Whether you have a solar panel system at your home or not a home battery can be used to store electricity and deliver it to your home appliances and devices.

A solar panel system will last you 30 to 35 years. Sunlight that reaches the solar panels generates electricity that is stored into the solar light batteries and is used once it is dark outside. After 25 years your solar panels won t necessarily need to be replaced. The benefits of a home battery are clear especially during short or long term outages.

However it is essential to remember that their performance levels will have deteriorated slightly over that time period. However their ability to absorb sunlight will be reduced.
