AI Technical Summary

Technical Problem

After long-term use of photovoltaic panels in areas with abundant sunlight, they are easily affected by rainwater or dew, causing water droplets to adhere to the surface of photovoltaic panels, reducing the intensity of sunlight, and reducing the photovoltaic panel's light energy absorption efficiency and power generation efficiency.

Method used

A water removal device for photovoltaic power generation is designed, including a fixing frame and a wiper assembly arranged on the photovoltaic panel or its bracket. The wiper assembly is composed of a wiper rod and an elongated rod driven by a motor. The wiper rod is equipped with a chute and a bristle, and the elongated rod can be adjusted in length to accommodate photovoltaic panels of different sizes.

Benefits of technology

The front of the photovoltaic panel is cleaned by driving the wiper rod and the extension rod by the motor, effectively removing rainwater or dew, improving the power generation efficiency of the photovoltaic panel. Due to the design of the extension rod and locking unit, it has good adaptability and can be adjusted according to the size of the photovoltaic panel.
