A solar concentrator module comprising a front lens on its front face, a receiver
cell on its rear face and a reflector between the front lens and the receiver cell,
said reflector having inclined sidewalls along at least two opposite sides of the
receiver cell characterised in that the reflectors are truncated and in that the
sidewalls of the reflectors are inclined in such a way that, for a 0[deg] off-pointing,
solar rays are reflected on the inclined side walls of the reflectors before impinging
on the receiver cell, to produce a relatively uniform illumination on the receiver
cell for a range of off pointing acceptance angle superior to zero degree.
