How much will a 1500W grid connected system save?
The average home uses about 20 kilowatt hours per day. The system will produce on average about 6 kilowatt hours per day. This will reduce your electricity bill by about $100 a quarter while reducing the amount of CO2 in the environment by about 2.4 tonnes each year. The solar system will also cushion the impact of future electricity price increases. If your state offers a feed-in tariff, your quarterly electricity bill could reduce by anything up to $1,450 a year in today’s dollars if you lived in NSW where the feed-in tariff is set at $0.60/kWh for every kWh your system produces.
