Concentration photovoltaic (CPV) systems are usually destined for large field applications, because the conventional optics applied require mandatory tracking, implying larger size systems and a high quantity of additional hardware. Thus, the use of CPV is very restricted when applied to small size systems, let alone selfstanding applications, such as solar street lights. However, if inexpensive, very versatile holographic optics are used in combination with other optical elements, it is possible to design a very compact Low CPV (LCPV) system. With the correct hologram design, this LCPV system is embedded into the pole of a stand-alone or grid-connected solar street light. The advantage towards conventional solar street lights is, therefore, a much lighter, more aesthetic product, with less need for solar cell area (concentration factor in holographic street lights is 3X) and less need for wind resisting foundations. This worldwide novelty can reduce costs by half. This work deals with the design aspects of such a street light. Preliminary experimental results concerning hologram performance, theoretical calculations of module performance, as well as structural resistance simulations are presented, together with cost calculations. Such results show a high potential of the new holographic LCPV street light design.
