5-50MW Manual / Semi Auto Solar Panel Production Line

Whilst we offer some of the most competitive pricing in the industry, we firmly believe that a well-designed production line holds far greater value than the mere pursuit of low cost. A single quotation cannot suit all. Only after gathering the necessary information and undertaking a bespoke design tailored to each product's characteristics and process requirements can we provide a quotation truly worthy of discussion.

Cells are loaded by an automatic loader. For half‑cut or third‑cut, cells go through a laser scribing machine for precise splitting. The cells are then fed into a stringer, where ribbons are soldered to form cell strings. After stringing, a bussing machine interconnects the strings, followed by layup, lamination, framing, junction box attachment, and final testing (EL and flash test). The stringer machine and laser scribing machine are the most critical pieces, they determine breakage rate and soldering quality.

Simply multiply the total panel power (in kW) by the annual peak sun hours in your location, then apply a system efficiency factor, typically around 80%, to get a rough estimate. But from a manufacturing equipment perspective, what matters just as much is ensuring that processes like stringing and lamination don’t introduce micro‑cracks or poor soldering, because those issues will directly reduce the panel’s actual output.

BC (Back Contact) technology is undoubtedly a key direction for next-generation high-efficiency PV modules. Its busbar-free front side offers not only superior aesthetics but also significantly reduces shading, leading to higher light absorption and increased power output. Rather than simply declaring BC as the only future,In fact, BC is a platform technology that can be combined with techniques such as Topcon HJT and perovskite tandem cells to squeeze out the last drop of efficiency gains.

Therefore, we believe BC technology will remain at the forefront of the upcoming technological transformation, making now the opportune moment to invest in BC.
