The debate over the path and model of photovoltaics becoming the world's largest market in the past decade has never stopped

From 2006 to 2015, photovoltaics in China underwent a transformation from a laboratory to a production line, and with a total industry output value of 200 billion yuan, an average profit margin of 4.7%, and a cumulative installed capacity of 43.18 million kilowatts, it has become the world's largest market.

Photovoltaic companies cannot take the old path to enter overseas markets

In the context of slowing down the construction of the domestic photovoltaic market and continuous international trade frictions, Longi Green Energy Technology Co., Ltd., the world's largest monocrystalline silicon photovoltaic product manufacturing enterprise, has delivered a brilliant performance, with overseas sales accounting for 76% of the first half of this year, up from 12% in 2017. In the first half of this year, Longi Corporation's overseas sales of monocrystalline modules reached 2.423 gigawatts, a year-on-year increase of 252%. The company achieved a revenue of 14.111 billion yuan, a year-on-year increase of 41.09%, and a net profit attributable to shareholders of the listed company of 2.009 billion yuan, a year-on-year increase of 53.76%. The total assets were 51.615 billion yuan, a year-on-year increase of 30.15%, and it has continuously maintained its position as the world's highest valued photovoltaic enterprise.

Analysis of various indicators of photovoltaic connectors

The PV connector has the characteristics of fast and reliable connection, waterproof and dustproof, convenient use, and the shell has strong anti-aging and ultraviolet resistance; The connection of cables adopts compression and clamping methods, and the fixing of male and female heads is equipped with stable self-locking mechanisms, which can open and close freely. It is an indispensable and important component of solar power generation systems; The scientific structure of the product and carefully selected materials ensure that all mechanical and electrical properties are excellent.

Selection of Cable Design Methods in Photovoltaic Systems

1、 The selection of cables in photovoltaic systems mainly considers the following factors:

What is the protective performance of photovoltaic connectors?

The existence of photovoltaic connectors is mainly to protect components. When components in the array become hotspots due to obstacles such as dark clouds, branches, bird droppings, etc., the diodes in the components utilize their unidirectional conductivity to bypass problematic batteries and battery strings, thereby protecting the entire component and even the entire array, ensuring that it can maintain the necessary working state and reduce unnecessary losses.
