Solar photovoltaic (PV) systems for distributed and concentrated energy production are having at present and will have in the near future an exceptional expansion. Solar energy will possibly contribute to about 1/3 of the whole primary supply by the 2070 decade. In the present chapter we analyze the evolution of photovoltaic materials, the possibility to recycle these non-conventional power plants and the way a PV solar power plant impacts the environment. In particular, we consider: the possibility to place this type of power plants in different places of Argentina (Santa Fe province and near San Juan and Jujuy cities), the solar radiation availability in these sites and the produced annual mean electric energy. Regarding the environmental impact, we show results for the efficiencies in energy use and in reduction of greenhouse gases in the construction phase of a PV solar farm. We present general suggestions: a) Make a flux diagram of input/output and use of energy, inert materials, and contamination; b) Use the Total Quality (or other related) technique and Continuous Improvement model in the activities related to all phases of the PV solar power plant; c) At the designing stage, take into account the largest number of possible problems that will appear in the life cycle of the system and the possibility to reuse or recycle materials and the soil of the PV solar power plant that could be used, for example, as a conventional farm; d) Determine the Carbon footprint of the whole phases of the project and consider different actions for minimizing these footprints. Also, we present specific suggestions for the construction phase: a) Reduce to the minimum the change in soil quality, in order to minimize local economical impact after decommissioning; b) Build the warehouse for material storage, auxiliary elements like inverters and the habitat for the personnel that will make the maintenance of the PV solar plant, considering measures for efficient energy use, renewable energy supply and minimum emission of GHG gases, c) Make an inventory of trees that must be eliminated from the terrain and replace them by a larger number of native species in the near area.
