Your solar estimate
An estimate, not a quote: system size comes from your bill, production from NREL for your ZIP. No federal credit, rate increases, panel degradation or financing. How I calculate.
I went through utility interconnection records: 9,081 home solar systems were installed within 7.5 miles of central San Jose in 2022–2023, by 44 companies with 30 or more systems each. The five most active: Sunrun (1,428), Tesla Energy (1,158), Sunpower (961), Bright Ops (531), Self (235). Today, quotes average $2.52/W in San Jose (EnergySage, updated 2026-09-11) — about $17,640 for a 7 kW system before incentives.

Is solar worth it in San Jose at today's prices?
San Jose utilities credit exports at hourly values with no single rate, so here is a lower bound: a 7 kW system at today's average quote of $2.52/W, counting only the half of production used at home and giving exports a value of $0.
| Utility | Typical energy charge | Net cost, 7 kW | Savings/yr (self-use only) | Payback, at most |
|---|---|---|---|---|
| Pacific Gas & Electric | $0.366/kWh | $17,640 | $2,082 | 8.5 years |
Export credits shorten this; how much depends on your hourly export profile. No federal credit, no rate increases or degradation — full method.
