Bifacial Module Simulation with different tilts & azimuth

[sajid s46]

Hi 

Can you pls explain how to simulate for a project which has both rooftop with two orientations and ground mount with BiFacial Module.

Because if im enabling bifacial option in the system, I have to choose unlimted sheds in the orientation and If I  choose unlimited sheds then I cannot define orientations for my roof top system which has different tilt angles & orientations.

Thnks.

To be precise, you could choose either "unlimited sheds" or "fixed tilted plane". However since in your case you would have 3 orientations, you would have to use "several orientations" and that is not compatible with the bifacial model.

At the moment therefore, the only way is to make two different variant simulations, one for the bifacial part, another for the rooftop two orientations

We have the same issue but making two different simulations isn't working for us becouse we need to calculate Solar Fraction SF. Is there any possibility to calculate it using several different simulations?

So far, the only way is to compute it manually. Solar fraction is defined as EUser / ELoad, so you can use the total EUser and total ELoad instead.
