The quality inspection of pv busbar is an important part to ensure that its quality and performance meet the standard requirements, after all, good quality is the key to ensure the quality of the whole photovoltaic module, so how to test the quality of pv busbar? How can we see if the pv busbar is good or not?
Appearance check: check whether the appearance of the pv busbar is complete, without obvious damage or deformation. At the same time, it is also necessary to check whether the connectors and wire joints are firm and free of looseness.
Conductivity test: Use the conductivity test instrument to measure the resistance and conductivity of the pv busbar. The resistance value should be in accordance with the specified range to ensure low-loss transmission of electrical energy.
Current equalization test: connect multiple panels, through the pv busbar to centralize the convergence of power, measuring the output current of each panel is balanced. Current balance is very important for the efficiency and stability of PV power generation system.
Voltage withstand test: By applying a certain voltage to the pv busbar, test whether it can work normally and not have breakdown or leakage under the specified voltage.
Overcurrent protection device test: detect whether the overcurrent protection device configured for pv busbar works normally. You can simulate the overcurrent situation and observe whether the protection device can cut off the circuit in time.
Temperature and thermal stability test: place the pv busbar at a certain temperature, observe whether it works normally, and measure its temperature change. This test can verify the heat dissipation design and high temperature resistance of pv busbar.
Protection level test: According to the design and specifications of the pv busbar, the protection level test is conducted. Common tests include protection level IP65 or IP67, etc. to verify its dustproof and waterproof performance.
Durability test: The durability of pv busbar under different environmental conditions is tested through long time working simulation. The test includes the performance and reliability under high temperature, low temperature, humidity, vibration and other conditions.
The above are some common quality testing items of pv busbar, of course, if different manufacturers and different products may have other specific testing requirements, only through the comprehensive testing of pv busbar, to ensure that its quality and performance to meet the requirements to improve the reliability and durability of the photovoltaic power generation system. Rui creation for the industry’s leading enterprises in the production of busbar, the production of the busbar quality is guaranteed, have the intention to cooperate can contact us directly.
