Solar panels help generate renewable energy for your home during the day and the battery supports your power needs after the sun goes down. It’s the best way to secure affordable energy costs for the long term, allows you to have power to certain circuits during a blackout, and be part of the local Virtual Power Plant.
When solar panels make electricity during the day, you need to use the power straight away in the house to get the full savings. If you don’t, your solar power goes back to the grid and you only get a small credit in return as part of your electricity retailer’s solar feed-in-tariff, which varies from retailer to retailer.
By adding a battery, you can store your extra daytime solar power so that you can use it at night. That way, you rarely need to use expensive grid power, and you aren’t leaving your electricity bill exposed to prices that seems to be flying up every year.
