The theoretical max is for sun on a completely clear day. When there are clouds and the sun goes in and out from behind them, I see values over theoretical max. But I never see that when it's clear. > I see this on two different stations in two different places, so I doubt it > is my station. > > Does anyone know how to adjust this max or have another recommendation? Don't adjust: I suspect it is right. My recommendation is to accept that with a cloud edge as a lens, there is a temporary focusing. Now, actually looking at your data, things are not making sense. Are you graphing the max radiation in a 5 min archive interval, or the average? Your graphs look peaky and irregular and when looking at average (non-Belchertown) I tend to see a nice approximation of a sine wave, on clear-sky days. Today my measured high radiation was 364 W/m^2 (but I'm down south, at about 42.5). 527 just doesn't seem right. I see values like that at times, but mostly around 250 these days. Also cross check your console vs weewx. > Or have I unlocked the secrets of the universe? I don't see hwo to turn this into a perpetual motion machine.
