“…The average SAT in the PV area is 0.6 • C higher compared to the control area of the case study, while the average water temperature is 1.5 • C lower compared to the control area. The results in our case study are consistent with those of Li et al [19]. They monitored air temperature and water temperature simultaneously and showed that the average air temperature at the PV site is 0.16 • C higher compared to that outside the PV site, and the water temperature is almost lower compared to that outside the PV site.…”

“…The coverage of PV power decreases the shortwave radiation within the PV area, which is conducive to a decrease in water and air temperature [20]. On the other hand, it should be noted that the PV panels emit long-wave radiation, thereby contributing to the heating of the surrounding atmosphere [19,21]. The average net shortwave radiation in the PV area (26 W/m 2 ) decreased by 96% compared with that in the control area (717 W/m 2 ) of the case study, while the net longwave radiation increased from −102 W/m 2 in the control area to 44 W/m 2 .…”

To date, most studies focus on the ecological and environmental effects of land-based photovoltaic (PV) power plants, while there is a dearth of studies examining the impacts of water-based PV power plants. The effects of a fishery complementary PV power plant, a kind of water-based PV technology, on the near-surface meteorology and aquaculture water environment were investigated in coastal aquaculture ponds in southeast China. The results showed that PV prevented 89~93% of the solar radiation on the surface of the pond, resulting in an average reduction in water temperature of 1.5 °C and a substantial decrease in light intensity of 94%. Furthermore, it weakened the wind speed by 41~50% and elevated the surface air temperature by an average of 0.6 °C. In addition, PV power results in an impressive decrease in chlorophyll-α of 72~94% and a notable increase in dissolved oxygen (DO) concentrations of 8~24%. PV power also reduced the concentration of labile phosphate, active silicate, total nitrogen, total phosphorus, and total organic carbon. However, the PV power did not have a substantial influence on the concentrations of nitrate and ammonium. Our results highlight that fishery complementary PV power plants may be able to improve water quality and benefit shade-loving species.

“…The daily variation of USR for the FPV site is greater than the REF site because the albedo (albedo = USR/DSR) was increased (the FPV site albedo was 6.56%, the REF site albedo was 6.63%) on sunny day. But Li et al found that the albedo is decreased after deploying the PV arrays on lake 20 . Because the albedo of lake is higher than the PV panel materials.…”

The underlying surface was the important media of air-lake interaction by transferring energy. The deployment of photovoltaic arrays on the lake has formed a new underlying surface type. But the new underlying surface is different from the natural lake. The impact of fishery complementary photovoltaic (FPV) power plants on the radiation, energy flux, and driving force is unclear. Therefore, the analysis of radiation, energy flux, and driving force by comparing the difference in the two sites under various synoptic conditions. The results indicated that the radiation components are not significantly different in the two sites under diverse synoptic conditions. The downward shortwave radiation (DSR) and net radiation ($${R}_{n}$$ R n ) were presented with one peak on a sunny day. The daily average DSR and Rn in the two sites were 279.1 W·m−2, 209.3 W·m−2, respectively. The daily average (cloudy day and rainy day) sensible heat flux in the two sites was 39.5 W·m−2 (FPV site), 19.2 W·m−2 (REF site), respectively. The latent heat flux was 53.2 W·m−2 and 75.2 W·m−2 on counterpart. The water body generally absorbs heat from the air (daily average ∆Q was 16.6 W·m−2) in the FPV site on a sunny day. The driving force of sensible heat flux in the FPV site was governed by the temperature of the FPV panel under sunny and cloudy conditions. The latent heat flux was determined by the product between wind speed and water-atmosphere temperature difference.

Solar energy is among the sustainable and renewable energy sources that have become an important and inevitable part of our lives today. It is of great importance to consider economic, environmental and social factors in determining the installation locations of solar power plants (SPP). In this study, it is aimed to determine suitable areas where SPP can be established in Safranbolu district by using the Fuzzy Analytical Hierarchy Process (FAHP), which is one of the Multiple Criteria Decision Making (MCDM) methods together with Geographic Information Systems (GIS), in order to enable the decision makers to express their preferences in approximate or adaptable ways. The criteria addressed in the technical analysis process were also determined by supporting the basic principles of impact assessment systems. Within the scope of the environmental analysis, the relevant national and international legal framework was also examined and the legal constraints were identi ed. Thus, in the process of determining the optimal areas for SPP, it has been tried to produce sustainable solutions that are expected to have minimal impact on the integrity of the natural system. According to the results obtained, there are very suitable areas for SPP installation in the central and western parts of Safranbolu district, and there are also areas suitable for SPP installation in the northern and southern parts of the district. It was also observed that these areas do not con ict with the basic principles of impact assessment systems.
