Idaho Solar Panel Savings Calculator

Idaho Solar Panel Savings Overview

Idaho receives an average of 4.7 peak sun hours per day, providing a solid foundation for residential solar energy. With electricity rates averaging 10.9¢ per kWh — below the national average — longer payback periods are typical but savings still add up over time. The typical Idaho homeowner with a 6kW system can expect to save approximately $980 per year.

Solar Energy Production in Idaho

A standard 6kW residential solar panel system in Idaho produces approximately 8,234 kWh per year. This accounts for a system efficiency factor of 80%, which includes panel degradation, inverter losses, and temperature effects. At 4.7 peak sun hours per day, Idaho offers good solar production — enough to offset a significant portion of typical household electricity consumption.

Idaho Electricity Rates and Solar Context

The average residential electricity rate in Idaho is 10.9¢ per kWh according to EIA data. While this rate is below the national average, electricity costs are rising approximately 2-3% per year. Over a 25-year system lifetime, your cumulative savings will still be substantial. With utility rates increasing annually, your solar savings grow each year.

Idaho Solar Incentive Programs

Sales tax rebate for solar (partial). Federal 30% ITC. Some utility rebates. All Idaho residents are eligible for the federal 30% Investment Tax Credit (ITC), which reduces the cost of a solar system by 30% of the total installed price. Idaho also offers avoided cost net metering, allowing homeowners to earn credits for excess solar energy sent back to the grid.

Net Metering in Idaho

Idaho has avoided cost net metering, which is a significant financial benefit for solar homeowners. Under the avoided cost model, you receive credit at the utility's avoided cost rate for excess energy, which is typically lower than the retail rate but still provides meaningful savings.

Best Cities for Solar in Idaho

The best cities for solar panels in Idaho include Boise, Meridian, Nampa, Idaho Falls, Pocatello. Solar production can vary by location within the state due to differences in cloud cover, local shading, and microclimates. Southern-facing roofs with minimal shading produce the most energy. Homeowners in Boise and Meridian can typically expect production close to the state average of 4.7 peak sun hours per day.
