floating photovoltaics

An international research team has built a cooling tech consisting of heat absorber pipes that are thermally connected to the PV module, heat releaser pipes that exchange heat with the water body, a series of connecting pipes, and a coolant reservoir. The system claims to create a continuous fluid flow that dissipates heat from the PV cells to the surroundings.

A Chinese-US research group has created an up-to-date spatial datase to identify floating PV systems across the globe. The new tool uses Google Earth images, Sentinel satellite imagery, and multiple spectral indices.

A group of researchers from Belgium performed a complementarity analysis for offshore wind power combined with floating photovoltaics. The team found that complementarity is strong on weekly and monthly timescales, and that it can increase under certain climate change scenarios. Assuming a full permanent transmission loading capability, the researchers calculated that a 3 GW floating solar plant added to the existing wind power in the Belgian North Sea would increase the renewable electricity yield by 47% while occupying only a limited surface area.

Q Energy says it will deploy a 74.3 MW floating PV array in northwestern France. The project should take around 18 months to complete, with commissioning scheduled for 2025.

A Brazilian consortium is testing a new floating PV system design on a lake in the state of Sao Paulo. The facility is setting standards for future development of floating arrays in Brazil.

Teralight has completed Israel’s largest floating PV project, deploying 31 MW of capacity on two water reservoirs in the northern part of the country, at an estimated project cost of $33.8 million.

A team of researchers from Norway analyzed a case study of a cascade hydropower system hybridized with both floating and ground mounted PV under sub-Saharan African market conditions. It found that hybrid systems can reduce seasonal variability in renewable energy generation and increase annual producer profits under both PPA and spot market schemes.

A group of researchers from the US National Renewable Energy Laboratory assessed the potential for floating PV (FPV) plants at reservoirs and natural waterbodies in 10 Southeast Asian countries. It found that the overall FPV technical potential for the region ranges from 477 GW to 1,046 GW.

SJVN Green Energy has secured 90 MW of floating solar capacity in the Indian state of Madhya Pradesh with a bid of INR 3.79 ($0.046)/kWh.

Hinduja Renewables has won an 80 MW tender for the second phase of a 600 MW floating solar project, with a tariff of INR 3.89 ($0.047)/kWh.
