Distance Between Solar Panels To Avoid Shading

How to prevent solar panels from shading one another.

Distance between solar panels to avoid shading.

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. This is significant because every cell in the cell string has to operate at the current set by the shaded cell. This prevents the unshaded cells from operating at maximum power. 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.

Row width minimum module row spacing cos tilt angle x module 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. Roll it down to the bottom of the panel and record the measurement indicated. The resulting number is the space that you.

Due to shading on solar cells the solar panel efficiancy drops down very rapidly. Type 2 or more characters for results. When designing a solar system this is often used during the layout process. In order to avoid shading losses.

Row width 62. How to calculate spacing between two solar panels. The way in which we can prevent such power losses due to shadow is shown in the next part of the video. The further north you go the lower the angle gets.

Place a measuring tape end at the top of one of the solar panels. Row width 24 cos 15 x 39 41. Multiply the height of your solar panel by three. 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.

You have to measure the incline angle and then you can estimate the distance briefly. 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.
