From Andrew Till / Mr. EV
.

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.

The system was installed by Heatable. Use these links to get a quote and get some money off if you go ahead:
