START IN 2026. ACTIVATE IN 2027
2026: The Year of the 1-2 Year ROI
For a limited time, two powerful incentives overlap to cover up to 80% of your system costs:
40% Investment Tax Credit (ITC): Start by October 2026 and activate by the end of 2027.
100% Bonus Depreciation: Now permanent, allowing you to expense the full cost in Year 1.
Credit timeline applies to SCE, SDG&E & PG&E territories.
LADWP customers still qualify for full Bonus Depreciation and battery credits.
LEARN ABOUT THIS GOLDEN WINDOW OF SOLAR
VIDEO UPDATE — This video references the July 4th Safe Harbor deadline, which has now passed. The good news: the 40% Tax Credit is still available if you start by October 2026 and activate by the end of 2027. See the updated timeline below.
Good news: Battery tax credits aren't going anywhere. Since these incentives are locked in until 2033, you can focus on your solar installation now and easily add storage later without missing out on the savings.
Don’t Build by October 31st —Just Start The Process.
HOW TO LOCK IN YOUR 40% CREDIT BEFORE IT'S GONE
Projects that start now can be activated any time through December 31, 2027 and still capture the full credit.
Based on IRS guidance for projects beginning construction after July 4, 2026. Consult Sunistics Group for project-specific guidance.
The October 31st Rule: Start by October 31st, 2026 to leave runway for design, permitting, and utility interconnection before the 2027 deadline.
The Benefit: Your 40% credit and Year-1 depreciation are secured the moment your system is activated. No rushed construction.
Projects that start in 2026 also qualify under lower domestic-content requirements than 2027 starts — one more reason to move this year.
Why Waiting Until 2027 Is Too Risky
With the industry rushing to lock in incentives,
utility and permitting bottlenecks are inevitable.
Start the process no later than October 31, 2026
This leaves enough runway for interconnection and activation before the December 31, 2027 deadline.
Faith-Based Orgs & Non-Profits
You are eligible for the 40% via 'Elective Pay' (Direct Pay), receiving the credit as a cash refund.
You must meet the same 2027 activation deadline.
