Swiss Contribution

ZENNA is a photovoltaic systems consulting firm with over 10 years of experience. A solar boat will be built and tested in collaboration with experts from the Zurich University of Applied Sciences ZHAW, Wolf Shipyard (boat builder) and the Walenstadt Water and Electricity Utility (WEW). Furthermore, ZENNA will be supported locally by AERO Solar and Cutting Edge.


There are thousands of traditional long-tail boats on Thailand’s waterways which are powered by old, polluting truck or car engines. This project’s aim is to provide the proof of concept for the operation of a solar-powered longtail boat, based on a traditionally constructed boat hull. In addition to its technical suitability, the boat’s economic operation shall also be demonstrated and a locally adapted financing and operating model shall be developed.
