Conclusions
Due to the existing institutional policies in the country, it can be inferred that in light of the investment deficit by public entities regarding renewable energies and incentives to promote its use, there is a shortage in the execution of photovoltaic projects in the SIN. It is identified that 70% of the projects executed at the macro and micro level are owned by private entities mostly located in the Atlantic, where high radiation is present. In like manner, it is evident that the projects executed by public entities do not present a process of maintenance or monitoring over time, which affects the sustainability of these facilities. Photovoltaic development in Colombia is of 5.28 MW installed between Non-Interconnected Zones and zones belonging to the National Interconnected System, with a greater development in the Bogotá Capital District (Bogotá D.C.), considering that it is a zone of low solar radiation, but of high economic capacity. There is a low development of solar infrastructure in the educational facilities, although they should be an example of both formative and photovoltaic execution in the axis of a sustainable society. Colombia is mostly a desert region with high levels of solar radiation, this characteristic and what has been presented above confirms the deficit of photovoltaic development in the ZNI that waste the solar resource and the great territorial extension. A deficit is identified in the three elements that allow photovoltaic development in a country: politics being the first, seen from the legal framework, elimination of barriers, proposals, and incentives, among others. The research as second, seen from the efficiency energy, saving and technological development. Finally the monitoring, which allows, to maintain in real time how much project evaluating the achievements based on error and success.
