Figure 2 depicts an enlarged fragment of the solar battery shown in figure 1.

Figure 3 shows a section a-a in figure 2.

Figure 4 shows the section b-B figure 2.

Figure 5 depicts the solar panel when folded.

Solar panel folding consists of several (e.g. four) of the same electrically interconnected fo elektricheskij panels 1 (Fig 1) with a protective film of the front surface, interconnected in series and/or parallel. Photovoltaic panel 1 contains many of the photoelectric converters 2 and fixed in the longitudinal direction with an interval of 3-5 cm on the basis of 3 of flexible material in the frame 4.

Each photovoltaic panel 1 is connected with the base 3 detachable fixing means, which are strips 5 tape Velcro fastened respectively on the basis of 3 and on the back side of each photovoltaic panel 1. Mount photovoltaic panels 1 to the base 3 by means of strips 5 tape Velcro shown in Fig. 4, 5A and 5B are two strips of tape, Velcro, respectively, with eyelets and hooks.

The frame 4 is composed of longitudinally and transversely spaced miscellaneous items 6, 7 connected to the base 3 with the possibility of turning (rotation), and is made of flexible material that is identical or similar to the base material 3, including hand tight fabric. Connection longitudinally and transversely spaced miscellaneous items 6, 7 with the base 3 of the machine stitching or adhesive connection allows their lapel (rotation) up to 180° respectively, relative to the seam or line connection (figure 3, 4). Frame 4 exclude damage to the PV panels 1 when folding the folding and transport of solar-b is tarei and generally represent a special collapsible bulkhead pockets.

In the specific example of implementation (figure 1) frame 4 can be made of longitudinally and transversely spaced miscellaneous items 6, 7, educated symmetric bending of the flexible strips of thick fabric and machine stitch sewn to the base 3 along the sides of the panels 1. These miscellaneous items 6, 7 have cavities (channels) with installed perforated straps 8, which provides rigidity edges of the panels 1. Thus, the mounting of each photovoltaic panel 1 advanced through four perforated strips 8, built-in cavities (channels) longitudinally and transversely spaced overhead elements 6, 7 of the frame 4 along the sides of the PV panels 1.

In the assembled solar panel longitudinal and transverse overhead elements 6, 7 are located over the respective edges of the front surface of the photovoltaic panel 1 so that the frame 4 has a width of 2-3 cm. The frame 4, the perforated strips 8, photovoltaic panels 1 are provided with suitable openings for the installation of fastening elements in the form of screws 9 (Fig 3). The presence in the frame 4 perforated slats 8 it provides a tight fit to the front surface of the photovoltaic panel 1, which protects the ends of photovoltaic pan is lei 1 from the adverse effects, including from dust, moisture.

To avoid distortions, ensuring the flatness of the working surface of the solar photovoltaic panel 1 is connected to the frame 4 by screws 9, are located, in particular, with the same step symmetrically with respect to the bend 3 of the solar battery (folded). Example of connection of the photovoltaic panel 1 with the frame 4 and the base 3 by means of screws 9 are shown in figure 4. When this connection is folded (figure 5) distance between outer surfaces of adjacent photovoltaic panels 1 not less than 3 millimeters, which provides protection from abrasion, mechanical damage during repeated folding solar panels.

Framework 3 installed in the frame 4 by the PV panels 1 in idle state is reached in a bundle of type "bag" (or "portfolio"). In Fig. 5, the system is composed of zigzag (accordion) in a bundle with the base 3 of a flexible fabric material. While photovoltaic panels 1 are face to each other and secured in folded position by means of locks-latches 10. In this form the solar battery ready for transportation at any distance, for convenience, a handle 11.

For ease of folding solar battery contains an even number (two to ten) of the PV panel is 1. Depending on the required output power and voltage, the number of photovoltaic panels 1 and their connections may be different. A variant of the solar battery of four photovoltaic panels 1 in expanded form presented in figure 1. Photovoltaic panels 1 are interconnected in a system of conductors 12, placed in the top 13 (binder) 3 along the long side of the solar battery. Mount photovoltaic panels 1 to the base 3 and the conductors 12 connecting the photovoltaic panel 1 in the system shown in figure 2.

Combining the location and connection of conductors (12), can be obtained at the output of the solar battery voltage and current multiples of the nominal values of current and voltage of individual photovoltaic panel 1. Output cable ends 14 connector 15.

A solar battery as follows.

For unfolding solar panels into position need to undo the locks 10 and stretch zigzag folded photovoltaic panels 1 to their working flat. While photovoltaic panels 1 are moved apart "accordion" and in the extreme extended position of the photoactive area of the battery is equal to the sum of the photoactive areas of individual photovoltaic panels 1. The electricity consumers of the data is conducted to the connector 15.

Operation of the solar battery is as follows. Expanding the battery working surface of the Sun, connect it to the consumer (load), observing the polarity (not shown). Solar panel folding can be stored and operated at a temperature from minus 20°C to 40°C. its Main purpose is to charge and the battery recharging household equipment (laptops, portable TVs, radios, etc. in the field. So it can be fitted with a compact charger controller to batteries with a nominal voltage of 6 V, 12 V or 24 Century, the Process of bringing solar into the transport position is carried out in reverse order.
