Yes, very much so. Only recently has the Canadian owned utility company
monopoly even allowed homeowners to use solar to reduce demand on their
inefficient diesel powered generating system and previously had no cogeneration
buy-back program.
I’m looking into solar as our next project down there but I’m even more
concerned about the RFI potential than the pool pump. “Properly designed
(RFI-wise)” is the key.
Stay tuned!!
