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.
LOWER LABOR COSTS
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.
