What We Install in San Jose
Evolution Solar is a Northern California contractor installing solar, home battery storage, roofing and heat pumps for homeowners across San Jose. We are based in Santa Clara, roughly fifteen minutes from most of the city.
Many companies selling solar in San Jose are sales organizations that hand the signed contract to a subcontractor. We are not. The same company that designs your system pulls the permit, installs it, meets the inspector and files the interconnection paperwork with PG&E. There is one phone number, and it does not change after you sign.
Whether you are going solar for the first time, adding a battery to a system installed years ago, replacing a failing inverter, or coordinating a new roof with a solar project, we can design around the house you actually have.
Solar Panel Installation
- Designed against twelve months of your actual PG&E usage
- Sized for the loads you are about to add, not just the ones you have
- Shading studied on the roof, not estimated from satellite imagery
Battery Storage & Backup
- Tesla Powerwall, Enphase, Franklin and Sol-Ark systems
- Whole-home or critical-loads backup, priced honestly against each other
- Storage added to solar that is already on the roof
Roofing + Solar Together
- One contractor and one schedule for both trades
- Avoids paying twice to remove and reset an array
- A straight answer on how much life the roof has left
Repair & System Upgrades
- Inverter and microinverter failures diagnosed on site
- Monitoring that has gone dark, and production that quietly dropped
- Panel removal and reset when the roof comes off

Beyond Residential

Working With PG&E
San Jose is Pacific Gas & Electric territory, so residential solar here interconnects under PG&E's rules and California's current net-metering tariff. That matters most for homeowners who went solar years ago: modifying an older system can affect its legacy interconnection status, and the modification should be reviewed before any equipment is ordered. Neighboring Santa Clara is served by Silicon Valley Power instead, under a different set of rules — worth knowing if you are comparing notes with someone a few miles away.
San Jose Permitting
Solar and storage projects in San Jose are permitted through the City of San Jose Building Division and must satisfy electrical, building and fire requirements before the utility will grant permission to operate. We prepare the permit package, coordinate inspections and handle the interconnection filing as part of the project rather than leaving it to the homeowner.
