Solar Battery Installation in Chesterfield, MO

Duracell, Enphase, SolarEdge, and Tesla home batteries, installed with new solar or added on their own to the solar system you already have. We serve Chesterfield and surrounding St. Louis County communities with design, permitting, utility paperwork, and installation handled by one team.

We install four home battery brands. We recommend one based on the inverter you have or plan to use, what you want backed up, and where the battery will go.

Already have solar? We add batteries to existing systems, including systems installed by another company. We look at your inverter, electrical panel, and utility agreement, then recommend the battery that pairs cleanly with what is already on your roof.

A standalone battery install doesn't require new panels. We handle the design, permit, utility paperwork, installation, and app setup.

Ameren Missouri nets your solar production against your usage each billing period under Missouri's Net Metering and Easy Connection Act. Excess production is credited at Ameren's avoided-fuel-cost rate (currently 3.84¢/kWh in summer and 3.39¢/kWh in winter), well below the retail rate, so we size systems to offset your own usage rather than to export power.

Missouri doesn't offer a state solar rebate, and Ameren Missouri's solar rebate program closed at the end of 2023. The federal residential solar tax credit also ended for systems installed after 2025. What still makes solar pay off in Chesterfield is offsetting the power you would otherwise buy from Ameren Missouri at retail rates.

Because excess production is credited at a low avoided-cost rate, the right system for a Chesterfield home is sized to your 12-month usage, often paired with a battery so more of your solar is used in the evening. You can pay cash or finance the system with a solar loan.
