Abstract
A solar panel has n rows of solar cells in a regular grid array. The cells constituting each row are wired in parallel, the rows are wired in series and an equalizing network of n-1 capacitors are connected in electrical series. In a first configuration, a network of switches connects a first capacitor across the first row, and a second capacitor across the second row, and so on until the n-1th capacitor is connected across the cells of the n-1th row. In a second configuration, the switch network connects the first capacitor across the second row, and the second capacitor across the third row, and so on until the n-1th capacitor is connected across the nth row. This causes the voltage across each row to be substantially equal to the voltage across every other row. Since equal voltage is a hallmark of parallel connection, this voltage equalized series connection is referred to as a virtual parallel connection.
