Solar Power - Monitoring Output
The SolarCity web based monitoring system didn't work at first, there was a problem with the data-logging board in the inverter but they were helpful and sent someone round to fix it. So now we can track how much power we are generating. The graph updates every 15 minutes, and it reports the amount of power every half hour, so when it shows 1.7 KWh that is equivalent to 3.4KW averaged over 30 minutes. So far the highest peak instantaneous output reported on the Inverter is about 4.2KW.
We are still waiting for the energy consumption metering to be added, which puts a second line on the same graph.
The day shown was a typical day up here on top of the mountain, it was cloudy elsewhere, but we had basically clear sky all day. and generated over 25KWh.
