Solar & Battery Backup Installation in San Marino, CA
Southern California Edison's Net Billing Tariff has cut what you earn for exported solar power, and San Marino's strict Design Review process is the other thing that trips up local solar projects. AWS Solar has installed and serviced systems across the San Gabriel Valley, and we handle the Design Review submission and SCE interconnection paperwork so your project moves rather than stalls.

We're a local installer, not a national telemarketing outfit — the crew that designs your system is the same crew on your roof, and the same one who answers if you ever need a service call. We handle SCE interconnection paperwork, City of San Marino permitting, and Design Review submissions in-house, so you're not the one chasing multiple offices.
What SCE's Net Billing Tariff (NEM 3.0) Means for Your Payback
San Marino is served by Southern California Edison, and since April 2023 new solar customers are placed on the Net Billing Tariff (NBT), not the older NEM 2.0 program. Under NBT, the credit for exporting surplus power to the grid is set by a formula that changes month to month and averages far below the retail rate you pay to pull power back at night. Signing up in 2026 locks you into the "NBT26" export-rate vintage for 9 years.
That's exactly why we size most San Marino systems around battery storage rather than maximizing panel count for export. A Tesla Powerwall 3 lets you store your own midday solar production and use it in the evening instead of selling it to SCE for a few cents and buying it back for over 40 cents — and it keeps your home powered if SCE calls a Public Safety Power Shutoff or your area loses power for any other reason.
San Marino's Design Review Process — Handled, Not Just Explained
San Marino doesn't have private neighborhood HOAs the way Calabasas does, but its City Design Review process serves much the same function: exterior changes, including solar and battery equipment, go through Design Review before a building permit is issued. In practice that means requirements similar to what HOAs impose elsewhere — black-frame, low-profile panels instead of silver-frame, and conduit runs painted to match your roofline and stucco — reviewed and approved by the City rather than a private board. Once Design Review signs off, San Marino moves solar and battery permits through an expedited track, so the city side of the process is usually the fast part.

San Marino Solar & Battery FAQ
Is San Marino served by SCE or a different utility?
Southern California Edison (SCE) serves San Marino and the surrounding San Gabriel Valley. That means your system is designed around SCE's Net Billing Tariff export rates and interconnection process, not NEM 2.0 or a municipal utility program.
Will I need approval before installing solar?
San Marino doesn't have private HOAs like some of the cities we serve, but it does require City Design Review approval for exterior work, including solar and battery equipment, before a building permit is issued. California's Solar Rights Act limits how restrictive that review can be, but the City can still set reasonable conditions on panel color and conduit placement. We handle that submission for you, and Design Review approval has to be in hand before we submit for your building permit.
Does a battery make sense if I'm mainly trying to lower my SCE bill?
Under the current Net Billing Tariff, yes — a Powerwall 3 lets you use your own solar production at night instead of exporting it for a low credit and buying it back at SCE's full retail rate, which is usually the bigger lever on your bill than panel count alone.
How long does permitting take with the City of San Marino?
Once your Design Review package is approved, San Marino moves solar and battery permits through an expedited review, so the city side is usually fast. Design Review is the variable step — we'll give you a realistic estimate once we've scoped your specific property rather than a generic number.
