That's $3500 US at 65c exchange and you will need 2 they are only 10kWh. You will need 14 panels to charge the batteries and a backup generator when the sun don't shine. You have nearly $18k before you before you have screwed a panel to the roof. I imagine the system will be completely stuffed in 10 years. Say it costs you $25k. That's $2500 a year.
