However, the available open-source packages apply excessive simplifications to the model of light-matter interaction, making that the optical behaviour of the systems can not be properly characterized, which in turn implies disagreements between physical experiments and computer simulations.
SOLTRACE EXAMPE SOFTWARE
Eng.Ray tracing software systems are commonly used to analyze the optics of solar energy devices, since they allow to predict the energy gains of devices in real conditions, and also to compare them with other systems constantly emerging in the market. 92(6), 507–520 (2016)Ĭagin, S., Fischer, X., Delacourt, E., Bourabaa, N., Morin, C., Coutellier, D., Carré, B., Loumé, S.: Specialized reduced models of dynamic flows in 2-stroke engines. 18, 509 (2007)Ĭagin, S., Fischer, X., Delacourt, E., Bourabaa, N., Morin, C., Coutellier, D., Carré, B., Loumé, S.: A new reduced model of scavenging to optimize cylinder design.

Besides, it should be noted that, for certain conditions, power collected at the bottom part of the receiver is greater than the upper part. The results show that triangular reflector is a promising reflector because, with great simplicity of construction, allows higher powers than parabolic reflector, for certain times of the year.
Finally, computationally results are compared with experimental results with respect to efficiencies and power collected and generated by solar panel, for a particular day of the year and for an aluminium reflector with a certain tilt and aperture. This Software allows to conclude about in which conditions it is collected the highest power in the receiver and do a comparison with another type of concentrator the parabolic concentrator where we try to understand in which months and tilts the two reflectors are more beneficial in terms of power collected by the panel. (SolTrace, National Renewable Energy Laboratory (NREL), Golden, 2012). Most of the analysis is made using a Software intended to simulate solar rays trajectory: Wendelin et al. Then, a different type of concentrator is studied: triangular concentrator. In this work, firstly, it is intended to make a study of photovoltaic cells, analyzing the behavior for different environ- mental factors that affect its operation: irradiance, temperature and shading. These devices are used to reflect and focus solar radiation in the desired location, normally on photovoltaic cells, bringing enormous benefits because the latter continue to have a huge cost in the panels and concentrators allow a reduction in the number of cells. Over recent years, much attention has been focused on an emerging solar technology: solar concentrators. Solar Energy can be used in various ways: there are solar collectors to heat water and air, photovoltaic panels that produce electricity and PVT collectors (Photovoltaic Thermal Collectors), which are basically a hybrid solution.
