Solar Rebate Frequently Asked Questions solar rebate

Rebates can be a tricky topic of conversation. Here are a few frequently asked questions about solar rebates.

1. By How Much Will The Solar Rebate Reduce By?

As previously explained in our blogs, every year on January 1st solar rebates are reduced. To calculate a solar rebate use the following formula: kW solar system size X deeming period in years x zone rating= the number of STC’s you’re eligible for.

Once you know how many STC’s you are eligible for, times the number of STC’s by $37 as this is the average rate of an STC (STC’s can range from $34 -$40).

Let’s say you are looking at installing a 6.6kw system in zone 1. In 2020 you would have received a rebate of roughly $4357. In 2021 you will receive a rebate of roughly $3960. This is a rebate reduction of $397.

2. Is Solar Worth It Anymore?

Yes, because regardless of rebates or feed-in tariffs, solar panel systems allow you to self-generate electricity- meaning you do not have to buy energy from the grid during the day. Solar panel systems are an asset that has a short return on investment and keeps you saving for up to 25 years!

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.
