A
photovoltaic system including a photovoltaic
cell, and an electronic module connected to the photovoltaic
cell. The electronic module is adapted to produce at least one
control signal indicative of electrical power being generated by the photovoltaic cells. A tracking controller is adapted to receive the
control signal(s) and based on the
control signal(s), the controller is adapted to control a tracking motor for adjusting the
system so that electrical power generated by the photovoltaic cells is increased. The
photovoltaic system may include an optical element, adapted for concentrating
solar light onto the photovoltaic cells. The electronic module preferably performs
direct current (DC) to
direct current (DC) power conversion and
maximum power point tracking by electrical power, current, or
voltage at either their inputs or their outputs. Alternatively, the tracking controller is configured to also perform
maximum power point tracking by increasing to a local maximum electrical power by varying at least one of (i) current or
voltage output from the photovoltaic
cell or (ii) current or
voltage output from the electronic module.
