Solar in Fremont: the permit office acts like it has seen solar before

Fremont has spent more than a decade making solar ordinary

The City's solar posture is not a recent marketing campaign. Fremont adopted its Renewable Energy Ordinance in 2012, reduced residential solar permit fees and set streamlined processing rules. The solar ordinance limits permit turnaround for small rooftop systems to three days. In 2024, Fremont became SolSmart Platinum after previously holding Gold with a Special Award for Excellence in Permitting. The City's solar page calls it the first community in the country to reach that Platinum level.

Numbers show what an established local process can compound into. Fremont reports solar permits rising from 777 in 2020 to 1,010 in 2021 and 1,188 in 2022. By the end of 2023, it counted 9,801 residential and 161 commercial or industrial sites with PV, totaling 67 MW of PV plus 5.47 MW of storage. That does not make a particular roof good. It does mean the City's counter staff, inspection process and local electrical trade are operating in a place where this work is normal. Fremont's adoption data.

There is a useful contrast with interior Central Valley markets. Fremont's nearest long-term station, Hayward Air Terminal, shows 1,651.2 cooling degree days at base 57 and a 59.6 F annual mean. The summer load can still be substantial, but the solar case leans more heavily on high retail power prices and careful load timing than on relentless air-conditioning use. NOAA's nearby climate normals provide the weather context.

The housing inventory is more mixed than a drive through a single-family neighborhood might suggest. State estimates count 44,999 single-detached homes out of 82,658 housing units, while 23,423 units are in buildings with five or more homes. That means a lot of Fremont households will not control a roof. For owner-occupied detached homes, however, an institutional permit process removes one of the variables that is often a headache elsewhere. California's E-5 housing data is the source for that mix.

Renewable 100 is the Fremont default. PG&E still bills the account.

Fremont City Council voted in June 2024 to make Ava's Renewable 100 the default generation plan. The residential transition finished in August 2025. Renewable 100 is described as 100 percent renewable and priced at 1.75 cents per kWh above PG&E generation. CARE, FERA and Medical Baseline customers default to Bright Choice instead. Ava supplies generation; PG&E handles delivery and billing. Ava's Fremont page and the City announcement spell out the transition.

For a new PG&E interconnection, exports are governed by the CPUC Net Billing Tariff, branded by PG&E as the Solar Billing Plan. This page will not replay the generic statewide explainer. The Fremont-relevant point is operational: onsite generation serves onsite load, exports receive hourly energy export credits, credits roll through monthly billing to annual true-up, and residential Solar Billing Plan customers are placed on E-ELEC. PG&E lists a $145 interconnection fee. PG&E's program page and the CPUC overview carry the current formal terms.

Ava publishes a 2026 standard residential Energy Export Bonus Credit of 0.9 cents per kWh for nine years, with a 3.6-cent figure for eligible income-qualified customers. It also lists a 1-cent export bonus for CARE and FERA customers and a 2.5-cent bonus for non-CARE and non-FERA exports from 3 to 8 p.m. These can improve a well-designed system. They are not a substitute for load matching or a reason to treat every exported noon kWh as a retail kWh. Ava's Solar Billing Plan page has the eligibility details.

Here, storage fits inside the fast permit instead of fighting it

Fremont's ISP includes roof-mounted PV with or without energy storage. That is a significant local distinction. A homeowner can examine solar plus a battery, and potentially a service upgrade, within the same streamlined record if the project meets the system's requirements. Stacked storage needs the UL 9540 report, but the City has already decided that storage belongs in the solar workflow. ISP requirements.

Ava's SmartHome Battery program launched April 9, 2026 with an $11 million budget. It offers a $90 per kWh installation rebate for market-rate customers and $500 per kWh for income-qualified customers on the share enrolled in its virtual power plant, plus $3 per month per shared kWh. Customers choose a 40, 60 or 80 percent share and must own the battery. The program is first-come, first-served until the budget is committed. Ava's announcement is the document to use for current terms.

That program should not be confused with a universal battery discount. Ownership, program compatibility and enrollment share matter. Ava's prior Resilient Home program is closed to new enrollment, though it created a virtual power plant with more than 1,200 homes. Ava's Resilient Home page tells new customers to look to the 2026 offering instead.

There is also SGIP for qualifying storage projects in PG&E territory. The CPUC lists Equity incentives of $850 per kWh and Equity Resiliency incentives of $1,000 per kWh for qualifying conditions, with priority categories that include high fire-threat exposure, multiple PSPS events, low income, medical vulnerability and critical facilities. This is not a standard rebate. Ask for eligibility evidence before it appears in a net price. CPUC SGIP information.

The homeowner 25D credit ended December 31, 2025. A lease or PPA provider may claim 48E. That makes the financing form more consequential, not less. Congressional Research Service IN12611 is the policy reference. Evaluate a battery for backup, self-consumption, the Ava program and contract economics. Do not use an expired personal credit as a reason to rush.

Use the Fremont calculator to set questions, not to replace a bill model

This calculator combines the local PVGIS output with California cost and retail-rate context. It cannot reproduce the hour-by-hour energy export credits, Ava's bonuses, the base service charge or your roof's shade. It is useful for seeing system scale and finance assumptions move. Then take the resulting size to a contractor and request the missing hourly logic.
