Know exactly where the sun will be.
Suntilo shows how shadows from your house, your neighbours' buildings and nearby trees move across your property — hour by hour, season by season, through the whole year.

How it works
- 1. Mark your property
Enter the address and outline your house, neighbouring buildings, trees and fences.
- 2. Add heights
A rough height for each object is enough to get a realistic picture of the shade it casts.
- 3. Read the year
See direct sun hours for any spot, any time of day, any date — with clear recommendations.
