Technical Field

[0002] Photovoltaic thermal energy storage has now become one of the main ways of light energy conversion, effectively realizing the use of clean energy. In the prior art, there are many documents related to photovoltaic thermal energy storage devices, such as Chinese patent CN217486434U, which mainly ensures the support stability of the beam by setting a connecting seat at the top of the bracket, and sets a connecting part at the end of the beam to achieve installation and fixation with the connecting rod. The connecting rod ensures the support stability of the photovoltaic panel, and a clamping arm is set on the connecting rod to achieve clamping and fixation of the photovoltaic panel. Thus, the device can stably achieve the installation and clamping of the photovoltaic panel to prevent the photovoltaic panel from shaking or shifting during the rotation adjustment process, thereby ensuring the working stability of the photovoltaic panel and effectively realizing photovoltaic thermal energy storage. Such issues all involve the stability of photovoltaic panels and the effective realization of photovoltaic thermal energy storage. However, when photovoltaic panels are placed for a long time, more impurities such as leaves and dust will often accumulate on the surface of the photovoltaic panels. The accumulation of these impurities will reduce the exposed area of ​​the photovoltaic panel surface and reduce the efficiency of light energy conversion. Utility Model Content
