A new solar PV record day

Today our solar PV installation generated 25.07kWh of electricity, a new record beating the previous high of 21.69kWh.

This is what the graph from my automated data logging looks like:

As you can see there was unbroken sunshine all day although it only peaked up to around 3.1kW which reduced the overall output for the day. We’ve seen the system peak at over 4kW so I hope as we get later into the year we will see higher daily totals due to the higher peak output.

[ An interesting side note to this – our ground source heat pump was only on for 4 hours today, whereas during colder weather we can expect it to be on around 10 hours a day. I assume this is because of the high temperatures during the day and the obvious much reduced demand for heat. Let’s hope this this is a good indication of typical behaviour during the Summer months. ]
