2021 Solar Rebate Decreases | What You Need To Know

 

Every year on January 1st solar system rebates will decline until they will eventually come to a close in 2030.

At the moment, solar rebates are at the highest they will be ever over the coming decade.  So, if you’re thinking about installing solar? Now’s not the time to wait. Here’s how solar rebates are being phased out.

What Are Solar STC’s?

STC’s stands for Small-scale Technology Certificates.

Under the Small-scale Renewable Energy Scheme, small-scale solar systems are entitled to a number of these certificates.

These certificates are environmental credits that can be traded in exchange for an upfront discount on the cost of a solar system.

The more certificates you receive the more money the government will grant you. As a guide, usually one certificate is equal to one megawatt hour of energy your solar system will generate over its lifetime.

STC’s are calculated based on:solar rebate

  • Installation date
  • Deeming period
  • System location
  • Locations are divided into 4 zones with different ratings. The zones are as follows:

    Zone 1 = 1.622 rating

    Zone 2 = 1.536 rating

    Zone 3 = 1.382 rating

    Zone 4 = 1. 185 rating

How Solar Deeming Periods Work

As part of the Small-scale Renewable Energy Scheme, the amount of STC’s a solar system is granted is decreased annually meaning that the solar rebate also decreases. In 2020 those that install solar systems receive 11 years of STC’s in advance.

In comparison, in 2021 those that install a solar system will only receive only 10 years of STC’s in advance. See the table below for the declining deeming periods.

What STC’s Are You Eligible For?

Here is a simple formula to help you figure out the number of STC’s you’ll receive:

kW solar system size X deeming period in years x zone rating= the number of STC’s you’re eligible for.

How To Get Solar PanelsHow To Get A Higher Solar Rebate

The only way to ensure you are gaining the best solar rebate possible is by choosing to install your solar system sooner rather than later. At the moment the best rebate will be available until the 31st of December 2020.

Understanding Batteries

Off-Grid Systems

For some households a battery system can be of great benefit and minimise a home’s reliance on the grid. However, it’s important to understand for a battery to be useful your solar system needs to be generating excess energy for the battery to store, which you can then use at night or when the sun is not out.

When selecting a battery, you’ll want to invest in a system that is most suited to your home and can drive the best return on investment (ROI). Despite a larger upfront cost, a higher quality battery may significantly increase your ROI.

    Battery systems start from $6,000 and costs can vary greatly based on the following factors:

  1. Cycle Life-Time

    The number of times a battery can fully charge and discharge.

  2. Battery Power (kW)

    How fast it can be charged or discharged.

  3. Storage Capacity (kWh)

    The maximum amount of energy a battery system can store.

  4. Battery Management System (BMS)

    An electronic ‘smart’ system that gathers data and manages the battery ensuring it does not overload or operate outside of its safe functioning zone..

  5. Inverter

    Battery systems require their own inverter if your solar system does not have a hybrid inverter.

  6. 'All-In-One Unit’

    A system which includes the battery, BMS and an inverter all in one unit.

  7. Warranty

    Length of time or cycles the battery system is under guarantee.

  8. Blackout Protection/Backup

    It’s important to note this is not a common feature of a battery system and could cost thousands of dollars to include. Blackout protection not only requires additional components but also a specialised installation and rewiring. For grid-connected homes, the cost for blackout protection can outweigh the benefit.

Additionally, if your purpose for adding battery is to go Off-Grid and become completely independent from the grid you will need to ensure your solar system can generate enough energy to power your home and your battery system is large enough to store this energy. For homes in metro areas going Off-grid is not cost effective and is only recommended for those in remote areas with limited access to the grid. Off-grid solar systems with battery start at approximately $30,000.
