Best Solar Companies in Missouri

How Do We Rate Solar Companies?

TL;DR: We rate solar installers from 1 to 5 stars to help you pick the best one. High stars mean they’re really good at what they do and treat their customers right. Low stars? Not so much. We give credit to companies that have been around for a while, know what they are doing, have a high standard of workmanship and equipment, don’t hire subcontractors to keep the bar of solar installation quality high, and have good local reviews from real customers (yes, we check if the reviews are actually real or fake). Companies we choose as top-rated know and can help with federal and local solar incentives to help you save, have good financing plans, and guarantee their work. We’re here to point you to the solar companies that truly rock, making going solar easy and worthwhile for you.

Is It Worth Going Solar in Missouri?

Going solar in Missouri can be a worthwhile investment for many homeowners, but it depends on several factors including the cost of installation, available incentives, and individual energy consumption.

Cost of Solar Panels in Missouri

The cost of installing solar panels in Missouri varies, but the average price is around $2.59 per watt. For a typical 10.5 kW system, the cost before any incentives is approximately $27,195, which drops to $19,037 after applying the 30% federal solar investment tax credit (ITC). The cost can range from $17,472 to $30,576 depending on the size and efficiency of the system.

Incentives and Rebates

Missouri offers several incentives that can significantly reduce the cost of going solar:

• Federal Solar Investment Tax Credit (ITC): This credit allows homeowners to deduct 30% of the cost of installing a solar energy system from their federal taxes.
• Utility Rebates: Various utility companies in Missouri, such as Ameren Missouri, offer rebates. For example, Ameren provides a rebate of $0.25 per watt, which can amount to $2,525 for a 10.5 kW system.
• Net Metering: Missouri mandates net metering, allowing homeowners to earn credits for excess energy produced by their solar panels. These credits can offset future electricity bills.

Savings and Payback Period

The average payback period for a solar panel system in Missouri is around 10 years if paid upfront. Over 25 years, homeowners can save an estimated $18,292 on electricity bills. The savings can be even higher if electricity rates increase over time, as solar panels provide a hedge against rising energy costs.

Energy Consumption

Missouri residents typically consume more energy than the national average, with an average monthly usage of 1,028 kWh. This higher consumption makes solar panels more beneficial, as they can offset a larger portion of the electricity bill.

Environmental and Long-term Benefits

In addition to financial savings, solar panels offer environmental benefits by reducing carbon emissions and reliance on fossil fuels. Solar panels also increase property value and provide energy independence.

However, the decision should be based on individual circumstances such as energy consumption, available roof space, and financial situation. Homeowners are advised to get multiple quotes and consider all available incentives to maximize their investment.

How much does solar save homeowners in Missouri?

The average residential electricity rate in Missouri is approximately 13 cents per kilowatt-hour (kWh). On average, Missouri residents spend about $138 per month on electricity, which totals $1,656 annually. This rate is lower than the national average, which is around 15.45 cents per kWh.

Solar Panels and Cost Reduction

Installing solar panels can significantly reduce or even eliminate these electricity costs. The average cost of solar panels in Missouri is about $2.59 per watt, making a typical 6 kW system cost around $15,540 before any incentives. After applying the 30% federal solar investment tax credit (ITC), the cost drops to approximately $10,878.

Example of Savings

For a typical 10.5 kW system, the cost before incentives is around $27,195, which reduces to $19,037 after the ITC. Over 25 years, homeowners can save an estimated $18,292 on electricity bills. In Columbia, MO, for instance, an 11.2 kW system costing $32,000 before incentives can save homeowners $2,100 in the first year, $10,700 over five years, $22,500 over ten years, and $49,700 over twenty years.

Net Metering Policies in Missouri

Missouri mandates net metering for all electric utilities under the “Net Metering and Easy Connection Act“. Net metering allows homeowners to earn credits for the excess electricity their solar panels produce and send back to the grid. These credits can offset future electricity bills, enhancing the financial benefits of solar installations.

Details of Net Metering

• Credit Rates: The rate at which excess energy is credited varies by utility. For example, Evergy offers one-to-one net metering, while Ameren credits at 5.39 cents per kWh in the summer and 3.92 cents per kWh in the winter.
• Credit Expiry: Credits must be used within 12 months, or they expire without compensation.
• Avoided Cost Rate: Credits are often based on the avoided cost rate, which is the cost the utility avoids by not generating or purchasing additional power. This rate is typically lower than the retail rate.

Solar panels can substantially reduce or eliminate electricity costs for Missouri residents. With the combination of federal tax credits and net metering policies, the financial benefits of installing solar panels are significant. Homeowners can expect a relatively short payback period and long-term savings on their electricity bills.

Missouri Solar Incentives

Missouri offers a variety of incentives and rebate programs to encourage homeowners to install solar panels. These incentives come from federal, state, and local levels, making solar energy more affordable and accessible.

Federal Solar Incentives

Federal Solar Investment Tax Credit (ITC)

• The ITC allows homeowners to claim 30% of the cost of installing a solar photovoltaic (PV) system as a tax credit on their federal income taxes.
• Eligibility: The system must be installed between 2022 and 2032 to qualify for the 30% credit. The credit decreases to 26% for systems installed in 2033 and 22% for systems installed in 2034. There is no maximum amount that can be claimed.
• How to Claim: Homeowners must file IRS Form 5695 when submitting their federal tax return.

Statewide Solar Programs
