A Solar System on the roofs of homes and businesses uses energy from the sun to generate electricity cleanly and quietly to assist you in reducing your electricity costs and insulate you from rising electricity prices whilst at the same time making a big difference to the environment. When you’re producing your own power, you’re buying less from your retailer and selling your excess to them. You get a credit on your electricity bill for every kW you feed back to the grid (feed in tariff).
Consider the following examples. If you have 3kW of devices running and you’re producing 2kW, after one hour you would have consumed only 1kWh instead of 3kWh, saving between 45c to 60c in that hour. If you’re producing 3kW and only using 2kW, after one hour you would have sent 1 kWh back to the grid and not purchased 2kWh, saving even more. Remember that kWh is “units” on your power bill.
