Electricity Rates by State

Your local electricity rate is one of the biggest factors in determining your solar savings and payback period. States with higher utility costs — like Hawaii at $0.39/kWh and California at $0.28/kWh — see the fastest solar ROI, while states like Idaho ($0.10/kWh) still benefit thanks to state incentives and rising utility prices. Explore the rates and solar potential for each of our focus states below.

Why Electricity Rates Matter for Solar

Higher Rates = Faster Payback

Every kilowatt-hour your solar panels generate offsets electricity you would have purchased from the utility. The higher your rate, the more each kWh of solar production is worth and the faster your system pays for itself.

Rising Utility Costs

Electricity rates have historically risen 2-3% per year. Going solar locks in your energy cost for 25+ years, protecting you from future rate hikes and increasing your total lifetime savings.
