The solar energy sector is experiencing a significant shift due to the “One Big Beautiful Bill” (OBBB). With critical deadlines approaching in just five months, failing to act promptly could result in thousands of dollars in lost tax credits and create obstacles for future solar projects. This comprehensive guide covers:

• Key deadlines for residential and commercial systems
• New restrictions taking effect in 2026
• Step-by-step actions to secure savings
• Expert answers to top FAQs

The recently passed bill extends some clean energy incentives but imposes strict new limitations starting in January 2026.

Industry Impact:

Solar analysts predict a 20-30% increase in system costs for projects delayed beyond 2025 due to compliance hurdles and inflationary pressures.

Case Study:

A Pennsylvania homeowner who started their project in August 2025 saved $9,300 by doing so, compared to waiting until 2026.

New Foreign Entity of Concern (FIOC) rules ban materials from:

• China
• Russia
• Iran
• North Korea

Problem:

Over 60% of global solar components currently originate from these regions.

Option A: Safe Harbor Before 2026

• Lock in current rules with 5% deposit
• Keep a 4-year installation window
• Avoid FIOC documentation headaches

Option B: Post-2025 Projects

The Treasury Department is expected to announce stricter safe harbor rules this summer, potentially:

Pro Tip:

Safe harbor your project before August to grandfather under the current terms.

Q: Can I claim the credit if installation starts in 2025 but finishes in 2026?

A: No—residential systems must be fully operational by 12/31/2025.

Q: Do ground-mounted systems have different rules?

A: Same deadlines, but may face higher lightning risks—read our protection guide.

Q: What if I miss the deadline?

A: Leases/PPAs remain available, but ownership savings disappear.

Q: How does FIOC affect battery storage?

A: Batteries face the same 2026 restrictions—safe harbor them now.

Q: Will extensions be granted?

A: Extremely unlikely—this bill intentionally sunsets credits.

Every day delayed risks:
* Missing 2025 installer slots
* Paying 20-30% more post-deadline
* Navigating FIOC compliance nightmares

Last Call:

Projects started after October 2025 may not be completed in time.
