My Shepparton home is about 70 years old, it's weatherboard and was built at a time when sustainability was barely in our vocabulary and while we have made many changes probably the most significant was the installation last year of a five kilowatt solar system, courtesy of Goulburn Valley Community Energy (GVCE).
Unfailing accurate advice came from GVCE Chief Executive Officer, Geoff Lodge (pictured), who gave what appears at this point appears to be a conservative estimate on the payback period.
The solar panels have delivered as promised cutting our power use from about 26 kilowatts a day to just a handful.
Geoff advised against a back-up battery arguing, again with figures, that batteries were not yet financially viable.He did say, however, that they were improving every year, becoming cheaper and would soon be a worthwhile proposition.
Our evaporative air-conditioner also draws on power provided by our solar panels and with the present heatwave (three successive days in excess of 35 degrees Celsius constitute a heatwave) will give us a clear indication what to expect as the temperature warms up.
