Tinkering a bit more with my home grid I wrote about yesterday I found the mobile interface to the new PV node valuable. By either navigating to the device or just touching the socket in which it is plugged, my NFC phone opens the device GUI. It gives the current panel output as Watts in real time. I immediately found it necessary to adjust the angle of my panel to see if it captured any more energy, but it was obviously too cloudy to make any difference. I am, however, pleased to see that the panel is infact producing quite a bit, even when it is overcast. I'll be checking the prognosis more frequently with this tool in my hands.
