Adding a battery to your solar panel system is an easy way to expand its capabilities. The battery stores energy generated by the solar panels during the day, allowing you to use that energy at night or when your energy demands are greater than your solar panel output. You can specify a battery when you add a new solar panel system or add one later by retrofitting a battery to an existing system or expanding your current battery capacity.

Benefits of solar panel systems

Solar panel systems are extremely beneficial for reducing your carbon footprint and reducing your dependence on fossil fuel-generated electricity. By harnessing the power of the sun, you are decreasing your reliance on non-renewable resources, which means less pollution in the environment and cheaper electricity bills for you!

What are solar panel batteries?

Batteries are devices that store the electrical energy generated by solar panels. When the sun goes down or on cloudy days, batteries allow you to continue using electricity from your solar panel system. Batteries can also be used to store excess power from your panels and use it when needed, such as when your utility company charges more for electricity usage during peak hours or when there's a power outage in your area. A battery is a great way to maximise your solar panel system's capabilities.

Adding a battery to your solar panel system

A battery can be added to your existing solar panel system to increase its efficiency by storing unused energy for later use. This allows you to enjoy the benefits of solar power even during nighttime hours when there is no sun! 

Choosing the right battery capacity for your solar panel system is a key decision and one that should be made with care. A battery that is too small may not allow you to store enough energy during the day to meet your evening and nighttime needs. A battery that is too large, on the other hand, could cost more than necessary.

To guide you to the correct choice of battery capacity for your individual needs, it is important to know that batteries are rated in kilowatts-hours (kWh). The higher this number is, the longer it will take for a fully charged battery bank to discharge. So if you want more time between recharging cycles, look for a battery with a high kilowatt-hour rating.

Retrofitting a battery to your existing system doesn't have to be complicated

If you're considering adding a battery to an existing solar panel system, then it's important to understand the process of retrofitting the additional equipment into your home. The first step is to talk with a professional about the best way to do this. They'll be able to assess your current setup and determine whether or not retrofitting is possible. Installing a battery will typically take around 2-4 hours and will require some electrical work.
