What is a Solo Shade Report 

The Solo Shade Report provides a detailed analysis of key site attributes that impact the production of a solar system. Data including TSRF, TOF, Solar Access are uniquely visualized for the site - allowing AHJs and other governing bodies, as well as property owners to better understand the level at which a system will produce.

The shade report will consist of a summary page detailing the average data for the system as a whole, and individual array details pages covering the shade analysis for each array.

For a walkthrough on creating a shade report for one of your proposals, visit our step-by-step article HERE. 

Please Note: Access to shade reports can be controlled by owners in their MissionControl portal. Owners can learn more HERE.

 


Where and How does Solo get the Data for a Shade Report?

To create Shade Reports, we start by collecting imagery data from the homeowner's location. We work with partners like Nearmap, who provide aerial images of the property. These images help us understand the layout and structure of the home and roof. Three main types of images are used:

  1. Ortho Image: This is a straight-down, true overhead view of the house. It's a clear, bird's-eye snapshot of the property.

  2. Vertical Image: This image shows the roof from a straight, non-angled view. Of all the images taken, we choose the one where the roof has the least tilt for accuracy.

  3. DSM (Digital Surface Model): This image pairs with the ortho image, where each pixel has its own elevation value, showing the height of objects like trees or buildings around the home.

Once we have these images, we use the DSM to create a 3D model of the house and the surrounding area. This model allows us to determine the tilt and direction (azimuth) of each roof surface, ensuring everything is accurate.

Then, we simulate the sun’s movement across the sky throughout one full day for each month. This helps us see how much sunlight each part of the roof gets at every hour. The simulation then answers the question, “Can this spot on the roof see the sun?” with either a True or False answer. Once the system is designed, pixels under each solar panel are aggregated to determine shade for each panel.
