STC's are Small-scale Technology Certificates.
REC's are Renewable Energy Credits.
1 STC = 1 REC, they are the same power value, the difference between them is how much they are traded or sold for!
Where LGC's are Large-scale Generation Certificates for solar farms over 100kW.
As a guide, one LGC is equal to one megawatt hour of eligible renewable electricity. Once created and validated, these certificates act as a form of currency and can be sold and transferred to other individuals and businesses at a negotiated price.
Remember, REC's is a measurement of renewable energy that are traded or sold.
All On-Grid systems intending to claim either STC's & LGC's must be installed according to the requirements of the Renewable Energy (REC) Scheme, in order for them to be eligible for Small-scale Technology Certificates (STC’s). These certificates can be assigned to a registered Agent such as a retailer or installer in exchange for a financial benefit, such as a discount off the invoice.
As STC’s are created based on the expected output of the system, they can be created as soon as the system is installed & approved by the Clean Energy Council (CEC). The system does not need to produce any power before its STC’s are created.
In effect, this provides an up-front discount for those who purchase solar systems from Retailers, BUT, the not so well known fact is, the two page REC's Claim Form allows the Retailer to Grab the Customers STC Credits of the next 11 years.
Customers can negotiate to Pay the installers directly & fill in a simple two page Form, to creating the STC Credits, there is no risks associated with holding onto or selling them, this is something that many Retailers/Installers don't tell the Customer!
For Example: In 2019 the STC's for a 6~6.5kW system, equates to approx. $3'000~$4'000.00 in Government Credits that the Customer can get deposited directly into there own bank account, all done by the Installer simply signing off on the Installation. |
