I am trying to recreate in Microsoft Visio a diagram of a photovoltaic power plant that would look like the one below.

But I have some issues for doing so, in particular : 

* I don't know how to create a "grid" symbol like the one that is at the bottom right of this picture
* I don't know how to make an "abbreviated line" with tildes like the ones you can see Inside the PV modules at the extreme left of the picture.

Can someone give me some help with this?
