Retail net metering
Exports are modeled at the same value as electricity bought from the grid.

Massachusetts Net Metering and Solar Export Value
Solar savings depend on two values: electricity you avoid buying from the grid and exported solar energy your utility credits back. This page explains how SolarCalcNow models export value as a planning assumption, not a final utility-specific tariff.
State planning note
Massachusetts savings are rate-sensitive; net metering, program rules, and utility territory can change the value of excess production.
The calculator uses 29.45 cents/kWh as the retail rate assumption for Massachusetts. Exported kWh may be credited differently from that retail value.
Partial export credit
Exports are modeled below the retail rate as a conservative planning default.
Modeled export value: 35% of retail
Low export credit
Exports are modeled at a low avoided-cost style value for stress testing payback.
Modeled export value: 10% of retail
What to verify before signing
- Your utility territory and rate plan.
- Whether exports are credited at retail, avoided cost, time-varying value, or another tariff.
- Whether unused credits roll over, expire, or settle at a different value.
- Whether batteries change savings or mostly add backup resilience.
What to do next
After checking export value, compare the same assumptions against installer proposals and incentive claims.
