Concentration photovoltaic (CPV) systems are usually destined for large field applications, because the conventional optics applied require mandatory tracking, which implies larger size systems, larger land use and a high quantity of additional hardware. Thus, the use of CPV is very restricted when applied to small size systems, let alone integrated applications. However, the very compact Low CPV (LCPV) module named SoHo3X has shown that it can avoid tracking by using holograms, and yet provide up to 50% more capacity factor than a conventional, fixed flat module, at very competitive costs. This work presents the performance measurements for the first time and uses them to calculate performance at BIPV representing positions, tilts, orientations and latitudes, in order to show how it can be used both in BIPV and also as integrated photovoltaics in urban furniture. The advantage versus integrating conventional modules is not only a higher production, but also a much lighter, more aesthetic product, with less need for solar cell area (concentration factor is around 3X). Conclusion is that SoHo3X shows a much better performance in most cases, with a few exceptions for vertical position at high latitudes. Mechanical load simulations have also been carried out, showing that SoHo3X complies with the strictest mechanical load regulations, fulfilling class I mechanical stability for wind loads, in opposition to conventional flat PV modules.
