Montana solar power overview

Going solar in Montana is a great investment for your home. State law requires privately-owned utilities to offer full retail net metering to their customers. Montana also has a personal tax credit that residents can claim when they install a renewable energy system on their property. 

Full net metering, the state tax credit, and the 26% federal tax credit make going solar an excellent choice for Montana homeowners.

Are solar panels worth it in Montana

Solar panels have fallen in price by more than 80% in the last ten years. In 2020 they also remain subsidized by the 26% federal tax credit and the net metering law, making them an excellent investment. They offer a return well above the long term average return from both the share market and also property investment.

Another way to look at this question is the levelized amount you will pay for each kWh of power you will use over the next 25 years with and without solar panels. As you can see below the savings are significant.

Montana solar incentives & tax credits

Federal solar tax credit

The most significant incentive to install solar panels for homes and businesses in Montana is the federal solar tax credit. At the end of 2020, the amount of the credit will decrease from 26% to 22% of the cost of the solar installation. 

Because home and business owners want to get the largest incentive amount possible, solar panel installation companies will likely be flooded with new projects before year’s end. In order to maximize your savings potential, the best time to go solar in Montana is now.

Montana tax credit

When Montana homeowners install a renewable energy system on their property, such as a photovoltaic system, they are eligible for a state tax credit that is equal to 100% of the system costs, up to $500. In a home with two taxpayers, they can file jointly for a tax credit of $1,000.

The tax credit is applied to state income taxes.

 

Net metering

Montana law requires utilities to offer full retail net metering to their customers, meaning residents will receive the full retail value for each kilowatt-hour (kWh) of energy their solar electric systems produce.

Property tax exemption

Normally, installing a solar system would lead to an increase in property taxes. However, thanks to the property tax exemption for buildings using renewable energy, 100% of the assessed value of a solar system is exempt from property taxes for 10 years.

Is it better to lease or buy solar panels in Montana

You will save most money by buying your solar system rather than leasing it. Read more about the pros and cons of leasing vs buying solar.

How long do solar panels last?

Minimum of 25 years but generally 30 or more

How do solar panels work on a home?

Solar panels power your house when they can but your home uses the utility company for power at other times. In 2020 "solar systems with battery storage" are becoming more popular. These are known as hybrid systems.

How do solar panels work?

Grid-tied solar system

Solar panels are mounted on your roof and wired together in groups called solar arrays. The power they generate flows into a solar inverter where the direct current (DC) electricity is converted into alternating current (AC) electricity that can be used by your home or exported to the electric grid.

Off-grid solar system

Off-grid solar power involves meeting all your energy needs from the power of the sun. There’s no utility to fall back on. This means the solar installation needs to power the home not just during the day, when the sun is shining, but after dark as well.

Do solar panels require regular maintenance?

No, but cleaning them can improve power generation if they are dirty.

Will residential solar power system cost fall in Montana in 2020?

Given this environment, and the effect of import tariffs placed on solar panels by the Trump administration during 2018, it is hard to see that solar power system prices in Montana will fall during 2020.

Can you buy DIY Solar Panel Kits and install them yourself in Montana?

Yes you can! In some cases, you can save $3,000 or more when you install solar yourself, even after receiving the federal tax credit. Despite the potential for savings, data from Lawrence Berkeley Labs shows that only about 3% of homeowners choose DIY solar. 

Reasons for this include:

  • The permitting and inspection process for the utility, the state, and municipalities can be quite complex.
  • The installation work is both dangerous and difficult, with electrical work having to be performed at heights.
  • Often times, solar electricity customers will be charged a premium for DIY installations, which can limit savings.
  • In some states, a solar system needs to be installed by a qualified solar contractor in order to take advantage of incentives. In Montana, in order to be considered a qualified solar installer, contractors must hold a state electrical license. Utilities and incentive programs may have additional requirements.

 

SolarReviews does not recommend DIY solar installations unless you have suitable skills. However, for those who do, SolarReviews published a comparison table displaying solar panel kit prices from the top 10 leading solar kit websites in the US.

How much electricity do solar panel systems generate in Montana?

Depending on the location, solar panels will generate different amounts of electricity.

A solar system that is installed on a south-facing 24-degree pitch roof Montana will generate 1,550kWh of peak DC (direct current) capacity per year per 1kW in Montana.

Enter your details into the solar panel calculator to see how your location, roof tilt, and roof direction impacts solar panel production.

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. You also get to take advantage of that sweet $500 tax credit when you go solar. Don’t forget about your solar property tax exemption too!

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!
