Larger silicon cells, bigger PV modules, new BOS ecosystem

The solar industry is entering into a new era with the introduction of Large-Format Modules (LFM).  Like the efficiencies observed in the semi-conductor industry, a drive to larger wafer sizes (182mm and 210mm) by solar module manufacturers is resulting in larger, heavier, higher wattage and lower cost PV modules. 

Over the past decade, the solar industry has benefitted from a relatively standardized PV module. A whole balance of system (BOS) ecosystem of racking, DC collection systems, inverters and other components evolved to support these standardized PV modules. This major change to LFM architectures is now driving a complete revamp of the BOS ecosystem.  The current proposed large-format module architectures encompass a wide range of sizes (2.5 – 3.1 m2), open circuit voltages (40 – 50 Voc) and wattages (500W – 800W) as module manufacturers compete fiercely to define the new standard. The result is an uncertain BOS ecosystem that will need to remain flexible until a new standard can be defined. 

Fortunately, FTC Solar’s Voyager+ single axis tracker provides an optimized yet flexible design architecture to accommodate these LFM variants.  FTC Solar has and continues to work closely with top-tier module manufacturers to align product roadmaps and ensure our customers are receiving an optimized solution that maximizes the value opportunity associated with the adoption of LFMs. 

Higher Wattage Modules

More power per module means more power per tracker row.     


With fewer panels to install, labor costs for LFM projects are projected to be lower, leading to lower overall project costs.

BOS Ecosystem Savings

Fewer DC collections systems, supporting structures and foundations per watt are expected to contribute to project savings. 

Voyager+ solution for large-format modules

  • Same advantages of Voyager Plus More

    Voyager+ is built upon the standard Voyager design. That means that Voyager+ delivers all the advantages of the Voyager tracker plus the additional benefit of supporting LFMs.

  • Advanced Aeroelastic and Structural Design

    To accomodate Large-Format Modules, the standard Voyager system was re-evaluated, starting in the wind tunnel. New module rails, stronger torque tubes and a more powerful drive system are important features of the Voyager+ tracker.

  • Labor savings and More Power per Row

    Voyager+ allows for significantly more DC power per tracker row and is predicted to result in significant labor savings.

Large-format modules (LFM) have emerged as a key development in the innovation of solar module technology. Designing trackers that support LFM is crucial to the success of these next-generation solar power plants. As the adoption of LFM accelerates, the BOS ecosystem is being challenged to accommodate this rapid change to the solar module market.

In this webinar, learn how the shift towards large-format modules impacts tracker design. Experts from FTC Solar, LONGi Solar, and EPS will discuss how these changes to both module and tracker design result in lower LCOE solar power plants.

Join this webinar to learn:

  • Why larger-format wafers are becoming increasingly popular in the solar industry
  • How these changes impact tracker design and the Voyager+ solution
  • How equipment manufacturers can prepare and solve for this change
