The Southwestern Ontario farm solar market

Southwestern Ontario (Chatham-Kent, Essex, Lambton, Middlesex, Elgin) is Canada's largest row-crop agriculture region — corn, soy, winter wheat dominate. Farm solar fit is driven by livestock-operation + greenhouse electrical loads rather than crop-side power. Chatham-Kent in particular hosts a growing greenhouse cluster that pencils for larger (200-500 kW) commercial-scale solar.

Three local considerations for Southwestern Ontario farms

check_circleHydro One rural service distribution is the default for most Southwestern Ontario farms — rural interconnection timelines run 4-8 weeks typical, longer than urban LDC territory.
check_circleHog + poultry barns need IEC 62716 ammonia-rated solar modules to survive the ammonia-rich air environment — $0.05-0.08/W adder over standard modules.
check_circleChatham-Kent + Leamington greenhouse zone concentrates significant commercial solar demand on packing-shed rooftops adjacent to greenhouses.
