2 – Insert solar panels (Skelion tutorial)

 

Insert panels The Insert components: button opens 3 dialogs depending on the selected objects, Let’s start selecting an edge and a face. The edge can be a border or any other edge.

 

In the same plane There are 2 conventions for the azimuth, 180 or 360.

 

Let’s begin with the following values: We choose a relative tilt of 35 and click outside of the box to obtain the real azimuth and tilt of the panel.

 

The test panel width is 0 50m.

 

The gap is equal to zero.

 

We choose the landscape orientation.

 

Lets assume your own pitch is equal to 0 7m and click on fill, face Skelion inserts components, row by row following the selected edge in the direction most similar to North opposite in the southern hemisphere.

 

We can check the values using the measure tool and see that the pitch is correct.

 

With the protractor we can mesure the relative tilt 35 as we determined earlier.

 

If we click on the PSI symbol, a new window shows the azimuth and the tilt of any surface. We can select any face.

 

We must take into account that a surface has 2 sides and the tool always calculates the orientation of the positive white side.

 

We can see in this case that the dark side is in front and the white one behind so that’s the reason for the different orientation values.

 

Now we will use a pitch depending on the shadow clicking on the blue, insert component button.

 

Let’s take a pitch that is equal to the shadow cast by the panel on the solstice at noon and click on fill face.

 

We can verify if the shadow and the distance are correct for that date To put the panels coplanar.

 

We only need to insert a relative tilt of 0 To have space between the rows.

 

We must set Your own pitch equal to the width plus the space we want.

 

If we choose another pitch option, the space between the rows will be zero because coplanar panels, don’t cast any shadow.

 

Let’s see now how the fill in rows option works. For example, we set the tilt at 35, choose any of the pitch options and click on fill in rows.

 

Skelion will draw a row at any point on the face.

 

We click at but mantain the pitch distance.

 

If we click close to the last row or just at the point, if we click further than the pitch distance Here, we can see the effect of the use of the option.

 

Row, alingment Stack components, piles up components in the same row, Its not a good option for ground power plants because it slows down the calculations.

 

Gap vertical allows you to create a corridor between n columns and Gap, horizontal between n rows.

 

The Portrait option turns the components, Skelion inserts components, row by row from South to North, Independently of the the mode portrait or landscape.

 

We select several faces and open the Multiple faces.

 

Dialog For coplanarity.

 

We insert the relative tilt of 0. The panels will follow the steepest direction.

 

The space between the rows can be adjusted using X, extra space or introducing your own pitch On this face.

 

If we want to start inserting from the bottom, we can use the one edge one face, dialog and change direction.

 

We must geolocate the model to have real shadows In the menu point Window, choose model info, then geolocation and click on set manual location By default.

 

The model is located in Colorado With the add location button or using the google toolbar.

 

We can use google maps to geolocate the model.

 

Let’s choose Tokyo.

 

We select an area an now.

 

Our model has real shadows in Tokyo.

 

We have a small problem. The image is a bit rotated.

 

This is because the true north does not coincide with the green SketchUP axis, With the solar north plugin for SketchUp pro only we can see the difference Using the button rotate north.

 

We move the true north to the green axis, because Skelion uses it as true north With the green button beside it, you can undo the alignement if necessary, .
