A battery storage system, also known as an energy storage system or home battery, is a device that allows you to store the electricity generated by your solar panels or from the grid at low tariff times, for use when you need it.
Using home batteries to store the electricity generated by your solar panels can help you maximize the use of renewable energy in your home. This can also reduce your reliance on electricity from the grid, which can lower your energy bills.
Even if you don’t have solar panels, you can still use home batteries to take advantage of time-of-use tariffs by storing cheap electricity overnight and using it during peak times. Some energy companies offer these tariffs, and it is expected that more will become available as they can help balance energy supply and demand and reduce the need for fossil fuel generation during peak times. Home battery storage can also reduce the use of fossil fuel backup generators for off-grid homes.
When choosing a home battery for solar panel storage, it’s important to consider the amount of electricity your home uses on a daily basis. The average home uses about 8 kWh per day, so you’ll want to select a battery with a capacity that can cover your evening and nighttime electricity usage. The capacity of lithium-ion batteries ranges from about 1 kWh to 15 kWh.
It’s also important to consider the output of your solar panels, as you don’t want to choose a battery that is larger than your panels can charge. We can help you determine the right size battery for your home’s energy needs and your solar panels’ output. While a well-chosen battery can provide enough electricity to meet your evening needs for most of the year, you may still need to use grid electricity during the longest winter nights.
