Not only is the City installing solar panels in public places, but many energy conscious residents are installing panels like these at their homes. These panels are installed in the backyard of a friend's house.
A set of panels like these generate about 2500 kWh of electricity in a year. Surplus power is fed into the electricity grid and generous rebates are paid; currently 44 cents per kilowatt hour.
The Federal Government is currently encouraging people to install systems like this by offering a rebate of up to $8,000. A six panel, one kWh system can be installed for about $4,000 (after the rebate).
