Wattlab
Wattlab develops custom solar energy systems. With roots originating from the Vattenvall Solar Team, Wattlab builds upon their own expertise by bringing solar energy and technology to the shipping industry.
By applying thin and lightweight solar panels in the marine industry, Wattlab aims to contribute to a solution for the climate problem. The solar hatches’ energy can be used to power the onboard applications that are otherwise powered by a generator. On hybrid ships, the generated solar energy supports propulsion. The elimination of genset and fuel use results in less pollution and noise for the environment. As the usage of a generator is no longer allowed in some ports, it is required to connect to shore power, which is not always facilitated well. The use of solar hatches allows the captain more freedom as the vessel is not reliant on a fixed location with shore power.
This is a case study on how to decarbonize an inland waterway ship with solar PV technology. Flexible solar PV panels from Wattlab are placed on an inland ship’s hatches in order to reduce fuel consumption while idling or moored. In some cases, the auxiliary generators can be switched off, resulting in an expected CO2 reduction of 26% - 100%.
