Check out the upper right corner of the middletongreenhome.com main page, and you can see our real-time solar array generation stats!

The folks at H&H solar installed our "Fronius Interface Card Easy" on Monday, which allows real-time querying of the inverter via serial connection. We have a home computer polling the interface for its current power output every 3 seconds, and uploading this data to the website. The day's generation is then calculated from the statistics gathered.
