Abstract
A PV solar panel system with reflectors includes racks, each of which may hold a solar panel and two reflectors, a support frame which enable the racks to be installed on in a swing method so that the racks can be tilted around horizontal axes (parallel to the ground) , and a four-bar linkage system which enables the racks to be tilted in such a way that the solar panels face sunlight throughout a day. The solar panel functions as a conventional or standard solar panel under all weather conditions when a track system is cooperated in the system. The reflector is a rectangular flat panel and has a fixed, but optimized, angle with respect to the solar panel so that it may be tilted with the solar panel, reflecting extra sunlight onto the solar panel, hence improving the efficiency of the system at a low cost.
Description
Title: PV SOLAR PANEL SYSTEM WITH REFLECTORS
[001] This invention relates to photovoltiac cell solar panels. The invention provides a PV solar panel system with reflectors, in which reflectors are attached to solar panels to reflect sunlight onto the panels, thus enhancing the efficiency of the panels at a low cost.
BACKGROUND TO THE INVENTION
[001] This invention relates to photovoltiac cell solar panels. The invention provides a PV solar panel system with reflectors, in which reflectors are attached to solar panels to reflect sunlight onto the panels, thus enhancing the efficiency of the panels at a low cost.
BACKGROUND TO THE INVENTION
[002] Solar power from photovoltiac cells is currently under serious consideration worldwide as the near future renewable energy due to rapid development of photovoltaic technology in the last few years. However, cost remains the main barrier to application of the solar power because the cost is still significantly higher than that of fossil fuels.
[003] There are several ways to decrease the cost of photovoltiac cells.
Since crystalline silicon comprises approximately 40% the price of photovoltaic cells, significant cost decrease of the crystalline silicon material is essential for the cost reduction. Alternatively, high efficient cell structure such as multiple layer cells or new inexpensive cell materials may be developed in replace of the present polycrystalline silicon cells to improve the cell efficiency or decrease the cost.
Since crystalline silicon comprises approximately 40% the price of photovoltaic cells, significant cost decrease of the crystalline silicon material is essential for the cost reduction. Alternatively, high efficient cell structure such as multiple layer cells or new inexpensive cell materials may be developed in replace of the present polycrystalline silicon cells to improve the cell efficiency or decrease the cost.
[004] The other method to decrease the cost is to increase the amount of sunlight hitting the solar cells so that the efficiency of the solar cells is improved. Since the highest amount of incoming solar radiation that falls on the outer surface of Earth's atmosphere, is in a plane perpendicular to the sunlight rays (called solar constant), the solar panel should be optimized toward the sun (the panel surface is perpendicular to the rays). This may be achieved through a sophisticated tracking system. Alternatively, more sunlight may be brought onto the 35 solar panel through concentrators or reflectors. In such systems, in comparison with standard solar panel systems, less expensive cell material is used for same amount of power output and, thus, the cost is decreased.
40 [005] In the present invention, conventional or standard solar panels are used in combination with reflectors and one axis tilting system to optimize the efficiency of the solar panel system at a low cost.
[006] In a preferred version, the system may contain two or more racks on each of which a PV cell panel and two reflectors may be installed.
50 [007] Ina preferred version, the PV cell panel on the rack is a rectangular panel with its long edges parallel to the ground (the earth surface).
[008] In a preferred version, the reflector is a rectangular flat panel which have high overall reflection in the visible and infrared wavelength 55 ranges.
[009] In a preferred version, the reflectors are installed onto the rack with their long edges along the two long edges (i.e., the bottom edge and the top edge) of the solar panel and an optimized angle with 60 respect to the solar panel.
[0010] So installed solar panel and reflectors enable the solar panel to function as a conventional or standard solar panel under all weather conditions and the reflectors reflect extra sunlight onto the solar 65 panel when the solar panel faces the sun.
[0011] The racks are installed onto a support frame, which set up in the ground, in a swing way so that the racks may be tilted to keep the solar panel facing the sunlight throughout a day.
[0012] The racks may be joined together with a bar in a pivot method to create a four-bar linkage system which may be driven by a motor driving system controlled by a sensor to tilt the racks.
[0013] In respect of the size and efficiency of a solar panel in such a system, the power output of the solar panel is expected to be doubled through the reflected sunlight.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0014] By way of further explanation of the invention, exemplary embodiments of the invention will now be described with reference to the accompanying drawings, in which:
Figure 1 is a diagram showing an "A" shape frame which is a basic unit for constructing a rack.
Figure 2 shows construction of the rack.
Figure 3 shows a cross sectional view of the attachment of a solar panel and two reflectors onto the rack.
Figure 4 shows sunlight rays and reflection of the rays onto the solar 95 panel through the reflectors.
Figure 5 is a diagram showing construction of a support frame.
Figure 6 shows how the racks are installed onto the support frame and 100 connected with linkage bars to complete the solar system.
Figure 7 shows how the joints and connections form a four-bar linkage system (AB//DC and AD//BC) which may be used to tilt the racks.
105 Figure 8 shows how the racks are tilted through the four-bar linkage system so that the solar panel faces low angle sunlight rays.
Figure 9 shows how the racks are tilted through the four-bar linkage system so that the solar panel faces high angle sunlight rays.
[0015] The structure shown in the accompanying drawings and described below is an example which embodies the invention. It should be noted that the scope of the invention is defined by the accompanying claims, 115 and not necessarily by specific features of exemplary embodiments.
[0016] Figure 1 shows a basic unit structure in the system termed as "A" shape frame. It consists of two leg bars 2 and a middle bracing bar 1. These bars may be made from metal beam, plate, bar, angle or 120 tubes, and also plastic material or similar although T beam is preferred.
A piece of short tube 4 is placed at the top of the "A" shape frame for a purpose of assembly. The bars and tube may be joined together by welding, adhesion or fastening methods to form the `A" shape frame.
The "A" shape frame may be also formed by extrusion, forming or moulding, 125 particularly when plastic materials are used.
[0017] Figure 2 shows such formed "A" shape frames are joined together to form a rack. Part 5 is preferably a tube or round bar, but part 6 is preferably a T beam although other shapes may be used. Parts 5 and 130 6 join a row of the "A" shape frames together at an equal space by welding, adhesion or fastening methods to form the rack.
[0018] Two shaft journals 3 in Figure 2 are attached to the rack at its two ends for a purpose to install the rack onto a support frame 135 in such a way that the rack may swing on the support frame.
[0019] A solar panel 7 in Figure 3, preferably a high efficiency rectangular solar panel, is attached to the rack through part 1 and two reflectors 8 in Figure 3 are attached to the rack through part 2.
140 Brackets and fasteners may be used in the attachments.
[0020] Reflector 8 in Figure 3 is a rectangular flat panel which may be made from the following materials or similar: a stainless steel foil or plate with a mirror-like surface, an aluminium foil or plate with 145 a mirror-like surface which is protected with either a transparent polymer finish or an oxide coating layer against weather conditions, silver polymer and an aluminium coated plastic panel. In any cases, the reflecting surface should have high overall reflection in the visible and infrared wavelength ranges.
[00211 The angles 8 and a in Figures 1 and 3 are related to each other (0=90 + a/2) and may be chosen in such a way, in combination with considering the size of the reflector and the solar panel, the reflected sunlight through the reflectors 8 should be fully reflected onto the 155 solar panel surface 7 and also fully cover the surface, as illustrated in Figure 4. Preferably a is larger than 40 and smaller than 70 [0022] A support frame in Figure 5, similar to a swing frame, is constructed using metal beams, plates, bars, angles or tubes by welding or fastening 160 methods. The support frame is set up in the ground with concrete.
Front posts 9 should preferably have an angle between 30 and 60 with respect to the ground (the earth surface). Bush seats 10 are attached onto the front posts 9 by welding or fastening methods for a purpose to hold the racks in a swing mechanism.
[0023] In the system of Figure 6, the rack 12 is installed onto the support frame 13 through inserting its two journals 3 into bush housings on front posts 9 so that the rack may swing along an axis parallel to the ground through the journal/bush joints (3/10) [0024] In the system of Figure 6, support frame 13 may be designed in such a way that several racks 12 may be installed parallel to each other.
In such a case, the racks should be properly spaced so that they don't block sunlight to each other when they are tilted with the solar panel 175 surfaces toward the sun.
[0025] In the system of Figure 6, when two or more racks 12 are installed onto the support frame 13, bar 11 may join the racks 12 at the top of the "A" shape frames in a pivot method through part 5. Such kind of 180 joints creates a four-bar linkage system, as marked with A, B, C and D in Figure 7. When the bar 11 moves back and forth, as marked with arrow dash lines, the racks are tilted around A and B, as marked with double arrow dash lines.
185 [0026] A motor driving system controlled by a sensor may be used to drive the bar 11 so that the racks 12 are tilted to keep the solar panels toward the sun throughout a day. Figure 8 shows the solar panels are tilted with the racks 12 toward low angle sunlight rays in morning or afternoon and Figure 9 shows the solar panels face high angle sunlight 190 rays at noon.
40 [005] In the present invention, conventional or standard solar panels are used in combination with reflectors and one axis tilting system to optimize the efficiency of the solar panel system at a low cost.
[006] In a preferred version, the system may contain two or more racks on each of which a PV cell panel and two reflectors may be installed.
50 [007] Ina preferred version, the PV cell panel on the rack is a rectangular panel with its long edges parallel to the ground (the earth surface).
[008] In a preferred version, the reflector is a rectangular flat panel which have high overall reflection in the visible and infrared wavelength 55 ranges.
[009] In a preferred version, the reflectors are installed onto the rack with their long edges along the two long edges (i.e., the bottom edge and the top edge) of the solar panel and an optimized angle with 60 respect to the solar panel.
[0010] So installed solar panel and reflectors enable the solar panel to function as a conventional or standard solar panel under all weather conditions and the reflectors reflect extra sunlight onto the solar 65 panel when the solar panel faces the sun.
[0011] The racks are installed onto a support frame, which set up in the ground, in a swing way so that the racks may be tilted to keep the solar panel facing the sunlight throughout a day.
[0012] The racks may be joined together with a bar in a pivot method to create a four-bar linkage system which may be driven by a motor driving system controlled by a sensor to tilt the racks.

[0015] The structure shown in the accompanying drawings and described below is an example which embodies the invention. It should be noted that the scope of the invention is defined by the accompanying claims, 115 and not necessarily by specific features of exemplary embodiments.

[0017] Figure 2 shows such formed "A" shape frames are joined together to form a rack. Part 5 is preferably a tube or round bar, but part 6 is preferably a T beam although other shapes may be used. Parts 5 and 130 6 join a row of the "A" shape frames together at an equal space by welding, adhesion or fastening methods to form the rack.
[0018] Two shaft journals 3 in Figure 2 are attached to the rack at its two ends for a purpose to install the rack onto a support frame 135 in such a way that the rack may swing on the support frame.
[0019] A solar panel 7 in Figure 3, preferably a high efficiency rectangular solar panel, is attached to the rack through part 1 and two reflectors 8 in Figure 3 are attached to the rack through part 2.
140 Brackets and fasteners may be used in the attachments.
[0020] Reflector 8 in Figure 3 is a rectangular flat panel which may be made from the following materials or similar: a stainless steel foil or plate with a mirror-like surface, an aluminium foil or plate with 145 a mirror-like surface which is protected with either a transparent polymer finish or an oxide coating layer against weather conditions, silver polymer and an aluminium coated plastic panel. In any cases, the reflecting surface should have high overall reflection in the visible and infrared wavelength ranges.
[00211 The angles 8 and a in Figures 1 and 3 are related to each other (0=90 + a/2) and may be chosen in such a way, in combination with considering the size of the reflector and the solar panel, the reflected sunlight through the reflectors 8 should be fully reflected onto the 155 solar panel surface 7 and also fully cover the surface, as illustrated in Figure 4. Preferably a is larger than 40 and smaller than 70 [0022] A support frame in Figure 5, similar to a swing frame, is constructed using metal beams, plates, bars, angles or tubes by welding or fastening 160 methods. The support frame is set up in the ground with concrete.
Front posts 9 should preferably have an angle between 30 and 60 with respect to the ground (the earth surface). Bush seats 10 are attached onto the front posts 9 by welding or fastening methods for a purpose to hold the racks in a swing mechanism.
[0023] In the system of Figure 6, the rack 12 is installed onto the support frame 13 through inserting its two journals 3 into bush housings on front posts 9 so that the rack may swing along an axis parallel to the ground through the journal/bush joints (3/10) [0024] In the system of Figure 6, support frame 13 may be designed in such a way that several racks 12 may be installed parallel to each other.
In such a case, the racks should be properly spaced so that they don't block sunlight to each other when they are tilted with the solar panel 175 surfaces toward the sun.
[0025] In the system of Figure 6, when two or more racks 12 are installed onto the support frame 13, bar 11 may join the racks 12 at the top of the "A" shape frames in a pivot method through part 5. Such kind of 180 joints creates a four-bar linkage system, as marked with A, B, C and D in Figure 7. When the bar 11 moves back and forth, as marked with arrow dash lines, the racks are tilted around A and B, as marked with double arrow dash lines.
185 [0026] A motor driving system controlled by a sensor may be used to drive the bar 11 so that the racks 12 are tilted to keep the solar panels toward the sun throughout a day.
