Solar Rebates and Net Metering

the sun in the sky

Columbia Water & Light provides rebates based on the overall capacity of a PV system (kW) as well as its energy production (kWh) during “peak” times. Peak times are periods of high system demand when electricity is most expensive for Water & Light to provide to its customers and normally occur on hot summer afternoons and evenings. The utility provides a premium rebate for PV systems designed to perform best during peak periods using azimuth, tilt and shading as determining factors. Net Metering Agreements and Rebate applications must be submitted by a Water & Light approved PV Installation Contractor.

Chart # 2- Unshaded production at Peak

For an estimate of unshaded production at Peak, choose the row/column corresponding to the tilt/azimuth of the array.

The color of the icon represents the Peak Factor found in Table #1. Orientations indicated with “X” receive no rebate.

This table is provided as a planning tool only. Site specific conditions such as shading of the PV array may greatly reduce its production. Final rebate amount will be determined using modeled output of the PV system using NREL’s SAM ( and/or SolarPathFinder.

The application includes a checklist of items you will need to receive a rebate.

Solar water heating is a simple, efficient, and affordable technology that can cut water heating costs by 50 – 80%.  A family of four generally needs two 4’ X 8’ collector panels connected to an 80 gallon storage tank.  The insulated tank holds the hot water until you need it.  It requires little maintenance and helps create a sustainable environment with less dependency on energy created from fossil fuels.

There is an $800 rebate for a natural gas water heating customer to convert to a solar electric water heating system. All electric customers can receive a $400 rebate for the installation of a solar water heating system and are eligible for a low-interest Solar Energy Loan.


Net Metering

The value of the excess electricity generated by the solar energy system and delivered to Columbia Water & Light, will be credited to the customer’s account at their current applicable electric rate. This arrangement offers the customer more than what the Missouri Statutes for net metering require. An Interconnection & Net Metering Agreement must be approved by the utility for the customer to receive a credit for the excess energy they generate. The utility retains the renewable energy credits (RECs) for the project. Customers choosing to retain the RECs for their solar energy system will receive credit for the excess energy based on the avoided average energy market price at the Columbia pricing node.

Columbia Water & Light reserves the right to reject interconnection of PV systems not meeting the net metering or rebate program parameters.
