Using solar W/m2 to determine solar panel efficiency

Hi - I am looking at using the Tempest to get [Screen Shot 2020-09-23 at 1.28.57 PM] Solar power in W/m2 and compare it against the W that my panels are producing. My panels are exactly 1m2 and 170W, or 170W/m2 per panel, of which I have (9). I’ve made sure my load will pull as much solar as possible (drawing from battery too) and noticed that the panels and the tempest are almost the same. I would think that if the Tempest is reporting 500W/m2 and I had (3) panels perfectly oriented I would b…

I found it because I remember seeing this discussion and used the search magnifying glass to locate it.
