This investigation evaluated the performance of a photovoltaic (PV) panel system under varied cooling speeds of a calibrated wind generator. The objectives encompassed the calibration of wind speed, integration of the wind generator with the PV panel system, monitoring the performance of the PV panel with wind-induced cooling, and analyzing overall performance under different wind generator settings. Parameters assessed included open circuit voltage, short circuit current, PV panel surface temperature, and power output. The tests were carried out both with and without wind cooling and under artificial and natural lighting conditions. Under artificial lighting conditions, the solar PV panel demonstrated suboptimal short circuit current compared to natural lighting conditions, leading to an overall decrease in power output. Moreover, the findings revealed a significant relationship between simulated wind speed and the overall performance of the PV panel, with notable variations in surface temperature, voltage level, current level, and power output. The statistical analysis supported these findings, with all dependent variables exhibiting statistically significant differences. The practical implications of these observations are pertinent to the design of more efficient and sustainable PV and PV-wind cooling systems. By comprehending the influence of wind on PV panel performance, system designers and operators can make informed decisions to maximize energy production and enhance the overall efficiency of the PV system.

Solar energy offers several environmental, economic, and energy security advantages. Parasitic parameters and shading on solar panels can reduce efficiency. This paper presents a bio-inspired Enhanced Slime Mold (ESM) algorithm search strategy to find the optimal power point by simulating the behaviour of slime molds in a virtual environment. In a solar panel, proposed ESM provides not only for parameter extraction but also serves as Maximum Power Point Tracking (MPPT) during Partial Shading Conditions (PSC). Proposed ESM dynamic behaviour is examined under solar irradiation and various temperature conditions. The effectiveness of proposed technique has been validated by extracting parameters from conventional polycrystalline and monocrystalline modules in the form of a 5S-5P arrangement. In the instance of MPPT operation, the proposed ESM algorithm is compared with Ant Bee Colony and Perturb& Observe (ABC-PO) to determine its efficacy. Moreover, during extraction of unknown parameters of solar cell ESM is compared with existing optimization algorithms such as Artificial Bee Swarm Optimization (ABC SO), Genetic Algorithm (GA), Covariant Matrix (CM), Ant Bee Colony (ABC), and Advanced Particle Swarm Optimization (APSO). In this connection, proposed ESM algorithm is superior to above-mentioned algorithms due to high accuracy, a smaller number of computations, and minimum computational time.

The large consumption of nonrenewable energy has caused energy shortages and environmental climate problems, and improper food storage has caused a large amount of food waste. To solve the problem of energy shortage and waste in grain transportation, a photovoltaic direct-drive refrigeration compartment based on apple transportation is designed. The design adopts a 15-foot refrigeration compartment and uses lightweight crystalline silicon PV modules to reduce the overall weight of the refrigeration compartment. According to the room size, eight parallel PV modules are selected for power generation. In conjunction with the PV modules, the rated power of the chosen compressor is 2.6 kW. Based on the storage conditions of apples, the design storage temperature is 0 °C, and HM-EO-2 is used as the refrigerant for cold storage. According to the transportation requirements of apples, the designed cold storage capacity of the cryogen should meet the 48h cold load. The mathematical models of the cold load of refrigeration compartments, refrigerant storage, and solar irradiation are established, which verify that the refrigeration system is correctly selected, and the critical parameters of the cold storage system are designed. It is calculated that the maximum hourly cold load and the daily total cold load of the refrigeration compartment are taken on June 29. The maximum hourly load is 1.355 kW, and the daily total load is 16.781 kW. The selected compressor can meet the real cooling demand.
