Full Advanced Automated Production

01.

Solar cell Welding

Use automatic welding machine to connect solar cells in series.
All the solar cells are made by top class brand, like TW Solar, Longi Solar

02.

Automatic typesetting machine

After setting up the program according to the requirements of the process drawings, the typesetting machine will automatically typeset the battery string. High precision, high efficiency, low defect rate

03.

Automatic welding

Automatic laying of EVA, backing, automatic cutting of excess backing material
100% automation of the entire production process

04.

Visual Inspection

Through the turning machine, completely inspect the solar panel after lamination, and record the defects and feedback to the previous process

05.

EL Testing

Use the mirror to inspect the appearance of the solar modules before lamination, and repair them if they are defective;

06.

Flash Testing

Including temperature, power, voltage, current and other related tests, ensure 0~+5W Positive Power Tolerance

FAQ

Why should we buy from you not from other suppliers?

Our team have 10 years exprience in solar products,selling to 50 countries,we are
experienced in international business;we know suitable price and on time delivery are two key
points;we supply good service rather than other factories.

Can we Visit factory?

Surely,our head office is in Wuxi City.One hour to Shanghai.It is very convinent.

Are we Manufacturer?

Yes,we have own factory in wuxi city and Nanjing city.And we also have sub contract with
other factories.
