To control a power network having a photovoltaic system, a time curve of a light radiation of the photovoltaic system is determined, wherein an increase of the time curve in relation to a reference curve of the light radiation is detected. As a result of the detection of the increase, a preparatory measure is then introduced to prepare the power network for an upcoming power drop of the photovoltaic system.

An apparatus for wet treatment of sheets or strips of photographic material has a small-volume treating chamber bounded by pairs of advancing rollers at its inlet and outlet ends. A lower wall of the chamber extends between the lower rollers of the pairs of advancing rollers and sealing lips bridge the gaps between such lower wall and the respective lower rollers. Treating liquid is admitted laterally into the chamber, transversely of the path of advancement of photographic material and at about the level of such path.
