I will try it, but let me explain why I came to name the aggregation type
that way.
"integral" is just the opposite of "tderiv", which is available somewhere.
So it seems to me not that special.
But why not name it just "integral"? Because you need a separate entry in
agg_group for each unit label. The principle is always the same: time is
added to the unit. But it is not possible to express that in agg_group on a
general basis.
Integration over power to get energy is not only useful for sun radiation,
but also for the measurements of solar power plants. So I saw it not that
special for that reason, too.
