AI Technical Summary

Technical Problem

Foreign objects blocking the surface of photovoltaic panels can reduce power generation efficiency and may cause scratches. Existing anti-covering measures can also damage photovoltaic panels due to the impact force of foreign objects sliding down.

Method used

A highly elastic and wear-resistant transparent film is set on the surface of the photovoltaic panel. The film is expanded by a power mechanism and the photovoltaic panel is deflected to a vertical position to isolate foreign objects and make them slide off. The expansion force of the film weakens the adhesion and impact force of foreign objects.

Benefits of technology

It effectively protects photovoltaic panels, prevents scratches from foreign objects, improves power generation efficiency, promotes the removal of foreign objects, and extends the service life of photovoltaic panels.

Abstract

This invention relates to the field of photovoltaic power generation technology, specifically an integrated photovoltaic power generation device and system with anti-coverage feature. It includes a base, and further includes: an assembly frame hinged to the base at one end, with two sets of support mechanisms symmetrically arranged on the base at the other end of the assembly frame, and a photovoltaic panel mounted on the assembly frame. The two sets of support mechanisms can drive the assembly frame to deflect, thereby changing the tilt angle of the photovoltaic panel; a thin film adhered to the surface of the photovoltaic panel, with a frame body fixed to the assembly frame to seal and press the edges of the thin film; a power mechanism connected to a pressurizing mechanism, which can expand the thin film. The thin film provides sufficient protection for the photovoltaic panel, thus effectively eliminating the pressure and friction between the film and foreign objects during their slippage. When foreign objects slip, they interact with the expanded film instead of acting on the photovoltaic panel, improving the protective effect and helping to maintain the power generation efficiency of the photovoltaic panel.
