Direct solar desalination produces distillate directly in the solar collector. This is known as the Solar Collector Loop. This cutaway view shows the MatrixAir transpired solar collector components and air flow. Fluorescence can also be used to redirect photons, see fluorescent solar collector. In 2014, Poland was ranked fourth in sales of solar collector installations among European countries. Solar collector surfaces coated with nanopillars are three times as efficient as nanowire solar cells. Each field utilizes 1128 solar collector arrays (SCA) sited on about . Different types of solar collector and their location (latitude) require different types of tracking mechanism. The 1840 Solar Collector Assemblies are each, yielding of total solar aperture. The solar collector melted snow which dripped into empty wine bottles. The Tower's sloped roof acts as a solar collector and is positioned facing south. The Decepticons are defeated when Spike sabotages the solar collector, destroying the energon cubes. The solar collector would feed an ion drive engine that would power the craft. The most common type of unglazed collector on the market is the transpired solar collector.
