Solar incentives in MO

Columbia Water & Light - Solar Rebates

Value:Up to $800

Home and business customers of Columbia Water and Light may be entitled to rebates if they install a new solar PV system or water heater. The rebate amount is a fixed $400 for new water heaters, a fixed $800 for a solar water heater replacing a natural gas system, and a variable amount per kilowatt for photovoltaic systems. To qualify, customers must keep the system in operation for at least five years and participate in net metering and interconnection arrangements. Applications must be submitted before the system is installed. Additional information is available from the CWL website.

Energy Standards for Public Buildings

Value:Varies

Missouri most recently updated its statewide green building law in 2015. Any new state facility must meet standards set by the latest copy of the International Energy Conservation Code (currently 2015). Existing buildings must reduce energy consumption by 2% per year for a total 20% reduction in 2025. New remodeling projects affecting at least half of the building's area or costing half of its assessed value should be subject to pre-planning impact studies. Designers should consider on-site renewable energy and water reclamation to provide a 25-year cost/benefit analysis. Additional information is available from the Missouri DNR website.

City of Columbia - Renewable Portfolio Standard

Value:Varies

The city of Columbia, Missouri has a local renewable portfolio standard (RPS) program supplementing the mandatory state standard. Columbia Water and Light, as the city's public utility, is currently bound by ordinance to source at least 25% of its retail energy from renewable sources by 2022. Compliance is measured through regular proposals and reports addressed to the City Council. When possible, CWL must not increase the price of consumer energy by over 3% to fund new renewable energy investments. Additional information is available from the Columbia municipal website.

Empire District Electric - Solar PV Rebates

Value:Varies

Show Me PACE is a multi-jurisdiction property-assessed clean energy financing program in Missouri. Any county or city government may become a program signatory. The program serves business and multi-family residential property, farms, nonprofits, and public-sector facilities making energy or water efficiency improvements. A minimum principal of $50,000 is available at low market-rate interest. Repayment periods may vary, but cannot be longer than the useful life of the equipment that the loan funds. The Missouri Energy Initiative oversees the Show Me PACE lending market. Additional information is available from the program website.

Energy Loan Program

Value:Varies

Public/private school districts, local governments, and hospitals may be eligible for special financing on energy efficiency improvements through the Missouri Energy Loan Program (MELP). The revolving loan fund is managed by the state's Department of Economic Development. Available principal ranges from $10,000 to $1 million. Funding can be repaid over 10 years at 2.75% APR and with a 1% administrative fee. Monthly payments are typically based on estimated cost savings. Additional information is available from the DED Energy Division website.

Renewable Energy Standard

Value:Varies

Missouri's mandatory renewable portfolio standard was created in 2008 by the Proposition C ballot referendum. The standard sets minimum quotas for renewable energy investment. Current objectives (as of 2021) require the state's power industry to source 15% of retail energy from renewable sources by the end of the year. Any solar, wind, biomass, hydrogen fuel cell, or select solid waste reclamation system may qualify. However, "carve-out" measures require a specific portion of the annual quota be fulfilled using solar energy. Compliance is measured through both renewable energy credit (REC) and solar carve-out credit (SREC) systems. Each credit pegs a fixed amount of electricity to a variable dollar value. Credits are subject to market forces as utilities buy them through net metering and retire them after three years. Annual reports on standard objectives and progress are available through the Missouri Public Service Commission website.

Columbia Water & Light - Home Performance with ENERGY STAR Loan

Value:Varies

Home customers of Columbia Water and Light may be eligible for special financing on ENERGY STAR certified building materials and equipment. Available offers will vary from time to time. Currently, loans are available for central and room HVAC, insulation/weatherization, solar water heaters/thermal systems, and some appliances. CWL works with loan partners to provide financing. Current repayment options can last up to ten years at variable interest rates. Applicants will be subject to standard credit checks, pre-installation audits, and final system inspections by CWL representatives. Additional information is available from the CWL website.

Net Metering

Value:Varies

Missouri requires any private/municipal utility, electric retailer, or utility cooperative to offer net metering contracts to renewable energy customers. Any solar PV/heating, wind, hydroelectric, or hydrogen fuel cell system qualifies to receive tariff compensation. Once a customer and their utility agree to a contract, the utility will install a bidirectional meter on the customer's system at no cost. This meter measures net excess generation (NEG) sent back to the grid. The customer's electric bill will be credited at a fixed avoided-cost rate for NEG generated during each billing cycle. Should generation exceed consumption for any given month, credits may carry forward to subsequent cycles. Additional information is available from the Missouri Department of Economic Development website.

Missouri Clean Energy District

Value:Varies

The Missouri Clean Energy District is a statewide property-assessed clean energy (PACE) financing program. Counties and cities may join MCED at any time, allowing local businesses, farms, nonprofits, and public-sector building owners to receive specialized loans for energy efficiency improvements. (Due to regulatory concerns from the FHFA, residential buildings are ineligible for PACE loans at this time.) PACE funding effectively comes from the government, but it is administered by the MCED and a number of banking partners. Loans are at low interest and can be repaid over up to 20 years. Repayments take the form of a tax lien senior to the property's mortgage; should the owner sell or transfer their property, the new owner will be responsible for continuing repayments. Additional information is available from the MCED website and member localities.

Interconnection Guidelines

Value:Varies

Any private/public electrical utility or cooperative in Missouri must offer their renewable energy customers interconnection and net metering contract options. Unlike other states, renewable energy systems are not divided into regulatory tiers based on size and capability; however, systems over 100 kW in capacity are ineligible for net metering. All systems must meet standards set by IEEE/UL and have manual disconnect switches/other safety features installed. Additional information is available from individual utilities.

Frequently Asked Questions

  • As a general rule, unless there are local limitations, the main limitations to the amount of solar panels you can put on your roof are the available space on your roof, your electricity usage, your providers net metering rules, and the limitations of your house hold electrical system.
  • Based on our research the average price per installed watt is $3.87 in Missouri. This means for a 10kW system you can expect to pay $38,700 though pricing can vary significantly between installers based on the projects requirements.
  • Based on a Zillow research study from 2019, home with solar panels sell for roughly 4.1% more.
  • To generate the most power, solar panels in the United States should face true south as this generally results in the solar panels receiving the most light each day throughout the course of the year. That said, given that energy prices are often variable throughout the day, your installer may recommend you rotate your panels slightly so that the panels will receive more light at the end of the day when energy prices can be more expensive. That said, for most consumers the positioning of solar panels is highly dependent on your home's roof.
