) Add a skyline - all those things that will stop direct sunlight from reaching you - buildings, trees, towers and the like.

As the Solar Pathfinder works on a reflective principle instead of actually showing shadows, it may be employed anytime of the day, anytime of the year, in any sort of weather. Even the position of the sun at the time that you conduct the analysis isn’t important. In fact, the unit is easier to be used in the lack of direct sunlight. You can also use it at night, provided there’s enough moonlight to see by.
An essential part of the Solar Pathfinder is a clear, hard plastic dome set on top of a solid base ( the instrument’platform’ ). You look down onto the dome and see a panoramic view of the site reflected on the dome’s surface. Then, a paper sun-path diagram, showing the sun’s route thru the sky for every month of the year and every hour of the day, is placed underneath the dome. Slots in the side of the dome let you trace the outline of the reflected difficulties onto the diagram, revealing exactly what obstructions will shade the selected site and when..
