Total Solar Radiation Calculation

Hello everyone!,
I’m optimizing a form for minimum solar radiation, so I need to plug the total value into the evolutionary algorithm…
However, as you can see in the following photo, the total output gives 4.7 KWh which is unlogic for the scale of a building! but when I tried to calculate the total manually by using the multiplication of areas with the provided results on each point, it gave 4777370 KWh

So my question is… why does the total outputs such a small value?! and is the method I’m using to calculate the total manually right? or I’m missing something here?

Thank you so much!

Hi.

The results are given as kWh/m2 per grid point. So what you are doing is multiplying the result per grid point with the area, and then summing that.
