Solar battery guide

By Carly Nichols

What is a solar battery? 

A solar battery stores excess energy generated from solar panels, this excess energy can be used at night to power appliances.  

Kevin, a Brighte customer installed batteries with his solar system, "being able to store energy during the day, and use it at night means you are not at the mercy of your electricity provider"

What are the benefits of having a solar battery? 

By having a solar battery, you are less reliant on the grid network, creating smaller energy bills as you utilise energy generated from your solar system first.

What is the difference between a hybrid system vs off-grid? 

A hybrid system remains connected to the main electricity grid. A Hybrid system is able to utilise energy from the main electricity grid once the power generated from the solar system has been depleted. 

Off-grid system or a stand alone system, has no connection to the main electricity grid. All of the homes power comes from their solar system and battery, off-grid systems are larger than hybrid systems as the requirements are greater. 

As a backup, some off-grid systems have a generator that can be utilised if there is a greater demand for power.

Battery information: 

Talk to your solar installer about the below factors, to help decide which battery would best suit your household needs.

  • Rated Apparent AC Power (kVA)
  • Nominal Battery Capacity (kWh)
  • Depth of discharge
  • Usable Capacity (kWh)
  • Min Operating temp
  • Max operating temp
  • Outdoor usage

The three most common battery types are; Lithium-ion, lead-acid, and flow battery.

How long does a solar battery last?

The length of time your solar batteries last, depends on a myriad of factors, speak to your installer about your home. Brighte Tip: Check your warranty.
