Financial analysis of photovoltaic configurations for Colombian households

In this paper we analyze the financial feasibility of different solar configurations as alternatives of microgeneration at Colombian homes. We designed five solar solution configurations considering the connection availability to national grid, batteries as a storage option, and the possibility to sell the surplus to the national electricity system. Then we developed a financial model to determine microgeneration cost of each configuration and we compared those costs with the electricity tariff offered by local electricity companies. We found that all the configurations (ie, with or without batteries and grid connection) represent saving money for residential users along several cities, which sets the solar technology as a real solution for electricity micro generation in Colombia.
