Doug Sabetti, owner of Newport Solar, offers potential customers a free site analysis.
The Newport Solar Web site notes, "There are many factors that affect the feasibility and efficiency of a solar array. Building orientation, panel tilt angle, electrical panel size, roof geometry and tree shading are just a few of the variables that we look at while designing a solar system...When we do a Site Analysis we gather a lot of data."
Some of that data is not so easy to gather when the roof in question is covered in snow and ice, made of slate. or just really steep. The S910 changes all of that, plus it takes a lot less time to hit two points with a laser than it does to physically run a tape between them.
