Systems and methods for automating design of photovoltaic installations for placement on a selected site receive geographical information describing the site that includes areas of the site which must be spanned by support structures carrying photovoltaic panels such as canals, trenches, roads, arenas, and other features. An initial structure design which meets supplied requirements for energy production and as well as economic constraints is produced using elements produced by varying characteristics of predefined template structures. Genetic optimization of the initial design is performed to optimize dimensions of the structural elements and structural material choices to produce a structure that optimizes a fitness metric such as the levelized cost of energy.
