Yesterday I discovered that the inverter (that converts DC power from the panels to AC for the house) also gives an instant readout of what’s being generated. The inverter is in the loft, so it’s not convenient for monitoring constantly, but I went and had a quick look earlier on:
This is a late September afternoon under a watery sun, making enough to run my dishwasher more or less for free. I had started to suspect a week or so ago that it might be most cost effective to run our dishwasher in the afternoon when the solar panels are busiest, having pondered the difference between what it costs us to buy electricity from the grid and what our supplier will pay us for excess solar generation. It is definitely better for us to try to use it than sell it.
So for the last couple of days I have been loading the dishwasher throughout the evening and into the next morning but using the delay timer so it starts around 1pm.
