What Determines the Cost of Solar Panels in Missouri?

Solar panel systems in Missouri cost an average of $19,037 after the federal investment tax credit (ITC) is considered. However, you could be quoted anywhere from $14,500 to $25,500 the typical range of pricing in MO. 

The specific cost of your solar system will depend heavily on a few factors, which we’ll discuss below.

Solar Equipment

As you might have guessed, the type and brand of solar equipment you choose to go with will in large part determine your system price.

Luckily, Missouri homeowners experience ample sun an average of 206 sunny days per year, which is just above the national average. For states with less sunlight, system prices can be higher because high-efficiency panels are needed to make use of what little sunlight is available. 

This doesn’t apply in Missouri, which is partly why the average cost per watt for solar panels in the state ($2.59) is lower than in most others ($2.66).

Unfortunately, Missouri residents are no strangers to extreme weather. The state is located in Tornado Alley and gets hit with tornadoes and severe thunderstorms on a regular basis.

As a result, power outages are common, so many homeowners in the area add solar batteries to their setup. These can provide electricity during blackouts, but they do tend to drive up the cost of your solar energy system, sometimes by tens of thousands of dollars.

Solar Financing in Missouri

With solar panels in the Show-Me State costing over $20,000 on average, the financing method you’ll use is an important consideration. Many residents don’t realize that the method of financing can actually affect the system price.

For example, a cash purchase requires that all costs be paid up front, but you’ll only be paying for labor and equipment. A solar loan doesn’t require a large up-front layout, but you’ll end up paying more for your system overall because of finance charges and interest.

Missouri makes solar financing more affordable for homeowners by offering Property Assessed Clean Energy (PACE) loans through the Missouri Department of Natural Resources.3 This program limits interest rates to make solar financing more accessible. 

Unfortunately, there are no solar loan options for low-income households, but there are grants available for businesses and government buildings.

Missouri Solar Installation Company

Just as would be the case with a general contractor or other professional, the solar installer you choose can have a significant impact on the price you pay for your solar equipment. Even if you choose an identical system from two different vendors, your price could be hundreds or thousands of dollars apart because of differing equipment and labor charges.

A company’s average pricing can also vary based on the equipment brands it carries. Just taking a look at the top solar companies in Missouri — RisingSun Solar and SunPower — the price difference is likely to be in the thousands because of the brands each one carries. 

RisingSun installs panels from REC, Tesla, SolarEdge, Enphase and Silfab, and SunPower only offers Maxeon panels. These brands vary widely in cost as will the total system costs proposed by different companies.

It’s worth mentioning, however, that choosing a company based on more than just cost is important. SunPower might be more expensive, but its warranty is outstanding, as are its panels’ durability and efficiency ratings.

Additional Considerations and Costs in Missouri

Below are some additional considerations you should think about before going solar in Missouri.

  • Permits: All solar panel systems in the State of Missouri must have building permits prior to installation. These need to be pulled by an electrician in most cases, so double check with your installer that they will handle the permitting process.
  • Licenses: Missouri is one of the few states that doesn’t have general contractor licenses, and there are no specific licensing requirements for installing solar panels. However, you should make certain your company is registered with the MO Secretary of State, as is required by law.
  • Warranties: Solar warranties are crucial, not only because they protect your system from damage and improper installation, but also because they help guarantee a certain level of efficiency. You might want to prioritize warranty coverage when shopping around, as longer and more comprehensive warranties bring a ton of value to your system.
  • HOAs: Missouri is one of many states that has solar rights laws. These prohibit HOAs, specifically, from preventing homeowners from installing solar panels.
  • Environmental zoning: The zoning laws in Missouri don’t normally prevent you from installing solar panels, although you might run into issues with ground-mounted panels in some cases.

Missouri Solar Incentives

Missouri is not one of the top states for solar, but solar panels are becoming increasingly popular in the state. It could be because Missourians are seeking energy independence from utility companies, or perhaps they’re interested in lowering their electricity rates through net metering. Or maybe they just want to capitalize on the pros of going solar.

Whatever your reason for making the switch to clean energy alternatives, we want you to get the maximum reward. We’ve outlined some of the solar incentives available in Missouri below:

Missouri Solar Incentive How it Affects the Cost of Solar Panels in Missouri
Property Tax Exemption Even though installing solar panels boosts your home’s value, Missouri law ensures your property taxes won’t budge.
Net Metering Missouri lawmakers passed legislation in 2007 that requires all electric utilities to offer “true net metering” to customers with solar photovoltaic systems up to 100-kW.4 If you don’t know what net metering is, here’s our guide.
Local Solar Rebates & Incentives Be sure to check with your city government and utility provider for any additional incentives offered in your area. For example, Columbia Water & Light, Kansas City Power & Light and Liberty Utilities all offer rebates for installing PV systems.
Federal Solar Tax Credit The solar investment tax credit, or ITC, allows homeowners to claim 30% of their system costs as a credit against the federal taxes they owe. The credit is set to reduce starting in 2033 before being phased out completely for residential systems in in 2035, unless extended by Congress.
