(1) Combine up to 4 planes in one API call. Applies to forecast, historic and clear sky data
(2) This is helpful if you have a east/west installation to fetch both planes in one API call
(3) The rate limit is rolling, i.e. not per hour on the clock but per last 60 minutes.
Please note that the forecasts are updated at the earliest every 15 min. due to the weather data used, so it makes no sense to query more often than every 15 min.!
