If the system size on your Aerialytic Design is not calculating correctly, here is how to fix that.
This is commonly seen when the panels on the image are toggled on or off before the initial design loads, or faster than the program can recalculate.
Open the design card and select the Optimal Panels Icon on the left hand side of the design image. This image looks like a ground mount or a solar panel.
This will reset the panels to 0 and the system size to 0.
If you select the Icon again, it will fill the design with the systems optimal placement.
The system size should now be correct and you can toggle on and off panels as you would like.
Click save in the bottom right hand corner.
