Photovoltaic cell panel repairing device

Abstract

The invention relates to a photovoltaic cell panel repairing device, and the repairing device comprises a charging module, a power storage module and a repairing module. The charging module stores electric energy generated by the photovoltaic array into the power storage module; the power storage module supplies power to the repair module; a judgment module is arranged between the power storage module and the repair module, and after the judgment module meets specific conditions, the power storage module and the repair module form an electric path; the judgment module comprises a voltage detection module and a GPS time module, the voltage detection module detects the magnitude of voltage on the two sides of the photovoltaic array, and the GPS time module judges whether the location is at night; the specific condition is that the voltage of the two sides of the photovoltaic array is 0, and the GPS time module judges that the location is at night. According to the application, the accuracy of the photovoltaic cell panel in the dormant state when the repairing device is used for repairing the photovoltaic cell panel is improved, and the damage of the photovoltaic cell panel caused by repairing the working photovoltaic cell panel by the PID repairing device is avoided.

Description

technical field [0001] The present application relates to the technical field of photovoltaic battery panel repair, and in particular to a photovoltaic battery panel repairer. Background technique [0002] The PID (Potential Induced Degradation) effect, also known as potential-induced degradation, is a phenomenon in which the output characteristics of certain types of photovoltaic panels are attenuated due to potential induction, which will lead to a decrease in the output power of the photovoltaic system. Studies have shown that the PID effect is reversible for most photovoltaic panels, that is, by applying a voltage of the opposite polarity that causes attenuation, the attenuation characteristics can be restored or slowed down, so it is necessary to prevent or repair PID through anti-PID technology. [0003] The existing anti-PID technology at night is an off-line anti-PID technology. Its PID repair device is generally installed on the positive pole (or negative pole) of t...

Problems solved by technology

[0004] Regarding the related technologies mentioned above, the inventor believes that there are the following defects: when the PID repair device is in use, it needs to be connected to a separate power source. However, since the photovoltaic panels are installed in a higher open area, it is difficult to introduce power, resulting in Inconvenient; and because the PID repair device can only perform PID repair on the photovoltaic panel at night, but the light time will change every day, if the PID repair device does not judge whether the light is on or not, it is easy to cause irreversible damage to the panel
