Full methodology shown

Pricing methodology: System cost is auto-calculated from current market averages — $0.80/W for panels + $400 inverter (solar-only), or $0.75/Wh for battery systems with integrated inverter. No federal tax credit applied — the residential clean energy credit expired December 2025. Actual costs vary by installer, brand, and region. Utility rates sourced from EIA Form 861 (2024).
