I am gathering a few pieces for my (hopefully) small, easily portable, and capable DIY solar gen/power station, while I wait on 100ah cells. I bought a fold up Rockman 120 watt panel that I wanted to test. I used my kayak battery and its remote screen monitor.

I was pretty impressed with the panel output on a winter afternoon with a covering of thin clouds. The Rockman stayed in the neighborhood of 100+ watts for several hours. I was also pleased to see my hall effect sensor was sending similar numbers to the remote screen, as the Victron app. The biggest variance was the actual batt voltage.
