Myth #2: The bigger the battery, the bigger the savings
Fact: Most households just can’t fill a big battery year round
Our solar experts analysed the energy use of around 1500 of our electricity customers. They found that most solar households aren’t generating enough solar to fill a big battery (like a Tesla Powerwall) all year round. Instead, we suggest you look at how much energy you’re exporting in winter and use that information to help you determine what size battery is right for you. You can use our free battery sizing calculator to help.
