Solar Energy
Although it is located at 55 degrees north latitude, a level not ususally considered to have an adequate solar resource, Malmö, Sweden is exploring the viability of using both thermal and PV solar systems.

Wall mounted solar panels These are vertically mounted, vaccuum tube solar collectors on the Salt and Brygge building in Western Harbor. Vaccuum tube collectors are more expensive than flat plate collectors, but also have higher efficiencies. Because of the tube's construction the mounting angle is not critical, making these ideal for wall mounted as well as roof top installations.

Roof mounted solar panels This is a closeup of some of the rooftop vaccuum tube solar collectors in Western Harbor. The open construction allows the wind to flow through the assembly, which is critical at this windy, seaside location. (photo by Mark Huppert, Catapult) Roof mounted solar panels
Close-up of solar panels This is a close-up of the solar panels, showing the individual evacuated glass tubes. The water is heated by running it against the back side of the black absorption panel which is positioned within each tube, and is mounted at the appropriate angle to maximize solar gain.

Photovoltaic panels The photovoltaic panels above these apartments in Malmö are on a sliding rack, so that they can be moved as necessary to provide shade during the summer. (photo by Mark Huppert, Catapult) Photovoltaic panels
Flat plate solar thermal panels These solar panels provide much of the hot water for the athletic complex in Western Harbor. (photo by Denise Fong, Candela) Flat plate solar thermal panels
Residential solar panels The solar thermal panels on the rooftops of the Tango Building in Western Harbor are tied into the neighborhood's district energy system, which provides both space heating and hot water for the units. (photo by Steve McConnell, NBBJ) Residential solar panels
