Claim Text:
1. A system comprising: one or more photovoltaic cells configured to output direct current (DC) power; an optical element that concentrates light onto the one or more photovoltaic cells; a light diffuser that increases uniformity of the light concentrated by the optical element over the one or more photovoltaic cells; control circuitry configured to perform maximum power point tracking of the DC power and measure the DC power output by the one or more photovoltaic cells to produce a control signal; and a tracking controller configured to receive the control signal, and, based on the control signal, control a tracking motor that modifies at least one of an angular orientation of the one or more photovoltaic cells, an angular orientation of the optical element, and a distance between the optical element and the one or more photovoltaic cells, and wherein the tracking controller is further configured to, based on the control signal, change a distance between the light diffuser and the one or more photovoltaic cells.
