Quality Control

Supply

System

1. Solar cell: Dark color, black, no color difference

2. Solar Cell shape: corner piece

3. Solar cell efficiency: 21%

Production

System

1. Classification of solar cell with different colors, powers and efficiencies using automatic sorting equipment

2. EL test of the solar cell by EL device to ensure that the solar cell is not cracked

3. Components are fully automated production line operations

1. EL tester tests the solar cell to ensure no cracks

2. The component tester performs EL and data testing before component packaging to ensure data is acceptable and components are not cracked. 

3. Component products are monitored with data from a tester to ensure data is correct

Packaging

System

1. Can be packed in carton box or wooden cases

2. The solar panel is in an upright packaging mode to reduce the transport breakage rate

Supply

System

1. Battery case, ABS material conforming to UL94HB and UL94V-0 standards, no color difference, no crack.

2. The unique lead-calcium grid improves the hydrogen evolution potential, reduces gas evolution, reduces corrosion rate, and extends battery life.

3. The use of copper terminals, excellent conductivity and high wear resistance, enhances high current discharge performance;

4. High quality AGM partition for partition

Production

System

1. Battery plate production workshop, independent production of positive and negative plates, effectively ensuring the quality of the plates

2. Semi-automatic cladding machine): Semi-automatic double-layer cladding technology, double-layer separator can better prevent short circuit of the pole plate. The semi-automatic double-layer board process ensures that the packaged groups are neat, beautiful and clean.

3. Automatic slotting machine: higher efficiency, saving the process involved in manual slotting, avoiding the human contact group, maximizing the protection of the pole group, making the battery have very good self-discharge performance, battery consistency, total Voltage consistency.

1. DC spectrometer: high precision detection of lead purity to ensure purity above 99.994%

2. High current detector: ensure that each battery is under high current, whether charge and discharge normal

3. Large battery tester: Under high current, whether the bus bar of the battery has a problem of melting and short circuit

4. Internal resistance meter: Make sure that the internal resistance and voltage of each battery are normal, and the consistency of the battery.
