Positioning Solar Thermal Collectors
If you're installing a solar thermal system in a location that gets a lot of direct sunlight and you're doing it on an industrial scale, you might want to consider concentrating collectors. Unlike normal collectors, these won't work with indirect sunlight, but they're a lot more efficient than any of the other types if your location, scale and budget allow their use. Concentrating collectors use the simple scientific principles of focusing light to concentrate the sun's energy onto a single point.
