Solar Panels Hybrids

Solar Panels Hybrids

From the principles of humanity, man has been part essential in the process of power generation, is of a type that is, there has been a crucial point which has done innumerable studies, should also be referring to performance obtained in the process of conversion of this energy. There are many types of energy conversion processes and each of them is limited by a number of causes, whether mechanical, electrical, environmental, etc, which makes the retrieved performance not optimal enough. In the case of solar energy, specifically in the conversion processes of solar photovoltaics through a solar panel and other existing methods, one of the greatest determinants of such final performance is, among others, the effect of temperature on the photovoltaic panel and the cells that compose it. By the very nature of photovoltaic cells, produced by radiation, temperature increase causes an increase in generated power, but at the same time there is a decrease much greater than the tension around the 2mV per degree Celsius of temperature increase, i.e. a drop in performance between 0.04% and 0.06% per degree Celsius. The overall effect is that the power of the panel decreases by increasing the working temperature of the same. A 1,000 W/m2 radiation is capable of heating a panel about 30 degrees higher than the temperature of the surrounding air, which reduces stress on 2 mV /(celula/grado) 36 cells 30 degrees = 2.16 volts and therefore the power by 15%. It is therefore important to lay the panels in a place in which they are well-ventilated, since the temperature reaching the cells is always higher than the ambient temperature. This situation, which in principle is presented as a problem, served as a starting point for the creation of hybrid solar panels, which dually exploit the Sun’s energy to produce electricity and heat. These solar panels are composed of two superimposed parts; at the top we would have a panel photovoltaic traditional that it will generate an electrical current proportional to the solar irradiation, and below this, clinches a coil that makes the times of absorber of heat, which circulates a liquid inside her calo carrier that picks up the thermal energy produced in the coil and it gives it through a heat exchanger to a solar tank.
