Solar for your Northern California home

An honest, no-pressure read on whether solar — and a battery — makes sense for your home: the real savings, backup power for outages, and which incentives actually apply to you.

The Northern California solar build-out — press play
Service areaUtility-scale plants (build-out above)
Utility-scale solar across California, appearing by the year each plant came online (dated sites from OpenStreetMap + EIA). Shaded = the 40-county region we serve; toggle the 39,121 rooftop & distributed arrays above. Wondering what your roof could do? Try the Rooftop Designer.
Why solar makes sense here
Among the nation’s highest power bills
PG&E rates keep climbing, so every kilowatt-hour your panels make pays back faster here.
NEM 3.0 makes batteries pay
Exported power earns far less now — a battery lets you use your own solar at night.
Backup for PSPS & wildfire season
A home battery keeps your lights, fridge and Wi-Fi running when the grid goes down.
Incentives, honestly (2026)
The 30% federal buyer credit ended after 2025; SGIP and lease/PPA options may still help.
What today’s rules mean
NEM 3.0 — net billing
Since April 2023, PG&E credits exported solar far below the old NEM 2.0 — so the value is in using your own power, ideally with a battery.
Federal tax credit — ended for buyers
The 30% residential credit ended after 2025 for homeowners who buy; a lease/PPA can still use the federal business credit through 2027.
California SGIP — battery rebate
Can help fund a battery — mainly for wildfire/PSPS, medical-baseline and lower-income homes.
Programs change and depend on your home & utility — a specialist confirms what applies to you. Not financial or tax advice.

Northern California solar FAQ
Is solar still worth it in Northern California under NEM 3.0?

For many homes, yes. PG&E's rates are among the highest in the country, so the solar you use directly still saves a lot. Under NEM 3.0 the power you export earns less, so the strongest setup pairs panels with a battery, so you use your own energy in the evening instead of selling it back cheaply.

Do I need a battery?

It isn't required, but under NEM 3.0 a battery is usually where the value is. It stores daytime solar for evening use and keeps essentials running during PG&E Public Safety Power Shutoffs (PSPS) and other outages.

What happened to the 30% federal solar tax credit?

For homeowners who buy a system, the 30% federal residential tax credit ended after 2025. A lease or power-purchase agreement (PPA) can still use the federal business credit through 2027, and California's SGIP program may help fund a battery for eligible homes. A specialist can confirm what applies to you.

What is NEM 3.0 / net billing?

NEM 3.0 is PG&E's Net Billing Tariff, in effect since April 2023. It credits the solar power you export to the grid at a much lower rate than the old NEM 2.0 - which is why using your own solar, ideally with a battery, matters more now.

Will solar keep my power on during a PSPS or outage?

Only if you have a battery (or a hybrid system designed for backup). For safety, standard grid-tied solar shuts off during an outage; a battery is what keeps your lights, fridge and Wi-Fi running.

Am I in PG&E territory?

Most of Northern and Central California is served by PG&E, but some cities run their own municipal utilities (for example SMUD in Sacramento, plus Redding, Roseville, Santa Clara, Palo Alto, Modesto, Turlock, Alameda and Lodi). See the PG&E territory map above.

How much does solar cost?

It depends on your roof, your usage, and whether you add a battery. Use the Rooftop Designer for a ballpark estimate from your address, and a licensed installer for a firm quote.

Are you a solar installer?

No. Golden State Solar Guide is an independent information resource. We help Northern California homeowners understand their options and connect with local professionals - we don't sell or install systems ourselves.
