The Solar charts submodule consists of four charts: | The Solar charts submodule consists of four charts: | ||

#Monthly solar hours statistics per year - Plotting the range, average and estimator for the standard deviation for the solar hours per month per year | |||
#Insolation statistics - Plotting the range, average and estimator for the standard deviation for the solar energy per year | |||

Below you will find an example image of each chart and an explanation of the origin of the numbers. | Below you will find an example image of each chart and an explanation of the origin of the numbers. | ||

For the calculations the standard C# LINQ-functions Min, Max and Avg are used. For the standard deviation this [https://stackoverflow.com/questions/2253874/standard-deviation-in-linq 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. | |||
