Acceptance angle is the maximum angle at which incoming sunlight can be captured by a solar concentrator. Its value depends on the concentration of the optic and the refractive index in which the receiver is immersed.
An example of a Low Concentration PV Cell's surface, showing the glass lensing. Low concentration PV are systems with a solar concentration of 2–100 suns. [37] For economic reasons, conventional or modified silicon solar cells are typically used. The heat flux is typically low enough that the cells do not need to be actively cooled.
Thanks to these devices, light arriving on a large surface can be concentrated on a smaller cell. The intensity concentration ratio (or "suns") is the average intensity of the focused light divided by 1 kW/m 2 (reasonable value related to solar constant). If its value is X then the MJ current becomes X higher under concentrated illumination ...
According to the authors, this ratio is well approximated by ln(fQ s /Q c), where f is the combination of factors f s f ω t s /(2t c), in which f ω is the solid angle of the sun divided by π. The maximum value of f without light concentration (with reflectors for example) is just f ω /2, or 1.09 × 10 −5, according to the authors.
The factory was planned to be capable of producing enough solar collectors to provide 200 MW of power per month. [10] In March 2009, the German company Novatec Biosol constructed a Fresnel solar power plant known as PE 1. The solar thermal power plant uses a standard linear Fresnel optical design (not CLFR) and has an electrical capacity of 1.4 MW.
A parabolic trough is made of a number of solar collector modules (SCM) fixed together to move as one solar collector assembly (SCA). A SCM could have a length up to 15 metres (49 ft 3 in) or more. About a dozen or more of SCM make each SCA up to 200 metres (656 ft 2 in) length. Each SCA is an independently-tracking parabolic trough. [9]
A luminescent solar concentrator. A luminescent solar concentrator (LSC) is a device for concentrating radiation, solar radiation in particular, to produce electricity. . Luminescent solar concentrators operate on the principle of collecting radiation over a large area, converting it by luminescence (specifically by fluorescence) and directing the generated radiation into relatively small ...
