To develop concentrating photovoltaic systems for building integration applications, two optical devices
are proposed. The concentrators are based in stationary linear Fresnel lenses and secondary CPC. The
moving focal area is ten times smaller than the Fresnel lens aperture. Concentrator characteristics are
studied in detail: shadowing effect, placement of the focal area and optical concentration efficiency.
The main contribution of this paper is the three-dimensional optical analysis of the non-imaging concentrating
systems. In terms of solar radiation, photovoltaic moving modules placed in the focal area of stationary
concentrators are compared with simply fixed photovoltaic modules. In favourable weather
locations, the beam radiation incident on the concentrating modules would be a large percentage, more
than 50%, of the global radiation received by the fixed photovoltaic devices.
