In this paper, a methodology for the integral energy performance characterization (thermal, daylighting and electrical behavior) of semi-transparent photovoltaic modules (STPV) under real operation conditions is presented. An outdoor testing facility to analyze simultaneously thermal, luminous and electrical performance of the devices has been designed, constructed and validated. The system, composed of three independent measurement subsystems, has been operated in Madrid with four prototypes of a-Si STPV modules, each one corresponding to a specific degree of transparency. The extensive experimental campaign, continued for a whole year rotating the modules under test, has validated the reliability of the testing facility under varying environmental conditions. The thermal analyses show that both the solar protection and insulating properties of the laminated prototypes are lower than those achieved by a reference glazing whose characteristics are in accordance with the Spanish Technical Building Code. Daylighting analysis shows that STPV elements have an important lighting energy saving potential that could be exploited through their integration with strategies focused to reduce illuminance values in sunny conditions. Finally, the electrical tests show that the degree of transparency is not the most determining factor that affects the conversion efficiency.

Meeting the Electrical Energy Needs of a Residential Building with a Wind-Photovoltaic Hybrid System

et al. 2015

A complete hybrid system including a photovoltaic cell, a wind turbine, and battery is modeled to determine the best approach for sizing the system to meet the electrical energy needs of a residential building. In evaluating system performance, the city of Tehran is used as a case study. Matlab software is used for analyzing the data and optimizing the system for the given application. Further, the cost of the system design is investigated, and shows that the electrical cost of the hybrid system in Tehran is 0.62 US$/kWh, which is 78% less expensive than a wind turbine system and 34% less expensive than a photovoltaic system.

“…Various studies have been conducted to give the influence of ambient conditions on the performance of photovoltaic cells as in the case of [1,2,3], which determines the impact of these ambient factors on operation and efficiency of photovoltaic cells. There are many technologies available to capture and use energy from the sun.…”

ABSTRACT:The temperature of PV (Photovoltaic) modules is one of the most important factors because it affects both the efficiency of a Photovoltaic module and the energy load and it's also affected by several ambient conditions. Among these conditions, there is ambient temperature, direct irradiance and wind speed. There have been many studies that determine the effect of these parameters on the efficiency and performance of PV cells; but there is no particular study that has discussed the influence of these parameters on the thermal parameters of PV cells. This paper evaluates the effects of ambient conditions on the Photovoltaic module's thermal characteristics of two photovoltaic modules: crystalline and amorphous silicon technologies. The results show that the ambient conditions affect the PV module temperature and also the thermal parameters. The influence of these factors should be taken into account so as to have a deep insight in solar cell design.
