Two new designs of parabolic solar collectors

Evaluation of Surface Slope Irregularity in Linear Parabolic Solar Collectors

The paper describes amethodology, very simple in its application, for measuring surface irregularities of linear parabolic collectors. This technique was principally developed to be applied in cases where it is difficult to use cumbersome instruments and to facilitate logistic management. The instruments to be employed are a digital camera and a grating. If the reflector surface is defective, t...

Low Temperature Solar Collectors

Comparative Study of Two New Configurations of Solar Photovoltaic Thermal Collectors

Hybrid photovoltaic thermal (PV/T) solar system comprises a solar collector which is disposed on photovoltaic solar cells. The disadvantage of a conventional photovoltaic cell is that its performance decreases as the temperature increases. Indeed, part of the solar radiation is converted into electricity and is dissipated as heat, increasing the temperature of the photovoltaic cell with respect...

Roof Integrated Mini-Parabolic Solar Collectors. Comparison Between Simulation and Experimental Results

Concentrating solar collectors systems and especially the mini Parabolic solar reflecting systems have been one of the main research topics due to their ability for integration into the building structure. In the present work the mini parabolic collector was considered in the East West orientation with such a slope so that the suns vector impinging normal to the parabola during the day. The beh...
