Out in our meadow beyond the vintage apple trees planted by Irish immigrant potato farmers named Sullivan over a century ago, Don Lessard set up a tripod topped by a round sheet of curved graph paper under a plastic globe. We could see the nearby trees and hills reflected upside down in the globe, and Don traced the shadow lines on the graph paper as he said, “This is a great spot for a solar panel!” He then sent the graph and our energy use information to his son Ambrose down in Lansing, and from GPS data and records of sunshine in Leelanau County recorded over many years, they calculated the size of the solar panel needed to produce the kilowatts we require to cover our annual electric needs.
