It didn’t take much over an hour and cost maybe $5 to make, plus about $15 for grids. It would be neat if some enterprising person were to calculate the grids and print them! I built mine after she had quit business, but still had grids to sell. There were no moving parts, and all the data you wanted in a single view. You could pick any month line, and following it, see at what time the sun “rose” and “set” in that month and what was causing the shading. Solar exposure for your position was viewed as a single image. It always appeared at the correct time and date on the grids. The sun was safely dimmed by the fish eye viewer. You could hand hold the device as you could see the compass and bubble level thru the viewer, or tripod mount. These grids were sold calibrated for every 2 degrees of latitude you ordered for your area. There were “vertical” lines for noon and the full day in hours. There were lines showing the solar path for each month. On that plastic is printed the path of the sun as viewed through the door viewer. A thin sheet of clear plastic wraps around the half circumference, standing up vertically for 6-12″. You put a round bubble level and a compass to orient the board. It was invented by a woman in California at least 30 years ago.Īt the center of a plywood 5″ radius half circle, you put one of those super wide angle door security viewers. There is a much easier way to do this job. Posted in Solar Hacks Tagged shade finder, solar, survey Post navigation Stick around after the jump to see a short video of the shade finder in action. We have to say that we’re extremely impressed by his shade finder – hopefully his work can help others maximize the efficiency of their solar solutions. The science behind the tool is best explained by, so be sure to check out his site for plenty of details and diagrams. In short, his shade finder tool uses a pulley, a pair of rollerblade wheels, and a pencil to accomplish a full shade survey in under a minute. While taking measurements recently, he started thinking about how he could improve the process, and came up with a stellar solution that reduces the process down to a one-minute task. The process requires to take elevation and Azimuth measurements of many different points, which often consumes about half an hour of his time. One process he carries out whenever building a solar installation is creating a sun chart to determine how much (or little) sun the target area will get. Does a lot of tinkering with solar-powered applications, a hobby which can be very time consuming if done right. ![]()
