Going solar in Palo Alto comes with a twist most Bay Area guides miss: Palo Alto isn't on PG&E — it's served by the City of Palo Alto Utilities (CPAU), which has its own rates, its own net-metering rules, and its own solar permitting. Add in the city's older housing stock and frequent underground utilities, and a Palo Alto solar project has a few local wrinkles worth understanding before you sign. Here's the local homeowner's guide.
Pacific Edge Electric and Solar is a licensed C-10 electrical contractor (CA #1143455). We install solar and do electrical work throughout Palo Alto and the mid-Peninsula, so this is grounded in the local realities — not a generic PG&E script.
The CPAU difference
Because Palo Alto runs its own municipal utility, the solar economics work differently than in most of the county:
- Different rates. CPAU's electric rates and structure aren't PG&E's, so your savings math is specific to Palo Alto — don't assume a PG&E-based estimate applies.
- Different net-metering rules. California's statewide NEM 3.0 applies to PG&E and the other big investor-owned utilities; a municipal utility like CPAU sets its own solar/export policy. That changes how a battery pencils out here, so the design should be built around CPAU's actual rules.
- Local permitting and interconnection. Your solar permit and interconnection go through the City of Palo Alto, not PG&E — a process a local installer already knows.
The takeaway: a trustworthy Palo Alto solar quote is modeled on CPAU rates and rules, not copied from a PG&E template.
Palo Alto's older homes: plan the electrical first
A lot of Palo Alto's charm is in its older homes — Professorville, Old Palo Alto, Crescent Park — and older homes often mean older electrical. Before (or with) solar, we frequently find:
- Undersized service (100A) that needs upgrading to comfortably add solar, a battery, and an EV charger.
- Aging panels (including Zinsco/Federal Pacific in some vintages) that should be replaced as part of the project.
- Older wiring that's worth evaluating while the electrician is on site.
Because we're electricians and solar installers, we handle the panel upgrade and the solar as one coordinated job — one permit set, one crew — which matters more here than in a subdivision of newer homes.
What solar costs in Palo Alto
Installed pricing tracks the broader Bay Area — roughly $20,000–$50,000 for a residential system ($2.50–$3.80/watt), plus $9,000–$20,000 for a battery — but if an older home needs a service upgrade first, budget that in ($4,500–$14,000). Note the 30% federal residential tax credit expired after 2025, so 2026 projects use full pricing; the case still holds on high electric costs and self-consumption. See our transparent pricing.
Should Palo Alto homes add a battery?
It depends on CPAU's export/net-metering rules — which is exactly why the design should start from the local utility terms. In general, storage still adds resilience (Peninsula outages happen) and lets you use your own power in expensive hours, but the payback specifics are Palo-Alto-specific. We model it on CPAU's actual rates so you're deciding on real numbers.
Work with a local team
The single biggest mistake we see in Palo Alto is a homeowner accepting a national installer's quote built on PG&E assumptions that simply don't apply. Get a design modeled on CPAU, done by a crew that knows the city's permitting and its older homes. See our Palo Alto electrician & solar services or request a free Palo Alto assessment.
Frequently asked questions
Is Palo Alto on PG&E?
No. Palo Alto is served by the City of Palo Alto Utilities (CPAU), a municipal utility with its own electric rates, net-metering/export rules, and solar permitting. That makes Palo Alto solar economics different from PG&E areas, so quotes should be modeled on CPAU specifically.
Does NEM 3.0 apply in Palo Alto?
California's statewide NEM 3.0 applies to the big investor-owned utilities like PG&E. As a municipal utility, CPAU sets its own solar export policy, so your battery and savings math should be based on CPAU's rules, not PG&E's NEM 3.0.
How much does solar cost in Palo Alto?
Similar to the wider Bay Area — about $20,000–$50,000 for a residential system plus $9,000–$20,000 for a battery — but older Palo Alto homes may also need a $4,500–$14,000 panel or service upgrade first.
Do older Palo Alto homes need electrical work before solar?
Often. Many older homes have 100A service, aging panels, or dated wiring that should be upgraded to support solar, a battery, and EV charging. Doing the electrical and solar as one coordinated project is usually cheaper and cleaner.
Utility rates and net-metering rules change; confirm current CPAU terms during design. Ranges are typical planning figures quoted in writing before work begins. Written by Adam Aksoy, licensed C-10 electrical contractor (CA #1143455), Pacific Edge Electric and Solar.
