“…Research has indicated that the implementation of aquatic photovoltaic systems yields a substantial carbon reduction effect, resulting in the reduction of emissions by an impressive 3.3 million tons annually [18]. It can reduce the eutrophication of water bodies and reduce the concentration of chlorophyll and nitrate in water bodies [17,40].…”

“…The rate of evaporation is influenced by temperature and inversely proportional to humidity levels, and through the adjustment of the angle of the photovoltaic (PV) tilt, it has been observed that a significant reduction in evaporation can be achieved. The implementation of single-axis tracking mechanisms or novel photosensitizers has the potential to induce varied levels of energy generation over the course of a year [17][18][19]. Despite the effectiveness of FPV, no relevant experiments have been conducted for waterborne photovoltaic (WPV), which holds practical and economic value in fishery-photovoltaic complementary fish ponds.…”

(1) Background: In arid and semi-arid reservoirs, water surface evaporation is the main method of water dissipation in order to inhibit the evaporation of water and enhance economic efficiency. The evaporation inhibition rate of water-piled PV at different times of the year is derived from the anti-evaporation test of water-piled PV, and a new idea is proposed for water conservation in plains reservoirs in arid areas. (2) Methods: The test was conducted by dividing the area into groups A and B, with and without PV panel shading. In situ observation and numerical calculation were used to measure the atmosphere’s temperatures, test group, and PV module. The saturated water vapor pressure difference was then calculated according to Dalton’s principle to analyze the economic benefits of water saving. (3) Results: Based on the test results, it was found that the shading of PV panels had a cooling effect on the water body, the PV module, and the atmosphere. Group A showed a 44.2% decrease in the saturation water vapor pressure difference compared to Group B. The maximum evaporation suppression rate of 40.2% was observed in July, while the minimum rate of 12.2% was observed in January. The average evaporation suppression rate for the entire year was 29.2%. By utilizing the annual water savings for agricultural irrigation, it is possible to cover 38 hm2 of land and generate a revenue of 39,000 CNY. (4) Conclusions: The photovoltaic water cover can effectively reduce water evaporation and generate economic benefits.

With the continuous progress of social production, it has brought huge benefits, but also led to an increasingly prominent global warming problem. Therefore, energy conservation and emission reduction has become an important direction of national industrial development. In order to promote the effective promotion of China’s carbon emission reduction action, the study adopted the improved STIRPAT model and Granger test to analyze the factors affecting China’s energy consumption carbon emissions, combined with Johan equation and GFI decomposition to decompose the factors affecting China’s energy consumption carbon emissions, excavated the key influencing conditions of China’s energy consumption carbon emissions, and put forward policy recommendations on energy consumption carbon emissions reduction. The results show that economic growth has the greatest impact on China’s per capita carbon emissions, followed by urbanization, industrial structure and energy structure. At the same time, industrial energy intensity has an inhibitory effect on per capita carbon emissions growth. From 2019 to 2021, Shanghai, Tianjin, Guangdong and other 10 provinces will achieve good emission reduction results. Therefore, in the analysis of energy conservation and emission reduction, it is of great value to understand the influencing factors of carbon emissions, which can provide direction and guidance for exploring an effective low-carbon development path, and play an important role in promoting the realization of the “double carbon” goal.

“…Such hybrid systems provide better energy security with increased generation capacity and better hydropower generation due to reduction of evaporation loss (Gonzalez et al 2021 ). Ravichandran and Panneerselvam ( 2021 ) evaluated an FSPV system of 5 MW capacities on an artificial reservoir in India. The FSPV provides annual electricity of 160 GWh and saves 1.4 million cubic meters of water by reducing evaporation losses.…”

The Floating Solar Photovoltaic System (FSPV) is emerging as a favorable technology to policymakers for economically harvesting renewable energy. The implementation of large-scale photovoltaic (PV) systems is often disrupted due to the unavailability of land. The FSPV systems, where the PV modules are floated in water bodies facilitate optimal utilization of water resources and land assets. The FSPV provides higher power output compared to land-based PV systems of the equal area because of improved energy conversion efficiency at a lower temperature. Another opportunity for the FSPV system is integration with hydropower stations, storage systems, and the electric grid. This paper explores the flood duration curve-based optimal sizing of the FSPV System with the objective of electrification of rural micro-grid. A comparison of energy output and module temperature rise has been made for the FSPV system and its equivalent land-based PV system of equal area. The system generates 18.08 GWh, which is 10.04% more than the land-based PV system. The DC Capacity factor is 17.2%. The Demand Supply Factor ( DSF ) for a particular day in winter, spring, summer, and monsoon is 37.55%, 41.7%, 45.9%, and 25% respectively. The results indicate that the FSPV system is a sustainable alternative to power renewable energy-based mini micro-grid and provide cost effective electricity to all.
