How to Choose the Right Stringer Machine?
First, compatibility: it must handle 182mm and 210mm cells with quick changeover. Second, breakage rate and soldering yield, test with your own cells to see real performance. Third, stability and service: the machine should run reliably for long shifts, with fast support when needed. Also check if the stringer machine can be upgraded later for half‑cut, multi‑busbar, or heterojunction processes.
Is BC technology the Future?
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.
How to Calculate Annual Energy Production From Solar Panels?
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.
What is the Solar Panel Manufacturing Process?
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.
