How to create a string layout
This guide explains how to create a string layout in app.solar.
Create a customer
Go to the customer list and press create customer, or choose an existing customer. Fill in all details such as address, city, first name, and last name. Then open the Products tab to choose a solar panel under Roof components. If you already know which other components will be included in the installation, you can add those as well.
Create a string layout
Once the customer has been created and filled in, it is time to create a string layout. Go to documents, press Create system document at the top of the table, and choose string layout from the menu that appears.
After creating the string layout, you will enter the editing view. The icons in the upper-right corner are explained below.

When this mode is active, drag the mouse while holding the left button to add panels.

When this mode is active, right-click panels to remove them. In any mode, you can always select a panel area and shrink it to remove panels, or remove individual panels with a left click.

When this mode is active, drag across added panels to add the string route. Drag in the intended order of the string, from minus to plus. If you need to redo a string, start where the string should begin. You can also press the mode button to add and switch between the selected string.

When this mode is active, click panels to add optimizers. You can also press the mode button to add optimizers to all panels.

When this mode is active, you are only controlling the reviewer view. You can drag across panel fields with the left mouse button without risking moving them.
Draw your panels, create and draw the strings, and add any optimizers. Then press Save and exit. A PDF file will be generated in the background and becomes available shortly after you save the string layout.
