How to Plan Rooftop Solar PV Systems Faster, Cheaper, and More Accurately
Technology to improve the speed, efficiency, and safety of PV system construction is always advancing, with Aerial Planning Surveys as one of the most recent developments. Aerial surveys of rooftop sites enable teams to properly plan installation and remotely confirm project progress. Teams can quickly and safely view obstacles, accurately plan measuring missions and have a precise base inspection map. Read about the solution’s advantages, effectiveness, and deliverables, as well as an industry use case below.
Quickly Gained Advantages
In order for teams to begin constructing a rooftop PV system, there are several developer bottlenecks that need to be overcome. These include finding recent imagery of the roof or a rooftop site survey, gathering measurements of parapets, offsets, and obstructions, accurately plan the PV system using dated imagery to plan the design/layout, and obtaining the necessary permits. Aerial Planning Surveys enable teams to quickly overcome these challenges and move into the construction stage faster while avoiding hazardous man-hours climbing up onto the roof to analyze the site.
Accuracy: When a site is surveyed with a UAV (drone), the measurements of parapets, offsets, and obstructions are exact and remove any potential error encountered by using generic and outdated imagery. This prevents any incorrect initial measurements from postponing or increasing the cost of the construction.
Speed: Aerial rooftop surveying is 75% faster and cheaper than manual rooftop surveying, enabling teams to obtain permits faster. Aerial Planning Surveys also allow teams to be more efficient and inspect more rooftops in a shorter period of time.
Safety: Performing an Aerial Rooftop Survey eliminates the numerous safety hazards of a manual site assessment. By removing the need for engineers to visit the rooftop site it eliminates the risk of injuries.
These inspections equip teams with the technology needed to design the site right the first time and prevent unexpected delays and costs later in the project. The initial design greatly influences the final cost of the project, making an accurate design a key part of an efficient and seamless rooftop PV system construction.
These deliverables are provided with a fast turnaround time, often in less than 48 hours. A turnkey project includes a professional pilot deployed to the site to perform the data collection survey within days of a PO generated. Deliverables arrive shortly after the survey completion to enable construction project progress.
The Deliverables from an Aerial Site Assessment
Upon the completion of the Aerial Rooftop Survey, teams are equipped with multiple files that enable them to properly plan and design the PV system. Deliverables include:
Orthomosaic: An orthomosaic map is a detailed and accurate photo representation of the surveyed area.
Digital Surface Model: The files hold representations of the surfaces and features that are elevated above the ground/roof surface, offering teams precise height measurements.
Point Cloud: The point cloud file is the most complete set of raw measurements of the site, enabling teams to create an accurate CAD model.
Ortho Scale Factor: The necessary conversion factor for all units of measurement in the deliverables.
3D Mesh Files: In this packet of deliverables, teams receive mesh material, the 3D mesh file, and the texture file.
Though all of the above-mentioned files aren’t AutoCAD files, they are AutoCAD compatible.
AutoCAD Files: The AutoCAD file deliverable is available as an upgraded deliverable and provides engineers measurements of parapets, wall offsets to IFC Standards, and rooftop obstructions.
Raptor Maps’ aerial site assessment turnkey services and deliverables enable teams to properly plan the installation and remotely confirm project progress. Aerial inspections are 75% faster and cheaper than manual inspections, allowing teams to obtain necessary permits faster and inspect and survey more sites in a shorter period of time. Teams are able to view obstacles, accurately plan measurement missions and gain a precise base inspection map. The aerial surveys eliminate safety risks and hazards by eliminating the need for manual rooftop visits. Design the site right the first time with precise aerial data and prevent unexpected costs later in the project.
