Maine Solar Incentives — Complete Guide
Solar Property Tax Exemption
Maine exempts renewable energy equipment — including solar arrays, inverters, and paired battery storage — from property tax assessment.
Legal Basis
The exemption was established by LD 1711 (2019) and applies to all residential solar installations connected to the grid or used for on-site consumption.
Coverage
The exemption applies to the full value of the qualifying solar and storage equipment, and there is no time limit on how long it lasts.
No action required — the exemption is automatic.
Sales Tax Exemption
Maine does not charge sales tax on solar energy equipment purchases.
The 5.5% state sales tax is automatically waived for:
- Solar panel systems
- Inverters
- Racking
- Related components
No action is required — the exemption is automatic.
Class 1 NEPOOL-GIS Renewable Energy Credits (RECs)

How It Works
