Opis:: The performance of a 15 kWp roof mounted, low angle tilted photovoltaic installation over the year 2019 has been analyzed in terms of the role of solar irradiation, ambient and module temperature, clouds cover and wind speed. The studied photovoltaic system operates under warm summer humid continental climate with the considerable influence of temperate oceanic zone. The role of significant changes of weather conditions in warm and cold part of the year has been shown. The negative impact of external temperature increase on the modules efficiency has been observed. The experimentally determined temperature coefficient of efficiency of the modules is equal to -0.06%/°C. Relatively high sum of insolation registered in the location in 2019 together with a lack of shade assure annual energy yield of 1098 kWh/kWp, energy density 188 kWh/m2, capacity factor 12.53% and performance ratio 82%.

Tytuł:: Assessment of Technogenic Loading on the Surface Water Bodies of the Separate Regions of the North-Western Black Sea

Opis:: The assessment of surface water quality and technogenic loading on the separate regions of the North-Western Black Sea, namely the Mykolaiv region, was performed in this work. The water quality assessment was conducted using the graphical method that allows determining the suitability of water for the certain types of water using, as well as the method of calculating a water pollution combinatorial index. The estimation of the technogenic loading is based on calculating a technogenic loading module. It was found that the surface waters of the Mykolaiv region do not meet the requirements of fisheries in relation to most quality indicators. According to various standards, this surface water quality in this region is characterized by the “polluted” – “very dirty” categories. A reduction of the technogenic loading by the volume of wastewater discharges since 2006 can be determined. According to the pollutant discharge indicators, a steady decrease of the level of loading has been noted since 2005, which is caused by a reduction of wastewater discharges.

Tytuł:: Assessing the Solar Power Plant Efficiency Degradation Resulting from Heating

Opis:: Renewable power sources (RPS) play an ever growing role in power production. With the green power cost decreasing, the RPS share (including hydro power plants) in power production grows fast. Using RPS in supplying power to various facilities reduces the CO₂ emission into atmosphere, thus reducing the greenhouse effect and being a fundamental factor in fighting the global warming. Every type of RPS possesses certain drawbacks that need to be eliminated. RPS units do have disadvantages, too, including low efficiency coefficient, and low specific power. However, there is the need for specific technological conditions. The present work describes the issue of photoelectric module heating. Photoelectric module heating results in both lower output voltage and module aging acceleration. The present work offers the method for assessing the practicability of development and implementation of solar power cell module active cooling systems, based on the photoelectric module daily performance schedules, drawing on statistic meteorological data collected over many years, and also it presents the brief description of various methods for cooling photoelectric modules.

Tytuł:: Experimental Study of Temperature Influence on the Performance of PV/T Cell under Jordan Climate Conditions
Autorzy:: Al-Odat, Mohammed Qassim
Powiązania:: https://bibliotekanauki.pl/articles/2202185.pdf
Data publikacji:: 2022
Wydawca:: Polskie Towarzystwo Inżynierii Ekologicznej
Tematy:: PV module

electrical efficiency
water cooling
cooling
cell temperature
Opis:: The electrical performance and the productivity of PV module depend on two main parameters, i.e. the radiation intensity and the cell operating temperature. The module electrical efficiency and productivity are significantly reduced as its temperature increases. Accordingly, cooling of PV modules is one of the most effective techniques to obtain higher efficiency and productivity as well as to reduce the degradation modes of PV modules due to high temperatures. This research work presents an experimental study carried out to investigate the effect of PV module cooling on the performance of PV module under Irbid city (Jordan) climate conditions. It was found that the electrical efficiency and the productivity of the PV modules were approximately enhanced by 14%. Therefore, water cooling of the PV modules is essential to enhance their performance.

Tytuł:: Solar Hot Water Heating and Electricity Generation Using PV/T Hybrid System

Powiązania:: https://bibliotekanauki.pl/articles/2086426.pdf

Opis:: Experimental work has been carried out to study the possibility of combining a conventional solar water collector with a hybrid device, developed previously and known as PV/T system, in order to obtain hot water with temperature above 40 °C. The effect of the combination on the productivity of hot water and the produced electricity was found. The formerly developed device, in which there was a multi-purpose solar collector, can produce hot water and electricity. It was connected to the conventional fin-tube collector in series in order to raise the product temperature to a higher level. This development was achieved for the first time as a combination between a PV/T and a conventional fin-tube collector. Instrumentation to measure temperatures, solar radiation, wind speed and flow rate was installed on the system. It was found that the water temperature was raised from 29 °C to 32 °C in the PV/T collector system and, after flowing through the conventional collector, it was raised to 50 °C and above. It was also found that the power efficiency in the case of water flow is always higher than in the case of no water flow.
