Well if there was an issue with low angles, then I wouldn’t be getting 100% or more plotted in the chart??
My sensor sits inside a ping-pong ball which ensures homogenous illumination no matter how low or high the angle is. It’s not perfect, but it serves the purpose.
Can it be a problem with some obsolete setting in the log file, for example? I could post it here if it would help.
That is happening except for early mornings / late evenings. Could you please revise the code whether there is no other condition built in the calculation?
Please look back to reply #3 in this thread. You will find a screenshot there with the captured problem. Facts on the main screen: Snapshot taken at 8:45am (see time), full sun since 6am (see yellow radiation line even over red max solar curve), just 5 mins of sunshine calculated (left top corner). Should be 1:45 instead…
I checked the latest build 8. There is something wrong indeed, check the two screens attached. They are both taken at the same time - 19:30. While the main screen shows 55,4% of solar radiation, debug info just 4% raw! Maybe that’s why it doesn’t add up sunshine hours.
Still no change. Measured a while ago. Time 6:58am, 00:00 cumulative sunshine calculated, 100% solar rad on the main screen, 30% raw in the debug log. Now I think I know where the problem in the math is.
Sunshine hours are calculated just from the raw % which is shown in the debug log. The raw reading in the “Current readings” screen was 21.5 mV which is exactly 30% of the 70 mV I have set in the “Max solar…” setup screen. This 30% is also shown in the debug log and it is still lower than 48% I have set in the “Thresholds…” screen. Shortly said, WD calculates sunshine hours from the absolute max mV, not from the relative % measured during the day.
I notice in the solar setup you have set to use sensor #1 from a labjack…but you do not have labjack sensors…
and you have ticked to use solar from a wh3081 station…but I dont think you have that station type
