Solar and Battery in the Bay Area: Is It Still Worth It in 2026?
The federal tax credit expired, PG&E rates keep climbing, and California's battery rebate is still active. Here's a straight, local look at what actually matters this year.
If you've been putting off going solar, 2026 is the year to run the real numbers — because several things changed at once. The federal residential solar tax credit expired at the end of 2025, PG&E rates keep climbing, and California's battery rebate program (SGIP) is still active for many homeowners. Here's a straight, local look at what actually matters this year, from a Bay Area installer who's completed over 1,000 systems.
The big change: the federal tax credit expired December 31, 2025
For years, the 30% federal residential solar tax credit was the headline incentive. As of January 1, 2026, that credit is no longer available for homeowner-owned residential solar. That's a real change, and any installer who tells you otherwise isn't being straight with you.
But "the tax credit is gone" doesn't mean "solar stopped making sense." It means the math changed, and the other levers — rebates, financing structures, and rising utility rates — now carry more weight.
With a prepaid power-purchase arrangement, a third party owns the system and captures the incentives a homeowner can no longer claim directly — then transfers ownership to you down the road. We offer the HDM Prepaid PPA for exactly this reason: HDM owns the system and captures the tax credit, you get the solar with no production guarantee gimmicks, and ownership transfers to you at Year 6 at no additional cost (and it's transferable if you sell the home). For many homeowners, it's the cleanest way to keep solar economics working now that the direct credit is gone. Whether it fits you depends on your situation — worth a conversation, not a blanket answer.
PG&E rates are the real story
Here's what drives most Bay Area solar decisions in 2026: your utility bill keeps rising. PG&E rates have climbed steadily and are widely expected to keep increasing over the coming years. Every year you wait is another year of paying those rates in full.
Solar's value has always been about offsetting what you'd otherwise pay PG&E. As those rates rise, the value of each kilowatt-hour your panels produce rises with them. That dynamic hasn't changed — if anything, it's stronger now.
Batteries: where SGIP still helps
This is the part many homeowners miss. California's Self-Generation Incentive Program (SGIP) offers rebates on home battery storage, and for qualifying customers those rebates can be substantial. Higher incentive tiers exist for homes in high-fire-threat districts or on medical baseline, but general-market rebates are available too.
A home battery — Tesla Powerwall, FranklinWH, or Enphase IQ — does two things that matter in the Bay Area:
- Backup power during outages. When the grid goes down during PSPS events or storms, your critical circuits keep running.
- Rate optimization under NEM 3.0. Under California's current net-metering rules, exporting solar to the grid is worth far less than it used to be. A battery lets you store your own daytime solar and use it in the evening instead of selling it back cheaply — which is how you protect your savings under the new rules.
If you're on NEM 1.0 or NEM 2.0, there are specific ways to add a battery without losing your grandfathered net-metering status — including non-export configurations. Doing it wrong can cost you that favorable rate, so it's worth working with an installer who understands the interconnection rules.
The panels matter more than ever
With the tax credit gone, the long-term quality of your system carries more weight — you want equipment that keeps producing for decades, not something that saves a few dollars up front and underperforms later. That's why we install REC panels, and why we're a REC Certified Solar Professional.
Because we're REC-certified, your system can carry REC's 25-year ProTrust warranty covering all three things that matter: the product, the labor, and the performance. Most warranties cover the panel alone — this covers the whole package, backed by both REC and us as your local installer. Over a 25-year system life, that's the kind of protection that actually matters when something needs attention years from now.
What a system actually costs in 2026
Honest answer: it depends on your roof, your usage, and whether you're adding a battery. Rather than quote a misleading "average," here's how to think about it:
- Solar alone offsets your electricity usage and pays back over time through avoided PG&E charges.
- Solar + battery adds backup power and NEM 3.0 optimization, with SGIP helping offset the battery cost for those who qualify.
- Battery-only, added to existing solar or standalone, can make sense if backup power is your main goal.
The right size isn't the biggest system — it's the one matched to your actual energy use and goals. A good installer will pull your usage history and design to it, not upsell you.
What to actually do in 2026
- Look at your PG&E bill. If it's high and rising, solar's value proposition is strong regardless of the federal credit change.
- Check SGIP eligibility for a battery. The rebate can meaningfully change the battery math.
- If you have old solar, protect your NEM status before adding anything.

Why local matters here
Bay Area solar isn't generic. Permitting differs city to city, our fire-threat maps affect SGIP tiers, PG&E's interconnection process has its own quirks, and NEM rules reward local expertise. Ally Electric & Solar has installed over 1,000 systems across the Bay Area — Berkeley, Oakland, Richmond, Orinda, Walnut Creek, the Peninsula, and beyond. As a REC Certified Solar Professional offering the HDM Prepaid PPA, we handle the design, permitting, and interconnection so you don't have to — and we help you find the path that still makes solar pay off in 2026.
