Double-Sided Solar Panels

solar_panel_01.jpgDouble your solar power? These double-sided solar panels, exhibited at World Expo 2005 are actually only 1.3 times as effective as regular, single-sided ones. The panels collect light on both their sides, and are installed vertically. This means that frames and other materials can be reduced in the installation. Another advantage of vertical installation is fewer problems with accumulated snow, dirt, bird droppings and the like. That last one is a big plus in my book. :: Solar Panel Exhibit [by Justin Thomas]
