Hanergy's CIGS thin-film modules with lightweight and flexible characteristics can be well adapted to the curvature of the cruise ship. They feature easy installation and high aesthetic value and are wind, high temperature and humidity resistant, and can sustain a load. They are easy to be installed, maintained and cleaned. No cracks due to ship vibration, good performance under weak light and stable power generation. All electricity needed on the boat can be supplied by thin-film solar modules. After calculation, under the same motor power, the operating cost of a solar ship is only 17% compared with that of an ordinary diesel-powered ship, and the noise in the cabin is only about 60 decibels, which ensures a quiet environment. The whole ship is essentially vibration free and truly realizes zero exhaust emissions.
