How it works

Find the property on the map
Compare photography and viewing times
Explore seasonal sunlight with buyers

Turn “a sunny property” into a useful conversation.

Morning light on a façade, evening light on a balcony and winter shade in a garden are different selling points. Check the exact part of the property and the relevant season before describing its sunlight.

Schedule listing photography

Compare sun direction relative to the façade and outdoor spaces. Discuss front, side or backlight with the photographer, then choose a visit time that suits the intended images.

Prepare for buyer questions

Explore how neighbouring buildings and terrain affect outdoor sunlight. Use AR during the viewing to relate the sun path to windows and balconies, without treating it as an indoor lighting simulation.

Explain seasonal differences

Compare the same location on winter and summer dates. Distinguish a prediction from an observation, and record the date and time whenever sharing a sunlight example with a client.

SunCast does not measure indoor brightness or certify sunlight hours. Map coverage, window geometry, vegetation and weather affect what buyers will experience; verify material claims on site.

Street View Sun Path

Overlay the sun’s path on a Street View panorama to scout the light at a distant location before you visit.

Check where the sun will appear in the scene at your planned date and time, then arrive with a clearer idea of your shooting or viewing angle.

Terrain Shadows

See realistic 3D shadows cast by hills, ridges and valleys as the sun moves across the day — not just a static shaded-relief map.

Explore a future date and time to see when a valley falls into shade, when a ridge blocks a view, or which slope catches the first light.

FAQ

Frequently asked questions

Can I check sunlight in an apartment before renting?

Yes. Stand in the apartment, point your iPhone, and see the sun's path for summer and winter. Find out if it gets morning sun, afternoon light, or stays in shadow most of the day.

Can SunCast show where the sun will be on a future date?

Yes. Pick any date — past or future — and any location, and SunCast shows the full sun path, sunrise and sunset times, and shadow positions for that moment.

How accurate is the sun position?

SunCast uses precise astronomical calculations — accurate enough for professional photography, architecture, and location scouting. The sun moves gradually enough that results stay consistent across an entire neighborhood.
