This paper introduces a theoretical analysis of the performance of photovoltaic modules under different meteorological conditions and design parameters. Based on the analysis, A FORTRAN computer sub-program has been constructed and connected to TRNSYS simulation program. The present sub-program...

In this article, multi-reflection of radiation on both parabolic reflectors of CPC with one sided flat absorber and its effect on calculations of energy collection are theoretically investigated. Results show that, when a beam of radiation strikes on the aperture at incidence angle near zero, a...

A balcony wall type solar water heater system was designed and constructed in a high-rise building. The U-type evacuated glass tube solar collector is fixed vertically on the balcony wall. The water, heated in the solar collector, flows through the exchanger coil in the water tank and then flows...
