The Dutch company Wattlab, specializing in marine solar energy, has completed the installation of 44 Flatrack solar panels on the cargo ship MV Vertom Tula, operated by the international company Vertom. The 79 kWp system is expected to reduce the vessel's energy consumption by approximately 20%, according to company estimates.
The installation, completed in a single day at the port of Harlingen, was the result of three years of pilot testing between the companies. The panels were produced and assembled at Wattlab's new factory in Rotterdam, and utilize a quick-fit system that facilitates assembly and storage.
Transition in maritime transport
The system was designed to withstand the harsh conditions of coastal shipping, offering energy efficiency without interfering with loading and unloading operations. Partially funded by the European Union's Just Transition Fund, the project aligns with policies to decarbonize the maritime sector in the face of regulatory pressure and the volatility of fossil fuels.
The technology was also validated by the independent organization TNO, which confirmed the emission reductions and the financial payback time. The innovation earned Wattlab nominations for the IBJ Environmental Protection Award and Bulk Carrier of the Year award, in partnership with Vertom. The system will be officially presented during the Europort trade fair in Rotterdam.
With over 100 vessels in operation, Vertom aims to expand the use of solar solutions across its fleet. Wattlab believes this model can accelerate the energy transition in maritime transport, offering efficiency, cost savings, and a reduced environmental impact without compromising cargo capacity.
