LOCALIZED POWER POINT OPTIMIZER FOR SOLAR CELL INSTALLATIONS

摘要

In one embodiment, a solar cell installation includes several groups of solar cells (413). Each group of solar cells (413) has a local power point optimizer (402) configured to control power generation of the group. The local power point optimizer (402) may be configured to determine an optimum operating condition for a corresponding group of solar cells (413). The local power point optimizer (402) may adjust the operating condition of the group to the optimum operating condition by modulating a transistor, such as by pulse width modulation, to electrically connect and disconnect the group from the installation. The local power point optimizer (402) may be used in conjunction with a global maximum power point tracking module (414).
