Problems solved by technology

However, it is greatly affected by the change of the incident angle of sunlight, and the elevation angle of the concentrator needs to be adjusted with the seasons; the concentration ratio is not optimized to the best effect, and the light received per unit area is small; At the bottom, the spot focus is irregular in shape, which may cause a local short circuit of the solar panel due to uneven illumination, which will affect the power generation effect
In addition, this patent does not explain how to optimize the combination of solar panels to improve the power generation efficiency of solar cells

Embodiment Construction

[0014] The specific structure of the present invention will be described in detail according to Fig. 1 and the embodiment. The power generation panel includes a face shield 2, a light concentrating reflector 4, a solar cell panel 3 and the like. Wherein the frame 1 should be processed by aluminum alloy profile with anti-corrosion protection layer. The mask 2 is made of commonly used sheet materials with nanometer self-cleaning, low reflection, transparent, anti-riot protection functions. The solar battery panel 3 can be made of monocrystalline silicon or gallium arsenide. The concentrating reflector 4 is composed of a matrix 9 and a reflective film 10 whose section is a compound parabolic smooth concave surface. The solar cell panel 3 is sealed at the bottom opening of the base body 9 of the concentrating reflector 4 . Each concentrating reflector 4 of array distribution is closely arranged in the frame 1, and the solar cell panel 3 at the bottom of the substrate 9 of each ...

Abstract

The invention includes frame, face shield assembled inside the frame, condensation reflector and solar panels. The technical key points are: the condensation reflector is composed of basal body of smoothing concave curved surface with section in shape of composite parabola and reflective thin film; solar panels are sealed at jaw opening at bottom of basal body; array distributed each condensation reflector is arranged in the frame closely; through lead wire and inverter, each solar panel is connected to controller and power supply system. Features are: reasonable structural design, no need of sun tracker, increased generating capacity of solar battery per unit area, flexible and reliable assembly, and panel shape close to specification of current sheet material. Being possible popularized in large area in low cost, the invention is in favor of environmental protection and energy saving.

Description

technical field [0001] The invention relates to a solar concentrated power generator, in particular to a composite parabolic reflective concentrated solar power generation panel composed of several parabolic reflectors. It can form a solar cell module array or be designed as a small to large solar power supply system. Background technique [0002] At present, the world's photovoltaic power generation industry is developing at an average annual rate of about 28%, which is one of the fastest growing industries in the world. Among the various solar cells available in the prior art, although amorphous silicon solar cells using glass or plastic substrates are the cheapest, their efficiency is only about 6%; It can be as high as 30%, but the cost is 100 times that of the former; thin-film solar cells have the disadvantages of unstable technology and attenuation of power generation efficiency, and the battery life is short; monocrystalline silicon and polycrystalline silicon solar...
