The direction of a solar light tracking sensor is set easily with high accuracy. A solar light tracking guide () is installed on the optical axis () of the reflected light collected by a heliostat (). An optical telescope () is so attached to the rear end part of the guide () as to be aligned with the guide axis (C) of the guide (). The posture of the solar light tracking guide () is so adjusted that a cross provided in the field of view of the telescope () agrees with the center () of the light collection target position and fixed to the base (). Then, a solar light tracking sensor () is fastened to the rear end part of the guide () in place of the optical telescope ().

Provided is a cleaning robot system and a method of controlling the same for economically cleaning, with high workability, plate-shaped members, such as solar cell panels and reflecting mirrors used in photovoltaic power generation and solar thermal power generation systems. A cleaning robot system () for cleaning planar or curved plate-shaped members (), () that are panels for photovoltaic power generation or reflecting mirrors for solar thermal power generation includes: a large number of cleaning robots () each having a function to travel on each of the plate-shaped members () which are to be cleaned and a function to clean the plate-shaped members (); and an arranging robot () having a conveying function to move any of the cleaning robots () from a first one () of the plate-shaped members to a second one () of the plate-shaped members. Each of the cleaning robots () has a suction mechanism for performing cleaning while attaching onto one of the plate-shaped members (), and the large number of cleaning robots () and a smaller number of the arranging robots () than that of the cleaning robots () cooperate together to clean the plate-shaped members () placed in a photovoltaic power generation or solar thermal power generation plant.
