“…This was attributed to the higher value of h for the case of internal cooling than that for the natural and external cooling methods. The reduction in temperature of the Si solar cell achieved in this study has been compared with the results obtained by other cooling methods reported in the 27 Farhanet al, 28 Firoozzadeh et al, 29 Hasan et al, 30 Krstic et al, 31 AI-Amri et al, 32 Ahmad et al, 33 Raina et al, 34 Hernandez-Perez et al, 35 literature and is summarized in Table 2. Apparently, the internal active cooling method proposed in this study offered a relatively higher temperature reduction in comparison to passive cooling and analogous external active cooling methods.…”

Photovoltaic power plants never realize their true production capacity during operation primarily because of the unavoidable heating of the solar modules under solar irradiation. Although the heating of silicon solar modules has received serious attention in the past decade, an effective and commercially viable solution is still unavailable. This study presents a detailed evaluation of the performance of a novel air-breathing internal microfluidic design (proposed in our patent application 202211050095 to the Government of India) that can be embedded in the photovoltaic modules to enable direct cooling of silicon solar cells. It was reported that a conventional silicon photovoltaic module had incurred a heat-induced fractional loss in the light harvesting efficiency of 21.4%, which was lowered to 11.3% when conventional external air cooling was employed. However, the proposed internal air cooling reduced the fractional loss in efficiency further down to 7.3% at the steady state.

“…Thus, inverter input is adjusted to 600-650 Volt-40 Ampere voltage and current values when the panel surface is 50℃ under sunny day conditions. The design was made considering that the efficiency of the PV panel decreases between 0.25-0.5% with each 1°C increase in temperature [21]. The 3D design and layout designs of the roof-top type PV system designed with Solarius and PV*SOL program, which can output 25 kW of power, are as in Fig.…”

The use of electrical energy from renewable energy sources has increased considerably in recent years. Photovoltaic (PV) solar energy, which is one of the renewable energy sources, takes its source from the sun, which is considered an unlimited source. With the widespread use of photovoltaic systems, some legal regulations by governments have been made for their installation. Simulation programs are used for the design, layout, technical and economic analysis of PV systems. In this study, the design was made using the PVsyst, PV*SOL, Solarius programs, and the PVGIS website used in PV systems. The projects are designed to have an output power of 25 kW. According to the simulation results, the PVGIS website provides approximate data, since technical details cannot be entered. In the results of PVGIS and all simulation programs, it has been calculated that the system can produce 42-48 MWh of electrical energy annually. Power Ratio (PR) results of the system were in the range of 78-85%. Annual electrical energy production per installed kW has been calculated to be 1436-1635 kWh/year. It is stated that the annual saved CO2 will be 18.66-22.226 tons /year. When the simulation results are analyzed monthly, the differences between the months are remarkable. The reason for these deviations can be explained by the annual solar radiation (kWh/m2) data and databases used by the programs. It has been observed that the simulation programs consider the monthly average temperatures and sunshine durations of the region. It is thought that there is a need to compare real-time data with simulation results in future studies. It is considered that this study will be helpful for future studies.
