Did you know? Non-compliant solar panels (non-AVL/DomCon) are available from $0.37/W, significantly cheaper than compliant panels ($0.60–$0.80/W). The 30% residential federal solar tax credit (Section 25D) expired December 31, 2025, so an owned residential system installed in 2026 receives $0 in federal credit regardless of panel choice; non-compliant panels also disqualify the Section 48E credit (lease/PPA/commercial) and IRA bonus credits (10% domestic content + 10% energy community). This calculator assumes compliant panels.See current ITC status →
