Realtime Photovoltaic Output

I finally got around to switching from MRTG to Cacti for SNMP monitoring… and in doing so, I started to use it for other things that aren’t SNMP based. One of those things is charting electricity output from the solar panels I have at my home…

It’s kind of a fun thing… so here you go. You can see realtime electricity output from my solar panels (updated every 5 minutes).

    How big is your array? Is it ground or roof mounted? Do you use tracking or fixed mounting? Thanks for the info and sharing your impressive output generation data.
