What solar panel installation costs in Honolulu
Construction pricing in Hawaii runs 35% above the national average, so solar panel installation here typically lands between $22,604 and $27,518 for a typical 7 kW system. At Hawaii's 42.3¢/kWh electricity rate, a system that size offsets a meaningful share of a typical bill. Note: the 30% federal solar tax credit expired December 31, 2025, so these are gross prices — any quote still showing a federal credit is out of date.
Figures are modeled from 2026 national baselines adjusted by a Hawaii cost factor of 1.35. They are estimates for comparison, not quotes — your property, access and material choices move the real number.
