Residential Solar Surveys With Drones: Why You Should Always Include Oblique Imagery

2. Better detect small obstructions

Pointing a camera straight down negatively impacts detecting small obstructions, like vent pipes and attic fans, because the verticality of those objects aren’t effectively modelled. Missing obstructions in your modelling can derail a solar project by forcing a redesign, delaying an install, or negatively impacting customer expectations.

Oblique imagery will better present the X, Y, and Z-axes of a property, meaning you’ll more easily spot obstructions and can plan around them. This might mean a smaller installation, yet you can adjust customer expectations ahead of time to avoid problems on install day.

3. Increase sales using oblique images

Models created from nadir images lack real-world features. Often facades can look melted and the sides of structures blurred. Or worse, a nadir image misses data and yields holes in a model reconstruction. Oblique imagery, on the other hand, can yield truly comprehensive, interactive 3D models. Not only does this help solar designers get more context about the site, the images can be used for marketing and showing customers what the finished project will look like. These to-scale, virtual replica models are sometimes so good that they look like photos of real homes.

Don’t lose on bad data

Installing a solar project is like putting a mini-power plant on your roof. It’s best practice to capture the most thorough details possible. Thankfully, multiple drones (like DJI’s Mavic Pro or Phantom Series, Autel’s flagship drone, and Skydio) now make it much easier to automatically capture oblique imagery. This enables accuracy to within 2-3 inches and clarity to streamline and automate much of a solar project’s workflow.
