Distance between solar panels to avoid shading.

The following formula gives you the distance from the trailing edge of one row to the trailing edge of the subsequent row or your row width. To avoid any shading for reading lat 51 5 you should take alpha as 15 degrees or in simple terms 3 73 times the height of the panels between the top and bottom of the panel between the back edge of the panel and front edge of the next panel. How to calculate spacing between two solar panels. In order to avoid shading losses.

Row width minimum module row spacing cos tilt angle x module width. Row width 24 cos 15 x 39 41. Roll it down to the bottom of the panel and record the measurement indicated. The further north you go the lower the angle gets.

For example if you are designing an array for a flat commercial rooftop and there is a 4 ft tall hvac unit on the roof you need to know where to position the solar modules to avoid the shade. Multiply the height of your solar panel by three. Row width 62. The resulting number is the space that you.

Find me on. Its actually correct for avoidance of shading between 10 and 2 on the winter solstice when the sun is at its lowest inclination of the year. Place a measuring tape end at the top of one of the solar panels. This is significant because every cell in the cell string has to operate at the current set by the shaded cell.

You have to measure the incline angle and then you can estimate the distance briefly. Due to shading on solar cells the solar panel efficiancy drops down very rapidly. This prevents the unshaded cells from operating at maximum power. Sure you may get minimimal shading in early morning and late afternoon when the panels arn t really producing much but the op asked for the minimum allowed and that is the formula for it.

How to prevent solar panels from shading one another. A shaded solar cell is similar to a clog in a water pipe.
