Solar for Small Business in Texas 2026:
Lowest Costs in the Country

Yes. Unlike the residential ITC (Section 25D, which expired December 31, 2025), the commercial ITC under Sections 48 and 48E remains available: projects that began construction on or before July 4, 2026 locked in the full timing pathway, and later starts still qualify if placed in service by December 31, 2027. The base rate is 30%. With domestic content (FEOC) compliance, add 10%. In an energy community, add another 10%. Low-income adders can bring the total to 50-70%. Small businesses under 1 MW automatically qualify for the 30% base rate without prevailing wage requirements.

MACRS (Modified Accelerated Cost Recovery System) lets businesses depreciate their solar asset on an accelerated schedule. Under OBBBA, 100% first-year bonus depreciation is permanent, so the entire depreciable basis is expensed in Year 1. The depreciable basis is the system cost minus 50% of the ITC. For a $100,000 system with 30% ITC, the depreciable basis is $85,000 ($100K - $15K), all deducted in Year 1. At a 25% tax rate, MACRS saves approximately $21,250 in taxes. (Businesses may elect out to the standard 5-year MACRS schedule if they prefer to spread the deduction.)

Texas has the lowest commercial solar installation costs in the United States. Small business systems (25-100 kW): $1.90-$2.20/W. Mid-size (100-500 kW): $1.60-$1.90/W. Large (500 kW-2 MW): $1.40-$1.60/W. A 50 kW system for a retail store costs approximately $95,000-$110,000 before incentives. After 30% ITC and MACRS, net cost drops to $44,000-$55,000.

C-PACE (Commercial Property Assessed Clean Energy) is financing attached to the property, not the business owner. In Texas, it is administered by the TX-PACE Authority. Benefits: 100% financing, 25-year terms, fixed rate, transfers with property sale, no personal guarantee. It covers solar, battery, HVAC, and building envelope improvements. Available to commercial property owners in participating Texas municipalities.

ERCOT commercial electric rates include demand charges based on your highest 15-minute peak usage each month. Rates range from $8-$15/kW depending on utility territory. Solar reduces peak demand by offsetting daytime usage when most businesses peak. A 50 kW solar system can reduce demand charges by $300-$600/month, adding $3,600-$7,200/year in savings beyond the kWh energy savings.

The §48E begin-construction window closed July 4, 2026: projects that began construction on or before that date locked in the full timing pathway, while new starts still qualify but generally must be placed in service by December 31, 2027. For small businesses, "beginning construction" means either (1) incurring 5%+ of total project cost, or (2) starting physical work of a significant nature at the site. FEOC-compliant panels include Silfab, First Solar, and Qcells (Dalton, GA plant), and keeping equipment FEOC-compliant protects the 10% domestic-content bonus.

Absolutely. Restaurants and retail stores have peak electricity demand during business hours (10 AM - 8 PM), which aligns perfectly with solar production. A 25 kW system for a restaurant costs $55,000 installed, netting $25,000-$30,000 after ITC + MACRS. Annual savings of $7,000-$10,000 deliver a 3-4 year payback. The demand charge reduction alone can save $2,000-$4,000/year.
