Displaying the results

We have a Schuco hand held display that picks up a wifi signal from the inverter in the loft. This shows the amount being received at that very moment, plus a graph of how it has varied between sunrise and sunset.
Even when cloudy, you get power so long as the sun has not set behind the clouds. They get no power in the daylight period after sunset.
The handheld unit shows the whole month at a glance, revealing a weather record of sunny and overcast.
This moment here shows the situation at 0920 on Oct 2nd with 1.4kWh already harvested under a cloudy bright sky.
