Program summary
Maximize Savings with Tigo EI + Battery Storage in Maine
Homeowners and businesses in Maine can now reduce upfront battery costs and unlock long-term energy savings through the Efficiency Maine Small Battery Incentive Program.
Pair your solar system with Tigo EI Inverter + Battery, and take advantage of state-backed incentives designed to accelerate clean energy adoption—while improving resilience and energy independence.
Why This Program Matters
Energy costs are rising. Grid reliability is increasingly uncertain. And customers are demanding more control over their energy.
This program helps solve all three.
By installing a qualified battery system, customers can:
- Lower upfront installation costs with state incentives
- Store excess solar energy for use when it matters most
- Increase resilience during outages
- Reduce reliance on the grid
And for installers, it creates a powerful new reason to close battery-attached solar deals.
