1. Reduction in purchase price

When you install a solar system, you generate Small Technology Certificates (STCs), which are sometimes referred to as a ‘Government Rebate’. You’ll receive 1 STC for every Megawatt of energy your system is expected to produce until 2031.

For example, a 5kW system (approx 20 panels) will produce around 96MWh worth of electricity over the 14-year period until 2031, meaning you are entitled to 96 STCs.

Once your system has been installed and the STCs have been registered, they can be sold to recover a portion of the cost of purchasing your solar PV system. Given the complexity surrounding creating and selling STCs, it’s common practice to assign the right to create the STCs to your solar provider, in exchange for an upfront discount off the full, or ‘true’, system price. 

STCs currently trade for around $38 each, which means you’d receive a $3,650 discount off the full, or ‘true’, cost of a 5kW system.

Infinite Energy will quote a price to you that is inclusive of the STC discount. This is the final price of your system.

2. Credits for excess power

The biggest benefit that your solar system will give you is offsetting your daytime electricity tariff. For every unit of electricity your solar power system produces and that you consume means that you do not have to purchase that unit from your electricity retailer.

Your electricity retailer will also purchase any electricity generated by your solar system that you don’t use yourself. This may include a contribution from the State Government.
