The setup
Kwame and Abena Mensah have no roof for solar, so they added a compact battery in a hallway cupboard.
Kova fills it on the cheapest half-hours, runs the flat from it at peak and enrols it in grid flexibility events.
“No solar, no garden - and the flat still pays us back every winter.” - Abena Mensah
What made the difference
Flexibility payouts of £212 a year turned a battery in a cupboard into a small power station.
