Solar Panel and System Installations in West Boylston are subject to specific rules, guidelines, rates and regulations instituted by WBMLP and/or the Commonwealth of MA and the Federal Government. Please familiarize yourself with all rules before attempting an installation or hiring a contractor.

WBMLP SOLAR INSTALLATION RULES & TIPs
- • Residential solar system maximum size is 10kW (AC)
- • Commercial solar system size maximum is 90% of the average of the customers (12) monthly (calendar year) demand readings (kW), up to 60kW (AC) maximum
- • Minimize shading from foliage and structures to 20% or less
- • Solar panels should generally face between 90 degrees and 270 degrees (southerly)
- • WBMLP’s average residential electricity rate is approximately $0.145 per kWh and hasn’t increased since 2009
- • Customers derive the most value from offsetting monthly consumption and our $0.145 retail electricity rate, while minimizing the amount of extra solar generation we purchase
- • WBMLP will purchase hourly excess solar energy at the average monthly real-time price of energy in Central MA , which was on average $.035/kWh in 2024
- Consider a Battery Storage System to store excess energy generated during the day to use at night or during outages
- Consider using Electric Heat Pump HVAC equipment and Heat Pump Hot Water Heating to lower greenhouse gas emissions, reduce your operating costs, and match consumption with solar generation
WBMLP's SOLAR NET METERING POLICY
Please call WBMLP at 508-835-3681 or email us to receive an up-to-date copy of our “DG Metering Policy”. Residential customers can install distributed generation (DG) like solar systems up to maximum size of 10kW (AC). If you install a solar system, WBMLP will install a bidirectional meter which measures energy in two directions at the main meter socket. The DG net metering policy basically states;
- ☀ Any energy, measured monthly, delivered by WBMLP to the customer is billed at the full retail residential electric rate, and
- ☀ Any energy, measured monthly, received from customer to WBMLP is credited at the wholesale cost of energy (Based on monthly average real-time energy cost in ISO-NE WCMAS)
