Creating panel layout There are three ways to add panels to a roof:                   Drag and drop  to place panels individually                 Click on a panel and use the  arrow keys to add adjacent panels                   Click auto-fill options to fill the roof with portrait or landscape panels Auto-fill options will avoid obstructions and place as many panels as possible within the configured margin.  To remove panels, you can:                 Double click to remove an individual panel               Shift + Click + Drag to select multiple panels and Delete/Backspace to remove them                   Click the clear roof option to remove all panels   Choosing a mounting system Once the roof has panels on it, you can choose from the available mounting options on the right. The mounting options displayed will be compatible with the roof and panel   size and layout .  When selected, Easy PV will specify the necessary mounting components. Depending on the mounting system, you may also have additional options to configure the components further (rail colour, preferred hook, bird blocker etc.).  This mounting kit list does not take into account structural considerations. Adjustments needed to the number of hooks can be calculated in the structural task (UK only) or otherwise.  If the mounting system you want to use is not available, select No mounting . For flat roofs, you will have additional options to configure the panel layout , including east-west options.  Multiple roofs Use the list on the left to navigate and configure the panel layout for each roof.  Once all roofs are completed click  Next  onto the inverter task.
