Summary: Floating photovoltaic (FPV) plants offer several advantages over ground-mounted photovoltaics (PVs) and can have significant positive environmental and technical impacts globally. They can be deployed in degraded environments, reduce land-use conflicts, save water, and improve water security in arid regions. In addition, they have higher efficiency and are compatible with existing hydropower infrastructures. However, lack of government support policies and development roadmaps could hinder their sustainable growth, and long-term reliability is also a concern.

Summary: The share of hydropower in India's electrical sector has decreased over time, leading to increased greenhouse gas emissions and altered rainfall patterns. Installing floating solar photovoltaic (FSPV) plants in existing hydropower reservoirs can increase the share of hydropower and reduce evaporation losses. This study analyzes the potential of FSPV installations in Indian hydropower reservoirs and calculates CO2 and evaporation savings. The results show that by covering less than 4% of the reservoir area, existing hydropower plants can double their installed capacity and increase electricity output by 52%, generating an additional 66.56 TWh per year.

Summary: As the global population grows, the demand for food, energy, and water will increase significantly. However, limited land availability and competition for solar resources pose challenges to resource generation technologies. In the United States, both agriculture and solar energy production have adopted densification schemes to improve yields and energy output per unit of land. This research proposes an Agrivoltaic food and energy coproduction architecture that optimizes power generation while maintaining crop productivity by implementing ideal anti-tracking during critical growth periods. This technology offers a viable pathway for widespread solar implementation throughout the contiguous United States.
