So, presumably ignored for days on end, but plenty of opportunity to site it perfectly in the first place. This lets you face it dead South, (include a place to install a compass far from metal if you can, pre-adjusted for local deviation), and set the angle of the panels for maximum output. Tracking would seem to involve too much work (either manual over the day, or in additional infrastructure to get the panels up away from the trailer so they can swivel).
Sean Henry wrote:Sun tracking can be done fairly easily using a comparator circuit and two small solar cells from old calculators. The trick is building two small boxes one uncovered on the right the other uncovered on the left. If one is shaded it trips a relay telling it to turn to the shaded one till the voltage is equal again.
