What is STC?

STCs are issued with qualifying solar systems and solar panel and can be redeemed for a dollar value that is deducted from the cost of the solar system. The value of an STC depends on market conditions at any given time. When you purchase your solar system from capital solar energy, we will provide you with the discounted value on your solar quote. Our main goal is to provide our customers with a hassle-free purchase. The discounted amount you get from STC is based on three factors:
  •  Zoning – where you live/reside
  • STC value – this amount fluctuates on the basis of market conditions
  • Deeming period – this differs every year and has a tendency to reduction every year.
  Zoning In Australia there is sum of 4 zones. These zones are distributed on the basis of how much renewable energy can be generated by a solar panel in a given area. Once you are aware about the zone you are residing. Following is the rating number of each zone: Zone 1 – 1.622 rating Zone 2 – 1.536 rating Zone 3 – 1.382 rating Zone 4 – 1.185 rating Solar system size (kW) x Postcode Zone Rating x Deeming Period (years) = Number of STCs (rounded down). Deeming period The deeming period is set by the scheme and it will decrease yearly until 2030. The shorter is the deeming period, the fewer STCs you get and the less discount you get. STC value The value of STC can be calculated by feeding the installation date, size of the system and your post code and the STC calculator it will provide you the number of STC s you are eligible for.
