Is solar worth it in Northern California?
Short version: for most homes on PG&E, yes — because PG&E’s rates are among the highest in the country and keep climbing. But it genuinely depends on your roof, your usage, and your utility. Here’s the honest breakdown for a Northern California home.
The short answer
If you own a PG&E home with decent sun and a normal-to-high electric bill, solar almost always pays off over its 25+-year life — the main question is how fast. PG&E rates have risen sharply for years, so every kilowatt-hour your panels let you avoid buying is worth more each year. The systems that win under today’s rules are sized to use your own solar, usually with a battery.
What makes solar pay off here
Three things stack in Northern California’s favor: very high electricity prices (often $0.40+/kWh on peak), good sun across the inland valleys and foothills, and rising rates that make future savings larger. Add a battery and you shift cheap midday solar into the expensive 4–9 pm peak — the difference between what you’re paid to export (a few cents) and what you pay to import (full retail) is exactly where the savings live under NEM 3.0.
When it doesn’t pay off
Be honest about the cases where it’s weaker: a roof with heavy shade that can’t be trimmed, a very small bill (little to offset), plans to move within a few years, or a north-only roof with no good plane. If you’re on a municipal utility with lower rates (SMUD, Roseville Electric, Redding, MID), the math is different — often still positive, but the payoff leans more on rate structure than on PG&E-style sticker shock.
Typical payback in 2026
A well-designed NEM 3.0 solar-plus-battery system in PG&E territory typically pays back in roughly 8–12 years and then produces largely free power for the rest of its life. Cash purchases have the best lifetime returns; loans and leases/PPAs trade some savings for $0 down. The fastest way to see your own number is to run your address and bill through a designer, then get a firm written quote.

How much does solar save in Northern California?
It varies with your usage and roof, but PG&E's high rates mean a right-sized system commonly offsets most of a home's electric bill. The savings come from avoiding expensive grid power, so bigger, higher-rate bills see the largest dollar savings.
Is solar worth it with PG&E's NEM 3.0?
For most PG&E homes, yes. NEM 3.0 lowered the value of exported energy, so the best returns now come from using your own solar and adding a battery for the evening peak. Payback commonly runs 8-12 years.
Do I need a battery for solar to be worth it?
Not strictly, but under NEM 3.0 a battery usually improves the economics and adds outage/PSPS backup. Solar alone still helps if you use a lot of power during daylight hours; a battery captures the value you'd otherwise export cheaply.
