SunCheck: sunlight and shadow map for home buyers

SunCheck is a free interactive property sunlight tool by ReraTracker. Search for a home, compare all 12 months, adjust the time and see likely sun and shadow directions before scheduling a site visit.

What can SunCheck help you compare?

• Lower winter sun and longer shadows
• Higher summer sun and shorter midday shadows
• Morning, afternoon and evening sunlight direction
• Estimated shadows from buildings you place on the map

SunCheck uses open-sky solar geometry. Trees, terrain and buildings that you have not added are not automatically modelled.
