14 years ago, the Labour government provided a generous rebate for residential solar systems installed called the Solar Homes and Communities Plan (SHCP).
When eko energy started the first community bulk buy program, our 1kW system cost $8,495, and with the government rebate, the householder was only out of pocket $495. The number of photovoltaic (PV) installers doubled to meet demand.
The rebate was scrapped in June 2009 and replaced with a smaller rebate through the Solar Credits Program, part of the Renewable Energy Target (RET) scheme.
Solar systems in those days were much more expensive than they are today, at around $3 per watt, but back then electricity rates were a lot less than they are now and the feed-in-tariff from electricity retailers was .60c (ex GST)! These days, it would be unlikely that a 1kW solar PV system could cover the energy required to run a home, even if there was only 1 person living there.
