Concentrated Industrial and Commercial Solar Lighting System

Solar concentrating systems integrated with buildings is different from the common solar systems integrated with buildings because of the special structure. At the same time, it can obtain the advantage of the solar concentrators.

The LSC is a radiation concentration device for the production of electricity power. Luminescent solar concentrators work on a large-area radiation collection principle, transformed by luminescence (specifically fluorescence) and directs the generated radiation to a relatively small output target .

With the development of the energy saving buildings, the solar energy integrated with buildings has attracted a lot more attentions. Solar concentrating systems integrated with buildings is different from the common solar systems integrated with buildings because of the special structure.

One of the key features for the concentrating solar thermal systems is that they are aimed at building application with a wider acceptance angle for the requirement of the static installation. In this case, CPC as a typical low-concentrating ratio concentrator is a good choice.

Compared with the traditional flat PV module, the concentrating PV technology offers more design imaginations for combing the natural daylighting, and the solar concentrators are usually made of the transparent material such as polymethyl methacrylate (PMMA).

Section of a concentrating photovoltaic element for wall integration, with a concentration ratio of 3 × G denotes the incoming irradiation and v is the effective solar height. The photovoltaic module is tilted forwards by 20°. The depth, d; of the wall element is 180 mm and the opening of a single concentrating element, h; is 550 mm . Fig. 32.
