A solar adsorption apparatus comprises a parallel array of adsorber tubes 7 and an array of pairs of reflectors 1, 1a, where each pair of reflectors has an axis parallel to the parallel array of absorber tubes. The reflectors are arranged such that a reflector surface of one pair of reflectors and a reflector surface of an adjacent pair of reflectors form a compound parabolic concentrator (CPC). In a first position, an adsorber tube is positioned within each CPC to receive reflected radiation, and each pair of reflectors forms a shaded area 12 with an adsorber tube positioned within the shaded area. The apparatus further comprises control means to move the pairs of reflectors relative to the array of adsorber tubes to a second position. In the second position, adsorber tubes that were in a shaded area in the first position are positioned to receive radiation from a CPC, and adsorber tubes that were positioned to receive radiation from a CPC in the first position are positioned within a shaded area. Preferably, the apparatus comprises flat regions (108, fig. 10) extending between reflectors to provide additional shade area, where photovoltaic (PV) cells may be mounted on the flat regions. |
