Also, be sure to note the month and time of day. To calculate the sun's angle, divide the length of the stick by the length of the shadow. Next, find the inverse tangent of that value - use tan^-1 for the inverse tangent. If using a scientific calculator, be sure that it is set to degrees and not radians. Repeating the above experiment multiple times a day, over a course of time, eventually yields a table of sun angle values.
Solar panels need the maximum amount of sunlight to produce the maximum amount of solar power. They need to be pointed in the direction that captures the most amount of sunlight. Learning how to figure the correct angle for solar panels can help you get the most efficiency out of your panels.ere's how to calculate the best angle for your solar panels: 1  The quick and easy (but less effective) way: take your latitude and add 15 degrees for the winter, or subtract 15 degrees for the summer.
