Spacing Between Solar Panels

Parallel row spacing spacing illustrations are based upon mounting solar panels measuring 1675x1001x31 using two frames secured directly to a completely flat roof 0 in two parallel rows both facing due south.

Spacing between solar panels.

For the initial baseline we start with a nominal system design featuring single module rows tilted at 15º spaced three feet apart. Our solar panels are 65 inches tall. Keep in mind that the sun travels in an arch across the sky so both the sun s altitude position and the azimuth must be accounted for when determining the length of a shadow. To define the optimization analysis for this rooftop.

A standard formula is d h tanø where d is the minimum distance between rows h is the height differential between the top of one row and the bottom of the row to the north and ø is the solar altitude angle. Module row spacing height difference tan 17 module row spacing 10 tan 17 module row spacing 32 7 rounded up to 33. Multiply the height of your solar panel by three. The inter row spacing between the trailing edge of the first row of modules and the leading edge of the next row needs to be 33.

As the temperature of the solar panel increases its output current increases while the voltage output is reduced. When designing a solar system there is often the need to understand how long a shadow will be so you can properly plan for row spacing between solar modules. The resulting number is the space that you should keep between rows of solar panels. 3 go to the area where your solar panels will sit.

We ll divide this space into 4 parts 65 4 16 25 inches and place the racks such that one rack is 16 25 inches from the top of the panel and another rack is 16 25 inches from the top of the panel. Most standard panels have a temperature coefficient of power between 0 2 c to 0 5 c. There you have it. As it happens our vertical distance on the roof is the exact length of 3 solar panels plus 1 inch of space between each row.

In many instances a solar cell can get as hot as 65 c causing the panel to become less efficient and therefore produce less power.
