Array-o-matic Free Solar PV Layout Tool Beta

Need a roof pitch measurement?
Our free Roof Pitch and Azimuth Tool quickly measures solar array orientation using Google aerial and Street View images.

The Array-o-matic is a simple tool for residential solar system sizing and creating a preliminary solar layout on a sloped roof.

Instructions

The following tutorial assumes you have a basic familiarity with SketchUp and know how to use the Select and Move tools. You don't need to be an expert but if you're new to SketchUp, we recommend you check out these excellent video tutorials before you proceed.

Open the Component Options window. Select your module. Select your tilt and orientation.
To begin, right-click (context-click) the Array-o-matic component and select Dynamic Components then Component Options.
Select your module. If your module is not listed select Custom and enter the length and width.
If you're modeling in 2D (faster), select your module orientation: portrait (vertical) or landscape (horizontal) and tilt angle (roof pitch).
3d vs 2D modeling options Switch to the Guides scene. Add an image of your roof.
In 3D mode, the module is kept full size. In 2D mode, the module is shortened to match a top view. If you have a 3D model of your house, set the mode to 3D and disregard the two 2D options.
Switch to the Guides scene tab for easier modelling. This will allow you to see roof geometry and obstructions in the following steps. You can switch back when you're done.
Select File > Geo-location > Add Location or click the Add Location icon to import an aerial image of your roof.
Align the axes as follows: Cut the Array-o-matic component, select the Axis Tool, click the 3 points indicated above, and Paste the Array-o-matic.
The Array-o-matic should now be aligned with the building axes like this.
To align the building with your screen, zoom out, right-click the red or green axis line and select Align View. Hint: you must click outside the image area.
Update the scene. Scale Explode the Array-o-matic.
Right-click the Guides scene tab and select Update. This will save your axes orientation.
Use the Scale Tool to stretch the Array-o-matic to the size of the roof.
Right-click the array and select Explode.
Move modules to fine-tune the layout. Click the Module frame scene tab to show modules Set print quality
Use the Move tool to fine-tune the layout.
Click the Module frames scene tab to show the modules and hide the axes.
For best results when printing, resize your SketchUp window so your house is tightly cropped within the window. Download PDF of the output created in this tutorial.
Component will automatically glue to faces in 3D model. Bonus tip: If you're working with a 3D model of your house, use this technique to quickly orient the array to your roof face.
  1. Select Window > Components.
  2. Make sure you're looking at the In Model component list.
  3. Select Array-o-matic.
  4. As you move your cursor over the model, the component should orient or "glue" itself to any face you select.
