Characterization of photovoltaic solar energy systems in a Colombian region

Abstract

Objective: To establish a baseline about the solar photovoltaic energy systems installed in the department of Caldas, Colombia. Methodology: The solar photovoltaic installations were identified from secondary sources of information, followed by field visits to collect information on the characteristics of these systems. An evaluation instrument was designed consisting of 6 categories which was subsequently evaluated by expert peers. It was applied accompanied by interviews with owners of the identified systems. Results: 41 solar photovoltaic systems were identified and installed in 11 municipalities of Caldas. Data was collected from 28 installations with different characteristics. 50% of the solar photovoltaic systems are in the Central-South region of Caldas. 71% of the systems are mainly installed in the urban area; 64% correspond to small-scale isolated solar photovoltaic energy generation systems, with a maximum power of less than 600W. These installations have become a viable energy alternative for the region and are being used especially for lighting and the operation of household appliances in residences, hotels, restaurants, and educational institutions. Conclusions: Although regulations on solar energy installations had not been established, these systems have already been implemented in the department in a successful, but moderate, manner.
