Everything Is Solar™ ETFE 18v 50W – 300W Flexible Solar Panel

1.Mono solar cell

1) Efficient PV conversion, stable performance
2)Unique etching process can increase the short-circuit current of the solar cell
3)Advanced PECVD technology provides well-proportioned navy blue silicon nitride anti-reflection velum
4)Screen printing patterns are accurate and smoothness of the electrode is improved thus making the cell easier for welding and laser cutting

2.Front Cover ETFE FILM

1)Increase conversion efficiency by 5%
2)Enhanced surface abrasion resistance
3)High anti-fouling
4) Easy to clean

3.Backsheet TPT

The back sheet of the module is a key package material applied to the module and is mainly composed of a weather-resistant fluorine material and a PET with excellent electrical insulation properties. The service life of such products is generally designed over 25 years, and the back film is the key to ensure such a long life. The solar module back film is located on the outer layer of the module, and the solar panel back film should have high electrical insulation, high weather resistance, high adhesiveness, and low water vapor transmission rate.

4.Junction box

1)With excellent resistance to high and low temperature, fire, aging and UV resistance, it can meet the long-term use requirements under harsh outdoor environmental conditions.
2) Excellent waterproof and dustproof effect, sealed by pouring glue.
3)Compact size, compact and practical structure, suitable for thin film photovoltaic modules, widely used.
4)The connection of the bus bar and the cable are respectively welded and crimped, and the electrical performance is safe and reliable.

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

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.

2.Welding

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.

5.Lamination

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.
