I think I have a problem but cant find anything wrong with my setup. Here in the UK it is 08.50am just a tad under an hour after sunrise which my VP says was 07.57. The current WD max value for this lat/date is reading 0. Now no way can this be correct. It must now be more than 0. I have my date and time correct on my PC, in WD and in the VP - all double checked. I have my lat/long set correctly in both WD and VP - 01.26.25E 51.21.48N. I do NOT have daylight savings ticked and the minute offset is set to zero. It just seems to me from observing the values yesterday that WD is about 1 hour behind, as it maxed out yesterday at just after 13.00hrs surely an hour after solar noon! At 09.02 this morning WD just calculated a value of 1 w/m2 for this lat/date!
Can someone suggest if it is me or is there a bug in WD?
