Best Solar Installers

San Francisco

Sutro Power

Sutro Power runs one of the tightest solar operations in San Francisco. We analyzed their work and found zero complaints about installation quality, zero complaints about sales pressure, and zero complaints about follow-up support. One homeowner postponed two panels for six months while finishing ot

Albion Power

Albion Power earned our unreserved recommendation. We analyzed dozens of reviews and found a company that treats rooftop solar like the engineering project it is, not a commodity sale. One homeowner watched six other installers hand over quotes based on outdated satellite photos; Albion's estimator

Luminalt Solar Energy Solutions

We recommend Luminalt without reservation. They installed SunPower panels on a three-story Victorian with a battery location problem that another installer gave up on after months of silence, then worked through fire code exceptions and got pre-approvals before installation so inspections sailed thr

All Bay Solar is a solid choice if you want an installer who handles roofing, electrical, and solar under one roof. We analyzed dozens of reviews and found a consistent pattern: crews complete installations in a single day, leave no debris behind, and the owner answers the phone on Sundays when some

A 24 Electric will answer your panicked Saturday call and walk you through a fix over the phone at no charge. We found over forty reviews describing Eddie, the owner, doing exactly that: one homeowner lost all power at 9 PM, called eleven electricians, and only Eddie picked up (from overseas, on vac

CleanFactor Energy is not worth your time or money. The owner stops returning calls once you send a deposit, leaving projects incomplete and permits unfiled for months. One reviewer in Redwood City waited six months and eventually discovered the company never even submitted permit paperwork despite

This company can nail the installation, then leave you stranded when something breaks. We analyzed dozens of reviews and found a sharp divide: homeowners who sailed through permitting in five minutes and are still getting callbacks seven years later, and homeowners who can't get a returned email thr

SolarUnion operates in two modes, and your odds depend entirely on which one you get. We analyzed hundreds of reviews and found a company that handles routine installations competently but collapses when anything goes wrong. One homeowner's inverter failed after a single year, SolarUnion blamed the

This company isn't worth the risk. We analyzed hundreds of reviews and found 31 customers stuck in months-long delays with spotty communication and unfinished installs. In one case, a homeowner waited a full year from contract signing to a working system, cycling through multiple disappeared project

Sunlight Financial is a lender you hire indirectly when your solar installer chooses them for financing, and once you sign, getting help becomes a serious problem. We found repeated accounts of customers stuck paying for broken or never-completed solar systems after installers went bankrupt or aband

Ra Solar is not a safe bet. We found dozens of reports of equipment failures left unresolved for months, customers forced to hire outside electricians at 10% of their original install cost, and allegations that the company filed for bankruptcy with no assets to pursue. One homeowner's system went do

Sunrun will charge you while your panels sit broken. We analyzed thousands of reviews and found a company plagued by systemic breakdowns that leave customers trapped in multi-year cycles of non-functioning systems and finger-pointing. One homeowner reported paying $111 monthly for over a year while

HelioPower installed systems that routinely failed to deliver promised savings, then disappeared when customers needed help. We analyzed nearly a hundred reviews and found a clear pattern: professional installations followed by expensive utility bills and unanswered service calls. One homeowner paid

Tesla Energy is gambling with your home. We analyzed thousands of reviews and found a company that can't activate systems, miscalculates energy production, and leaves customers trapped in 20-year leases with higher bills than before they went solar. One homeowner paid $78.69 into their utility's cre
