Galapagos Marine Solar Energy: "A recent oil spill dumped thousands of gallons of fuel into the fragile waters [off the Galapagos] .. One recent example of a trend toward renewable energy on the islands is a new 18-person Catamaran designed for eco-tourism and that was retrofitted with 20 Shell Solar photovoltaic (PV) modules, two Xantrex SW 4048J inverter/chargers for on-board power. The father and son team of Guillermo and Alejandro Botta led a group of craftsmen from Guayaquil, Ecuador, in the construction of the solar-powered catamaran, a first for Ecuador's naval industry. The vessel is used to ferry tourists through the Galapagos Islands and includes a dive platform for scuba diving.

Because the Archipell sails in a highly-sensitive ecosystem, the team decided to build it using a fiberglass hull and solar powered electric motors. The increased weight of a steel hull would have put additional strain on the solar-powered motors as well.  Twenty solar panels placed across the roof charge a bank of batteries and are connected to the Xantrex inverters which in turn supply electricity to operate the vessel. The company said construction of the solar-powered ship has been described as a milestone for Ecuador's shipbuilding industry."  12:27:29 PM  permalink
