A solar powered electric ship system comprises an electric ship, multiple inflatable barges, and multiple inflatable non-imaging non-tracking solar concentrator based concentrating photovoltaic systems. The entire system is configured with the multiple inflatable non-imaging non-tracking solar concentrator based concentrating photovoltaic systems mounted on the inflatable barges, and with the inflatable barges mechanically and electrically connected to the electric ship. When in operation, the electric ship dragged the barges to navigate together with it, and have the inflatable non-imaging non-tracking solar concentrator based photovoltaic system to power it. The configuration dramatically reduce the battery bank size of the electric ship and make the portable floating concentrating photovoltaic system ultra-high efficiency, extremely low cost, and super light.

The invention relates to an energy supply system for a watercraft with a main energy converter that is configured for connection to an electrical system of the watercraft.
