In a ground installation a frame is built for solar panels that tilts them up to an optimal angle (usually 30 degrees) and faces the correct way as per maximum availability of solar power in seasons. The frame can be built out of galvanised steel or aluminium, and is attached to the ground via a concrete foundation. In many cases the frame will be a rigid half a frame like structure.

Where achieving the maximum possible efficiency is an aim (such as in commercial or very large installations) it is possible to have half A-frames that are manually tilt adjustable, so that in winter when the sun is lower in the sky the cells can be tilted up for greater exposure to Solar rays.
