Good afternoon, 

I am wondering, does PV*Sol take into account summer time (or Day Saving Time)? Or does it use only the winter time throughout a year? In that case, daily power diagram in summer months should be moved one hour forward to correspond with the actual time, doesn't it?

Thank you, 

Lenka

Dear Lenka,

in PV*SOL we don't display the DST in our results. That is, when you see a time stamp saying August 13 16:00, it means that your watch would show 17:00 if you are in a region with DST (like Europe for example).

That is what we do, correct.

We decided not to move data in the diagram. The reason is that you would create a data gap of one hour when the time switches from winter to summer, and you would have an overlap of data in autumn, when you switch back. And additionaly the DST rules can get very complex around the globe, so we decided to provide standard winter time.

But yes, if you read the diagrams, the time stamps in summer must be moved one hour forward.

Kind regads,

Martin
