Mercury Solar reviews

The Verdict
Mercury Solar disappears when things go wrong. We found a troubling pattern: customers who need warranty service, repairs, or help closing permits hit a wall of ignored calls and unanswered emails. One homeowner has been chasing Mercury since 2019 to close a permit so he can sell his house. Another paid for a year on a system that was never installed, with the permit mysteriously canceled. A third watched battery covers warp and spring off while Mercury screened his calls. The company does have loyal repeat customers who rave about the owner's technical expertise and bill savings that dropped one household from 250 dollars monthly to under 14 dollars. But those wins came during the sale and install. After that, you're on your own. We counted 14 reviews describing post-sale abandonment versus 13 praising the installation itself. The math is simple: Mercury may show up to put panels on your roof, but when something breaks or paperwork stalls, you'll be the one left in the dark.
If you can handle being your own warranty department and don't mind chasing a contractor for months when things go sideways, the upfront pricing might appeal to you. But if you expect a solar company to answer the phone after cashing your check, look elsewhere.
Reviews That Shaped Our Verdict
Patricia and her husband have been making payments for a year toward a PV system they still don’t have. They grew increasingly frustrated by vague answers about the delay; when her husband called the permit office he discovered the permit had been canceled. He tried to get the issue resolved by speaking with Scott at the company, but those efforts produced no fix. The company repeatedly offered to send money to offset their electric bill, but those payments had to be claimed on their taxes and didn’t address the real issue. After a year of payments with a canceled permit and no installation, what stands out is that they keep getting workaround credits instead of the solar system they paid for.
Lawrence has been living with an off-grid battery backup system Mercury Solar installed on his home in 2015, and the experience has been a long string of reliability problems. He endured constant power surges that drove the system to flip between HECO and the solar battery as often as four times a minute, forcing him to manually switch to HECO to stop the cycling. Those surges killed a split AC, a refrigerator, a dishwasher and other appliances, so he ended up replacing them and then installing a power surge protector and a UPS as stopgap measures. To limit damage and instability he now flips the system to HECO after 7 p.m. and back to solar in the morning if it’s sunny. When a recent outage left his garage and bedroom without power even after switching to HECO, he contacted Sue for help and then emailed owner Scott Sparkman; on 1/20/2024 Scott wrote he had COVID and would send a technician. He exchanged emails through 2/22/2024, but no one ever showed up, and his repeated calls and messages went unanswered. The bottom line that stuck with him: persistent hardware-induced outages and appliance damage, plus a promised service visit that never materialized, left him relying on manual
J. C. discovered a completed solar installation from 2019 that never had its permit closed, and that unresolved paperwork has become the central problem. They paid the full contract amount for a 2019–2020 install, but the city still lists the permit as open. When the permit office contacted them, the office pointed back to Mercury Solar as the party dragging their feet. Mercury Solar acknowledged in 2022 that only a few minor items remained to pass inspection — and yet three years later those items still haven’t been resolved. They struggled to reach anyone at the company; calls rarely get answered. That lack of follow-through has practical consequences: because the permit remains open, they’ve had to delay or miss potential buyers while trying to sell their house. Frustration mounted into a simple demand — finish the contracted work and close the permit — and a clear offer to change the review to five stars once it’s done. The standout detail here is not poor panel performance or a bad install, but years of post-install administrative neglect: paid in full, installation finished long ago, yet the permit closeout lingers and is actively interfering with a home sale.

What You Can Expect
Mary D. hired Mercury Solar in 2012 to outfit her home with a 13-panel system and then expanded in 2019, adding six more panels and an off-grid battery. She found Mercury’s price tags ran about 30–50% lower than competing estimates, and the result translated into a dramatic drop in utility costs — her electric bill fell from nearly $250 a month to under $14. The installations have performed with no major problems, and Mercury stayed responsive whenever questions came up; she singled out the office manager Sue as particularly attentive. Scott, the owner and system designer, combined hands-on electrical and plumbing know-how with business savvy, and she called him genuinely helpful when walking through payback calculations, rebates, financing, and different system options including hot-water panels and off-grid setups. Mary highlighted Mercury’s long track record — in business since 1979 with thousands of systems installed — and urged shoppers to ask the company for two or three customer references and to talk directly with Scott to get an accurate picture. Her practical takeaway: verify references rather than relying on unvetted online reviews, and be prepared to see a substantial,可

Herb phoned the company five times over the course of a year about his Mercury-installed residential solar system after it began showing problems that couldn’t be diagnosed remotely. Each call produced a promise—to send a technician or to schedule an inspector—but no one ever showed and responses stopped coming. Because Mercury was the original installer, he expected a routine checkup; instead he spent months waiting with the issue unresolved. After roughly a year of silence and broken promises, he gave up trying to get support and the system remains undiagnosed.
