Linear parabolic collector systems

Currently, the most suitable technology for electrical energy production by ther­modynamic systems is one which uses linear parabolic collectors [45, 50, 53]. These collectors are composed of a linear concentrator with a parabolic profile whose reflecting surface follows the Sun rotating on a single axis. The concentra­tor is fixed on a support structure which guarantees the correct processing during windy […]

The solar constant

The solar constant Ics is the average energy radiated by the Sun per time unit on a unitary surface situated outside the Earth’s atmosphere and perpendicular to the Sun’s rays. It measures 1367 W/m2 . Considering the atmospheric phenomenon of absorption and diffusion and the Sun’s inclination above the horizon, on the Earth’s soil the solar constant reaches a maximum […]
