Eco Marine Power Co., Ltd. has commenced evaluation trials of its updated solar power system, Aquarius Marine Solar Power, and the first of several photovoltaic module technologies aboard a bulk cargo ship, according to the company's release.
The evaluation, initiated on 1 August 2025 in Fukuoka, Japan, is to run for 12 to 18 months, with the stated aim of demonstrating the practicality and performance of the revised solar power system under real maritime conditions.
The first PV module under evaluation is supplied by Merlin Solar Technologies Inc., whose mono‑crystalline silicon panels—both glass and non‑glass types—are described as flexible, lightweight and suitable for “peel & stick” deployment, engineered to endure tough and sub‑optimal conditions.
The panels were installed by Aries Marine using specially designed frames pre‑fitted to the vessel.
