After you create your project, you need to identify the location where you would like to place your modules. For rooftop solar, this is done by tracing an outline of the roof that you will be designing solar for, and then using Aurora's algorithms to convert that into a 3D model.
If at anytime you feel stuck, please contact support with your question, and we will schedule a private training session for you.
Modeling the Roof
First, in the project sidebar on the left, click on Site Model and drag the green icon to the center of the house, or close to an edge facing the street (if applicable).
Outlining the roof
We will now begin to draw the roof.
- From the sidebar on the right, select the SmartRoof button to mark roof edges.
- Move the crosshair to the top left corner of the building. Click to place a node.
- Continue to place nodes sequentially at any corner. After clicking on the first node, move your mouse down and click to place a node at the intersection in the bottom left. Repeat this process for all corners
If you make a mistake, click on the node and hit delete on your keyboard, or you can hit ctrl + Z (⌘ + Z on Mac) to undo the action. To continue drawing, return to the last existing node and double-click it.
- To complete the perimeter, hover your mouse over node 1 and click on it to complete the roof shape.
Creating roof structure
Once you are done with drawing the roof edges, double click outside of the roof on the screen. Aurora will intelligently structure and apply azimuths or any rooftop setbacks you have preset to your model.
Adding obstructions and trees will help model how these objects might create shade that impacts your solar designs over time.
- In the 2D view, click on the Add Obstruction button in the sidebar on the right. A submenu will appear showing you the types of obstructions you can add:
- Choose the Rectangle option in the submenu.
- Move over to the chimney on the roof and click and drag a rectangle around the area.
- Repeat for all other obstructions
- Click on the Draw Tree button in the sidebar on the right.
- Place your cursor on the center of the tree and click and drag until the circle is approximately the same size as the tree in the satellite image.
3. Repeat this for all nearby trees
You can select a tree and use ctrl + C and ctrl + V to copy and paste it as well.
After you have completed the 2D drawing, you can easily convert it to a 3D model.
The 3D model is essential to obtaining accurate roof slopes for system design, and accurate site characteristics for remote shading analysis. It's also a huge hit with customers who want to see what their house will look like with solar.
Converting your 2D drawing into a 3D model
- On the top of the screen, click on Adjust 3D Model.
- Click on the Street View button at the top to view the site you are conducting a remote shading analysis on.
- Click on the white arrows in the Street View to walk to the side of the building, similar to Google Maps.
- Building height: 2 stories
- Chimney height: 4 feetChange building heights by clicking on its walls, and entering your desired height in the pop-up box. For the sample project, enter the following characteristics:
- Modify tree characteristics by clicking on the tree and inputing your desired tree height and shape into the pop-up box.
- When you are done, click the Save button in the top left corner.
