Description
Technical Field
[0001] This utility model relates to the field of solar photovoltaic and photothermal integrated utilization technology, specifically to a photovoltaic structure and device with tilt angle adjustment and waste heat energy storage functions. Background Technology
[0002] Currently, with the increasing demand for clean energy, concentrated photovoltaic (CPV) power generation technology has become a key focus in the photovoltaic power generation field due to its ability to reduce the amount of photovoltaic cells used and lower costs. It is widely used in distributed photovoltaic power stations, industrial complementary power generation, and other scenarios. However, existing CPV power generation systems have at least the following significant drawbacks: First, the light-gathering method is limited. Reflective light-gathering (such as dish-type) has a low light-gathering ratio or poor stability, while refractive light-gathering has low light transmittance and uneven light intensity distribution, resulting in low overall energy utilization. Secondly, most solar tracking devices are traditional dual-axis structures with limited adjustment range, which reduces the concentration efficiency. Third, high-concentration solar cells generate a lot of heat. Existing heat dissipation mostly relies on silicone adhesive heat sinks, which have high thermal resistance and low efficiency. Excessive battery temperature not only reduces efficiency but may also damage devices. Moreover, most systems do not recover heat energy, resulting in serious energy waste and a comprehensive utilization rate of only 15%-20%.

Furthermore, the pitch motor push rod 22 can be used to achieve pitch drive orientation adjustment, thereby meeting the requirements of solar azimuth adjustment.
[0024] The planar reflector array 32 consists of several planar reflectors, which are respectively mounted on the side of the main frame 31 via universal joints 36. The reflective surfaces of the planar reflectors all face inward. A 2-4cm windproof gap is left between adjacent reflectors to reduce wind resistance. The reflected light can be precisely focused onto the Fresnel lens array 24 by adjusting the reflector angle.
[0025] The side of the main frame 31 is provided with a reflector cup 34 below the Fresnel lens array 33. The reflector cup 34 is respectively provided with the Fresnel lens array 33 and the photovoltaic cell module 4 to reflect the diverging light to the cell and improve the light concentration efficiency.
