Adelaide 1 is a 10-megawatt (MW) solar photovoltaic (solar PV) facility located on approximately 49 hectares of land in the township of Adelaide/Metcalfe, west of Strathroy, Ontario. Completed in eight months, construction highlights included excavation of substation area for footings and foundations; construction of the substation and control house; installation of culverts across ditches to the public roadways; installation of panels, transformers, inverters, and cabling; and testing and commissioning.
The project consists of more than 49,000 solar PV modules that generate direct current (DC) electricity when exposed to sunlight. The solar panel arrays are mounted off the ground in rows with a fixed tilt angle to the south to catch the sun’s rays. Energy collected by the panels is collected through underground cabling by inverter/transformer pairs, which convert DC electricity to alternating current (AC) at a specific voltage. The AC current then continues from the inverters to a single main facility substation, where the main power transformer increases the voltages to suit the electricity distribution grid.
Delivered under Ontario’s Feed-in Tariff program, this project is expected to produce approximately 13.6 million kWh of electricity per year, enough to power approximately 1,300 average homes. More than 60 percent of the materials for this project were made or sourced from Ontario.
