It is a modified version of a flat plate collector, where a reflecting or refracting surface (known as a concentrator) is introduced between the solar radiation and the absorber. These collectors can significantly increase the radiation intensity from a low value to a much higher value, sometimes up to 10,000 times.
Solar energy collectors are crucial for converting solar radiation into usable forms like heat or electricity. There are two main types of collectors: non-concentration and concentrating collectors. In non-concentration collectors, the collector area and absorber area are the same.
There are two main types of collectors: non-concentration and concentrating collectors. In non-concentration collectors, the collector area and absorber area are the same. These collectors intercept solar radiation and absorb it without concentrating it.
A focusing collector is designed to capture solar energy with high intensity by using optical systems like reflectors or refractors. It is a modified version of a flat plate collector, where a reflecting or refracting surface (known as a concentrator) is introduced between the solar radiation and the absorber.
Flat Plate Collectors: Fixed tilted non-concentration collectors are used for temperatures below 100 °C. They can utilize both direct and diffuse solar radiation. These collectors are installed in a fixed tilted position, ideally facing the equator, to maximize efficiency and capture sunlight throughout the day.
The absorber, usually a collector pipe with a selective absorber coating, is placed at the focus to capture the concentrated solar energy. Parabolic trough collectors can vary in size, with reflector units typically being 3 to 5 meters long and 1.5 to 2.4 meters wide.
the elliptical cross-section of the collector reduces the level of thermal stresses arising. Thus, by varying the geometric shape of the cross-section, it is possible to reduce the level of thermal …
