Scouting rooftops with drones for optimal solar panel placement

Solar now is becoming more and more popular as hardware costs decrease, but soft costs like installation and scouting now aren't decreasing as quickly--thus making up the majority of solar installation costs.
One component of the soft costs is scouting for the best place to put solar panels, which is typically done by using a device called Suneye, which calculates the best place to put a solar panel by measuring the amount of sunlight that hits a certain spot. The Suneye device does this by taking a 360 degree snapshot of the sky from a certain point on a rooftop, and then shading in obstructions to the sky like trees or fences. The remaining area, coupled with the position on earth as determined by a GPS device which is used to determine the trajectory of the sun, is then used to calculate the amount of sunlight that would hit that specific point--thus helping to determine whether that point would be a good place on the rooftop to put a solar panel.
The issue here is that scouting for a point on a rooftop to put solar panels is far more expensive than it should be. This is because of insurance costs and manpower required--people are expensive to pay, and insurance must be paid in case roofs are damaged while workers work on them, the workers fall and suffer serous injuries or death, and equipment dropped from the roof and damaged.
Our solution here is to use a drone instead of people with ladders to find the best point to put solar panels. There's a few reasons for this--drones are typically lighter than people (they must be to fly), they don't demand wages, they require fewer people to operate, and they tend to take less time to take data(flying is faster than clambering up a ladder). Thus, drones would be the preferable option here.
There are already drones on the market that have enough power to carry the Suneye devices--or alternatively, carry fisheye cameras to point towards the sky. Using similar software as Suneye would help obtain similar results for a fraction of the cost of hiring workers--though one would still be required to operate the drone. With the FAA's new rules coming out for commercial use of drones, now has never been a better time to use drones to help spread sustainable energy.
