Rather impressed to hear the solar panel working today, New Year’s Eve, on a grey, overcast day with no hint of sun.  It ran for less than an hour so if I hadn’t heard it, it wouldn’t have been recorded in the stats.

Since it started working in September, its mini-computer calculates that it has generated 385kW of heat for the hot water tank.

Using Nottingham Energy Partnership‘s energy ready reckoner, that’s about  £10.72 worth of gas.  We will have to see how well it performs when confronted with an actual summer.
