A method and apparatus for operating a photovoltaic cell array provide for collecting power generated by each group of at least one but less than all of the cells of the array using each of a plurality of controllers, one controller for each group; converting the collected power at each controller to have a common output parameter, the common output parameter value being greater than the value of the same parameter at each of the individual cells; and combining the outputs from the controllers to generate an output for the array. Each controller thus has connected to it a group of one or more, but less than all, of the photovoltaic cells of the array, and the outputs of the controllers are connected preferably in parallel but potentially in series as well. The cells connected to the controllers are also connected in series, parallel, or a combination of the two. In this manner, the array output can be at or near its optimum power with each group of photovoltaic cells operating near their peak performance and under operating conditions potentially different from each other group of photovoltaic cells.
