Missouri solar power overview

With many of the major state utility rebates set to expire in 2023 and the federal tax credit coming to an end in 2021, the best time to go solar in Missouri is now! 

The state’s renewable portfolio standard is also coming to a close in 2021, meaning that the value of renewable energy credits will also start to decrease. The longer you wait to go solar in Missouri, the fewer savings you will receive in order to make solar a worthwhile investment.

Are solar panels worth it in Missouri

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.

Missouri solar incentives & tax credits

Federal solar tax credit

The most significant incentive to install solar panels for homes and businesses 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 Missouri is now.

 

Net metering

Missouri utilities are required to offer net metering to their customers. When your home solar system produces more electricity than you use in a given billing period, you will receive a credit for each excess kilowatt-hour (kWh) of energy you send to the grid - these credits will be applied to your next bill. 

However, Missouri only requires excess generation to be credited at the utility’s avoided cost rate, which is less than the retail rate. 

While receiving credits equal to the retail rate would offer greater savings on your electric bill, getting credited at the avoided cost rate still provides some savings, which is better than none.

Is it better to lease or buy solar panels in Missouri

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 Missouri 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 Missouri will fall during 2020.

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

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 Missouri, licensure is regulated at the municipal level.

 

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 Missouri?

What are the pros and cons of installing solar panels in Missouri?

The advantage of installing solar panels on your home in Missouri is that many utilities offer rebates for installing solar systems. Also, state policy mandates that utility companies must offer net metering to their customers.

The disadvantage of installing solar panels in Missouri is that net metering only has to be offered to customers at the avoided cost of electricity. This means that your utility has the ability to reimburse you for less than the retail rate of electricity for each excess kilowatt hour (kWh) of energy you send to the grid. Also, if you want to take advantage of utility rebates, you often have to give your utility provider the rights to your renewable energy credits (RECs) for 10 years.
