Description

Technical Field

[0001] The present invention relates to the field of photovoltaic technology, and in particular to a photovoltaic device and component performance improvement system. Background Art

[0002] At present, relatively simple monitoring and control methods are usually used to improve the performance of photovoltaic equipment components. Generally, only some environmental factors are monitored by a single sensor, such as only monitoring temperature or light intensity. In terms of control, it is only roughly adjusted based on simple thresholds. For example, when the temperature exceeds a certain value, the temperature is reduced, but the cooling or heating method may be relatively simple and the effect is limited. For the adjustment of light intensity, only a fixed shading device may be used, and it is impossible to flexibly adjust according to the actual light conditions. For the control of humidity, there may be a lack of effective monitoring and processing methods. In terms of performance monitoring and evaluation, it may only be a simple voltage and current monitoring, which cannot fully evaluate the performance of components. In addition, the system may lack data recording and analysis functions, making it difficult to optimize and improve according to actual operating conditions. Maintenance work may also not be regular and systematic enough, resulting in the stability and reliability of the equipment being affected. At the same time, the existing technology may not have the functions of remote monitoring and adaptive adjustment, which limits the convenience and versatility of its management.

[0003] However, the existing technical solutions still have some shortcomings and need to be improved. First, only some environmental factors are monitored, and the working environment of components cannot be fully understood. Rough adjustment based on simple thresholds cannot accurately control environmental factors, which affects the performance improvement of components. Light adjustment is limited, and fixed shading devices cannot flexibly adapt to light changes, which may lead to low energy efficiency. Insufficient humidity control and lack of effective humidity monitoring and processing methods may affect the normal operation of components.

[0004] Incomplete performance evaluation Simple voltage and current monitoring cannot fully evaluate the performance of components and it is difficult to find potential problems. Without data recording and analysis functions, it is difficult to optimize and improve the system. The lack of remote monitoring function limits the convenience and timeliness of management. It cannot be adaptively adjusted according to different types of components and working environments, and the scope of application is limited. Therefore, we make improvements to this and propose a photovoltaic equipment and component performance improvement system. Summary of the invention
