“…In this way (assuming θ = 0 degree) for the incident solar radiation, the part crossing the glass is τ·sw in , where τ is the transmittance of the cover system for beam and diffuse radiation, and the part absorbed by the PV cells is α·τ·sw in , with α the absorption coefficient of the cells. The data α·τ = 0.855 is very close to data found in the literature [3,5]. As stated above, we consider a constant optical parameters (a good approximation only for the central day time period).…”

A steady-state thermal model for calculate the temperature of a photovoltaic (PV) module has been developed for outdoor installation such as ground-mounted systems. The PV temperature is influenced by environmental variables such as: irradiance ambient temperature, intensity and direction of the wind, module design, orientation and mounting structure. As well as it is influenced by electrical parameters. In literature some single layer thermal balance consider only an overall heat transfer coefficient as a function of wind speed, neglecting the radiative thermal flux. In this paper, five thermal balance are compared and it is shown that the radiative term cannot be neglected, otherwise the PV temperature could be overestimated for low solar radiation intensity and it could be underestimated for high solar radiation intensity. For this reason, the percentage contribution of the heat exchanges, normalized as function of normal incoming solar radiation, are evaluated for wind speed within 1 m/s (natural convection).

At this paper is carried out the design of a photovoltaic system for a refrigeracion center. Taking into account the analysis of the consumption of energy of this installation in the year 2015 and at the first semester of the 2016 is defined the capacity of 2000MW-h / year to be instaled. To develop the work it was used the PVsyst V6.42 software, which allows to define the size of the installation keeping in mind the solar radiation that it receives in function of their location. The design of a friendly system of panels with the environment is achieved, since it is avoided the emission to the atmosphere of 38 451 tons of CO 2 in a period of 25 years and there are avoided to use 13 800 tons of petroleum. Finally is carried out an economic evaluation that demonstrates the feasibility of the proposal.Keywords: renewable energy, solr photovoltaic panels, refrigeracion center. Diseño de un sistema de paneles fotovoltaicos para um Frigorífico Diagnóstico RESUMENEn este trabajo se realiza el diseño de un sistema de paneles fotovoltaicos para un frigorífico. Partiendo del análisis del consumo de energía de esta instalación en el año 2015 y el primer semestre del 2016 se define la capacidad a instalar de 2000MW-h/año. Para desarrollar el trabajo, fue usado el software PVsyst V6.42, el cual permite dimensionar el tamaño de la instalación teniendo en cuenta la radiación solar que recibe en función de su ubicación. Se logra el diseño de un sistema de paneles amigable con el medioambiente pues se evita la emisión a la atmosfera de 38 451 toneladas de CO 2 en un período de 25 años y se dejan de utilizar 13 800 toneladas de petróleo. Finalmente se realiza una evaluación económica que demuestra la factibilidad de la propuesta.Palavras chaves: Sinalização, Trilha, Educação Ambiental. I. INTRODUCCIÓNToda la energía que se utilizará en el futuro vendrá del Sol; directamente a través de los módulos fotovoltaicos y colectores solares térmicos, o indirectamente en forma de viento y la biomasa. En este futuro sistema energético de la conversión y la utilización de energía será muy eficiente. Estos dos componentes, fuentes de energía renovable y eficiencia energética, son los componentes claves de la energía sostenible. La transición hacia un sistema energético sostenible es un importante reto social necesario para preservar la Tierra para las generaciones futuras [1].En la figura 1 se muestra la capacidad anual instalada de módulos fotovoltaicos en los últimos años.Vemos que el número de sistemas fotovoltaicos instalados entre 2000 y 2011 ha crecido casi exponencialmente, con un crecimiento medio del 60%. El crecimiento más fuerte fue entre 2007 y 2008 con un crecimiento del 143%. En estos años, con mucho, la mayoría de los sistemas fotovoltaicos fueron instalado en Europa. Sin embargo, desde 2011 el número de sistemas instalados en Europa ha estado bajando rápidamente, mientras que aumenta con fuerza en las otras regiones del mundo.Mientras que en 2011 el 74% de todos los sistemas fotovoltaicos se han instalado en Europa, en...

“…Taking this into account gives a good approximation of the electrical efficiency of a photovoltaic cell under various temperatures (ƞ e ) given that the nominal operating cell temperature (NOCT) (Dubey et al 2013). The efficiency of the cell at NOCT conditions are known from the manufacturer's datasheet and for typical crystalline Si modules β can be assumed as 0.004 (Notton et al 2005). In this respect, when the packing factor S is taken in to account, the electrical efficiency of the collector on a relative area basis ƞ elect can be expressed by equation 33.…”

The use of building integrated photovoltaic/thermal (BIPVT) concentrators is an effective way to harness solar energy within the built environment, particularly for façade applications. However, in order to precisely predict the overall performance of building integrated façade collectors it is crucial to have a validated model that represents such systems.In this study, a combined optical and thermal model was developed to describe the performance of a façade integrated BIPVT solar concentrator system and subsequently was validated with a physical prototype. Using the validated model, it was shown that key parameters such as tube spacing, and thermal conductivity between the solar cell and the absorber have a significant effect on the overall efficiency.Finally, it is suggested that façade integrated BIPVT solar concentrator systems would serve as a complement to roof mounted photovoltaic systems, and that this may be a step towards net zero energy buildings.
