When my mother was setting up this house of hers, I found info on internet to give an aproximate cost for an complete installation (that gave 100% electricity to her house), and it wasn't that expensive... but she bought an electric generator (that she often doesn't switch on!
). I don't know how much sun you get in Canada, hehe, but sunny Mallorca can do very well on solar power (according to es.wikipedia: Hay 51 días de lluvia al año y 2.756 horas de sol. -> 51 rainy days per annum, 2.756 hours of sunlight).
