Off-Grid Solar in Vancouver Island
Rural year-round homes; off-grid cabins on west coast / north island; boat-access islands; island retirement properties
Vancouver Island off-grid market
Vancouver Island hosts BC's largest residential off-grid market by install count. North Island (Port Hardy, Port McNeill area), Sooke / Jordan River west coast, and the Gulf Islands-adjacent mainland corridor all have strong off-grid demand. Four-season rural homes dominate; cabins + glamping on the west coast add growth.
Typical system sizing
Year-round rural home: 10-16 kW solar + 25-40 kWh battery + 12-16 kW backup generator. West coast cabin: 4-8 kW solar + 15-25 kWh battery + 10 kW backup generator.
Winter design considerations
December production 0.7-0.9 kWh/kW/day — among Canada's lowest due to coastal rainforest cloud cover. Oversize solar array 30-40% vs Prairie design, or plan for 50+ generator hours per winter.
Grid-extension reality
BC Hydro extensions $25/metre past standard allowance. West coast and north island backlots commonly $20k-$80k extension cost.
Local gotchas to know before you quote
Islands Trust jurisdiction on some southern island areas restricts panel placement. PST exemption applies to all solar equipment.
