All you need is the small plastic dome with the latitude specific sun diagram underneathe it to determine when any objects will block the path of the sun. You can even trace the shadows on the sun path diagram for a permanent record, and use it in conjunction with the included location specific information to determine very specific information regarding efficiency (solar insolation) percentages and power production (kWh/m2/day) on a monthly basis.

The Solar Pathfinder™ is the only instrument on the market that can give an entire year’s solar potential for a given site in one five-minute sitting. This non-electronic instrument is ready-to-use upon receipt of shipment, and comes in a handheld or tripod based unit. It also comes with:
