As of the 1st January 2011, RECs have been replaced by Small Scale Technology Certificates, or STCs. Each solar hot water system or heat pump you purchase has been given a pre-determined STC value based on the model and the location it is installed in. Sydney and most of NSW is in Zone 3. The more energy efficient the system is, the higher the number of STCs that are assigned to the unit.
STCs are publicly traded like a share and their value fluctuates. Usually the STC value of your hot water system will be deducted from the cost to you, as a point of sale discount.
Some commonly used Solar Hot Water Systems and their STCs Value (Updated 31/5/12)
Apricus 315 ltr Mid Element Glass Lined tank with 30 tubes = 37 STC’s
Rinnai Prestige 330 ltr Closed Coupled with 2 x Excelsior FTC Panels = 39 STCs
Siddons Solar Stream 327 ltr Heat Pump = 26 STCs
Apricus 400 ltr Mid Element Glass Lined Tank with 40 Evacuated Tubes = 46 STCs
Rinnai Sunmaster 270 ltr Gas 26 with 2 x Excelsior FTC Panels = 43 STCs
Working out the reduction in price to you
You would take the system you have selected and multiply it’s STC value by the current trade price.
Eg: You select the Rinnai Sunmaster 270 Ltr with Gas Boost which has 43 STCs. Multiply 43 by the current trading value per STC, eg $33.
43 x $33 = $1419 Point of Sale Discount
This price would be deducted from your invoice by Hot H2o and clearly shown on your invoice so you know exactly how our pricing structure works.
