The invention is a method for constructing solar energy mounting apparatuses in which structural elements of the apparatus are cast in molds formed on a substantially horizontal surface. A self curing compound, such as reinforced concrete, is used as the material for the structural elements. After curing for sufficient time to achieve strength necessary to allow for handling, the structural element is hoisted into place in a substantially non-horizontal position. Alternatively, the structural element may be used in the moving portion of a solar energy mounting apparatus that performs a tracking function. The use of reinforced concrete in the structural elements of solar energy mounting apparatuses allows for cost reduction over the prior art in that reinforced concrete is less expensive on a unit strength basis than other typical structural materials, such as steel and aluminum. Additional cost reduction is possible because the mass of the reinforced concrete structural elements offsets ballast material that would otherwise be necessary to increase the mass of the foundation to provide resistance to overturning forces due to wind.
