Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The present invention will be understood and appreciated more fully from the following detailed description taken in conjunction with the drawings in which:

[0011] FIG. 1 is a simplified pictorial illustration of a solar panel array, constructed and operative in accordance with an embodiment of the present invention;

[0012] FIG. 2 is a simplified pictorial illustration of a solar panel array, constructed and operative in accordance with another embodiment of the present invention; and

[0013] FIG. 3 is a simplified pictorial illustration of a light fixture powered by any of the solar panel arrays of the invention, in accordance with an embodiment of the present invention.

DETAILED DESCRIPTION OF EMBODIMENTS

[0014] Reference is now made to FIG. 1, which illustrates a solar panel array 10, constructed and operative in accordance with a non-limiting embodiment of the present invention.

[0015] The solar panel array 10 includes a plurality of m sub-arrays 12 of solar panels 14, or as shown in the drawing, n solar panels 14(1) up to 14(n). In each sub-array 12, the solar panels 14 are electrically connected in series. In the illustrated embodiment, each sub-array 12 is curved (e.g., concave), but the invention is not limited to this shape, and the sub-arrays can be convex or any other regular or irregular shape, curved or not curved. The sub-arrays 12 may be electrically connected to one another in parallel or serial according to the battery charging requirement.

[0016] The solar panels 14 are any kind of photovoltaic cell for generating electricity from solar energy, such as but not limited to, monocrystalline, polycrystalline or amorphous film cells.

[0017] For each sub-array 12 of solar panels 14, the solar panels 14 have unequal shapes, but the areas of all solar panels 14 are equal. In other words, the area of solar panel 14(1)=the area of solar panel 14(2)=the area of solar panel 14(3)= . . . =the area of solar panel 14(n). For example, the length of the lowest solar panel 14(1) is longer than the length of solar panel 14(2), but the width of the lowest solar panel 14(1) is less than the width of solar panel 14(2) so that the areas are the same. The uppermost solar panel 14(n) has the smallest length and largest width (length being the horizontal dimension and width being the vertical dimension).

[0018] Reference is now made to FIG. 2, which illustrates a solar panel array 20, constructed and operative in accordance with another non-limiting embodiment of the present invention.

[0019] Similar to the embodiment of FIG. 1, solar panel array 20 includes a plurality of sub-arrays 22 of solar panels 24, n solar panels 24(1) up to 24(n). In each sub-array 22, the solar panels 24 are electrically connected in series. In the illustrated embodiment, each sub-array 12 is flat, but could be other shapes. The sub-arrays 22 may be electrically connected to one another in parallel.

[0020] For each sub-array 22 of solar panels 24, the solar panels 24 have unequal shapes, but the areas of all solar panels 24 are equal. The uppermost solar panel 24(n) has the smallest length and largest width (length being the horizontal dimension and width being the vertical dimension). In the top horizontal array, all solar panels have equal shapes and areas.

[0021] Reference is now made to FIG. 3, which illustrates a light fixture 30 powered by solar panel array 20 (but could alternatively by powered by solar panel array 10), constructed and operative in accordance with a non-limiting embodiment of the present invention.

[0022] The solar panel array 20 is mounted at the top of the light fixture 30 and generates electricity which is stored in one or more batteries 32, which are in electrical communication with solar panel array 20. The one or more batteries 32 power one or more lights 34 (such as, but not limited to, LED lights). The batteries 32 may be located at the bottom of the fixture 30 or at any other convenient location. The lights 34 may be located along sides of the fixture 30 or at any other convenient location. The light fixture 30 may be mounted on a pole or mounting bracket 36.
