The photovoltaic solar installation that I must design is located in different buildings, which are separated from each other. 
These buildings are located in a valley, that is, surrounded by mountains except the south. 
After calculating with an inclinometer in the place and noting the angles of height of the horizon, I have introduced them in the pvsol. 
But when calculating the shadows does not take into account the horizon, what should I do to take into account that horizon that I have manually introduced?
Thanks and greetings to all who are PVSOLERS, hehe
pd: Great photovoltaic design program, to say the best.

Hello Gorka,

Thanks for the compliments, we're glad to hear that.

If the horizon line affects the installed pv modules, the horizon line is accounted for as "Yield Reduction due to Shading".

 

You should also be able to see the horizon line, otherwise something has gone wrong.

 

I hope these information already helps,

Kind regards

Marcel
