“…They also mentioned that agrivoltaics decrease the evapotranspiration rate in crops reducing the water demand for irrigation which is important in areas with water scarcity. The advantages and the challenges of FPV have been studied [21]. The authors stated that if 1% of the surface of the world's water reservoirs will be covered by FPV the installed solar power would be increased by 404 GWp.…”

The increasing use of solar energy for heat and power generation, particular in areas with high solar irradiance like in Mediterranean region, is very important for the mitigation of climate change and the achievement of net-zero emission societies. The size of the solar photovoltaic systems which could meet all the electricity demand in Crete, Greece and the required land area for their installation have been evaluated taking into account the electricity demand in the island in 2025. Our results indicate that the nominal power of the solar photovoltaics which could meet all the power demand in 2025 in Crete is 2,333 MWp while their installation cost is 2.33 bill. € or 2,333 €/capita. The required land area for the installation of the abovementioned solar photovoltaic systems is 4,660 ha or 7.5 m2/capita which corresponds at 0.56% of the total surface of Crete. Our findings indicate that electricity self-sufficiency with zero carbon impacts in the island of Crete can be achieved with the use of the local solar energy resources while the necessary land area for the installation of the benign energy generation systems consists of only a small percentage of the island’s surface. The results could be useful to policy makers and the local authorities in the island who are interested in achieving energy security and self-sufficiency combined with carbon neutrality in power generation.

Photovoltaic cells are intricate systems that transform solar energy into electrical power. Certain internal parameters, such as diode saturation current, conversion resistance, and series resistance, significantly influence the performance of electrical components. Frequently, manufacturers do not provide these parameters. At the moment, researchers need new and clear ways to measure these factors so they can get a better idea of how solar cells work and improve efficiency through simulations. We present a novel approach to accurately determining the five parameters (series resistance, shunt resistance, photovoltaic cell current, and diode saturation current) for multi-crystalline silicon solar cell models. This approach employs the Lambert function and the curve of parasitic resistance. By utilizing the extracted internal electrical parameters, this method will enhance the efficiency of solar cells through the facilitation of more accurate simulations.

Floating solar photovoltaics (FPV) are increasingly favored for solar energy harnessing, necessitating a thorough grasp of performance-influencing factors, notably weather conditions. This study delves into the statistical scrutiny of humidity’s impact on FPV performance within tropical settings, focusing on Jakarta’s urban context. While humidity’s effect on solar cell performance, particularly voltage output, is acknowledged, its influence in urban pond settings remains underexplored. Thus, an experiment was conducted, placing a floating PV system over a 24 m2 pond to directly assess humidity’s impact. Additionally, ambient temperature and irradiance levels were analyzed to comprehensively understand their interconnected effects on system efficiency. Moreover, the study investigated airflow’s role in humidity variation and overall environmental dynamics. The experimental setup comprised two strategically positioned solar panels over a 1.5-meter-deep pond. Regression and analysis of variance (ANOVA) techniques were employed to scrutinize humidity’s impact on the FPV system. Results revealed an inverse relationship between humidity and voltage, with humidity also contributing to ambient temperature reduction, thereby enhancing the microclimate. These findings underscore the intricate interplay of factors, where humidity, driven by evaporation, negatively influences irradiance levels while indirectly benefiting PV cell temperature by lowering ambient temperature. This research provides crucial insights for optimizing FPV performance in tropical urban settings, emphasizing the importance of nuanced approaches that account for humidity’s impact on floating photovoltaic systems.
