The Hamilton commercial solar market
Hamilton's industrial heritage means more three-phase service availability than typical Ontario municipalities — relevant for larger commercial installs that would otherwise need a transformer upgrade. The steel and manufacturing legacy also means more installer experience with heavy structural engineering. Hamilton Mountain commercial market is particularly active for larger commercial rooftops.
