Embodiment Construction

[0026] At present, the general fire rating of conventional components is Class C, that is, the flame temperature of the component test is 760±28°C, the wind speed is 5.4±0.2m / s, and the flame spread distance is less than 3.9m. This fire rating is currently unable to meet the fire protection requirements of foreign roof power stations. At present, the U.S. market requires that the fire protection level of modules must reach Class A, and that photovoltaic modules are required to withstand direct combustion of gas flames for more than 10 minutes without spontaneous combustion. The test flame temperature is 760±28°C, and the wind speed is 5.4±0.2m / s. The flame spread is less than 1.82 meters from the component. Therefore, the improvement of the fire rating of components is the trend and direction of component development in the future.

[0027] Aiming at the deficiencies of the prior art, the present invention provides a solar photovoltaic cell assembly, which replaces the tradit...

Abstract

The invention discloses a solar photovoltaic cell module. Traditional tempered glass is substituted by photovoltaic tempered glass with fireproof grade A so as to meet the standard of the fireproof grade A; a fireproof intelligent junction box with a relative thermal index of 120 is adopted and has a relatively good fireproof function, moreover, a control module having a function of switching off and a detection module having functions of over / under-voltage detection and over-temperature detection are arranged in the junction box, so that the functions of over-temperature and over / under-voltage detection, controllable switch-off and the like are achieved, and the safety of the module during the running process is further ensured; and further, a cable of the junction box adopts a standard flame-retardant corrugated metal pipe (CMP) of UL, and the fireproof performance is further improved. The module disclosed by the invention can be completely implemented in a traditional crystal silicon module production line, no extra process and labor are needed to be added to the production line, and the module is convent to produce.

Description

technical field [0001] The invention belongs to the technical field of crystalline silicon solar components, and in particular relates to a solar photovoltaic cell component. Background technique [0002] Solar energy is a clean and renewable new energy source, which is more and more favored by people and has a wide range of functions in people's life and work. One of them is to convert solar energy into electrical energy, and solar cells use solar energy to work. Its advantage is that it is not limited by factors such as region and altitude, and can convert a large amount of heat energy into electrical energy. [0003] In recent years, with the rapid growth of the number and scale of solar photovoltaic power plants around the world, various power plant fires caused by fires in photovoltaic power plant components are not uncommon. There have been more serious spontaneous combustion incidents of solar modules in Germany, the United States, Australia and other countries, espe...
