How current this is
Missouri program terms verified 2026-07. Programs change their terms, their budgets run out, and some close mid-year. Every amount here is an estimate until it is checked against your exact address and the equipment you actually install, which is what your quote does.
Rebate amounts are estimates and subject to change. Verify current program terms and eligibility before quoting a final net price.
Eligibility varies by income, equipment efficiency, utility territory, and program funding availability.
State and utility programs only. Federal 25C/25D tax credits expired 12/31/2025 and the DOE HEAR/HOMES rebate programs ended 5/29/2026; neither is included.
After-install rebates are claimed by the homeowner after installation and are not guaranteed at the point of sale.
