Where the sun comes from, which facades it reaches, how long the shadows of the neighbouring buildings are, and how much solar energy the site receives over the year. MapToNap computes it for the exact latitude of your site and draws it over the real buildings around it.
Solstice and equinox arcs with hours, drawn on the site plan for its latitude, with the orientation of the site.
24 hours of real sun and shadows from the surrounding buildings, plus a sun-hours map of the site.
Solstice sun paths, the sunlit facades and the prevailing winds over the 3D context.
Monthly shortwave solar radiation on the ground (MJ/m² per day) from NASA POWER, averaged over 2014–2023.
A simplified feels-like map in sun, shade and wind for each season, marked as an estimate, not a comfort model.
Every sun drawing uses the same graphic language as the other site analysis sheets, so the board reads as one.
Untouched exports from real sites. Free drawings carry a watermark; Pro and Max drawings are marked.

A sun path diagram shows the path of the sun across the sky for a given latitude, usually for the solstices and the equinox, with the hours marked. Drawn over a site plan, it shows from which directions and at what height the sun reaches the site.
You need the sun position for the date and time and the heights of the buildings around the site. MapToNap takes both, from the latitude and from OpenStreetMap building heights, and draws the shadows for a full day in Deep Analysis, or the sunlit facades in the sun and wind axonometric.
From NASA POWER, a global dataset of daily solar radiation and weather from 2014 to 2023, averaged by month for the coordinates of your site. It suits site analysis; for engineering-grade daylight certification use dedicated simulation software.
Yes. Sun paths are computed for any latitude, so the drawings are correct in Sydney, São Paulo or Cape Town as well as in Europe or North America.
You can try MapToNap free: four 2D drawings (roads, land use, green and water, urban fabric) and one 3D drawing, with a watermark and no sign-up. Without the watermark and with all 68 analyses there are one-time passes: Pro €7.99 or Max €12.99 for 30 days, or a year of Max for €49. Nothing renews automatically.
No installation and no setup. MapToNap runs in the browser on any computer, tablet or phone, iPhone or Android: open maptonap.com/app, type an address and press Generate. 3D drawings and simulations run smoothest on a computer.
