The solar collector is the main component of a solar system. It transforms radiant energy from the sun, in the spectral range 0. 3 – 3μm, into usable heat (Fig. 1). The density of fluxes involved is low, at a maximum of the order of 1 kW/m2 (1000 times less than in the case of nuclear reactors). Heat losses depend essentially on temperature levels.

Solar thermal collectors are used to heat up a fluid, generally water or a mixture of glycol and water depending of the configuration of the solar thermal system. They are adopted for many applications in both industrial and residential sectors. Many typologies exist in order to comply with heterogeneous needs. All have a common operating principle: to

Concentrating Solar Collectors
1985This chapter provides an introduction to concentrating solar collectors. The optical and thermal characteristics are described in relatively simple terms, and copious references to the more technical literature are given. A unified framework is used for analyzing the performance of all solar collector types; it involves optical efficiency, U-value, and

Fundamental to the design of solar trough collectors is that a suitable structure must be provided for positioning and support of mirrors, as well as pipes for transporting heat transfer fluids. These elements and related hardware are basic to the level of investment necessary for fabrication of collectors.
