Patent US 7,709,727

The invention relates to a circuit arrangement for controlling/regulating photovoltaic systems (10b) which comprise a plurality of solar generators (14b) connected in series or/and connected in parallel. In order to prevent power loss of solar generators, which is based on the fact that not all solar generators are operated in the MPP thereof, each solar generator is associated with a variable energy bypass (68b) that is controlled/regulated in such a manner that each solar generator (14b) is operated continuously in its respective current specific MPP.
