“…The average temperature of PV module along with the cooling system can be 44.8 • C, while the average temperature of PV without a cooling system seems to be 50.9 For every 100 W/m 2 increase in solar radiation the electrical power and electrical efficiency increase about 19.65 W and 0.06%, respectively. For every 10 L/h increment of fluid flow rate, the electrical efficiency increases about 0.43% [44] 2018…”

“…There are currently several types of cooling systems for PV modules, classified according to the author and level of development of the technologies [41][42][43], but they are mainly distributed into two major groups: (i) closed-circuit cooling system, in which the fluid circulates in a thermal collector, exchanging heat with the PV module, that is, in a confined environment [44][45][46]; and (ii) open-circuit cooling system, in which the fluid is directed at the PV module, running through its area in an unconfined manner, without the aid of pipes, ducts, chambers, etc., that is, in direct contact com with the environment [47][48][49][50][51][52][53].…”

This work aims at analyzing and architecting natural and artificial parameters to model a water-film cooling system for photovoltaic modules for some months under warm conditions. Methodologically, the theoretical and technical aspects were structured to develop, implement, monitor, and assess the cooling system at an on-grid, outdoor testing unit, considering the following: (i) the criteria to select and to approve the implementation site (infrastructure and climatologic and solarimetric conditions); (ii) the types, frequency and qualities of the monitored data; (iii) the system measurement, monitoring and control equipment; (iv) the commissioning of the system as a whole; and (v) the tests and results empirically obtained. The water-film cooling system reduces the temperature by 15–19%, on average, and up to a maximum of 24–35%. In terms of electric power, there was an average gain of 5–9% at the time of day with the highest solar radiation, and maximum gains of 12% on days with solar radiation above average. Regarding gross energy, average gains of 2.3–6%, and maximum gains of 6.3–12%, were obtained. It was concluded that the test unit helps understand the natural phenomena and the development, operation, and maintenance of performance gain systems of on-grid PV modules for construction on a commercial scale.

The Influence of Weather Conditions on the Optimal Setting of Photovoltaic Thermal Hybrid Solar Collectors—A Case Study

et al. 2020

The potential absorption of solar energy in photovoltaic thermal (PVT) hybrid solar collectors at different tilt angles was compared in the present study. The optimal tilt angles were tested in three variants: during 1 day, 1 year and a period of 30 years. Simulations were performed based on actual weather data for 30 years, including average hourly total radiation, insolation and air temperature. The apparent movement of the Sun across the sky, solar radiation properties, and the electrical and thermal efficiency of a PVT collector were also taken into account in the simulation model. The optimal orientation of the absorber surface was determined by solving an optimization task. The results of the study indicate that in the long-term perspective, the collector’s performance is maximized when the absorber is positioned toward the south at an elevation angle of 34.1°.

The reason for utilizing PV-T systems is their capability to generate both electricity and heat at the same time, which enhances energy efficiency and decreases the need for multiple energy sources. Considering the potential of solar energy and different climates in Iran, in this research, the feasibility, modeling, and comparison of the PV-T system to supply electricity and heat to residential units were investigated in 28 cities with 9 climates of Iran. A thorough evaluation of performance was conducted using the software Polysun 9.0 and PVsyst 6.6.8 for a duration of one year. The scientific novelty of this study relies on the simultaneous utilization of two analytical software, the thoroughness of the research, and taking into account the impact of climate on the findings. Investigations showed that the best performance of the designed system is related to Bandar Abbas and Zahedan, and the worst performance is related to Rasht and Sari. In general, according to the amount of electricity and heating produced by the PV-T system, it showed that Shiraz and Rasht stations have the highest and lowest production of energy. In terms of environmental effects, Birjand station will have the most and Rasht the least reduction in CO2 emissions. In terms of heating energy demand for the investigated building, Ardabil has the highest amount and Bandar Abbas has the lowest amount.
