Your Berkeley Electricity Bill
Most Berkeley residents get electricity from two providers: PG&E handles delivery (wires and meter), while Ava Community Energy provides the generation. Berkeley helped found Ava in 2016, and accounts have been automatically enrolled since 2018.
Your bill breakdown: PG&E delivery charges + Ava (or PG&E, if opted out) generation charges. Solar export credits and interconnection are tied to PG&E tariffs.
Berkeley accounts are automatically enrolled in Ava Renewable 100. You can switch Ava plans or opt out to PG&E bundled service. Our calculator defaults to Ava customer settings for Berkeley addresses.

Frequently Asked Questions
How much does solar cost in Berkeley?
The average residential solar installation in Berkeley costs $2.10–$3.20 per watt (source: CA Energy Commission and local installer data). A typical 7.5 kW system runs $15,900–$24,200. Note: The 30% federal tax credit expired on Dec 31, 2025 and is no longer available for new installations.
What incentives are available for Berkeley homeowners?
The 30% federal tax credit (IRC §25D) expired Dec 31, 2025. Current incentives include Ava Community Energy export bonuses (source: Ava SBP page), SGIP battery rebates (source: PG&E/CPUC), the ACC Plus export adder locked for 9 years if you interconnect before end of 2027 (source: PG&E Net Billing tariff), and California's property tax exclusion for solar through Jan 1, 2027 (source: CA Board of Equalization).
What is the Solar Billing Plan and how does it affect my savings?
The Solar Billing Plan (also called Net Billing Tariff, sometimes referred to as "NEM 3.0") replaced NEM 2.0 for new solar interconnections since April 15, 2023 (source: CPUC Decision 22-12-056). Export credits are time-varying based on when your energy hits the grid, averaging around $0.04–$0.09/kWh during solar production hours. Customers who interconnect before end of 2027 receive a slightly higher export credit via the ACC Plus adder (also called "Energy Export Bonus Credit"), locked in for 9 years from PTO (source: PG&E Electric Rule 21/Net Billing tariff). Battery storage and self-consumption are key to maximizing savings under this plan.
Do I need a permit for solar panels in Berkeley?
Yes. All solar PV installations require an electrical permit. Building permits are only needed if structural work is necessary to support the system (source: City of Berkeley PV Submittal Requirements). Berkeley offers a streamlined online permitting process for most residential PV installations. Systems with battery storage may require additional documentation and inspection steps.
Is battery storage worth it in Berkeley?
Battery storage is increasingly valuable under the Solar Billing Plan because it lets you store solar energy and use it during expensive peak hours (4–9 PM on E-ELEC) instead of exporting at lower credit rates. Batteries also provide backup power during PSPS events and grid outages. Note: batteries may need mid-life replacement (typically after 10–15 years), which should be factored into long-term economics.
What is Ava Community Energy?
Ava Community Energy (formerly East Bay Community Energy) is Berkeley's Community Choice Aggregation (CCA) provider. Berkeley helped found Ava in 2016 and has used Ava electricity since 2018. Berkeley accounts are automatically enrolled in Ava Renewable 100. Your bill has two main parts: PG&E delivery (wires) + Ava generation. Ava provides additional export bonuses for solar customers on top of standard Solar Billing Plan credits (source: Ava Community Energy SBP page).
What happens to my extra solar credits?
Under the Solar Billing Plan, you receive monthly statements and an annual true-up (typically in April). Remaining credits roll over month to month. At true-up, surplus kWh are paid out at the Net Surplus Compensation rate. If the cash-out value is under $100, it stays as a bill credit; $100 or more results in a check (typically June–July after the April true-up).
How long does solar installation take in Berkeley?
The physical installation typically takes 1–3 days. However, the full process from contract signing to Permission to Operate (PTO) usually takes 8–16 weeks, including permit review (1–2 weeks), installation (1–3 days), city inspection (1–2 weeks), and PG&E interconnection (4–8 weeks).
What happens during a power outage if I have solar?
Solar panels alone will shut off during a grid outage for safety reasons (anti-islanding). To keep power during outages, you need a battery storage system with backup capability. A typical 13.5 kWh battery can power essential loads for 8–12 hours.
Can I get solar at very low cost if I qualify?
Yes. The DAC-SASH program (Disadvantaged Communities – Single-family Affordable Solar Homes) enables income-qualified homeowners in disadvantaged communities to receive no-cost rooftop solar, administered by GRID Alternatives (source: CPUC/GRID Alternatives). Contact GRID Alternatives to see if you qualify.
