The HydroSolar project, co-financed by the European Fund for Regional Development, the Italian State, and the Autonomous Province of Trento, has the aim of designing and constructing a new concept in photovoltaic systems that can be installed on fresh and saltwater basins to produce energy in a more efficient and environmentally friendly way. A floating system is superior to traditional photovoltaic systems on land and does not occupy valuable space that could be used for agriculture, manufacturing, and residential use.

The technology is based on an innovative floating platform that is resistant to atmospheric conditions, specifically wind and waves. The bell-shaped alignment of the photovoltaic modules in an east-west facing direction avoids the issue of shading between the rows of the modules and creates less wind resistance, increasing the stability and reliability of the system.

The single-span solution, with photovoltaic modules facing south, is resistant to atmospheric conditions and offers higher performance. One of these technical solutions will be suitable, depending on the location and environmental conditions of each individual project.

The results to be expected from this photovoltaic system are:

    • an increase in energy production compared to traditional ground photovoltaic systems, thanks to a range of factors including a microclimate that leads to less overheating of the modules and conductors, and modules that match the albedo of the water. These factors result in up to 15% more energy being produced than in a traditional land-based system.
    • a reduction in the proliferation of algae, thanks to water being shaded by the system.
    • a reduction in water evaporation from the reservoir, conserving the increasingly precious water resource.
