Photovoltaic modules can generate more electricity when receives a big quantity of solar radiation, but the efficiency of (PV) modules will drop when the temperature of solar cells is high. Therefore, reducing the high temperatures of (PV) modules will contribute to increase the electrical efficiency of (PV) modules by extraction the thermal energy associated with the PV modules and achieve an appropriate conversion efficiency of (PV). The aim of the study in this paper is to recognize the performance of hybrid (PV/T) systems in different places, conditions, module designs which can be used in household applications, hotels, etc. Aiming to supply of electricity and thermal energy. The study indicates to use of cooling technique (water or air) to cooling (PV) modules will contribute to a large extent to strengthen the work of solar cells and the efficiency of (PV/T) system as well. And the rate return of the system of electricity and thermal energy will increase, especially when the hybrid photovoltaic/ thermal (PV/T) solar systems were properly designed and the conversion rate of absorbed solar radiation for (PV) modules will increase as well.

Abstract:In this paper, the design of a system providing electricity by coupling photovoltaic/thermal (PVT) collectors and a wind turbine (WT), sanitary hot water (SHW) coming from the PVT and evacuated tube collectors (ETCs) and fresh water (FW) produced in two seawater desalting facilities (membrane distillation, MD, and reverse osmosis, RO), has been carefully analyzed by means of a dynamic model developed in TRNSYS ® . This analysis is compulsory to operate a lab-scale pilot plant that is being erected at Zaragoza, Spain. A new model-type has been included in TRNSYS ® in order to include the MD unit in the scheme. A sensitivity analysis of some free-design variables, such that the ETC surface, PVT and ETC tilt, water storage tank, batteries capacities, and mass flow rates delivered to the SHW service and/or feeding the MD unit has been performed in order to propose the definite design of the scheme. The proposed base case was able to produce up to 15,311 L per year in the MD system and cover an electric energy demand of 1890 kWh. Coverage of SHW, water (including RO and MD) and power is respectively 99.3%, 100% and 70%. However, daily and yearly assessment of FW, SHW and power produced with the optimized design gave a better coverage of water and energy demands for a typical single family home. The improved and definite design was able to increase its MD production in 35% and the electric energy in 7% compared with base case.
