Can businesses still get the 30% federal solar tax credit in 2026?

Yes! Unlike residential, commercial solar still qualifies for the 30% Section 48E ITC through December 2027. Businesses can also claim MACRS 5-year accelerated depreciation. Combined, these benefits can cover 45-50% of system cost in year one. This makes commercial solar economics better than residential.

What is MACRS depreciation for commercial solar?

MACRS (Modified Accelerated Cost Recovery System) lets businesses depreciate solar equipment over 5 years. With bonus depreciation, often 100% in year one. After claiming 30% ITC, you depreciate remaining 85% of basis. At 21% corporate rate, this adds ~$17,850 benefit per $100k system on top of the ITC.

How long is payback for commercial solar?

4-7 years typical for commercial solar, compared to 10-15+ years residential. Why faster? Commercial gets 30% ITC + MACRS (residential purchased systems get neither). Higher energy usage means more savings. Larger systems = lower cost per watt. After payback: 15-20+ years of near-free electricity.

What are commercial solar financing options?

Three main options: Cash purchase maximizes tax benefits (ITC + MACRS), best ROI. Commercial solar loan preserves capital while still claiming tax benefits, payments often less than energy savings. Commercial PPA has no upfront cost—developer claims benefits, passes savings as lower rate. PPAs work well for tax-exempt organizations.

Is solar worth it without the federal tax credit?

Yes, solar can still be worth it without the federal credit, especially in states with good net metering, high electricity rates, and strong state incentives. PPA and lease options still include the 30% commercial credit through 2027, passing savings to homeowners.

How much maintenance do solar panels require?

Very little. Solar panels have no moving parts and are designed to withstand weather. Occasional cleaning (1-2 times per year) can help if you are in a dusty area. Monitoring your system's production online helps catch any issues early.

Quick Answer

Commercial solar in 2026: businesses still get 30% federal ITC (Section 48E) plus 5-year MACRS depreciation—benefits homeowners can no longer access for purchased systems. Typical payback: 4-7 years. A $100k system yields ~$47,850 in first-year tax benefits (30% credit + ~$17,850 depreciation at 21% rate). Commercial solar has never had better economics relative to residential.

Commercial Solar Overview

Commercial solar is fundamentally different from residential solar - and in many ways, better. I spend a lot of time helping homeowners, but when a business owner reaches out, the conversation changes completely. Businesses can still access the federal Investment Tax Credit (ITC) plus accelerated depreciation (MACRS), creating significantly better economics than residential installations in 2026.

💡

From my experience:

Here is a reality check that surprises people: with the residential ITC gone for purchased systems, commercial solar now has a massive relative advantage. A business buying solar gets the 30% federal credit plus MACRS depreciation. A homeowner buying solar gets nothing federal. That gap is the widest it has ever been. If you own a business with suitable space, this is genuinely the best time to go solar.

Tax Benefits & MACRS

Investment Tax Credit (ITC)

The Section 48E ITC provides a 30% tax credit for commercial solar installations. Unlike the residential 25D credit that expired, businesses can still claim this for purchased systems through December 2027.

MACRS Depreciation

Solar is eligible for 5-year Modified Accelerated Cost Recovery System (MACRS) depreciation. Combined with bonus depreciation, businesses can often depreciate the full system value in year one.

Tax Benefit	Value	Example ($100k system)
30% ITC	30% of cost	$30,000 tax credit
MACRS (after ITC reduction)	~85% × tax rate	~$17,850 (at 21%)
Total First-Year Benefit	45-50%	~$47,850

Consult with a tax professional for your specific situation.

The Bottom Line

Commercial solar has the best economics it has ever had relative to residential.With the residential ITC expired but commercial benefits intact, businesses have a significant advantage. Payback of 4-7 years, combined with 25+ years of energy savings, makes commercial solar an excellent business investment. If you have suitable roof space, parking lots, or land, now is an excellent time to explore commercial solar.

[Editor's Note, Jan 2026]:Section 48E commercial ITC is scheduled through 2027 with potential phase-down after. If you are considering commercial solar, getting started sooner locks in the full 30% credit. The MACRS depreciation is not scheduled to change, but bonus depreciation rules have shifted before. Talk to your accountant about timing.
