Prices dropped 20%+ in the last 2 years. Combined with the rebate, payback periods are now 5-8 years — the best they've ever been.
Most homes with a 6.6kW solar system and average usage need a 10-13.5kWh battery. Smaller households (1-2 people) can get away with 5-7kWh. We calculate the right size based on your actual usage, not a guess.
The Cheaper Home Batteries Program provides rebates through STCs (Small-scale Technology Certificates). The value depends on your location, battery size, and the current STC price. For a typical 10kWh battery, the rebate is roughly $1,200-$2,400. Our calculator gives you a precise estimate.
