Despite rumors following the CPUC's adoption of NEM 3.0 in April 2023, going solar in California remains one of the highest-yield financial moves for homeowners. The only difference is the equipment configuration: solar must now be installed alongside battery storage to capture maximum economic value.

Frequently Asked Questions
Is solar still worth it in California after NEM 3.0? ▼
Yes, absolutely—provided you include battery storage. A properly paired solar + battery system yields a 14% to 22% internal rate of return (IRR), with typical system payback achieved in 5.5 to 7 years against utility rates rising 8-12% annually.
What is the 25-year financial savings of going solar in Southern California? ▼
For an average homeowner currently paying $400/month for electricity, a 25-year cumulative utility forecast with 7% annual inflation totals over $300,000. An owned solar + battery system costs approximately $22,000 net, saving over $270,000 in direct cash.
How does the 30% Federal Solar Tax Credit work? ▼
Section 25D of the Internal Revenue Code provides a direct dollar-for-dollar tax credit equal to 30% of the total installation cost for solar panels, battery storage, and necessary electrical panel upgrades with no dollar cap.
Does solar increase home property value in California? ▼
Yes. According to Zillow and Berkeley Lab studies, homes with owned solar and battery storage in California sell for an average of 4.1% more and spend fewer days on the market than non-solar homes, and California law exempts solar systems from property tax reassessment.
Should I buy or lease solar panels in 2026? ▼
Direct ownership (cash or low-interest solar financing) offers the highest financial return, full 30% tax credit capture, increased home equity, and freedom from third-party contract transfer headaches when selling your home. AD Solar specializes in direct ownership solutions.
