The Small-Scale Renewable Energy Scheme (SRES) is the subsidy provided by the Federal Government. The solar power systems can create a Small-scale Technology Certificate (STC) that can be sold to offset the price of the system incurred by the user. These STCs have replaced the Renewable Energy Certificates (RECs). Feed in tariffs is another type of benefit that provides on-going financial incentives rather than an upfront price reduction. These tariffs may vary, so it is best to first check the rate per kilowatt of power.
