[0002] With the continuous acceleration of scientific and technological development, energy has become a bottleneck restricting the development of science and technology. Traditional non-renewable energy sources such as oil and coal have limited reserves, and people are paying more and more attention to renewable energy sources such as wind power, hydropower, and solar energy. As a renewable and clean energy, solar energy plays an important role in the development of new energy technologies. From large solar thermal power stations using collector towers and heliostats to solar panels installed on street lamp poles, it has been widely used in all corners of society. However, existing solar panels are heavy and cannot be bent, making them inconvenient to move, resulting in the problem of inconvenience in carrying. In addition, solar panels are usually laid directly on the ground when used in the wild, making them extremely susceptible to the influence of ground humidity, shortening the service life of solar panels.

[0028] The back of the shell is provided with an adjustment component for driving it to adjust the light receiving angle, the adjustment component includes a stand 4, a light intensity sensor is provided on the top of the stand 4, the light intensity sensor is set in the same direction as the solar cell panel 1, the side surface of the stand 4 is rotatably connected with a driving gear 5, the back of the driving gear 5 is connected with a micro motor, the micro motor is electrically connected to the light intensity sensor, the middle of the driving gear 5 is connected with a rotating wheel 7 via a connecting shaft 6, the rotating wheel 7 is connected to the connecting shaft 6 at a wheel surface away from the center of the circle, the outer periphery of the rotating wheel 7 is provided with a connecting arm 8 extending outwards, the connecting The other end of the arm 8 is connected to the upper part of the linkage rod 9. The top of the linkage rod 9 is inserted into the back of the shell and connected to the shell. The bottom of the linkage rod 9 is connected to the adjusting arm 10. A waist-shaped groove 11 is provided on the surface of the adjusting arm 10. A driven shaft 12 is slidably connected in the waist-shaped groove 11 to drive the adjusting arm 10 to rotate up and down. The driven shaft 12 is fixed to the wheel surface of the driven gear 13, and it deviates from the center of the driven gear 13. The center of the driven gear 13 is connected to the stand 4 via a fixed axis. The teeth of the driven gear 13 are meshed with the teeth of the driving gear 5. The other end of the adjusting arm 10 is hinged to the stand 4.

[0029] The width of the ETFE backboard 105 is 2-3 cm greater than the width of the ETFE panel 101. The ETFE backboard is extended by 2-3 cm so that it is melted by heat and then bonded to the hemming.

[0030] The first shell 2 and the second shell 3 are connected as a whole through canvas in the middle, and the side of the first shell 2 and the side of the second shell 3 are both provided with a buckled handle 14. The solar cell panel 1 is easy to grab by providing the handle 14.

[0031] The back of the first shell 2 and the second shell 3 are both sewn with a support plate 15, and the inner wall at the bottom of the support plate 15 is provided with a Velcro sub-strip 16, which is bonded to a Velcro mother patch 17 placed on the surface of the first shell 2 or the second shell 3.
