I am curious as to what others are getting for real live solar system performance. I have a Victron 100/30 MPPT Controller with a "dongle" that communicates with an app on my smart phone that acts as a solar system performance monitor. I understand that the Victron charge controllers now can come with this bluetooth monitor built in. At any rate, this is a very useful monitor which you can use to monitor your solar system performance.
I have four 120 watt Solar Cynergy flexible solar panels on my roof, for a "nominal" or theoretical maximum of 480 watts of production. We all know that it is almost impossible to get the maximum production from solar panels mounted flat on your roof. But how close do you all come? I know it varies according to the time of year, time of day, weather (cloud or clear), temperature, etc. But I would be interested in having whoever is interested post their real life solar system performance here.
Heres my reading for today: 480 watt Solar Cynergy flexible panels. Jan 26th in extreme southern Utah (near Arizona border). Clear sunny day, 50 degrees. My system monitor says I got a PV maximum today of 210 Watts. 210 / 480 = 44%.
So today I got 44% of my theoretical maximum performance. I guess this is OK, given the time of year. One thing I am testing by the way is to make sure all my panels are performing properly, since a few months ago I damaged them driving into the garage. Also, I noted today that my panels were somewhat dirty. I plan to clean them and measure again tomorrow.
