Recreation Center in Germany Powers with Solar

The Steinhude Sea Recreation Facility building is only about 3,500 square feet with services for public toilets, lifeguard facilities, a small cafe, an observation deck, boat storage and a generator for supplemental power for the kitchen. Its photovoltaic system provides enough power for the building needs, as well as for recharging a fleet of eight solar-powered rental boats. There's even excess power to sell back to the grid. The PV panels (153 square meters in surface area) are integrated into and stretched along a sweeping roof that also provides daylighting with its innovative glazing system. A natural gas turbine generator provides additional power for peak loads associated with the cafe. The project is located on the south shore of Steinhude Sea in north-central Germany; it is on the 46,000 square meter (11.4 acres) Bath Island, attached by a bridge to the mainland.

Solar-Powered Yacht Cruises the Seas on Less Diesel

Thanks to its innovative hull design, the WHY solar-powered yacht requires less power at cruising speed than a boat of equal size. Its diesel-electric propulsion is the most efficient motorization today, and the surface of the photovoltaic panels - almost 900 square meters - covers most of the boat’s auxiliary system needs.
Its PV power is estimated to save up to 200 tons of diesel per year. http://www.solaripedia.com/13/200/roof_goes_electric_on_solar_why_yacht.html
