Problems solved by technology
[0004] The purpose of the present invention is to solve the shortcomings in the prior art, such as: but when these solar power generation devices are in use, they are easy to be caused by the natural sedimentation of dust in the air As a result, there is dust attached to the surface of the solar panel. Due to the blocking effect of the dust, the intensity of light received by the surface of the solar panel is inconsistent, and there is a large difference in the power generation efficiency of the local power generation components, which causes the hot spot effect, which in turn causes the solar panel to be damaged. damaged

Embodiment Construction
[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0028] refer to Figure 1-8 , a solar power generation device for solar street lamps that can prevent hot spot effects, including a concave curved concentrator 1, a flat lens 2 is fixedly connected to the concave curved concentrator 1, and a convex lens 3 is arranged inside the flat lens 2. There are two fixed tubes 4 symmetrically fixedly connected inside the curved surface condenser 1, and the two ends of the two fixed tubes 4 all pass through the concave curved surface condenser 1, and two solar panels 5 are fixedly connected between the two fixed tubes 4, two The solar cell panels 5 are stacked up and down, the upper solar cell panel 5 is above the optical focus ...

The invention discloses a solar power generation device for a solar street lamp capable of preventing a hot spot effect, and the device comprises a concave curved surface condenser, the concave curvedsurface condenser is fixedly connected with a plane lens, the plane lens is internally provided with a convex lens, and the concave curved surface condenser is internally and symmetrically fixedly connected with two fixed pipes. The two ends of the two fixing pipes penetrate through the inwards-concave curved surface collecting lens, and two solar cell panels are fixedly connected between the twofixing pipes. According to the invention, the illumination intensity difference caused by shading of dust attached to the planar lens can be effectively eliminated, so that the hot spot effect of thesolar cell panel is effectively prevented, and the power generation efficiency of the solar cell panel is improved by gathering sunlight to increase the light intensity; furthermore, power generationamount reduction caused by reduction of the use amount of the solar cell panels is compensated, and it is ensured that the power generation amount sufficiently meets use requirements.
Description
technical field [0001] The invention relates to the technical field of solar power generation, in particular to a solar power generation device for solar street lamps which can prevent the hot spot effect. Background technique [0002] A solar panel is a device that directly or indirectly converts solar radiation energy into electrical energy through the photoelectric effect or photochemical effect by absorbing sunlight. Solar energy is a green and non-polluting energy source. In response to the national call for energy conservation, emission reduction, and environmental protection, some existing street lights will be installed with some solar power generation devices to reduce the burden on the mains power supply. [0003] However, when these solar power generation devices are in use, it is easy to cause dust to adhere to the surface of the solar panel due to the natural sedimentation of dust in the air. Due to the blocking effect of the dust, the intensity of light receive...
