Solar photovoltaic connectors need to have high current transmission capacity, and generally use low resistance, high conductivity materials and structure design to reduce energy loss and heat generation. To enable interchangeability and interoperability of photovoltaic systems, solar photovoltaic connectors usually follow specific industry standards.

In photovoltaic systems, the lower the resistance of the connector, the better, because lower resistance will reduce energy loss and heat generation, improving the efficiency and performance of the system. Here are some key points related to connector resistance:
Maximum power point loss：
The photovoltaic module has a Maximum PowerPoint (MPP) under different lighting conditions, outside which it provides the maximum output power. If the resistance of the connector is high, an additional voltage drop will be generated when the current flows through the connector, resulting in the loss of the maximum power point and reducing the overall efficiency of the photovoltaic system.
System heat loss：
The resistance of the connector will cause electrical energy to be converted into heat energy, causing energy loss. Higher connector resistance generates more heat, which can cause the connector to overheat and reduce the performance and reliability of the system.
Systematic thermal diffusion：
Connectors with high resistance may cause thermal diffusion problems. When the current passes through the high-resistance connector, the connector itself will heat up, and due to the presence of the current, the heat will spread around the connector. This can cause other components or materials in contact with the connector to become heated, further affecting the reliability of the system.
Overheating and damaging wind：
High voltage connectors are prone to overheating when they run under high load for a long time, which may cause connector damage or electrical fire.

Therefore, lower connector solar is beneficial for photovoltaic systems, which can reduce maximum power point loss, reduce energy loss and heat generation, and improve system efficiency and performance. Therefore, when selecting connectors, you should choose connectors with low resistance and ensure that the connector material and design have good electrical conductivity to minimize energy loss and system heat loss.
