A Photovoltaic Panel Safety Detection and Life Evaluation System

Abstract

The invention discloses a photovoltaic panel safety detection and life evaluation system, which mainly comprises a photovoltaic panel, a temperature sensor, an ammeter, a voltmeter and a controller, wherein the number of the temperature sensor is at least one, the temperature sensor is arranged on the back surface of the photovoltaic panel, and is in contact and installed with a photoelectric conversion material; the ammeter and the voltmeter are installed on power supply output terminals of the photovoltaic panel separately; the temperature sensor, the ammeter and the voltmeter are connected with the controller separately; the controller continuously receives temperature signals of the temperature sensor, selects the highest temperature and compares the highest temperature with a fixed threshold value; and the controller continuously receives current and voltage signals of the ammeter and the voltmeter, and calculates output power of the photovoltaic panel. The photovoltaic panel safety detection and life evaluation system gives comprehensive consideration to operating temperature parameters, power generation power parameters and external environmental parameters of the photoelectric conversion material of the photovoltaic panel, so as to evaluate the operating life of the photovoltaic panel precisely and prompt the staff to replace it timely, facilitates the equipment maintenance of large-scale photovoltaic power plants, reduces maintenance cost, and ensures power generation efficiency.

Description

technical field [0001] The invention belongs to the technical field of solar power generation, and in particular relates to a photovoltaic panel safety detection and life evaluation system. Background technique [0002] Photovoltaic power generation is one of the scientific and technological means for human beings to utilize solar energy. Existing photovoltaic power generation panels are manufactured by integrating multiple pieces of photoelectric conversion materials on one substrate and finally assembling them on a support. In a large-scale photovoltaic power plant, a huge number of photovoltaic power generation panels are arranged in an array, connected to a booster and converter device through a series-parallel circuit to store electric energy in the battery or connected to the grid. [0003] As we all know, photovoltaic materials have a certain service life, and due to the complex manufacturing process, each photovoltaic power generation panel may have a different serv...
