Opis:: In this study, a theoretical model is presented to investigate the performance of a thermoelectric (TE) radiant cooling system combined with photovoltaic (PV) modules as a power supply in a building with an ambient temperature reaching more than 45◦C. The combined system TE/PV performance is studied under different solar radiation by using the hourly analysis program and photovoltaic system software. The thermal and electric characteristics of TE are theoretically investigated under various supplied voltages using the multi-paradigm programming language and numerical computing environment. Also, a theoretical analysis of heat transfer between the TE radiant cooling system and an occupied zone from the side, and the other side between the TE radiant cooling system and duct zone is presented. The maximum power consumption by TE panels and building cooling load of 130 kW is predicted for May and June. The 145 units of PV panels could provide about 50% of the power required by TE panels. The thermal and electric characteristics of TE panels results show the minimum cold surface temperature of 15◦C at a supplied voltage between 6 V and 7 V, and the maximum hot surface temperature of 62◦C at a supplied voltage of 16 V. The surface temperature difference between supplied current and supplied power increases as supplied voltage increases. At a higher supplied voltage of 16 V, the maximum surface temperature difference between supplied current, and supplied power of 150◦C, 3.2 A, and 48 W, respectively. The cooling capacity increases as supplied voltage increases, at a surface temperature difference of –10◦C and supplied voltage of 16 V, the maximum cooling capacity is founded at about 60 W. As supplied voltage decreases the coefficient of performance increases. The maximum coefficient of performance is about 5 at the surface temperature difference of –10◦C and supplied voltage of 8 V.

Opis:: The escalating prevalence of rooftop solar PVs and DC powered home appliances are the driving forces for the research in the field of DC distribution at residential level. The current research work presents comparative analyses of AC and DC distribution systems considering various scenarios for the specific purpose of efficiency/energy savings. A modern Bakersfield CA, USA home is considered for the analyses. The loads are classified according to the power demand. Rooftop solar PVs are also included in each residential building. Mathematical equations are devised for the efficiency analysis of residential buildings powered with AC as well as DC. The results reveal strong dependence of the efficiency values on the utilization/types of loads, efficiencies of the power electronic converters (PECs), solar capacity and seasonal conditions, as a function of the time of day. It is concluded that AC system presents better efficiency values as compared to the DC counterpart except during the time periods when solar power is available and when the penetration of variable speed drive (VSD) based loads is high.

Opis:: The work of solar cells and their production of electrical energy have been affected by climate change, especially in hot regions which became significantly hotter and still receive relatively high levels of solar radiation throughout the year. Higher ambient temperature and solar radiation result in higher PV cell temperature and, therefore, the reduction in PV module power output and efficiency. This study investigates how a PV module performs throughout the year in a hot region by considering the variations in cell temperature resulting from changes in ambient temperature and solar radiation every day. The tilt angles and two-axis tracking have also been examined. Results indicate that the two-axis solar tracking system is critical to use in hot regions for obtaining higher output power. Therefore, part of this power can be used to cool solar panels using various methods to keep their efficiency high, such as operating air fans or operating pumps to cool them with coolant.

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.

Opis:: Waters provide essential needs both for human societies as well as natural ecosystems. Floating solar PV (FPV) applications on water bodies are currently in strong demand worldwide. Floating solar PV system is a new concept in renewable energy with the solar plants by harnessing available water surface, such in dams, lakes, and other water bodies. Although the floating solar PV industry is becoming more and more popular, the study on the biological, chemical, and physical properties effects of using FPV cover on natural water coverage – especially in tropical countries – has not been widely carried out yet. This paper aimed to evaluate the effect of floating solar PV on temperature, DO (dissolved oxygen), TDS (total dissolved solids), total phosphorus concentration, and chlorophyll-a concentration using mesocosm experiments to understand the biological, chemical, and physical process under closed environment. The experiment was conducted in a natural water body, Mahoni Lake, in which a total amount of 7 water samples were collected from each mesocosms. The results show that the floating solar PV reduces the average temperature, DO, conductivity, TDS, and chlorophyll-a concentration changes (p-value < 0.05); and the floating solar PV does not directly reduce the average total phosphorus concentration due to high probability of thermal stratification (p-value > 0.05).

Opis:: Sunlight is converted into electricity and heat simultaneously with the help of PV thermal panels. It is examined that the efficiency of the PV/T panel is higher than the separate PV panels and solar thermal collectors’ efficiency. The electricity conversion-efficiency for a PV system is about 6% to 15% and in moreover cases 85% of the incoming solar energy is either reflected or absorbed as heat energy. Now a day’s Renewable energy has become a hot topic. The energy researchers day by day making advanced researches to make this type of system a useable one. Non-renewable sources will be approximately finished within next 100-150 years. So this type of energy is very important for everyone. Normally researches are made on producing electricity from renewable sources like sun-light, wind energy, tidal energy and etc. In this paper there is a compact review of solar photovoltaic thermal system. The performance of the solar cell decreases with the increasing of temperature. Both the electrical efficiency and the power output of PV module depend on the operating temperature. Photovoltaic thermal hybrid solar collectors, also known as hybrid PV/T systems are systems in which sunlight is converted into thermal and electrical energy both. This paper contains a combination of basic and advanced hybrid PV/T systems that are usable in Asian region.

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.

Opis:: Solar energy is widely available in nature and electricity can be easily extracted using solar PV cells. A fuel cell being reliable and environment friendly becomes a good choice for the backup so as to compensate for continuously varying solar irradiation. This paper presents simple control schemes for power management of the DC microgrid consisting of PV modules and fuel cell as energy sources and a hydrogen electrolyzer system for storing the excess power generated. The supercapacitor bank is used as a short term energy storage device for providing the energy buffer whenever sudden fluctuations occur in the input power and the load demand. A new power control strategy is developed for a hydrogen storage system. The performance of the system is assessed with and without the supercapacitor bank and the results are compared. A comparative study of the voltage regulation of the microgrid is presented with the controller of the supercapacitor bank, realized using a traditional PI controller and an intelligent fuzzy logic controller.
