December marked the end of a record solar year. Generation was lower than previous months, but battery management and the Cosy tariff kept costs down. Hopefully this overview is a useful guide to winter performance.

Solar panel performance declines over the years. I thought it might be interesting to see how mine compares. Of course weather comes into it, but hopefully this will be a useful guide.

November saw solar generation decline as winter approached. Battery management and the Cosy tariff helped reduce costs despite low sunlight, with some days costing as little as £2.08. Hopefully this overview is a useful guide to winter performance.

Upgrading your smart home doesn’t have to be stressful.

With just a quick firmware update and a guided setup in Home Assistant, every device reconnected within seconds.
