5kW System Installed by Absolute Energy Solutions

“The service Cameron gave us was great, he took the time to get to know what we were after and asked us questions to make sure we were going to get a system that would give us the most out of installing solar.”

Cameron from Absolute Energy Solutions provided Damon and his family an excellent service after being connected through the Solar Market obligation free, solar quote form.

Damon’s priority was to ensure he chose a solar installation company who could provide the best quality system that his family could afford and would be suitable for their needs.

“The service Cameron gave us was great, he took the time to get to know what we were after and asked us questions to make sure we were going to get a system that would give us the most out of installing solar.”

Since installing the 5kW solar PV system back in 2017 Damon has seen his electricity bills drop from $750 per quarter to $200.

“We’ve had no issues with the system in the 2 years of having it. During the day we set timers on some of our large appliances but we (Damon, wife and two children) still use quite a bit of energy at night. We get a bit back from the 17c FIT for our excess energy that goes to the grid.”

Damon was very impressed with the service provided by Absolute Energy Solutions throughout the installation process and has continued to have contact with them regarding the possibility of adding battery in the future.

“I was very pleased with the cleanliness of the work. All the wiring was neatly blended and hidden.”

Absolute Energy Solutions also assisted Damon with installing an app so he could track what the system was generating and followed up after the installation with a phone call to check it was all running smoothly.

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.
