AI Technical Summary

Problems solved by technology

Although photovoltaic power generation technology has been widely used, photovoltaic panels are not only not ideal in power generation efficiency but also underutilized, and insufficient light is one of the important reasons

In view of this, a photovoltaic panel array with a solar tracking structure has emerged, such as the "full-automatic solar dual-axis tracking device and control system" published in patent application No. 201510335502.4. This structure effectively improves the utilization rate of photovoltaic panels, but The structure and its control system are often complicated, which makes it difficult to reduce the cost. Therefore, its comprehensive performance has no obvious advantages

In addition, with the emergence of hot wind power generation technology, research on solar hot wind power generation technology has also been carried out, but domestic related research started relatively late, and there are not many related documents. The "Solar hot wind power generation device" and 201210358926.9 patent "a solar thermal wind power generation system combined with phase change heat storage technology" all involved in this technical field, the former focuses on a wind thermal power generation device that uses solar energy to heat the wind speed and uses a speed booster tube to increase the wind speed to generate electricity , the latter focuses on introducing a wind-thermal power generation system that combines phase-change heat storage technology to extend the power generation time. Both of them only conduct research on hot wind power generation technology

At present, research on the combination of photovoltaic power generation and solar thermal wind power generation is rare, and only two related patents can be found, including the utility model patent "Solar thermal wind power generation system combined with photovoltaic technology" published with application number 201120373134.X " and the invention patent with the application number 200810034261.X "Solar hot wind power generation system combined with photovoltaic technology", the descriptions of the two are basically the same, mainly focusing on hot wind power generation technology, and adding photovoltaic panels to the heat collector of the solar hot wind power generation system As a supplement to hot wind power generation, so as to improve power generation efficiency, but in essence, such a combination not only does not promote the efficiency of any independent power generation system, but affects and weakens each other
