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.

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 and laser scribing machine are the most critical pieces, they determine breakage rate and soldering quality.

We consider after-sales service the beginning of a long-term partnership, not the end of a transaction. We provide a full-spectrum "service ecosystem" that covers the entire journey from initial discussion to stable mass production.

1.Collaboration and Delivery Process

Requirement Confirmation & Technical Discussion: We start with in-depth communication to clarify product specifications, capacity goals, and technical requirements, providing a preliminary technical solution.

2.Plan Finalization & Contract Signing: Upon reaching a technical consensus, we proceed to draft and sign the commercial contract and technical agreement.

3.Production Line Construction & Equipment Manufacturing: In parallel, you can proceed with plant construction/renovation, utility preparation, and team building. We simultaneously conduct lean manufacturing and assembly of the equipment.

4.Factory Acceptance Test (FAT): After assembly and debugging, we warmly welcome you to our facility for a pre-acceptance test to verify equipment performance firsthand.

5.Maritime Logistics & On-site Installation: Following FAT, equipment is shipped via maritime logistics to your plant. Our engineer team will be on-site to guide installation and positioning.

6.Commissioning & Site Acceptance (SAT): After installation, our engineers perform precise commissioning and complete the final Site Acceptance Test, ensuring the line meets all agreed performance metrics.

7.Training & Guided Production: We provide comprehensive operation and maintenance training, and guide you through small-batch trial production to ensure your team can operate the line independently.

8.Long-term Support & Continuous Improvement: Our comprehensive long-term after-sales service begins after mass production, including remote support, spare parts supply, periodic visits, and technical upgrade services, ensuring your sustained production and future growth.

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.

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.

A photovoltaic solar panel is a laminated assembly of five essential layers: the front is high-transmittance tempered glass, followed by an encapsulant layer (typically EVA or POE) that bonds and protects, then the solar cells which generate electricity, another encapsulant layer, and finally a backsheet that seals the rear surface. For bifacial modules, the backsheet is replaced with transparent glass or fluoropolymer film to capture energy from both sides. The entire stack is fused together under heat and vacuum in solar panel laminator—a critical stage in the pv panel manufacturing process, then framed with anodized aluminum and fitted with a junction box.

This is straightforward.

Firstly, we need to understand the type of modules you wish to manufacture: conventional or flexible, large-format or small-format, and whether any specialised processes are required. Secondly, we require details of your production line capacity requirements – be it a 50MW manual solar panel production line or a 2GW fully automated dark factory.

Finally, if you have already constructed a facility for your project, we need to know the dimensions of the building; a CAD file would be most helpful if available. Naturally, should you be unfamiliar with photovoltaic module manufacturing, there is no need for concern. We shall recommend the most suitable solar panel production line design based on your market requirements.
