Advantages of N-Type TOPCon Bifacial Panels

Higher Efficiency: 22–24%+ module efficiency due to reduced recombination.
Lower Degradation: <0.5% annual degradation vs. ~0.7% for PERC.
Better Temperature Coefficient: Performs better in hot climates.
Longer Lifespan: 30+ years with minimal LID (Light-Induced Degradation).
Bifacial Gain: Extra energy from rear-side illumination.

Smart Manufacturing

Solar Cell String EL Test

For string testing, EL imaging provides valuable insights into the electrical and structural integrity of interconnected solar cells.

 

EL Testting before Lamination

The EL (Electroluminescence) test is a crucial quality control and diagnostic tool used in photovoltaic module manufacturing and field inspection.

Current-Voltage Curve Test

The I-V curve test (Current-Voltage curve test) is a fundamental procedure used to evaluate the performance of a solar module or panel. It measures the relationship between the current (I) and voltage (V) under controlled conditions to determine key electrical parameters.

Insulation withstand Voltage Test 

The insulation withstand voltage test (also known as a dielectric strength test or hipot test) used to ensures that the insulation can withstand high voltages without breaking down, preventing electrical hazards such as short circuits or electric shocks.

EL Test

The EL (Electroluminescence) test is a crucial quality control and diagnostic tool used in photovoltaic module manufacturing and field inspection.

Solar Module Final Appearance Test

The Solar Module Final Appearance Test is a quality control inspection performed to ensure that the photovoltaic (PV) module meets visual and aesthetic standards before shipment or installation. This test checks for any visible defects that could affect performance, reliability, or customer satisfaction.
