ThingSpeak user, “SolarInKrimpen”, from Rotterdam, Netherlands, created a solar power monitoring system that reports data collected by solar panels and feeds the data to web services such as ThingSpeak, Cosm, and PVoutput. They are collecting data such as, AC Wattage collected by a Pulse Counter, Totak KWH per day, temperature of the solar panels, and the carbon offset.
Take a look at the data in real-time from ThingSpeak Channel 2871:
We also found a video showing the system in action in super hero fashion.
Over at the Netduino forums, we found the source code for the Netduino and HTML for the ThingSpeak gauges for embedding the solar panel data on a website. Awesome!
