Berkeley solar runs through Ava's rules, not MCE's

Written by the Solar Learning Lab research deskUpdated August 24, 20269 min read

The obvious mistake in Berkeley is carrying an MCE explanation across the Bay. Berkeley's community-choice provider is Ava Community Energy. Ava has its own NEM policy, its own true-up choices, and its own treatment for standard, legacy municipal, and CARE/FERA customers.

The permitting side is disciplined too. Eligible systems of 10 kW AC or less on a single-family home or duplex receive real-time SolarAPP+ approval. Standard solar permit applications are reviewed within one working day. Those are different paths with different fees, not interchangeable marketing lines.

Identify the Ava and permit category first

A Berkeley proposal should name the applicable Ava policy category and whether the system has the real-time approval route.

Ava Community Energy is the local generation provider

Ava lists Berkeley as an original jurisdiction, with service beginning in 2018. The organization reports 55,100 total Berkeley accounts and 5,900 solar accounts. PG&E remains the delivery utility, but the generation-side solar policy belongs to Ava, not MCE. Ava's Berkeley page.

The distinction is not cosmetic. Ava's published NEM policy follows PG&E Electric Schedule NEM structure, but provides its own category terms and true-up choices. Read the tariff document named in the actual account conversation, not a nearby city's CCA summary. Ava NEM policy.

Real-time approval has a defined boundary

Berkeley uses SolarAPP+ for eligible systems at 10 kW AC or smaller on single-family or duplex properties. Qualifying submissions receive real-time approval. Systems that do not use that route are not left in a mystery queue: the city says standard solar applications are reviewed within one working day. Berkeley's solar-permit page.

That range matters in a city with a lower single-family share than the other cities in this set. A building type can shape the route as much as panel size. Do not advertise the fastest pathway until the property and system meet the city's stated criteria.

Berkeley publishes several distinct solar line items

The fee schedule lists $100 per system for residential SolarAPP+, $200 for residential solar at 15 kW or less including plan check, and $250 plus $15 per kW above 15 kW for the larger residential category. It also lists a $62.50 filing fee, $150 electrical-permit base fee, and a 5 percent technology enhancement fee on specified permit categories. Berkeley's fee schedule is the place to calculate actual scope, not a single headline number.

The $200 small-system line and $250 plus $15 per kW larger line remain within the $450 plus $15 per kW state baseline. The large-system per-kW adder matches the statute's stated $15 amount. Government Code 66015.

Ava gives standard customers a settlement choice

Under Ava's policy, standard NEM customers may choose monthly or annual true-up. The default is monthly; the election must be made before March 1 to take effect with the following April billing cycle, and the policy says it can be changed once each year. CARE/FERA and Legacy Municipal customers use monthly true-up. Policy details.

Energy source	Type	Average price	What that means
Ava Standard NEM	monthly export bill credit	retail rate per kWh exported	The policy differentiates monthly credit from annual surplus payout.
Ava Legacy Municipal	monthly export bill credit	retail + $0.01 per kWh	This category has distinct legacy treatment.
Ava annual payout	standard customer	PG&E NSC per kWh	Legacy Municipal and CARE/FERA have a different stated payout rule.
Solar used behind the meter	direct self-use	retail avoided cost depends on usage	It avoids a contemporaneous purchase instead of waiting for surplus settlement.

Ava NEM policy and PG&E pricing sheet.

Annual cash-out happens in April, and balances over $100 are paid by check under the policy. That may be useful cash-flow detail, but it is not an argument to design around surplus production.

Berkeley is cooler, wetter, and still productive

The downtown PVGIS run estimates 1,599.3 kWh per installed kW annually. May is narrowly the high month at 162.9 kWh per kW, and December is 87.5. This is the lowest annual output in this five-city group, which makes a conservative design assumption more useful than a sunny-state slogan.

The Ava battery program is structured, not a flat coupon

Ava's SmartHome Battery rebate depends on household income, battery size, and shared virtual-power-plant capacity. Participants can receive quarterly payments for five years for sharing capacity. There is no single fixed rebate amount published for every home, so an installer should not turn the program into a universal dollar claim. Ava SmartHome Battery.

The homeowner 25D tax credit ended after 2025 under the federal change described by CRS. Existing eligible unused credits can carry forward, but that does not make a newly completed 2026 owner purchase eligible. Federal credit context.

Ask installers which Berkeley lane the design fits

The core questions are concrete: Is the property a single-family home or duplex? Is the system 10 kW AC or less? Is the proposal using SolarAPP+? Is the Ava customer on monthly or annual true-up? Get those answers before equipment-brand talk.

This is a retail-rate screening estimate. Ava's NEM policy has monthly and annual true-up choices, so a real proposal should make its self-use and settlement assumptions visible.

Solar loan

In Berkeley, compare loan economics only after the permit path and property type are clear. A standard permit and an eligible SolarAPP+ project are not the same workflow.

Lease / PPA

$0 down you buy the power

Year 1 net: $44/mo
Upfront: $0
20 year net position: $14,535

A PPA price needs to compete with the utility bill and Ava policy, not with a promise that every solar kWh has the same value.
