6.6kW system through SAE Group

“They weren’t the cheapest of the three, but they were very informative and had great customer service.”

Alan Neill From NSW

After being so pleased with the solar system at their previous property, Alan and his wife decided to invest in a solar system at their new residence in May 2018. By using the information on the Solar Market website Alan was able to stay informed on the current market and was connected with 3 different providers for obligation-free quotes.

“Solar Market were excellent and reliable, providing good updates when on the website”

After initial contact and a home visit Alan opted to install a 6.6kW system through SAE Group who he said was extremely informative and provided a great service.

“They weren’t the cheapest of the three, but they were very informative and had great customer service. They came out a few times to the house and were very helpful when called on the phone.

The chaps were marvelous I couldn’t fault them on anything, very efficient.”

Alan runs his hot water off the solar system and on average sees the solar system producing around 25kW per day. Monthly Alan now receives electricity bills ranging from $0-$28 since installing.

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.
