Quality connects the world---The QC Solar is a leader in the manufacturing and marketing of solar PV electronic devices, junction box, sockets and connectors. We have 2 factories in China, which are located in Suzhou City, and in Huai’an city. QC Solar has got the certifi-
cations of ISO9001, ISO14001, OHSAS18001, and its products have been both approved by TUV&UL. The company is engaged in the design and manufacture of products related to all PV applications. It is applied into green energy industry, and is committed to using inter-
nationally advanced techniques in the maintenance of its quick-connect applications, as well as incorporating practicable solutions for customers all over the world.
QC Solar cooperates with the well-known Xi’an Jiaotong(Liverpool) University to make the research of solar control system, the develop-
ment of the products and their marketing applications. The products include solar junction box, off-grid solar charge controller, smart PV power return system, solar cable, connectors, branched cable, multi-function terminal and controllers. Originality features highly in our products and thanks our investment in sound quality, our products work well in harsh outdoor environment for long-term application. Moreover, our PV connecting system have been proved to be able to output large currents, secure a more reliable connection and give excellent insulation and weather-proof performance. All of this greatly improves the security and reliability of our solar module and power station.
We have two well equipped factories, which have 48 imported, fully automatic, program controlled molding machines,17 assembling lines, one mold workshop, as well as a lab for the quality of the products, and the bility, to develop the mold, inject, weld, assemble and test.
The engineers of QC Solar come from a variety of industries, all with electronics, plastic, machine and PV background. They have rich experiences in designing and innovating. They can accomplish design ideas according to international standards and individual orders.
Our excellent quality products can be attributed to QC Solar’s creative design, advanced manufacture systems and excelsior staff. Applying up-to-date manufacturing techniques, on the spot management, quality control logos and higher inspection equipment, we keep innovating and progressing.
