Cost of Solar Panels in Idaho

The average cost of solar panels in Idaho is $2.60 per watt, which is slightly below the national average of $2.66 per watt. Idahoans enjoy lower electricity rates and have less demand for energy than much of the country, but most homeowners in the state still find that they need a 10-kilowatt system to offset their monthly electric bills of $95 per month.1 That comes out to an average of $26,000 to go solar before the 30% federal tax credit, or $18,200 after the credit.

What Determines the Cost of Solar Panels in Idaho?

Solar panel systems in Idaho can vary quite a lot in price, with most systems falling between $12,740 and $23,660 after the federal tax credit is accounted for. The range of pricing is so wide because there are a few major factors that can raise or lower your price by thousands. 

We’ll discuss the primary things that affect your system cost below.

Solar Equipment

If you’re trying to estimate your solar system cost, the first thing you’ll want to consider is the equipment you’re installing. 

It’s common for homeowners to pay above-average prices for solar panels where there is below-average sunlight availability. A lack of sunlight means high-efficiency panels, which are more expensive overall, are required.

Idaho doesn’t receive particularly intense sunlight given its location in the northern U.S., but it does experience about the average number of sunny days across the country (around 205). This being the case, high-efficiency panels usually aren’t required, so no special pricing considerations need to be added for higher efficiency.

Additionally, because Idaho isn’t particularly prone to extreme weather and the state uses many different power sources to generate electricity, the risk of outages is relatively low. This means very few homeowners feel the need to buy add-on products like solar batteries. 

These products increase overall costs, which means, once again, that prices can remain relatively low in Idaho.

Solar Financing in Idaho

When it comes to solar financing, you have four options: cash purchase, solar loan, solar lease and power purchase agreement. The one you choose will not only affect your long-term savings but also your overall system cost. 

Only a cash purchase and a solar loan will leave you with a system that you own, and a cash purchase gets you a system for less because there is no interest to be paid on top of the equipment and labor charges. Financing with a solar loan will cost you a few thousand dollars more overall than a cash purchase because of the interest.

Idaho works to promote renewable energy by providing some solar financing options to homeowners.

 First, the Office of Energy and Mineral Resources (OEMR) offers the State Energy Loan Program (SELP), which is available for up to $50,000 worth of financing for single-family residence solar systems. These loans have low APRs to reduce overall costs. SELP is in place of any official low-income solar loan. 

Idaho also offers Property Assessed Clean Energy (PACE) financing but only for commercial customers.

Idaho Solar Installation Company

The solar installer you choose in Idaho can affect your pricing as well. As is the case with companies in other industries, your solar installer will set its own prices for equipment and labor, so every installer will be different in terms of view of solar panels on a house

When you’re pricing out your system with different companies, it’s important to remember to consider the price as well as the quality of the equipment, as the equipment offered can have a significant impact on a vendor’s average cost. 

For example, Blue Raven Solar, one of the best solar options in Idaho, installs panels from Trina Solar, Canadian Solar and SunPower. The first two options are quite affordable, while the last is one of the most expensive on the market.

If you got a quote for solar from Blue Raven with SunPower panels and a quote from, say, Intermountain Wind and Solar with Enphase panels, the former will almost certainly be more expensive and might seem less appealing. 

However, SunPower panels are some of the best on the market and include an outstanding warranty and level of efficiency, so the value would be higher along with the price.

Additional Considerations and Costs in Idaho

Below are some additional considerations you should think about when deciding on a solar installer. These won’t have much of an effect on your pricing, but they are important.

  • Permits: Building permits are required by all municipalities in Idaho. Your solar installer should discuss with you who will be pulling the permits, but make sure to iron out those details before signing any agreements.
  • Licenses: The State of Idaho allows individuals with an electrical contractor license to install solar systems without any other special licenses. You should confirm that your installer has this license before committing to services.
  • Warranties: All major solar companies offer warranties that cover panel efficiency, installation, roof leaks and/or the equipment itself. The best warranties include coverage for all of the above.
  • HOAs: As of 2019, homeowners’ associations cannot prohibit solar panel installation in Idaho. The established solar laws mean that all homeowners have the right to go solar in ID.
  • Environmental zoning: Idaho’s zoning laws aren’t terribly restrictive when it comes to rooftop solar panel systems. You might run into issues with ground-mounted solar, though.

Idaho Solar Panel Incentives

With the average price of a solar energy system sitting at a costly $26,000 in Idaho, many homeowners are relieved to find that there are several solar incentives available from the state and federal governments. These incentives aim to make solar power more accessible. We’ll discuss the incentives available to Idaho residents below. 

Idaho Solar Incentive How it Affects the Cost of Solar Panels in Idaho
Residential Alternative Energy Tax Deduction This statute allows taxpayers an income tax deduction of 40% of the cost of a solar panel system. Taxpayers can apply this 40% deduction in the year in which the system is installed and can also deduct 20% of the cost each year for three years thereafter. The maximum deduction in any one year is $5,000. The total maximum deduction is $20,000.
Idaho Solar Easements & Access Laws In 2019, Idaho passed HB 158, which states that a homeowners association may not limit or prohibit the installation of solar panels or collectors on any property rooftop or structure within its jurisdiction.
Property Tax Exemption for Wind, Solar and Geothermal Energy Producers Installing solar will increase your home value, which typically triggers property taxes to increase as well. The property tax exemption states that your property taxes will not increase as a result of installing a solar panel system. This can save Idaho homeowners thousands or even tens of thousands of dollars over time.
Net Metering Through net metering programs, you can send any excess power your panels produce back to the local grid in exchange for billing credits from your utility company. Net metering is not required by law in Idaho, but the three largest utilities in the state – Rocky Mountain Power, Idaho Power and Avista Utilities – currently offer net metering incentives to their customers.
Local Solar Rebates & Incentives Utility companies and local governments may offer their own programs or rebates. For example, the Rocky Mountain Power Wattsmart residential efficiency program lets you save on products that increase your home’s energy efficiency, ultimately helping you eliminate electric bills and improving the value of your home and solar system.
Federal Solar Tax Credit The federal solar investment tax credit (ITC) is available to residents nationwide, including those in Idaho. This credit is applied to your federal income taxes owed, and it totals 30% of your entire solar system cost. In Idaho, where the typical system is $26,000, that’s an average credit of $7,800.

The Best Solar Panel Brands Available in Idaho
