Can you save with a battery?
We want to find out how much our members with solar could save by installing a battery at home, so we’re setting up this trial. As part of the trial, you’ll get a battery at a discounted price, early access to our new app, and you’ll help us design the future of energy storage. If you’re a Bulb member, you can apply today.
