Utilizing drones for residential photo voltaic: DroneDeploy software program permits Sunrun to conduct roof inspection with out threat to employees
By Jim Magill
Drone know-how is spurring the expansion of one other revolutionary trade, the residential solar energy trade.
Starting in 2019, Sunrun, the main house photo voltaic system installer within the U.S., started working with DroneDeploy to develop a drone-based resolution to the challenges posed by having to ship its technicians onto owners’ rooftops to take measurements, a time-consuming and probably harmful job.
“We have been nonetheless hand-measuring roofs utilizing tape measures. There’s plenty of human error concerned in that,” Paul Helm, Sunrun mission supervisor, mentioned. “Our technicians have been spending upwards of three to 4 hour per web site, which made it actually troublesome to hit the targets we have been setting of a number of surveys per day.”
Sunrun teamed up with DroneDeploy to launch its drone program within the latter a part of 2019, and began constructing its drone fleet with the acquisition of 110 DJI Mavic 2 Professional drones in December of that yr.
“It was steerage from DroneDeploy that landed us on that exact mannequin as a result of it built-in into their platform very well,” Helm mentioned.
Utilizing Drones for Residential Photo voltaic Surveys: From 2 Hours to fifteen Minutes
The corporate now flies about 245 drones and employs the identical variety of web site technicians who’re licensed as Half 107 drone pilots. In its peak month, Sunrun performed 7,000 drone flights recording information on buyer roofs from the bottom utilizing DroneDeploy’s mapping software program. The drone program has decreased the time for web site technicians to finish a survey to a median of quarter-hour versus two hours for manually performed surveys. It has additionally decreased the quantity off points involving the becoming of photo voltaic installations by 35%, Sunrun mentioned.
Helm mentioned that earlier than the corporate started using drones there was an amazing variation within the period of time web site technicians spent measuring a roof. “It might take wherever from quarter-hour on a easy rectangular roof to 3 and a half hours on these bigger mansions in our Texas market,” he mentioned.
DroneDeploy’s software program permits Sunrun to create an interactive web site view of the roof, creating maps, photographs, panoramas and movies.
The software program bundle mechanically takes the mapping information and converts it to a digital file, pulling out the measurements wanted to design a rooftop photo voltaic array, Katie O’Leary, DroneDeploy’s director of product advertising, mentioned in an interview. A digital file of the measurements is then despatched to the designer who can plug the info right into a computer-aided design (CAD) program to create the structure of the deliberate photo voltaic array.
“By not placing somebody on the roof, you’re eradicating that hazardous component out of the equation. You’re now permitting them to remain on the bottom and also you’re getting extra correct and well timed data,” O’Leary mentioned.
The map and mannequin captured through the use of drones for residential photo voltaic additionally offers Sunrun a 3D view of all the home that will be subsequent to unattainable to seize for a web site technician standing atop a roof. This turns into necessary in circumstances the place the designer must see a particular portion of the roof to make sure that the proposed photo voltaic array could possibly be put in in that space accurately, Helm mentioned.
“When DroneDeploy exports their map and mannequin, we now can zoom in on any portion of the roof and see any a part of it as a result of the drone has a 4K digicam, which permits us to get nice element,” he mentioned.
Apart from rising the effectivity of its operation, for Sunrun an important advantage of its drone roof-inspection program has been the impact it has had on the protection and morale of its work drive.
“It’s an enormous win for us and our web site technicians. Measuring a roof manually may be very bodily demanding. It’s mentally hectic, it’s taxing and it’s exhausting,” Helm mentioned.
Earlier than the corporate transformed to drone-based roof inspections, its technicians must climb atop roofs in quite a lot of troublesome circumstances, akin to 120-degree days in Las Vegas, when “the roof is radiating about 150 levels again in your face,” he mentioned. “The morale has gone up fairly a bit as a result of they’re not utterly exhausted by the tip of the day.”
Helm mentioned Sunrun’s adoption of drone-related know-how is barely at first levels. “We’re really simply scratching the floor,” he mentioned. “We see the potential for drones and supporting gear to actually create an autonomous web site survey.”
DroneDeploy has developed a software program service that permits inspectors to do a 3D walk-through of a constructing. Simply because the software program firm’s map and mannequin system permits Sunrun technicians to conduct inspections of rooftops, DroneDeploy’s program can allow the photo voltaic technician to conduct pre-programmed drone inspections of attics and different troublesome to entry inside areas.
“That’s completely life-changing for us. Now a web site technician can simply open doorways for the drone and let it in and fly round,” he mentioned.
“During the last couple of years, we’ve added plenty of capabilities so now we’re actually capturing whole views of web sites or services,” DroneDeploy’s O’Leary mentioned. Utilizing her firm’s know-how, clients akin to Sunrun now have the flexibility to attach with a 360-degree digicam to seize 3D photographs and to create digital twins of inside areas, she mentioned.
