History

PV generation & consumption graph for today.

Can get a good idea what the weather was like by checking the records.

Good day today except between 12:00 and 13:00.

The 520 watts of power we had to "buy", is the accumulation of lots of little surges.

Used electricity keeps frightening me until I remember it includes hot water heating from the immersion heater. There is also a marked tendency to use electrical equipment during daylight hours that one would otherwise not have used or at least sparingly, eg tumble dryer.
