Module Specific Partial Shading

[Ahmad Elghobashy]

In the simulation results, can someone please explain the physical meaning of the module specific partial shading

and is there a way to present a graph that would show the shading losses during one day (best 21st of December) ?

Hello Ahmad Elghobashy,

the "Module-specific Partial Shading" are the losses due to shading on the specific module. This means that these are shadow losses due to trees, other buildings, etc., which have a negative effect on the i-v-curve of the respective module.  To illustrate the negative effects on the i-v-curve, simply activate the "Record characteristic curves fo r MPP tracker modules"  simulation option under Options > Project Options > Simulation.

i-v-curve with shading.

 

 

To see the losses in a graph you could use the "Carpet Plot". Simply select the data series "Module Area Name: Losses due to shading".

 

 

 

In addition, you can display the position of the sun (solar altitude) in our 3D-visualization. To do so, click on the sun at the top of the program (red frame in the picture).

 

 

Kind regards,

Marcel

I have 2017 version, is it different than 2018?

I can't find Record characteristic curves for MPP tracker modules  tick box

Oh, yeah, sorry I forgot to mention it.The i-v curves are one of the new features in PV*SOL 2018, such as the import of different 3D models or polystring configuration. Details can be found in our Release Notes.
