“…The daily average total electrical and thermal efficiencies of a PV module with water flowing from the top were found to be 14.29% and 45.44%, respectively. The water flow on the top of the PV module decreased the average module temperature per day from 56.67 °C to 39.44 °C, and the average daily electrical efficiency of the module increased to 14.29%, compared to the 12.74% efficiency of a PV module without cooling (Senthil Kumar et al, 2019).…”

Conventional cold storage systems increase the risk of damage and are no longer used for the long-term storage of agricultural products. Thus, newer affordable and energy-efficient storage systems are required for enhancing the shelf life of farm produce. We investigated the coefficient of performance (COP) of an earthen clay pot refrigerator with a thermoelectric cooler (TEC) and explored cooling strategies to enhance cooling and electrical performance for increasing the shelf life of farm produce. We used MATLAB Simulink to analyze Peltier TEC module efficiency. The intrinsic characteristics, including the Seebeck coefficient (α), thermal conductivity (K), and electrical resistance (R), were determined, forming the basis of the Peltier module in MATLAB Simulink. Thermal characteristics such as COP and cooling capacity were studied as a function of system voltage (Vin) and current (Iin). The model was equipped with a 12 V/6 A, 60 W TEC and was verified by simulation investigation. We also used psychrometric measures (e.g., wet bulb, dry bulb, and dew point temperatures and relative humidity) to determine the extent of wetness or dryness of an object and monitor other temperatures of the clay pot refrigerator. The results revealed that the ambient temperature and cold and hot side temperatures fundamentally affected TEC performance. The TEC extended the shelf life of tomatoes, potatoes, and spinach by 60% compared to those stored under ambient conditions, thereby reducing their wastage. In conclusion, earthen refrigeration using TEC doubled the shelf life of farm produce compared to storage under ambient conditions, saving money, resources, labor, and supplies and enabling the development of efficient and environmentally friendly refrigeration systems.

The decline in fossil fuel sources has led to an increase in demand for alternative energy sources. Photovoltaic (PV) technology is one of the most promising and popular renewable energy technologies. During the realoperation of PV cells about15% of thesolarradiation istransformedintoelectricity, therestintoheat that warm up the PV cell. One of the challenges when construction a home photovoltaic capacity generation order or an off-gridiron photovoltaic capacity is the deficit of energy that is converted to heat in the cosmic photovoltaic piece, resulting in a loss of 6 volts per system at a low-energy conversion rate. However, photovoltaic solar panel systems can still offer a significant benefit by optimizing the system design by incorporating an active cooling system that would recover the 6-volt energy loss. In this research, the active cooling system of the photovoltaic module system is examined and discussed. The chill plan was installed with a leg on either side of the photovoltaic piece while the water abating arrangement was on the front. The energy and exergy analysis of both cooling systems were performed separately and combined using EES, METLAP and RET Screen Expert software. The highest temperature of the photovoltaic piece outside a cooling arrangement is 64.4℃. There is a decrease in the hotness of 21.3℃, 34.3℃and 39.4℃when the air, water and integrate chilling order is used to the photovoltaic piece plan to increase the warm adeptness of air, water and connect abating of about 8%, 14% and 23%, respectively. The system power improvement of 29.32W, 32.22W, and 37.37W for air, water, and combined cooling, respectively, was recorded.

The temperature of a photovoltaic (PV) panel has a negative effect on the generated power. As the solar irradiance that falls on the PV increases, the operating PV temperature rises, which leads to a decrease in electrical efficiency. Therefore, there arises a need to introduce a cooling system to minimize PV temperature. In this study, the simple passive cooling method of extending its surfaces with fins was used to reduce the PV temperature. Different numbers of longitudinal aluminum fins were attached to the bottom surface of a PV panel and their effects were examined under realistic weather conditions for Baghdad, Iraq. Results show that the use of the passive cooling method under natural convection will be more effective in reducing PV temperature before solar noon than after solar noon. The maximum power enhancement was about 2.5 W and occurred at solar noon when using 10 aluminum fins. The peak efficiency value of the PV panel with fin cooling was about 15.3% against 14% for the unfinned PV panel.
