What Need To Be Considered While Buying Solar Battery

Energy conscious and environment-friendly consumers prefer using batteries for solar energy systems. It is definitely advantageous to use a solar battery for storage as Sydney gets maximum sunlight for more than 300 days. Storing solar energy will let you increase solar power usage, which further reduces electricity bills. To get the right batteries for solar energy systems, you need to check multiple parameters. We will cover the most essential parameters to be checked. This information will help you get the right batteries for your solar panels.

What to Consider When Buying a Solar Battery

1. Chemistry

In Australia, the selection of the best residential battery storage for solar systems needs to consider battery chemistry as explained hereunder:

  • Lithium-ion: Commonly, houses in Australia use this type of battery. It follows the same technology as smartphone batteries. Easily available and safe. Lighter than other available options.
  • Lead-acid: This battery for solar energy storage is perfect for houses using off-grid solar systems.

2. Efficiency

The efficiency of battery storage can be counted using two parameters:

  • Total energy battery can store, is known as nominal capacity.
  • Total usable energy is out of stored energy in solar battery storage, which is known as usable capacity.

3. Durability

The durability of the solar battery can be judged based on two factors. These two factors are often considered interchangeably:

zero dollar upfront cost
  • Warranty: The warranty of the solar batteries will be in years. For example, if a warranty is 12 years, then after that time, it will lose some storage capacity. 10 years warranty should be the minimum criteria for selection.
  • Cycles: Some batteries come with a warranty in cycles. One cycle indicates the complete charge and discharge of the battery. For example, 3650 cycles indicate 3650 times charge and discharge. Remember, residential batteries usually get charged and discharged daily.

4. Efficient Temperature Range

Usually, each battery for solar energy storage is sensitive to external temperature. If the temperature goes up or down than its predefined temperature range, then the battery might shut down or corrupt. Therefore, selecting the batteries, which can work efficiently in the temperature range of your location, is necessary for better results.

5. Power Generation

This is another essential parameter to be checked before buying a battery for solar energy storage. Power generation indicates the amount of power the battery can deliver. This information will be available in kilowatts. Examine the below-mentioned factors:

  • How much power battery can deliver when it is charged sufficiently?
  • What is the maximum deliverable power, also called peak power?

6. Depth of Discharge (DoD)

  • The value of DoD indicates the amount of safe energy usage. It means how much energy has to be left in the batteries to ensure batteries do not get damaged.
  • The value of the DoD will be shown in percentage.
  • Lithium batteries offer maximum DoD value. You can use up to 90% of your energy without hampering the batteries.
