In what is fast becoming a popular column, Ask The Sietch is now on its third question.
I recently got this from Noah
I have been researching solar thermal options and wish to create a solar thermal panel using a parabolic reflective surface, but I am not finding an easy way to create a solar tracking device, either one axis or two. Do the members of the Sietch have any ideas on solar tracking devices? Especially low cost.
Before we start Noah lets talk a little about maximizing your solar gain. Solar gain is the amount of sun your panel will be able to gather. You can maximize this by means of the angle and the position you mount your panel. You obviously know what I am talking about as your question is about a device to constantly maintain maximum solar gain, but for the benefit of everyone else lets talk a bit about finding the perfect angle.
