# How can I model an east-west panel layout?

To model an east-west panel layout, create a flat roof or ground mount area in [any design mode](https://help.easy-pv.co.uk/books/buildings-and-roofs/page/choosing-a-design-mode "Choosing a design mode").

In the panels task follow these steps:

1. **Add panels** to the roof/area and then **select 'No mounting'**
2. Set the direction to **east-west** and configure the spacing as needed [![image.png](https://help.easy-pv.co.uk/uploads/images/gallery/2025-11/scaled-1680-/3wfX4yjO6sAiK0AN-image.png)](https://help.easy-pv.co.uk/uploads/images/gallery/2025-11/3wfX4yjO6sAiK0AN-image.png)
3. Select option 1 to fill the roof/area with portrait panels, option 2 to fill the roof with landscape panels and 3 to clear the roof [![image.png](https://help.easy-pv.co.uk/uploads/images/gallery/2025-11/scaled-1680-/Fifwh6FaWO87Cqi3-image.png)](https://help.easy-pv.co.uk/uploads/images/gallery/2025-11/Fifwh6FaWO87Cqi3-image.png)  
    Or drag and drop portrait (right) or landscape (left) panels to build panel layout

<p class="callout info">This will not spec the mounting components but will mean the pitch and orientation of the panels is correctly modelled in performance calculations. Get in touch with [Midsummer (UK)](https://midsummerwholesale.co.uk/) / [(IE)](https://midsummer.ie/) for guidance on mounting components. </p>
