Water Quality Remains Stable under Floating Photovoltaic Systems
The German renewable energy company Bayware published preliminary findings on the environmental impact of the 27.4MW "Bomhofsplas" floating photovoltaic power plant located on a quarry in the Netherlands, which is currently the largest floating photovoltaic project outside China.
This research with the help of its Dutch subsidiary Groenleven, Hanze University of Applied Sciences, Groningen University, and research institute Buro Bakker/ATKB, has been investigating the environmental impact of the plant for more than a year. Toni Weigl from Bayware said: "The initial results of the environmental research did not show any significant negative impact on the lake's flora and fauna." On the contrary, the first result is positive. The erosion on both sides of the lake has decreased, and we are very happy seeing that our floating solar system is well integrated around the lake."
The research explained that the oxygen content in the water under the photovoltaic module changes little within a year. Wind and sunlight still easily reach the water surface under the module, and the measured deviation is mainly caused by changes in weather conditions. According to Hanze University, the water quality under this system is at the same level as the adjacent water surface.
Also, they found that these components reduce wind on the water surface, thereby reducing riverbank erosion. Allegedly, this is to protect the local vegetation and stimulate the growth of plants.
The impact on fish populations is still under investigation. In order to strengthen the underwater ecosystem and promote biodiversity, Bajwa reinstalled protective cages under the floating components filled with shells, the so-called "biological huts." To obtain a complete result, several years of investigation must be conducted.
Bayware stated that it hopes to continue to promote floating photovoltaic power generation while paying attention to biodiversity and water quality. The company is currently building another power station in Uivermeertjes. After completion, its output power should be 29.8 MW, so it is even larger than the leader "Bomhofsplas".
