People were talking about what angle to set the tilt of the solar panel for different cities around the world. All of the suggestions were about using charts, books or internet sites to get the information. Yes, the sun moves and the tracker takes care of East to West settings; my simple solution takes care of North to South settings without the math or internet. You can reuse this dowel method to adjust the tilt of the panel manually just a few times a year as seasons change and the sun is at a different angle in the sky. It will be close to accurate and will avoid having to adjust the panel as often.
There is an easy way ati adjust your solar panel whether level or not level, any season, any sunny day, anywhere on earth, any time of day, NO MATH involved. In the center of a piece of plywood or plastic, mount a 1inch x 12 inch dowel. Place the piece on the solar panel so that the dowel is in the exact center of the array, and temporarily tape it in place. Adjust the panel until the dowel has no shadow whatsoever around it, and your solar panel is now facing head on into the sun. Remove the plywood and you will be getting the maximum output. No Calculations needed!
There is an easy way to adjust your solar panel for tracking on level or unlevel ground, any season, any sunny day, anywhere on earth, any time of day, NO Math involved. Cut a piece of plywood or plastic, mount a 1 inch x 12 inch dowel in the center. Place the plywood with dowel installed in the center face of the solar panel and tape it there temporarily. Adjust the placement of the plywood so that the dowel has no shadow at all. When there is no shadow around the dowel at all, it is fully facing the sun and will give you max power. At this point, remove the plywood and your panel is facing full on into the sun. No calculations needed!
