Resumen:

SolCoSi (SOLar COllector Simulator) is a software program developed in order to determine the thermal performance of flat plate solar collectors used in solar water heating systems. SolCoSi can be used as a tool for design and optimize flat plate solar collectors, it enables an analysis of different materials and dimensions of the absorber, transparent covers, number of tubes, types and dimensions of insulation, selective surface, and different working conditions (mass flow rate, wind speed, solar radiation, etc.). The mathematic model consist in a two-dimensional arrange of nodes disposed in longitudinal and axial direction; in order to determine the temperature in each node, an energy balance was solved. As a result, SolCoSi predicts the thermal efficiency curves (lineal or quadratic), the incident angle modifier factor, the stagnation temperature (calculated for the particular case when the mass flow rate is near zero) and the temperature distribution in fluids and solids. The model developed is available as free online software in English and Spanish on the following website: http://solcosi.ier.unam.mx/. © 2017. The Authors.
