What We Install in Fremont

Evolution Solar installs solar panels, home battery storage, roofing and heat pumps for Fremont homeowners. We work out of Santa Clara, a short drive down 880, and we run our own crews rather than selling projects to a subcontractor.

Fremont has a particular profile we see constantly: a large stock of homes that already went solar five to fifteen years ago, and one of the highest concentrations of EV ownership anywhere in the country. Both change what a good system looks like. A lot of our Fremont work is not first-time solar — it is adding storage to an array that already exists, or resizing a system that was designed before the household had two electric cars.

We also handle the less glamorous work: failed inverters, microinverters that stopped reporting, and panel removal and reinstallation when a roof needs replacing.

Working With PG&E

Fremont is Pacific Gas & Electric territory, so solar here interconnects under PG&E's rules and California's current net-metering tariff. For Fremont specifically, the interconnection question that comes up most often is not new solar — it is what happens to an existing system when you add a battery. If your array was installed under an earlier net-metering agreement, the modification needs to be reviewed against that agreement before equipment is ordered, not after.

Fremont Permitting

Solar and battery projects in Fremont are permitted through the City of Fremont's Building & Safety division and must clear electrical, building and fire review before PG&E will grant permission to operate. Battery installations in particular draw fire-code scrutiny around placement, clearances and egress. We prepare the permit package, handle the submittal and meet the inspector ourselves.

"I recently chose Evolution Solar for my solar installation, and the experience exceeded my expectations. After seeing their quality work on my neighbor's home last October, I reached out to George, who patiently explained the process and provided a detailed quote... Despite initially hesitating, I revisited Evolution Solar when PGE announced new fees for solar customers March this year..."

Paul Hsu

"We used Evolution solar for our solar panels almost a year ago. The process was fast and easy, and any questions we had were promptly answered. In fact, any questions we've had since having then installed have been answered promptly. They were very friendly, professional, and they handled everything that needed to be done with the city and pg&e. I highly recommend then"
