One year on from installing 30 solar panels and 20kWh of batteries, I’m finally crunching the real numbers.

We’ve saved nearly £3,000 in a single year — better than the installer predicted. I break down exactly how I calculated payback, what went wrong in April, how much our EV charging cost, and why electric radiators are killing our efficiency.
