Independent analyst, TÜV Rheinland PTL (TÜV), recently released a report on the economic and risk analysis of two predominant tracker architectures: centrally driven architecture (centralized) and individual row driven architecture (decentralized). The analysis examined components, design, and ability to withstand environmental conditions common to PV power plants – including events such as sand storms, sustained high winds and when systems are exposed to large temperature variations.
Given wide ranging environmental conditions and climates in the LATAM region, solar tracker reliability has become an area of focus for it’s impact on O&M and long-term costs. TÜV’s analysis delivered a range of favorable findings regarding individual components and system design of the centralized system. In contrast, this report takes a deep look at the impact of these findings on utility-scale solar in the LATAM region.
The report highlights the following benefits of Array’s centralized tracking technology over the competing architecture:
“It is vital that utility-scale PV developers do their due diligence when it comes to tracker system selection throughout Latin America. This new report demonstrates how the risks inherent to some tracker systems can have a tremendous impact on a project’s viability and profitability over its lifetime.”
