Abstract: A solar module cleaner can be configured for cleaning reflective surfaces of solar concentrator reflectors. The cleaner can include at least one cleaning module having a cleaning surface extending in a curved configuration corresponding to a curvature of the solar concentrator reflector. The cleaning surface can be configured to displace debris resting on the reflective surface. The cleaner can include fluid delivery devices for discharging a cleaning fluid onto the reflective surface. The cleaner can be configured to clean solar energy receivers associated with a solar concentrator reflector. Additionally, the cleaner can be configured to simultaneously clean a plurality of parallel solar concentrator reflectors. Optionally, the cleaner can be configured to simultaneously clean a plurality of solar energy receivers and a plurality of solar energy concentrators.
