Everyone needs a little direction in life. Statements like that are often philosophical and refer to things like career paths, academic choices or family decisions. But sometimes the question, “What direction?” has very practical applications. If you’re taking a car trip, you’re going to need a GPS or a map to figure out what direction you’re heading. When you book a hotel, you might want a room facing in a particular direction to bring in or keep out sunlight. GreenLeaf Solar also wants you to know that the direction of sunlight has an obvious impact on solar panels and the question of knowing which direction your panels should face is a question we often hear.
