Positioning Your Solar Devices

Cleopatra Needle Shadow Down The Well

It is important to note that the position of the sun in the sky changes from hour to hour, day to day, and year by year. While this might be interesting, it is not very helpful to us as prospective solar energy users, as it presents us with a bit of a dilemma where exactly do we point our solar device The ancients attributed the movement of the ball of fire in the sky to all sorts of phenomena, and various gods and deities. However, we now know that the movement of the sun through the sky is as...
