How Drones Make Solar Panel Inspection, Installation, and Maintenance Easier
Before the installation occurs, drones can be used to survey the entire area. A drone survey will indicate which areas are going to be in the sunlight most often, thereby impacting the efficiency of the installation.
If using photogrammetric imaging, the drone will take a number of photos from above and derive 3D data from that. If using LiDAR imaging, the drone will use a laser to create highly accurate 3D plots that can be used for simulations.
