Hi everyone. You may remember me posting about my Instromet sunshine recorder. I am pleased o say that everything as worked out well I now have their data logger and its working perfectly. Here's the output. Thoroughly recommend their logger and new software in Excel. If interested in the output please get back to me. Whilst I am on the subject of sunshine records, has anyone got any good links to sunrise /sunset tables for any particular day for a given lat/ long. I am trying to work out the percentage of sunshine per day against the maximum possible. The Blake Larsen sunshine recorder is my ideal output, but I didn''t go down their route as their system/software requires your computer power 24/7.
