A micro-concentrator module includes a cover glass provided with solar cells on one side thereof. The cover glass is adapted to hover above a substrate containing an array of MEMS based reflectors. Springs between the cover glass and the substrate displace the cover glass from a stowed position during transport to a deployed operational position above the substrate. Tethers connecting the cover glass with the substrate limit the displacement of the cover glass to a distance corresponding to the focal length of the reflectors.
