A method of performing a service scan for available channels across a bandwidth of an input signal, the method comprising the steps of: acquiring a power spectrum of the input signal bandwidth; analyzing the power spectrum to identify a list of candidate channels, each candidate channel being identified by at least a center frequency; processing each of the candidate channels in a receiver unit to extract service information, if present, relating to the candidate channel; and storing the service information for the channel in a memory.

A photovoltaic assembly is disclosed which comprises a string formed from a plurality of series-connected photovoltaic generators, and a hierarchical structure of power-exchange units, which each exchange power between neighboring photovoltaic generators or groups of photovoltaic generators. The photovoltaic generators may be individual solar cells or a plurality of series-connected solar cells arranged as a segment. To compensate for differences in output between segments for instance due to partial shading, power-exchange units, such as DC-DC converters, are arranged across neighboring segments, such that each power-exchange unit effectively sources or sinks current between neighboring segments to current-match the string. To avoid unnecessary 'rippling' of power matching along many power-exchange units and the associated power loss due to many power-exchange units operating at less than 100% efficiency, the power-exchange units are arranged in a hierarchical structure. A method of operating such a photovoltaic assembly is also disclosed.
