniel’s thorough, hands-on help — and the surprise $200/hour diagnostic fee despite the system’s young age.
Alexander chose Westhaven two years ago after comparing three companies and had a 6 kW system installed on his home. Since then he’s spent far more time on the phone than he expected—mainly with Abby at the office—and has gone through multiple service and tech staff trying to sort persistent problems. A technician eventually acknowledged what he had been experiencing: his house actually draws about 10 kW, so the system is undersized. The result is that running the dryer in daylight drains the batteries, and running the AC on a sunny day both depletes the battery and pulls from the grid at the same time; by about 5 p.m. the battery is low and the home stays on the grid for the rest of the night. Despite talking to many people at the company, nothing has been done to fix the mismatch. He wants Westhaven to get back to him with a plan to resolve the under-sizing—right now he’s paying thousands for a system that doesn’t meet his household loads.
Peggy had a solar array installed four years earlier and appreciated prompt, competent service when a problem cropped up. Jason — who’d been on the original installation crew — diagnosed the issue, found the fault, and repaired it quickly. Because he already knew the system, the visit was fast and straightforward, and she walked away with the panels back in good working order. The standout detail: the same technician from the initial install came back to fix the problem, keeping the system running smoothly.
Don Johnson had Westhaven install a solar-plus-storage system on his home about three years ago. He encountered a minor issue before receiving Permission to Operate, and Westhaven’s service team stepped in quickly to resolve it. Since activation the system has performed reliably, and the prompt, effective support during that pre-commissioning hiccup is the detail that stuck with him.
Jamie bought a $47,000 solar system and, after three years, discovered the array had stopped producing because the system’s circuit board failed. For about two months Jamie had no idea anything was wrong — they had assumed the company’s monitoring (a promotion offered at installation) would alert someone, but that monitoring had quietly ended without notification. When the company shipped a replacement board, it quoted $200 an hour for installation and offered no clear explanation for why the board failed so soon. Frustrated, Jamie refused to accept ongoing surprise repair bills for a product that had been sold and monitored as part of the package, and steered their parents away from the company as they watched the situation unfold. The detail that sticks: the monitoring promotion lapsed without notice, leaving panels offline for weeks while the company then sought steep hourly fees to fix a problem Jamie never caused.
