Sorry,i fogot to use English.
Hello everyone, I have meeted some difficulties and hope that friends can answer them.
I built a mountain power station with "shading factor table" as shown in the image. I noticed that some numbers uses blue font. The blue font indicates the back, but sometimes appears as a blue number, such as 0.312 at -80° in azimuth and 2° in elevation. Sometimes, it appears as a blue "behind", as seen at the azimuth of -60° and the elevation of 2°. Below is a diagram of the two monitors. I don't see any difference between the two, but why is the "Shading Factor Table" displayed differently?
