Introduction

These charts are only available if the station has a solar sensor for measuring the solar radiation.

The Solar charts submodule consists of four charts:

  1. Solar hours statistics - Plotting the range, average and estimator for the standard deviation for the solar hours per year
  2. Monthly solar hours statistics per year - Plotting the range, average and estimator for the standard deviation for the solar hours per month per year
  3. Insolation statistics - Plotting the range, average and estimator for the standard deviation for the solar energy per year
  4. Monthly Insolation statistics per year - Plotting the range, average and estimator for the standard deviation for the solar energy per month per year

Below you will find an example image of each chart and an explanation of the origin of the numbers. For the insolation graphs the method of calculation is explained.

For the calculations the standard C# LINQ-functions Min, Max and Avg are used. For the standard deviation this LINQ-extension is used with a modification for a minimum number of observations required of 2, if less the StdDev returns 0 (zero).

NOTE: for years where no solar sensor was present the chart displays the value 0 on all charts. The possibility not to display the years at all has not been implemented.

Solar hours statistics

Solar hour statistics per year

For all days in a year the value of field 25, Total hours of sunshine (see Dayfile), is taken and the resulting statistics are calculated and plotted.

Monthly solar hours statistics per year

Monthly solar hours statistics per year

For all days in a month in a year, the value of field 25, Total hours of sunshine (see Dayfile), is taken and the resulting statistics are calculated and plotted.

Insolation statistics

Insolation statistics per year
