What does this estimate mean?
This is an illustrative program payment before charging costs, equipment costs, taxes and other fees. It is not net profit, a quote, an eligibility decision or a multi-year promise. Installation rebates, winter products and other programs are excluded.
Confirm the current utility territory, enrollment, performance baseline, payment caps and provider agreement before relying on a result. Program rules and rates can change.
