2)Simple, quick and safe installation
3)IP65:the innovative sealing design, dust-proof and water-proof
4)Strong current and high voltage load capacity
5)Excellent material which meets UL94-V0 fire safety standard for long term outdoor application which it's outstanding and anti-ageing, waterproof and UV-resistance propeties

5.MC4 Connector

1)Highly robustness, UV-Resistance
2)Connector adopts touch and insertion of reed with inner-knob type
3)Auto-lock equipment of male and female points enable connection more easy and reliable
4)Popular figure suits most of field installation
5)Accommodates PV cable with deferent insulation diameters
6)The maximal working current will be changed when fixed with different types of diode

Production Line

Standard Automatic Production Line

At HETECH Solar, we scour the globe in search of the most suprior materials the industry has to offer. Combined with our near fully automated manufacturing system, we offer consistently high power modules that will last a lifetime. Each material has been carefully tested to meet our best in class standards.

1.Solar cell test

New technology and most superior materials offered. combined with our automated and semi-automated manufacturing and testing system, make sure Solar cell modules high efficiency. 


String creation by interconnecting the single photovoltaic cells, then interconnection of the strings in order to create an electrical circuit.

3.Lamination layer

Automatic pick up, rotation and positioning of the strings welding to the glass with high quality encapsulant material.

4.EL Test

EL test is able to highlight information that normally is not detectable with visual inspection, power measurement or IR testing, it is possible to identify micro cracks, degradation and shunted area on cells.


During this process, the encapsulant material cures and the muti-layer sandwich becomes one unit.

6.Trimming and Framing

Removals of surplus material along the sides, then install the aluminum frame around the module.

7.Power test & IV.

I-V curve acquisition in STC condition for the measurement of the peak power. It is to make sure all our finished solar panels could be used with high efficiency before delivery.

8. Package & Delivery

Environment-friendly and strong packing materials are used to protect the products from damage and ensure that the customers receive the goods in good condition without any damage , and the reasonable and professional packaging method is convenient to load and upload during transporting and save transportation costs.
