How Electricity Rates Affect Solar Savings in Idaho
Your electricity rate directly determines how much you save with solar panels. Every kilowatt-hour your solar system produces offsets energy you would otherwise buy from the grid at 10.0 cents/kWh.
While Idaho enjoys below-average electricity rates today, rates have been trending upward. Solar panels lock in your energy costs for 25+ years, protecting you from future rate increases. With available state incentives and net metering programs, the economics still strongly favor going solar.
Idaho's net metering policy allows you to earn credits for excess solar energy sent to the grid, further enhancing your savings. This is especially valuable during summer months when your system produces more than you consume.
