10b that this heat energy which would otherwise be wasted may be used a heat exchange mechanism may be utilized both as a cooling system for the photovoltaic apparatus and as a thermal power generator the use of such a heat exchange mechanism increases the overall energy efficiency of the solar collection apparatus by a large factor perhaps enough to change a non economic solar collection system into an efficient solar collection system it is further noted that where an arrangement such as described in relation to fig1 a and 10b is mounted upon a tracking mechanism at least one heat exchange pipe 1062 may further serve as an axis of rotation for example the arrangement may be rotatably coupled to a central north south aligned pipe 1062 b such that it may rotate to align to the sun during its apparent daily motion across the sky according to various embodiments systems may utilize a single active area or a plurality of active areas such as strips referring now to fig1 showing a fourth embodiment of a solar concentration system 1100 the solar concentration system 1100 of the fourth embodiment has a single larger active area 1112 and two wing reflectors 1150 a 1150 b flanking the active area 1112 the reflectors 450 a 450 b are supported by wings mounted to the support platform 1130 and may redirect impacting light towards the active area 1112 in this way the system may be retrofitted to existing solar collectors to redirect incoming solar radiation over a much larger apparent area to.
