Welcome to the Ultimate Guide to Solar Panels in Missouri
This page is a complete guide to the complicated and sometimes confusing process of installing solar panels on your Missouri home. Since there's a lot to consider, we've separated the page into sections to help you find what you are looking for. If you find this page useful, please share it with someone who might also find it interesting!
** What's new for 2020 **
Some good news for homeowners in the state: The cost to install solar is lower than ever, and there are great solar rebates for 2020 to further bring down costs, for folks served by KCP&L, Columbia Water & Light, or Empire District. While some of the rebate tiers have gotten a little less juicy since 2018, there are very lucrative solar investment opportunities here, with some farm installations coupled with USDA grants creating immediate payback scenarios.
You can save thousands of dollars off the up-front cost of solar, combine that with another big cash windfall in the federal solar tax credit, and use electricity bill savings to quickly pay back your net costs. The average homeowner will save thousands over the 25-year operating life of their solar panels, and benefit from increased home value and environmental benefits, to boot!

Your Solar Strategy in Missouri
Figuring out the best way to go solar in Missouri can be a little daunting. From loans and leases to power-purchase agreements, there are a lot of options out there. To help you pick the one that might be best, we've created the handy decision tool below.
We'll ask you a few simple questions about you and your home. Once you're done, we'll recommend a good option. Further down this page, we provide cost estimates and example return-on-investment calculations for all the various options:
How to pay for solar panels in Missouri
The chart above shows the 25-year returns for an investment in solar whether you choose to purchase a system with cash or pay over time with a loan or Power-Purchase Agreement (PPA). As you can see, the purchase option leads to the highest dollar-amount returns over time, but look a little closer. Taking a solar loan or Home Equity Line of Credit (HELOC—the orange bars) and paying for the system over time means you'll actually spend less of your own money over time, while reaping a big financial benefit in year 1.
That's because you take a loan for the system, but you still get a 26% federal tax credit based on the entire cost. You'll start out ahead, so your payments over 15 years will have less impact on you than plunking down a big pile of money up front. All you need is equity or great credit.
Lastly, take a look at the blue bars. They represent a solar Power-Purchase Agreement (PPA), which is also called third-party ownership. With a PPA, you put $0 down on a rooftop solar system and make monthly payments that are little bit less than what you had been paying the utility company or their dirty energy. You still accumulate savings, because the PPA cost will rise by less than the electric company's annual rate hikes. Third-party ownership is an excellent option if you don't have any equity or cash to put down, and it still saves you money!
Where we get our numbers
All these estimates are based on the average home in Missouri, which according to the U.S. Energy Information Administration (EIA) needs just about 12,500 kilowatt-hours (kWh), and the homeowner (that's you!) has to pay approximately $1,417 for the pleasure of receiving that dirty energy from the utility company. To make enough electricity to offset that bill, the home would need a 10-kW solar system made up of thirty-one 325-watt panels, with an up-front cost of $27,000 after the state's rebates. Don't worry about that price, though—the rest of the available incentives and energy bill savings will take care of a big chunk of it after just 1 year!

How much can solar panels on roof save you?
Option 1: Paying cash for solar
An outright purchase used to be the only way to get solar, and it's still the option that provides the "biggest" financial returns. The reason we put "biggest" in quotes here is because it's technically true, but based on percent return for the money, a loan is a better option.
If you've got cash and you prefer to pay up front, you'll have to plunk down $27,000, but tax breaks and energy savings will erase a bunch of that after just 1 year. Over 25 years, your system will have produced more than $25,000 in income, after your system cost is paid back. The reason this works is that solar offsets your electricity costs—enough to save you about $1,500 in year 1, and it just goes up from there. As the electric company raises rates, you save more and more, and more...
Here’s how the numbers work for a 10-kW rooftop solar system in Missouri:
- Installing a typical 10-kW solar system should start at about $27,000 after the 2020 Missouri solar rebates. That's cheaper than solar has ever been, but it still might seem like a big investment. Don’t worry, because after tax breaks and energy savings, your first-year costs will be considerably less than that.
- The Federal government offers a great tax credit worth 26% of system costs after the rebate. So take 26% of $27,000, and you've got $7,020 you won't be paying to Uncle Sam next year. That brings your first-year investment down to $19,980.
- After the tax credit we subtract your first year’s energy savings, which we estimate to be $1,519. That reduces your cost after the first year to only $18,451.
- Those electricity savings will quickly make your money back, and your system will pay for itself in 12 years. That means free electricity until at least the end of your panels' 25-year warranty. We're talking $25,700 in savings over 25 years! The internal rate of return for this investment is not too shabby at 9%, but it likely isn't as good as if you just put the money into a mutual fund.
- And here's a nice bonus to consider: your home's value just increased by nearly $20,000, too (your expected cost after incentives).
- In addition to all that cash (and home value), you’ve created some green for the earth as well by not using electricity from fossil fuels. It's like planting 459 trees a year, every year your solar power system is humming.

Option 2: Using a loan to pay for solar
You don't need $27,000 sitting around to pay for solar. As long as you have equity in your home, you can still own solar panels and reap all the benefits. Heck, even if you do have the cash, getting a loan to pay for solar is by far the best option when it comes to percentage return on investment.
That’s because, in Missouri, using a loan to pay for solar is like investing in a business that's sure to succeed, and also earns you a tax break. That's right: a HUGE tax break!. You'll come out thousands ahead this year, and you'll still see a handsome profit over the 25-year life of your system.
A solar purchase like this will make sense for you if the following is true about you and your current situation:
- You can get a solar loan or home equity line of credit (HELOC) for $26,500, with a fixed rate of 4.5% or lower and a 15-year repayment period. Don't be put off if you're offered a higher rate. It just means a tiny bit less of the thousands of dollars you'll make with solar.
- You love making money without much risk.
Here’s how the numbers pencil out for an Missouri homeowner who makes a solar purchase with a loan:
- Installing a typical 10-kW solar system should start at about $27,000 after instant rebates. That's how big your loan will need to be to cover it.
- The electricity you'll save in the first year of operation would have cost $1,519, but your annual loan payments will be $2,479, meaning you would spend $960 on solar this year, but...
- You'll also see a huge tax break! The Feds give you 26% of the cost of your system back as an income tax credit, which in this case means $7,020. You'll be paying over time but getting the benefits up front!
- All those incentives mean you'll come out $6,061 ahead after year 1. Your loan payments will be about $80/month more than your energy bill savings, but that difference will get smaller as the utility company raises rates every year.
- By the time you've paid off your loan in 2034, you'll see yearly savings of over $2,000, and they'll keep getting larger as the utility raises rates. After 25 years, your total profit will be over $15,500!
- On top of the green that will stay in your pocket, your system will mean green for the environment, too—459 trees-worth, every year!

Option 3: Buying the electricity, not the panels with a Power Purchase Agreement (PPA)
A PPA is a great way to go solar if you haven't got stacks of cash or oodles of equity in your home. With thrid-party solar like this, it's possible to get solar panels for $0-down and see big savings over 20 or 25 years!
As for PPAs in Missouri: the electricity costs here a little below the national average. That means a PPA doesn't save you much right away, but it will bank you about $318 this year, so you're able to save the planet and make a little cash doing it!
Now that might not sound like a huge amount of money right now, but as the utility company raises rates, you will start to see greater annual savings. Over 25 years, our estimate shows a total savings of about $11,624. The panels will be installed and maintained by professionals, and all you have to do is brag to the Joneses down the street about your green habits!
How a PPA saves you money
Unlike a loan or cash purchase, a PPA means you don't own the panels on your roof. Instead, the solar company fronts the money for the installation, claiming all the available government incentives for themselves. Then over a term of 20 years (plus a 5-year renewal, in our estimate), they sell you the electricity produced by the panels, starting out a little cheaper than the fossil-fuel energy you had been buying from the utility company. Of course you'll still be hooked in to the grid to ensure you have power both when the sun is shining and when it's not, but the excess energy produced by the panels offsets your whole electicity bill just like it would if you own the system.
If you can get a good initial rate and a low escalator clause (the amount the PPA price increases per year), a PPA can truly be a win-win-win; for you, the solar company, and the environment. Of course, if you have the cash, equity, or credit, a solar loan is the best option. But for those without those things, a Missouri solar PPA can be a great option.

Missouri Solar Policy Information
Ever wonder why solar seems to be everywhere in some states, but not in others? We did too.
State legislatures and public utilities commissions can enact rules to make solar power accessible for everyone. Favorable rules explain why some of the cloudiest states—New York, New Jersey, and Connecticut, are doing so well with solar, and yet some of those with the most natural solar resources—like Alabama, Mississippi, and Georgia—are doing so poorly.
Below is important information about the public policy, rules, and economic reasons that affect your ability to go solar here in Missouri:
Missouri's Renewable Portfolio Standard
15% by 2021
A Renewables Portfolio Standard (“RPS”) is a law that basically says a certain percentage of a state’s energy production must come from renewable sources by a target date. Many states have passed such standards, with goals as high as 30%, even 40% renewable production in the not-so-distant future.
Missouri has an adequate but not spectacular RPS, mandating 15% renewable energy by 2021. The renewable energy target will be phased in via intermediate goals slowly over time, until arriving at the 15% total by the end of 2021.
Missouri’s RPS is critical to strong renewable energy policy. Utility companies aren't really all that gung-ho about you producing your own power. After all, it costs them money when you use less of their electricity. They also don’t naturally want to give you big payments for energy you're feeding back into the grid. The main reason the utilities are aiding your transition to lower electric bills and offering you incentives to put solar on your roof is because the state forces them to. If they don't hit their RPS numbers, they have to pay large fees back to the state.
Missouri's Solar carve-out and SRECs
.3% by 2021
A solar carve out means that, of the total amount of energy that must come from renewable power, a certain percentage must come from solar panels. Missouri has a solar carve out, albeit a tiny one, of 2% of the RPS (which means only 0.3% of all electricity generated in the state. That’s not very high, and it doesn’t set the bar very high for electric utilities, giving them little incentive to help homeowners install solar panels. Considering the original RPS in Missouri was brought into being by the voters in 2008 through Proposition C, it may be time to push for a new ballot initiative, something that didn’t happen back in 2012.
Missouri Electricity Prices
Missourians pay an average of 11 cents per kilowatt-hour (“kWh”) of electricity; just under 3 cents cheaper than the national average. Cheap, but not as cheap is it used to be. Higher electricity prices mean you’re probably already feeling a little strain in your pocketbook. Just don’t forget why electricity is so cheap.
That’s right, fossil fuels. Lots and lots of fossil fuels. Whatever your opinion of the environmental impacts of fossil fuels, one thing is certain: the financial cost of using them is only going up, up, up for the future. When that happens you’re going to be really happy you switched early to all that efficient, clean solar power that will be in high demand.
In the meantime, solar power will still save you a chunk of change here. We’ll go over just how much in a minute.
Missouri Net Metering
Net Metering requires your utility to monitor how much energy your solar power system produces and how much energy you actually consume, and make sure you get credit for the surplus.
Missouri requires all utilities to offer net metering to customers with solar power systems up to 100kW. Net excess generation is credited to your next bill at a minimum of the utility’s avoided cost rate.
Now, "avoided cost rate" is short for "how much it would have cost us to burn more coal and make electricity at one of our plants," and as you may guess, it's pretty cheap. Like, you pay $.12/kWh for electricity from them, but they'll only pay you $.03/kWh for excess that yo send back to the grid. That's why it's imperative that you size your system so you don't produce more electricity than you use. Talk to an installer near you to determine the best system size for your home.
We’d like to see the law amended to ensure that you get credit for your net excess generation, even if you run a surplus every month. And right now, all credit not used after 12 months reverts back to the utility without compensation. We think the utility should cut you a check for all that surplus instead.
Missouri Interconnection Rules
Interconnection in Missouri falls into the same solid but not spectacular range. You shouldn’t have any trouble getting on the grid due to circuit capacity limits – the most important first step. Also of note, all systems under 10kW (e.g., almost all residential systems) are exempt from any additional insurance requirements. Unfortunately you may still be required, at the utility’s discretion, to install a redundant external disconnect switch. We’d also like to see the 100kW system size limitation removed to allow commercial and industrial customers meet all on-site generation needs, but that doesn’t affect you and your residential system at all.
Missouri Solar Incentives
Next to high electricity prices and net metering, solar incentives have traditionally been the most important factor for whether home solar power makes financial sense in a state. In the past, some states with otherwise lousy policy had tremendous incentives that drove down the up-front cost of going solar so much that homeowners could save oodles of money even without net metering or a good RPS.
These days, the big incentive most people can get is the Federal Solar Tax Credit that earns you 26% of your total system costs back after just 1 year. State incentives play less of a role than in the past, but some really good ones are still out there, ready to help homeowners go solar and save money before you know it.
Let's see how Missouri measures up:
The availability of state solar incentives for residential solar systems was sourced from the Database of State Incentives for Renewables and Efficiency, utility company websites, and the state public utility commission.
Missouri Solar Power Rebates
Many utilities offer
Missouri has what basically amounts to a statewide rebate program for solar installations, because several of the state's largest electric utility companies offer rebates for their customers. Here's what's available for homeowners in Missouri:
|Ameren||$250/kW||Must be installed before 2023|
|Columbia Water & Light||$500/kW, up to $5,000||Must meet warranty and certification requirements.|
|Empire District Electric||$250/kW||Must meet warranty and siting requirements and be installed by 2023|
|Kansas City Power & Light||$500/kW||Must meet warranty and certification requirements; funds nearly exhausted|
Missouri Solar Tax Credits
Missouri does not offer any tax credits for solar power. Overall the statewide picture is pretty weak so far as solar incentives go. A tax credit would be an easy way to make solar cheaper for you without actually removing any money from the state’s coffers.
However, you can still take advantage of the federal solar tax credit.
Property Tax Exemption
A solar panel installation on your home adds value to it. We’re talking thousands of dollars of value, based on all that electricity you won’t be paying for in the next few decades. Luckily, Missouri realizes that a good way to encourage homeowners to go solar is to exempt all that additional value from property taxes. That’s right, you will not pay a dime in taxes on all that added value!
Sales Tax Exemption
Unfortunately, Missouri is not up to par on the other side of the tax-burden coin. One of the simplest ways for the Missouri state legislature to encourage small scale clean energy adoption is to declare solar panel equipment exempt from state sales taxes as many other progressive states have done. Sadly, there is no such declaration and will have to pay sales tax on the installation of solar panels for your home.
Low-income Solar Programs
Grade: FLearn more about low-income solar programs available in the U.S.
In 2019, Missourians can cash in on big utility-backed solar power rebates, saving thousands up-front and reducing payback time to just 11 years. The state still gets a “C” for policy, because we’d like to see a better RPS with solar carve-out, as well as a sales tax exemption.
Still, with solar prices lower than ever and the federal tax credit being reduced over the next few years, now is an excellent time for home solar in Missouri.
