Frequently Asked Questions

  1. Sunlight - UV Rays activate the panels

  2. The solar panels turn UV light to direct current (DC) power

  3. DC power flows to the inverter, which converts the power to alternating current (AC) power for your home or to the Grid

  4. The Grid will pay you a feed in tariff (FIT) which will be a CREDIT on your power bill - you have this credit paid to your bank account.

Small-scale technology certificates or STC’s are tradable certificates which you can create and trade yourself or assign the right to create to a registered agent in exchange for an upfront discount off the cost of your system or a cash payment.

The majority of system owners choose to assign the right to STC certificates to a registered agent, as this is faster than creating and trading the certificates independently through the open market or STC clearing house.

All STC certificates must be created within 12 months in the Renewable Energy Certificate Registry (REC Registry) after your system is installed.

To create and trade the certificates yourself, this process involves 7 steps:

  1. Determining the eligibility of the small scale renewable energy system to be installed.

  2. Calculating the quantity of small-scale technology certificates to claim for your system.

  3. Obtaining and completing the appropriate compliance paperwork.

  4. Creating an account in the Renewable Energy Certificate Registry (REC Registry), which includes verifying your identity and an assessment as a fit and proper person.

  5. Creating STC certificates in the REC Registry within 12 months of the installation date.

  6. Waiting to have the STC certificates validated by the Clean Energy Regulator, and...

  7. Finding a buyer for the STC certificates or placing them in the STC clearing house queue for sale.

There are many systems with a huge variance in price, reliability, performance and warranties.

Typically, there are 3 types of Solar Panels:

1. Polycrystalline (Poly)
To make cells for ploycrystalline panels, fragments of silicon are melted together to form the wafers.

2. Monocrystalline (Mono)
To make cells for monocrystalline panels, silicon is formed into bars and cut into wafers.

3. Split Cell Technology (Split Cell/Half Cut)
Split cell Panels improve performance when partially shaded.

An Optimized Solar System greatly assists in shaded areas BUT it is much more expensive.

✓ All solar systems are installed in a string array, where the weakest panel reduces the overall performance.
