Missouri Solar Panel Savings Calculator

Missouri Solar Panel Savings Overview

Missouri receives an average of 4.5 peak sun hours per day, providing a solid foundation for residential solar energy. With electricity rates averaging 13.1¢ per kWh — below the national average — longer payback periods are typical but savings still add up over time. The typical Missouri homeowner with a 6kW system can expect to save approximately $1,100 per year.

Solar Energy Production in Missouri

A standard 6kW residential solar panel system in Missouri produces approximately 7,884 kWh per year. This accounts for a system efficiency factor of 80%, which includes panel degradation, inverter losses, and temperature effects. At 4.5 peak sun hours per day, Missouri offers good solar production — enough to offset a significant portion of typical household electricity consumption.

Missouri Electricity Rates and Solar Context

The average residential electricity rate in Missouri is 13.1¢ per kWh according to EIA data. While this rate is below the national average, electricity costs are rising approximately 2-3% per year. Over a 25-year system lifetime, your cumulative savings will still be substantial. With utility rates increasing annually, your solar savings grow each year.

Missouri Solar Incentive Programs

Property tax exemption. Some utility rebates. Federal 30% ITC. All Missouri residents are eligible for the federal 30% Investment Tax Credit (ITC), which reduces the cost of a solar system by 30% of the total installed price. Missouri also offers full retail net metering, allowing homeowners to earn credits for excess solar energy sent back to the grid.

Net Metering in Missouri

Missouri has full retail net metering, which is a significant financial benefit for solar homeowners. Under full retail net metering, you receive credit at the full retail electricity rate for every kilowatt-hour of excess solar energy you export to the grid. This is the most favorable policy for solar homeowners.

Best Cities for Solar in Missouri

The best cities for solar panels in Missouri include Kansas City, St. Louis, Springfield, Columbia, Independence. Solar production can vary by location within the state due to differences in cloud cover, local shading, and microclimates. Southern-facing roofs with minimal shading produce the most energy. Homeowners in Kansas City and St. Louis can typically expect production close to the state average of 4.5 peak sun hours per day.
