Boise Solar Overview
Boise and the Treasure Valley enjoy excellent sunshine—over 200 sunny days per year. Idaho Power serves most of the area, and while Idaho's solar policies have been evolving, the region's good production potential and moderate growth make it an emerging solar market.

The Bottom Line
Boise solar faces the challenge of excellent sunshine but low electricity rates.Idaho Power's rates are among the lowest in the country, extending payback periods to 15-20 years. Solar can still make sense for those who value energy independence or expect rate increases.
Best candidates: High-usage homes (especially with AC or EV charging), those who value environmental benefits, or homeowners planning 15+ year ownership. Rising Idaho rates may improve economics over time.
Considerations: With weak economics, carefully evaluate whether solar provides enough value for your situation. Energy efficiency investments may offer faster payback in Idaho's low-rate environment.
