A solar-powered lighting system includes a flexible, wrap-around, preferably self-stick panel of photovoltaic laminate applied to the outside surface of a light pole. An LED light fixture is connected preferably at or near the top of the pole and has the same or similar diameter as the pole. The LED light fixture has multiple columns and rows of LEDs and an interior axial space for air flow to cool the LEDs. The pole preferably also has vents and axial passage(s) for creating a natural updraft through at least a portion of the pole and the light fixture, for cooling of the photovoltaic panel interior surface, the LEDs, and/or other equipment inside the fixture or pole, and batteries that may be provided inside the pole or pole base. A purely or mainly decorative additional fixture, which emulates conventional outdoor light fixtures, may be provided on the lighting system, wherein the decorative additional fixture includes no, or only a minimal, light source. The lighting system has a sleek profile with few or no protrusions from the sides of the pole and from the LED light fixture, except for the optional decorative fixture that provides a conventional street light appearance even though the main light source is the LED fixture.

A photovoltaic element which directly converts an optical energy such as solar light into an electric energy. After many uneven sections are formed on the surface of an n-type crystalline silicon substrate (1), the surface of the substrate (1) is isotropically etched. Then the bottoms (b) of the recessed sections are rounded and a p-type amorphous silicon layer (3) is formed on the surface of the substrate (1) through an intrinsic amorphous silicon layer (2). The shape of the surface of the substrate (1) after isotropic etching is such that the bottoms of the recessed sections are slightly rounded and therefore the amorphous silicon layer can be deposited in a uniform thickness.

The present solar light assembly uses a unique solar light box that has an upper step which visually frames a lower step. The lower step has a deep cavity that houses most of the components of the solar light assembly, such as an LED light source and a 12 volt battery. The lower step is completely covered by a solar panel which functions as a lid in addition to gathering energy that is stored in the battery. The upper step conceals the solar panel from view by a passerby. There is a rain barrier ridge substantially around an opening to the lower step's deep cavity to prevent water that may collect in the upper step from entering the deep cavity. The solar light box is large enough to house additional components, such as a motion sensor or a camera. In the preferred use of the solar light assembly, the solar light box is mounted to a pole that extends over the top of a cluster box unit.

A power supply unit composed so that outputs from a plurality of cells having different output characteristics are output from common terminals and so that a decrease in energy efficiency caused by connecting the cells is suppressed to the utmost is provided. After outputs of a plurality of cells 10a to 10c having different output voltages and output currents are adjusted to have the same output voltage value, the outputs are output to terminals 4 and 5 so as to match the parallel connection.
