San Leandro solar when the grid is already green
Written by the Solar Learning Lab research deskUpdated August 28, 202611 min read
Most cities sell rooftop solar with a clean energy story. San Leandro took that pitch off the table itself. By a September 2021 council vote, the default electricity supply for homes here is Ava Community Energy's Renewable 100, a 100 percent wind and solar product, effective for residential accounts since March 2022. If your motivation for panels was greener electrons, congratulations, the city already handled it for about a quarter cent per kWh above PG&E, roughly $1 to $2 a month on a typical bill.
So the honest case for solar in San Leandro is not virtue. It is arithmetic against PG&E delivery rates that reach 55 cents per kWh on summer evenings, plus a permitting system that, since May 13, 2024, can issue a residential permit the same day a registered contractor finishes the SolarAPP+ review. This page walks the arithmetic, the permit lane, and the one address trap that catches people who think they live in San Leandro but technically do not.
Check the math before the pitch
Run a screening estimate on your roof size and bill, then make every bidder beat it with specifics.
Estimate San Leandro solarThe premium tier is the default here, and that changes the sales pitch
San Leandro joined what is now Ava Community Energy by council vote in November 2016, and service started in 2018. Then the city went a step further than most Ava members: it made Renewable 100 the default product for residents and businesses, rather than the cheaper Bright Choice tier. CARE, FERA, and Medical Baseline customers are the exception; they default to Bright Choice so the discount lands where it matters. The city takes this seriously enough that Mayor Juan González III sits as Vice Chair of Ava's board.
What does that mean for a solar decision? Two things. First, any installer leading with "get off dirty power" is selling you something you already have. Ask them to move on. Second, the structure of your bill matters more than its label: PG&E still owns the wires, meters, billing, and outage response, while Ava supplies generation. PG&E's own CCA page describes this split, and it is why a San Leandro solar quote has to model two sets of charges, not one.
The rate backdrop is the real motivation. PG&E's bundled residential average price in 2024 was 39.6 cents per kWh per EIA Table 6, and the March 2026 rate sheet prices E-1 at 33 cents to baseline and 41 above it. Renewable 100 sits a quarter cent above PG&E generation pricing, so going solar here is a bet against delivery and generation costs that have not been polite lately.
Instant permits are real since May 2024. Check your address first.
On Monday, May 13, 2024, San Leandro switched on Instant Solar Permits for SolarAPP+ registered contractors. The state's tracking backs this up: the CEC's permitting program dataset shows the city on the SolarAPP+ platform with a 2024 annual report on file and a $60,000 CalAPP grant awarded March 10, 2023. That combination, platform live, report filed, grant spent on automation, is what a working system looks like from the outside, and it satisfies the automated permitting mandate in Government Code 65850.52.
Here is the trap nobody mentions until it bites. Some addresses with San Leandro mailing addresses sit in unincorporated Alameda County, and those homes cannot use the city's instant lane at all. The city's submittal guidelines direct applicants to verify their parcel at GeoSL.org before applying. Thirty seconds on that map beats weeks of confusion when the county quietly becomes your permitting authority with its own separate process.
The instant lane is also gated on the contractor side, and the gates are specific: a CSLB B, C-10, or C-46 license, a current San Leandro business license, SolarAPP+ registration, and no permit runners. Ballasted systems are out. The homeowner has a job too, reviewing and signing the SL Owner SolarAPP Acknowledgement Form before things move. Owner-builders take the standard portal path through SanLeandro.org/PermitPortal instead.
On cost, read the fine print with us. The FY 2026 to 2027 fee schedule lists $464 per residential PV permit up to 15 kW plus $15.45 per kW above that, which sits above the $450 base cap in Government Code 66015. But the schedule's own footnote says total PV permit fees shall not exceed the amounts 66015 authorizes. Both numbers are on the same page of the same document. If a quote passes through permit cost, ask which figure it used.
Exports pay by the hour, and Ava tips the late afternoon
New solar in San Leandro lands under the CPUC's Net Billing Tariff, adopted December 15, 2022 in D.22-12-056 and applicable to interconnection applications from April 15, 2023 onward. Ava layers its own Solar Billing Plan on top: residential participants are required to be on PG&E's E-ELEC rate, exports earn hourly Energy Export Credits, Ava issues the generation side of those credits while PG&E issues the delivery side, and everything trues up each April.
| Energy source | Type | Average price | What that means |
|---|---|---|---|
| PG&E E-ELEC summer | import price by period | 33¢ to 55¢ per kWh | The 4 to 9 p.m. window costs 55¢; midnight to 3 p.m. costs 33¢. Winter runs 28¢ to 32¢. |
| Ava peak export bonus | non-CARE/FERA add-on | 2.5¢ per exported kWh | Paid on exports between 3 and 8 p.m. under the Solar Billing Plan. |
| State export bonus, 2026 interconnection | ACC Plus style adder | 0.9¢ / 3.6¢ per kWh, standard / income qualified | Locked nine years from interconnection; 2027 drops to 0.4¢ and 1.8¢. |
| Self-consumed solar | avoided retail purchase | up to the E-ELEC rate in effect not a tariff line | A kWh used in the house during the 55¢ window is worth many times an exported one. |
PG&E's March 2026 residential rate sheet and Ava's Solar Billing Plan page. Snapshot values, not a bill forecast.
Notice what this structure rewards. Exports at noon earn modest hourly credits. Exports from 3 to 8 p.m. pick up Ava's 2.5 cent bonus. Consumption avoided during the 4 to 9 p.m. E-ELEC peak is worth up to 55 cents. The design pushes toward batteries and load shifting, not toward the biggest possible array. CARE and FERA households get a different mix: a 1 cent Ava export bonus plus a 3.6 cent state bonus at 2026 interconnection, per Ava's published tables. The nine-year lock on the state bonus also means a 2026 interconnection keeps 0.9 cents while a 2027 one keeps 0.4, a real if small reason not to drift into next year.
Bay-side production: solid, with a fog haircut
Our PVGIS model puts a downtown San Leandro roof at 1,602.9 kWh per year for each installed kilowatt. July peaks at 168.3 kWh per kW and December bottoms at 85.5. That is respectable output, though the marine layer keeps it below what the same panels would do over the hills in the Tri-Valley. The summer months hold a long, flat plateau rather than a single spike, which suits steady household loads.
July models at 168.3 kWh per kW. May through August all land within about 5 kWh of each other, a plateau rather than a peak.
PVGIS v5.2 model run by Solar Learning Lab on August 28, 2026, NSRDB radiation database. Fixed south facing mount, 30 degree tilt, 14 percent losses, downtown San Leandro coordinates. Your roof will differ. The run comes from the PVGIS tool. It compares locations under identical assumptions; it does not know your roof pitch, your neighbor's redwood, or your panel brand. A serious proposal reconciles this baseline against a shade study and your last twelve bills.
One structural note on the local housing base: the state's 2026 E-5 estimates count 19,797 single detached homes among 33,550 total units, 59 percent, much of it postwar tract housing from the decade when the city grew 139.5 percent. Those roofs are simple and often unshaded, but many carry original framing that a mounting plan has to respect.
What help still exists after the federal credit died
Clear the big one first: the 30 percent federal homeowner credit under 25D terminated for expenditures after December 31, 2025, and the law treats an expenditure as made when installation is completed, so a system finished in 2026 gets nothing. The Congressional Research Service note spells it out. Carryforwards from pre-2026 installs survive. Any San Leandro quote that still whispers "30 percent back" is describing a dead program.
What remains is targeted. SGIP's Residential Solar and Storage Equity budget, $280 million with reservations open since June 2, 2025, pays $3,100 per kW of solar and $1,100 per kWh of storage for income-qualified households. DAC-SASH through GRID Alternatives runs through 2030 and requires a top 25 percent CalEnviroScreen tract plus CARE or FERA income; San Leandro homes clear its utility territory test because they are PG&E billed. And the property tax new construction exclusion for active solar systems runs through the 2025 to 2026 fiscal year before sunsetting January 1, 2027.
If an HOA governs your roof, Civil Code 714 is your leverage: restrictions that add over $1,000 of cost or cut efficiency more than 10 percent are void, denials must be in writing, and an application not denied in writing within 45 days is deemed approved absent a reasonable information request.
The local bid pool leans on neighboring towns
Our Google Maps pull for San Leandro surfaced a short bench, and part of it is adjacent: Castro Valley and Oakland firms serving the city, plus a distribution branch that does not install at all. Nothing wrong with a Castro Valley crew on a San Leandro roof, but remember the instant permit lane requires a San Leandro business license, so ask each bidder directly whether they hold one and whether they are SolarAPP+ registered here. A yes to both is the difference between a same-day permit and the standard queue.

Screen the project, then stress it
This estimator uses the state retail rate and our local production run. It cannot model hourly export credits or Ava bonuses, so its output will flatter an export-heavy design and shortchange a battery. Use it to bracket system size and payment method, then demand an hourly model from whoever wants your signature.
The upper bound is our San Leandro PVGIS run at the downtown coordinates. The lower bound is 85 percent of that, a sanity margin for a cooler, foggier, or partly shaded roof plane.

The federal homeowner credit under 25D ended for installs completed after December 31, 2025, so a third party ownership pitch in 2026 rests entirely on whether the offered rate beats your combined PG&E and Ava bill. Compare against twelve real statements.
