How this calculator works
Savings assume the full retail rate offset at your province's average, with production from NREL PVWatts irradiance and an 86% system-efficiency factor. Costs use a fixed-plus-variable install model (permitting and interconnection do not scale with system size), so smaller systems pay back a little slower. Where your province pays less than retail for exports, the note above the results says so — that lowers real savings for export-heavy systems.
