PV Tech and Tongwei Solar are co-hosting a webinar exploring the company’s shingled modules and the advantages they bring to projects. To register for the webinar, which takes place at 3:00 PM (BST) on 18 October, please click here.

Product Outline:

Tongwei Solar’s shingled modules, built on 210 cells, are based on the company’s innovative patented shingled technology, forming flexible interconnects and a unique internal circuitry, enabling higher efficiencies and better power generation performance. The maximum power of a single module can now reach 670W and efficiency has been enhanced to 21.6%.

  1. With the rapid development of renewable energy sources around the world, land resources available for projects are becoming increasingly scarce. This requires PV systems to maximise power generation and efficiency in order to achieve maximum return on investment from each project.
  2. During module operation, the risk of hot-spots not only affects power output, but also causes safety risks, potentially reducing module durability.
  3. The solder ribbons inside the modules contain lead, which can cause environmental pollution.


  1. In comparison to other module BOS costs, Tongwei’s shingled modules feature higher power. Their utilisation of bracket, pipe pile and cabling is higher, resulting in a reduction in construction cost per watt of a power station and, logically, lower levels of investment.
  2. Compared to conventional modules, shingled modules involve a cell cut into strips. The technology results in both string current within the module and the risk of hot-spots being lower.
  3. Shingled modules use shingled bonding technology instead of connection via solder ribbons, so lead content is also significantly reduced.  Testing has shown that Tongwei’s shingled modules are resistant to extreme weather conditions and perform better under shading, resulting in extended working life and service condition.

Application: Household, commercial and industrial and centralised systems.

Availability: Currently available.

PV Tech has been running an annual PV CellTech Conference since 2016. PV CellTech USA, on 8-9 October 2024 is our second PV CellTech conference dedicated to the U.S. manufacturing sector. The event in 2023 was a sell out success and 2024 will once again gather the key stakeholders from PV manufacturing, equipment/materials, policy-making and strategy, capital equipment investment and all interested downstream channels and third-party entities. The goal is simple: to map out PV manufacturing in the U.S. out to 2030 and beyond.

Understanding PV module supply to the European market in 2025. PV ModuleTech Europe 2024 is a two-day conference that tackles these challenges directly, with an agenda that addresses all aspects of module supplier selection; product availability, technology offerings, traceability of supply-chain, factory auditing, module testing and reliability, and company bankability.
