The average size for a solar energy system in Missouri is 10.5 kilowatts (kW), which puts the average solar system cost at roughly $27,195 before applying the federal solar tax credit, or about $20,124 after the credit is factored in. Keep in mind that there may be additional solar incentives and rebates available to you as a Missouri homeowner.

Missouri has some harsh winters, which may have some people wondering if it’s worth going solar in Missouri. Plenty of residents seem to agree that the energy cost savings of going solar are well worth it in the Show-Me state because residential solar installations have been on the rise.1 It’s also worth noting that the prices of home solar have fallen 11% in Missouri over the last five years, and with more solar companies working in the Midwest, installation costs are only expected to drop further.2

What Determines the Cost of Solar Panels in Missouri?

We’re not trying to sugarcoat it — the upfront costs of switching to renewable energy like solar panels can be costly. While the energy savings are great in the long run, you may be wondering why the cost of solar is so expensive in the first place. Let’s look at some of the factors that drive the cost of solar panels in Missouri:

Solar Equipment

The size and type of solar equipment you use will play the biggest role in how much your solar panel installation will cost in Missouri. For example, if you were to install a 5-kW system, you could expect to pay around $12,950, versus a 15-kW system at 38,850. 

In Missouri, you’d need roughly a 10.5-kW system to offset the average $115/month energy bill, but exact system size is determined on a house-by-house basis. You can get a rough idea of how many solar panels you’ll need based on your past electric bills, available roof space and the amount of sunlight your home gets. However, the only way to know exactly what solar energy system size you need is to get an assessment from a reputable solar company near you.

It’s not only the size, but the quality and name brand of the solar equipment you install that will change the price. There are three popular types of solar panels on the market — monocrystalline, polycrystalline and thin-film — and each comes with a different price tag.

Many of the major installers use monocrystalline solar panels because they are the most efficient. But even within that bracket, there will be some differentiation. For example, the solar installer SunPower carries the most efficient solar panels, so it tends to be a bit more expensive than other installers. Other solar companies may carry a wider range of solar brands and offer cheap solar panels or more affordable inverters that can reduce your overall solar installation cost in Missouri.

Solar Financing

Just like with most big purchases, the way you choose to finance your solar panels will affect the total cost of your solar project. Obviously, if you take on a solar loan with a high-interest rate, you’ll end up paying a lot more in the long run. Similarly, if you pay more, or all, of the cost of solar panel installation upfront, you’ll have less interest on the back end. 

We know it’s a big cost, but we recommend purchasing as much as you can up front to maximize your savings. We don’t suggest our readers enter into solar leases or power purchase agreements (PPAs) unless as a last resort, as you won’t be able to capitalize on all of the solar incentives available if you don’t own your panels.

Solar Installation Company

As mentioned earlier, different solar installation companies will offer different equipment brands that can alter the cost of your overall solar panel installation in Missouri. The good news is that there are over 121 solar companies in the state, with at least 43 providing residential solar installations, so you have plenty to choose from.3 We recommend shopping around and comparing different quotes from different companies before deciding on a solar installer.

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 federal solar investment tax credit, or ITC, allows homeowners to claim 26% of their system costs as a credit against the federal taxes they owe. The credit is set to reduce to 22% in 2023 and will be eliminated for residential systems in 2024 unless it is extended by Congress.
