Solar Incentives for Wyoming

Every dollar you can save on your solar installation — updated for 2026.

Last updated: March 2026

⚠

Federal ITC: Expired for Homeowners

The 30% residential ITC (Section 25D) expired December 31, 2025 via the One Big Beautiful Bill. Systems installed in 2026+ receive zero federal tax credit if homeowner-owned.

However, if you lease your system, the installer can still claim the business ITC through 2027 — and pass savings to you through lower lease payments. Contact us to see how much you can save with a lease.

Available Incentives

Even without the federal credit, Illinois has some of the best solar incentives in the country.

Best IncentiveUpdated Apr 2026

Illinois Shines RECs (ComEd)

~$7,453*

Avg. est. (50% yr 1 + quarterly over 6 yrs)

The Illinois Shines program pays you for the Renewable Energy Credits (RECs) your solar panels generate. You sign a 15-year production contract, and the estimated REC value of approximately $7,453 (based on average system size in Wyoming) is paid as follows: 50% in the first year after installation, with the remaining 50% in quarterly payments over the next 6 years. REC values went up for the new program year. Actual value varies based on your system size and production. The customer receives approximately 85% of the gross value — the remainder covers the approved vendor's fee and a 5% collateral held against underproduction. Cash/finance buyers receive this payment directly. Lease customers benefit through lower payments — the installer carries the 15-year contract liability.

REC Price: ~$80.77/REC

Contract: 15 years

Eligibility: Small DG ≤25 kW residential

Net Metering

~6-8¢/kWh

Post-January 2025 installations receive credits at the supply rate only (~6-8¢/kWh), not full retail. Credits never expire and roll forward month to month. Pre-2025 systems are grandfathered at full retail for 30 years.

Battery Storage Rebate

$300/kWh

Add battery storage and receive $300 per kWh rebate. A 10 kWh battery gets $3,000. Stackable with solar DG rebate. The upcoming Virtual Power Plant program (launching mid-2026) will let you earn additional revenue from your stored energy.

How this is calculated

Illinois Shines measures value in RECs (Renewable Energy Credits). 1 REC = 1,000 kWh of solar production. More sunlight and more panels means more production — and a higher REC value.

Annual Production7.5 kW × 3.8 sun hrs × 365 days

10,403 kWh/year

Annual RECs10,403 kWh ÷ 1,000

10.4 RECs/year

Total 15-Year RECs10.4 × 14.2 (contract multiplier)

147.7 RECs

Gross REC Value147.7 RECs × $90.37/REC

$13,350

Tier: 0–10 kW • Ameren IL territory • 2026-2027 program year

+$20/REC Customer-Owned Adder applied ($70.37 base + $20.00 adder)

Estimated Customer REC Value$13,350 × 85%

$11,347

~15% goes to approved vendor admin fee + 5% collateral for underproduction

Tier note: Your 7.5 kW system falls in the 0–10 kW tier at $70.37/REC base. Systems over 10 kW drop to the 10–25 kW tier at $60.92/REC — a lower per-REC rate, though more total production may offset this.

Estimates based on 2026-2027 IL Shines Distributed Generation REC prices published by the Illinois Power Agency. Actual REC value depends on your system's measured production, which varies by roof orientation, shading, and panel efficiency. Lease customers benefit from RECs through lower payments — the installer claims the RECs and carries the 15-year production contract.
