Recent studies on increasing the thermal-hydrodynamic efficiency of solar air collectors have been carried out installation barriers various shapes surface absorber, and this method ensures a significant increase in energy collector. The transfer flow washing absorber from laminar state to an accelerated lumped is by installing obstacles. Installation main factor heat prolongs time barrier coll...
Emerging classes of concentrator photovoltaic (CPV) modules reach efficiencies that are far greater than those of even the highest performance flat-plate PV technologies, with architectures that have the potential to provide the lowest cost of energy in locations with high direct normal irradiance (DNI). A disadvantage is their inability to effectively use diffuse sunlight, thereby constraining...
The importance of using solar energy, one the renewable energy sources, has started to be understood more recently. negative environmental effects and limited amounts fossil fuels have led increased demand for sources worldwide production various models devices accelerated take advantage which is basis all sources. Using collectors as a way benefit from been used many years. Although are genera...
Utilization of solar energy can be found in various domestic and industrial applications. The performance of any solar collector is largely affected by various parameters such as glazing, absorber plate, top covers, and heating pipes. Technology improvements have brought us another method for conversion of solar energy to direct electricity using solar photovoltaic system. Utilization and extra...
nowadays two important discussions in academic parties all over the world are energy crisis and environment crisis. one of the strategies to deal with these crisises is using clean, renewable and domestic energy sources. one of the best renewable energies that can be used in different scales is solar energy. in iran which is considered among the greatest countries that receive huge amount of so...
