SunSite: Solar Shade Survey

Full shade survey from the ground: monthly solar access %, Sun Map heatmap, and a client-ready PDF — fully offline. 7-day free trial, every feature included.

Pro shade reports from the ground. No ladder. No drone. No $2,000 tool.

SunSite turns your iPhone into a complete on-site shade survey kit for residential solar. Stand in the yard, capture the skyline, and hand your customer a measured report before you leave the driveway.

BUILT FOR THE PEOPLE WHO WALK THE PROPERTY Small residential solar teams, surveyors, and sales reps who still believe the site visit is where deals are won — and disputes are prevented.

MEASURE FROM WHERE YOU STAND • Crosshair capture: sight each tree, building, or pole through the camera. Shaded hours turn red on the live sun-path arcs. • Sun-calibrated compass: SunSite corrects magnetic heading against the sun's known position, so readings hold up next to steel and vehicles. • Satellite-map distances: two taps replace the tape measure. • Virtual viewpoint reconstruction: measurements taken on the ground are rebuilt at array height — feet stay on the driveway.

REPORTS THAT CLOSE • Monthly solar access % with an annual skyline chart — December tells the story summer hides. • Sun Map: a measured heatmap of sun zones across the roof. Annual and December views, side by side. • Satellite-annotated site page with numbered obstructions. • Export a clean, client-ready PDF. Your data leaves with you.

BUILT FOR THE FIELD • Works fully offline — capture, compute, and export with zero bars. • No account, no cloud requirement, no per-report fees. • Your company name on every report.

METHODOLOGY YOU CAN POINT TO SunSite uses the industry-standard NREL solar position algorithm, sun-based compass calibration, and ground-to-array-height skyline reconstruction. Every figure in the report traces back to a measurement you took.
