You'll learn how to read the two remaining charts in the project's Analysis section: the wind speed and wind direction rose, and the monthly ground surface albedo averages available under the environmental category.
The other charts cover two parameters that use their own visualisations rather than the standard time-step histograms: wind, shown as a directional rose, and ground surface albedo, shown as monthly averages.
For the other chart groups and an introduction to the Analysis section, see How to read the charts.
Wind speed and wind direction
This chart illustrates the direction and speed of the wind at the location. It is represented by a circle depicting the directions (North, East, South, West) with intermediary directions in between.
Different colors represent different wind speeds (1), and the direction is indicated by its placement within the chart.

Ground surface albedo
The chart represents the monthly ground surface albedo averages for the whole time series and is available under the environmental category only.

How to use it
Albedo values can help you establish the reflectivity of the surrounding area and make more informed decisions when selecting the PV module type.
