Abstract: A system including an array of solar cells having positive and negative rails. A plurality of intermediate nodes are positioned adjacent positive and negative rails of solar cells in the array of solar cells. A plurality of switches are positioned to couple positive nodes to positive rails, couple negative nodes to negative rails and couple positive and negative rails to intermediate nodes.

Abstract: A system includes a solar power subsystem that receives power from one or more solar power arrays. A storage control subsystem is coupled to the solar power subsystem to charge a battery from the power received by the solar power subsystem. A grid power control subsystem having an AC to DC converter receives power from a power grid and provides DC voltage to the storage control subsystem. A balance of system control system controls the amount of power received from the power grid as a function of a load, battery charge and received power by the solar power subsystem. The solar array and battery may be sized to provide sufficient power under normal operating conditions, with power being drawn from the grid during abnormal operation conditions.

Abstract: A system includes a power distributor having a power collection rail and a power management rail disposed within a track. A first module having a solar collector is adapted to couple to the track and electrically connect to the power collection rail. A rechargeable battery provides direct current (DC) power to the power management rail. A controller is coupled the battery and to the track to receive power from the power collection rail to recharge the battery. Various modules having solar collectors, batteries and devices may be coupled to the track.

Abstract: Colorization of a solar cell is achieved by modifying a layer proximate an active layer of the solar cell. The color attribute may be obtained by selecting one or more narrow bands of wavelengths in the visible color spectrum to be reflected from the surface of the solar cell unit that results in a specific color or combination of colors at various angles. The spectrum of light reflected from the active solar cell area is controlled through the use of filters that reflect only limited portions of the spectrum, thereby minimizing the effect of reflected light on the overall efficiency of the solar cell.
