Factors Affecting Solar Panel Installation Costs in Missouri

Various factors affect the cost of solar panel installation in Missouri. They include:

Size of Your Solar Panel Installation

The size of your solar panel installation will dictate how much you pay. The average cost of installing solar panels in Missouri is $2.59 per watt. But this average cost decreases with increasing system size.

Like in other commodities, the laws of bulk buying apply to solar panels. Per watt, larger systems cost less to install.


Let’s consider installation costs by system size.

System Size in kW Average Cost Per Watt Average System Cost

(Before Tax Credits)

4 kW $2.83 $11,320
5 kW $2.71 $12,400
6 kW $2.59 $15,540
7 kW $2.56 $17,950
8 kW $2.59 $20,720
9 kW $2.50 $22,500
10 kW $2.48 $24,800

Note: The costs above reflect installation prices before tax credits. Plus, the numbers above are only averages. They may vary from vendor to vendor.

Your Energy Needs

When it comes to solar installation, you buy the system that fits your needs. Energy requirements dictate the size of your solar system. Your energy needs depend on the power consumption of all your electronics and how long you use them in a day.

To learn how to calculate your energy needs, check out our article on building an off-grid solar system.

Your Solar Equipment Preferences

Your choice of solar panels has a direct impact on installation costs. There are two classes of solar panels, monocrystalline and polycrystalline PV panels. Monocrystalline panels tend to be more expensive due to their high efficiency. Check out this article to learn how the two options compare.

Inverters costs also vary widely. Expensive options will increase installation costs.

Solar Incentives in Missouri


In addition to the factors above, solar incentives can influence solar panel installation costs. Governments of different levels use tax credits to make solar energy affordable. Incentives are also tools to encourage people to embrace solar power.

As a Missouri resident, what solar incentives apply to you?

The Federal Investment Tax Credit (ITC)

The federal ITC incentive that applies to homes is known as the Residential Clean Energy Credit. Offered by the federal government, the Residential Clean Energy Credit is available to all Americans. It reduces your solar installation costs by 30%.

Let’s see how the Residential Clean Energy Credit affects the costs of different system sizes.

System Size in kW Average System Cost

(Before Tax Credits)

Average System Cost

(After Federal Tax Credit)

4 kW $11,320 $7,924
5 kW $12,400 $8,680
6 kW $15,540 $10,878
7 kW $17,950 $12,565
8 kW $20,720 $14,504
9 kW $22,500 $15,750
10 kW $24,800 $17,360

The 30% tax credit is available until the end of 2035, after which it will be reduced to 26%. In 2034, the federal ITC drops further to 22%. By 2035, the federal Investment Tax Credit won’t be available for residential solar installations.

Until then, use this federal tax credit to your advantage.
