We're a Tesla Certified Installer, and our own C-10 crew installs Powerwall 3, FranklinWH, Enphase IQ batteries and Generac generators across Santa Cruz County. Two things changed before you shop: NEM 3.0 cut what PG&E credits for exported solar, and the federal Section 25D credit expired at the end of 2025. The math still works, and for most homes that now means solar plus a battery, but it works differently than older sales pitches suggest.
(1) NEM 3.0 (the Net Billing Tariff). Since April 2023, California credits exported solar at the utility's "avoided cost" rate — about $0.05–$0.08/kWh, against the roughly $0.42/kWh retail rate, and about 75% less than the old NEM 2.0 export credit. That pushed solar-only payback out considerably. Solar + battery still pays off, because the battery lets you self-consume your own production at the retail rate you'd otherwise be paying, instead of exporting at the much lower credit.
(2) Federal Section 25D expired December 31, 2025. The 30% residential federal tax credit on owned solar PV and standalone battery storage that was the headline incentive for nearly two decades was terminated by the One Big Beautiful Bill Act (OBBBA, 2025). For 2026 installs of owned systems, the credit no longer applies. Third-party-owned / leased systems technically still benefit via the installer's commercial credit pass-through, but we don't sell those and we don't recommend them. GoGreen Home financing is unchanged. SGIP, the state battery rebate, closed its general budgets to new applications at the end of 2025, and in PG&E territory its income-qualified rebate is waitlist-only.
We don't sell standalone solar in 2026 — the NEM 3.0 math doesn't work for most homes without a battery. If you want solar, plan for solar + battery, or come back with an existing battery in place. We sell owned systems only (cash or GoGreen financing), and we model the owned-system math honestly at the consultation: PG&E avoidance over time, historical rate escalation, self-consumption with and without battery.
Whole-home backup is its own conversation. PSPS shutdowns are routine in the San Lorenzo Valley (Felton, Boulder Creek, Ben Lomond) and in the foothills above Scotts Valley. Whole-home propane generators with automatic transfer switches are still the most common choice — runs everything continuously, refuels easily, well-understood technology. Battery storage is quieter, lower-maintenance, lower-emissions, and pairs with solar for peak-shift savings on top of backup.
We install Tesla Powerwall 3, FranklinWH aPower 2, Enphase IQ Battery 10C, and Generac PWRcell. Brand decision depends on your daily home usage, your existing solar (or planned solar), and how long your typical PSPS lasts.
