What Solar Battery is Right for Me?

Here at Nepean Battery Solutions we are passionate about renewable energy. Adding Batteries to your new or existing solar system helps you maximise the most from your solar system.

Key Factors to consider when choosing a solar battery to add to your new or existing solar system:

  • Will your solar system generate sufficient excess energy from your solar panels each day to charge your battery?
  • Do you have sufficient space to install the battery?
  • What size battery will be needed to store and supply enough energy for your needs? This will depend on the nature of your household appliances, and your household energy usage patterns. Shift workers may have different needs from a family who all get home from work or school at the same time.
  • How do you expect to use your battery system? Is your aim to save money in the long term? To contribute to sustainability? Or have a backup plan for blackouts?

 There is no black and white answer to which Solar Battery is best, It entirely depends on your situation. At Nepean Solar we take the time to inspect your property in person and do an in-depth investigation to determine the best solar system and solar battery to suit your individual situation.

Benefits of Adding a Solar Battery Storage System.

Installing a Solar Battery Storage system can provide a number of benefits when installed in conjunction with an existing Solar System or as a new complete solar package.

A battery storage system can:

Store excess solar energy so it can be used at night.
Help further reduce your reliance on fossil fuel-based electricity from the grid.
Offset the increased cost of power used during peak times, such as during the evening.
Save money by storing energy from the grid overnight when prices are low to use during peak times when prices are high (depending on the agreement you have with your retailer).
Provide electricity to your home during power outages (depending on your system).

Can I Add a Battery to An Existing Solar System?

Wondering whether or not you can add solar batteries into your existing solar system, the simple answer in most cases is yes!

 There are several ways you can integrate a solar battery into your existing solar PV system.

First your existing invertor may already be battery ready, most inverters built in the last couple of years have this option.

Secondly if your invertor is not battery ready you can install a new invertor along side your current one to control the battery or replace the existing invertor.

Thirdly there are some batteries systems on the market that may fulfil your needs that don’t require a seperate inverter. 

Not sure if your invertor is battery ready? Speak to one of our solar experts at Nepean Solar today and we can help guide you through the solar battery process.
