In the early 1970’s, an oil embargo and a developing earth-friendly attitude prompted the creation of solar tax incentives.

This produced a blossoming solar market with a promising future. This “new” market stimulated many inventive ideas, one being the Solar PathfinderThe Solar Pathfinder is the professional PV installer's tool for determining the most economical and efficient photovoltaic array location and position.
