What are the pros and cons of installing solar panels in Montana?
The advantage of installing solar panels in Montana is the state-mandated net metering requirement. Privately-owned utilities must offer kilowatt hour (kWh) credits for excess energy generated by solar systems. The state also offers a tax credit to homeowners who install renewable energy systems. This tax credit is capped at $500. Montana law also offers property tax exemptions for solar energy systems.
The disadvantage of installing solar panels in Montana is that there is very little in the way of utility-based rebates. Also, Montana does not receive as much sunshine as other states so a solar system here will produce less than a system in a sunnier state, like Arizona.
However, the available state-based incentives combined with the federal tax credit more than make up for what the state lacks in sunshine. With the incentives that are currently available, now is the best time to go solar in Montana!

What rebates, solar tax credits, and other solar incentives are available in Montana?
Net metering in Montana
Solar, by its nature, generates the most power during the middle of the day when most people are at work or school and little power is being used in the home. The net metering policy in Montana mandates that for every surplus kWh generated by solar (like the excess energy your system creates during the day) utilities must provide a credit that is equal to the full retail rate of electricity that will be applied to future bills to offset costs. However, at the end of the annual billing cycle, any excess credits on your bill will expire without compensation.
Residential Alternative Energy System tax credit
Montana offers residents a tax credit when they install a renewable energy system on their property. The tax credit is equal to 100% of the costs, up to $500. If there are two taxpayers living in a household, the two can file jointly for a $1,000 tax credit. The credit is then applied to the homeowner’s income taxes.
This is a great opportunity to save on the installation of a solar system.
Property tax exemption
Montana homeowners save big on their property taxes when they install residential solar panels. Installing a solar system on one’s property would usually cause an increase in property taxes, however, the property tax exemption excludes 100% of the assessed costs associated with the solar system from the homeowner’s property taxes. The exemption lasts for 10 years.
