Solar Panels on my roof were installed june2011. The cost then was $9990 for a 3.4kW system. On average the system makes 15 units per day which has a feed in tarrif of $0.52/kWh. Our household has received NO power bill since then and actually we have been sent quarterly $200 cheques from the energy company......
Now you can purchase a 5kW system for $5000 so..........
Solar, Hydro, Wind, Tidal and even Geo-thermal is the future.
