Solar hours and the ChartsCompiler

[HansR]

Reading this interesting thread on Solar Info and especially when it came to @Cambium asking for how to have that info in a chart, I thought how easily that could be done with the ChartsCompiler. So here it is (created during morning coffee).

If you put the next line in the definition of your Solar radiation chart - assuming you use the chart definitions that come with the distribution - you will get the percentage line. If the radiation is above that line, CMX will count it as the sun is shining, so the time will add to the solar hours. You can view an example on my site (see signature, click Solar pane).

Code: Select all

  Plot  Percent75TSM EVAL [ TheoreticalSolarMax * 0.75 ] As Spline LineWidth 1 Colour DeepPink Zindex 10 Opacity 0.2 Axis Solar

Where TSM stands for TheoreticalSolarMax of course. The percentage if what you define personally in the CMX Solar definition under Station. That is your personal tuning of solar, it is not written in stone.

The complete chart definition of what you see is:
