- How much battery storage do I need?
- We suggest 1 or 2 days storage – check your bill to see what you use per day, eg. the average house uses around 8 Kwh, so 8-16 KWh is sensible for average consumption homes.
- During the day, when solar panels are generating more power than your home is using, excess power is diverted to the battery for use later. When the sun goes down, or if you’re using more energy than your panels are providing, the battery will kick in to give you power and prevent drawing from the grid – this will help save on bills.
- Average daily energy consumption depends on household size, appliances, and weather, among other things, which is why energy bills are usually higher during the darker, colder winter months – look at your bill to find out more.
- To maximise your solar PV installation and use as much of your own solar electricity as possible,ai
- for enough battery storage to be self-sufficient during non-generatinghours (usually the evening or gloomy day). Less than optimal battery storage is still worthwhile as it will help to reduce your bills.
