Solar + battery installation in Prince Edward Island

Prince Edward Island runs genuine 1:1 net metering, set by section 13 of the Renewable Energy Act: the kilowatt-hours you supply are subtracted from the kilowatt-hours delivered, and a monthly surplus is credited to your account in kilowatt-hours. The constraint is the calendar. Those credits hold no cash value, and on 31 October each year any credits outstanding from the preceding calendar year expire unless your net metering agreement sets another compliant date, so a system sized well beyond your own consumption banks value that is written off once a year. Generators are capped at 100 kW and installations of 30 kW and larger may need three-phase service, so neither limit binds a normal house. Two utilities apply the same rule separately: Maritime Electric across the Island, and the City of Summerside's own electric utility within Summerside. Both charge 17.84 cents per kWh on the first 2,000 kWh of a billing period and 14.23 cents above that, effective 1 August 2026, and a net metering customer pays one service charge even though two meters are installed.
