Ground-Mounted Solar Panels


A popular installation approach is ground-mounted solar panels. In situations where you have some ground area to work with (free of shade), and when you want the array off your roof, consider a ground mounted solar option.

About 30% of our solar installations for farms and homes are ground-mounted. Eternal Renewables has installed some of the largest residential ground-mounted solar arrays in Tamilnadu for homes with large electric bills.

Ground-mounted solar considerations are economical installations and eliminate the need for rooftop work. Open frame structures allow greater ventilation of the panels, improving electrical efficiency of the solar array since solar cell efficiency drops under hot summer temperatures.

Array Configuration

Our typical ground mount solar installation features are available in 3, 4 or 5 panels per column layout. Most installations today are 5 panels per column since that yields the lowest installed cost.

We also offer ground mount racking solutions that arrange the panels vertically, or in “portrait view”. These racks feature 2 panels per row and typically offer racks in 2×5 up to 2×9 configurations.

Rack Construction

A popular solar ground mount option is an engineered 2” galvanized steel pipe rack secured to the earth via concrete foundations. After the pipe frame is constructed, rails are fastened to the frame, then end and mid clamps secure the solar panels to the frame. A typical construction sequence is shown in the photos.

Tilt Angle

The typical ground mount array tilt angle is 25 to 35 degrees and lower tilt angles are possible. For smaller farm and residential ground mounted arrays, a fixed axis is most common and cost effective.
