Photovoltaic, a protective roof and production tool in Vietnam
Fraunhofer, the German international development organisation GIZ and the Vietnamese seafood supplier Viet Uc Seafood are working on a project for shrimp breeding pools covered with solar panels. Land-based aquaculture operations, which are common in Vietnam, usually cover their water tanks with a solar panel cover.
to protect them against diseases transmitted by birds trying to fish or whose droppings could pollute the water.
The addition of roof panels provides more shade and slightly reduces temperatures below the canopy. This not only increases the growth rate of shrimp, but also reduces water use. Such a reduction in the consumption of water from the Mekong River would bring enormous benefits to the population.
According to its initial analyses, Fraunhofer ISE estimates that a 1 MW project installed in Bac Lieu would reduce CO2 emissions by around 15,000 tonnes per year and water consumption by 75% per year compared to a traditional shrimp farm.
A second project is studying the installation of 400 kW solar roofs over a pangasius-shark catfish farm. The idea is still to use twice the space on land: on the ground, the fish, on the top, the solar panels. The study will last three years to analyse the performance and effects on smaller sites before two large installations are built.
In a third stageFraunhofer will seek to develop small and medium-sized fish farms in order to improve the lives of farmers.

Editor's note Photovoltaics is accepted if it is integrated into everyday life and does not disturb it. If it offers a physical advantage for swimming pools (cover) and a financial advantage, there is no reason for it to be rejected. On the contrary! It is therefore the installation on the roofs that will make it possible to overcome the resistance of the populations.
