Floating solar panels in the Netherlands
Floating solar panels in the Netherlands
Energy Energy Solar

Recently, Water Board Rivierenland, Blue 21 BV, Hakkers BV and TU Delft signed an agreement for the joint realization of a revolutionary way of winning solar energy on water.
Under the name INNOZOWA, the project starts. The name stands for INNOvatieve ZOn-pv (solar panels) at WAter, where we work on a flexible design, making optimal use of available space and all at a competitive price.

Water Board Rivierenland wants to innovate to connect energy goals and water management goals. Solar energy is an important renewable energy source that can replace fossil fuels. The development of solar panels does not stand still. However, the placement of solar panels on land runs against a border in the Netherlands. That while the space on the water-rich Netherlands (about 52,000ha of shallow inland water, excluding the large lakes) has enormous potential.
That is why Water Board Rivierenland takes the initiative for this project. Together with the other three parties - each with their own specialism - they work on the energy transition and water board energy-neutral 2030. Through a flexible design, using sustainable and relatively light materials, the parties develop a competitive model for the current Zon-PV systems.
With this innovation, the water board also wants to create opportunities for water management. For example, INNOZOWA is looking for ways to create added value for ecology with the floating solar panels. From autumn 2018 a pilot installation will be installed on the water storage in Weurt (Nijmegen region). With the results of this pilot, the parties expect to have sufficient data and experience to further scale up the project.
The consortium INNOZOWA consists of Waterschap Rivierenland (coordinator), Blue21 BV (a 'social enterprise' specialized in floating construction), Hakkers BV (experienced hydraulic engineering contractor) and TU Delft - Photovoltaic Materials and Devices (PVMD) research group, DC-to-AC side energy yield modeling.

Test on the Maasvlakte with floating solar panels
Testing, floating solar panels at the Maasvlakte
In the Slufter on the Maasvlakte the largest floating solar park in Europe must come. If the test is successful, more than 500,000 can be placed on rafts in the water. They can supply about 30,000 households with electricity.
In the Slufter - a full-water depot for heavily contaminated dredging sludge - are the first solar panels installed on floating rafts. Here are four builders testing their solar systems.
In one of the systems, the panels rotate with the sun. This allows them to achieve 18 percent more yield compared to stationary panels in a sunpark , says a spokesperson for the province of South Holland.
The depot has been deliberately chosen for the size of some 500 football fields on the Maasvlakte as this is proving to be one of the most sunny places in the Netherlands.

The test must demonstrate that floating solar systems are feasible in rough water. According to the county official, the construction is taken into account. An earlier test also showed that they have to be fixed properly because sometimes it blows very hard in the Slufter. The panels have deliberately not gotten an aluminum frame, but are completely made of glass, so they are not sensitive to the salt in the water.


If the pilot, involving a total of thirty government departments, companies and water boards, is successful, the Port of Rotterdam Authority and Rijkswaterstaat will investigate whether a commercial company wants to start a park of more than 500,000 floating solar panels in the depot.
The park opposite Oostvoorne could supply all inhabitants of this village, Rockanje and Brielle with electricity. The power can also be delivered to the nearby industry.
