New Report Highlights Impact of Tracker Reliability on Utility-Scale Solar in MENA Region

Centralized tracker architecture delivers lifetime LCOE savings of $12.41 million for 100 MW project

ABU DHABI, UAE – 17 January, 2018Array Technologies, Inc., the pioneer and global leader in solar tracking solutions, brought tracker reliability and its impact on utility-scale solar operations and maintenance costs (O&M) into sharp focus at the World Future Energy Summit (WFES) this week in Abu Dhabi.

Array presented the results of an independent analysis by TÜV Rheinland, which indicated Array’s centralized tracker architecture delivers an LCOE advantage over decentralized systems of 6.7%. This is due largely to lower scheduled and unscheduled maintenance costs. The study further shows how the centralized system’s resilience to environmental risks leads to an increase in a project’s profitability and to long-term investment security.

The analysis was delivered in a first-of-its-kind independent report in which different solar tracker architectures were assessed regarding their durability and reliability. It took into account the extreme heat and strong winds that are prevalent in the Middle East and other parts of the MENA region. The report highlighted these unique environmental challenges facing utility-scale solar projects in the region and the crucial importance of minimizing O&M.

“The MENA region is seeing unparalleled expansion in the development of large scale solar projects,” said Gurmeet Kaur, Communications Director, Middle East Solar Industry Association (MESIA). “The significant sizes of some of these projects and the record breaking low tariffs achieved over the last few years puts the MENA region firmly on the global solar map.”

The report presented at WFES 2018 found that a centralized rotary-drive tracker architecture delivers an LCOE of 2.75 cents/kWh for a 100 MW solar array, while a decentralized architecture can only achieve 2.94 cents/kWh. Over a 30-year expected PV array lifetime, that amounts to LCOE savings of $12.41 million.

“It’s crucial that project developers and EPCs begin to look at the importance of O&M costs when it comes to component selection,” said Array Technologies Executive Chairman, Brad Forth, when presenting the report. “The risks inherent to some tracker systems are significant and can have a massive impact on a project’s viability as well as profitability over 20 or 30 years.”

Key takeaways from the report findings include:

centralized trackers have fewer motors and electrical components, thereby requiring less scheduled and unscheduled maintenance;

 the electrical components deployed in decentralized systems, including lithium-ion battery packs, can be prone to failure in the field, particularly when operating in high temperatures;

 Array’s trackers are less susceptible to torsional galloping and consequential damage to solar modules, due to their patented mechanical load release system; and

 the commercially rated and readily available components for wind mitigation used in Array trackers are more resilient under harsh environmental conditions and can be easily replaced in the unlikely event of failure.

“It was an eye-opening experience to bring together the testing conditions common to the Gulf States and Middle East and tracker reliability for the first time at WFES 2018,” said Array Technologies’ Cesar Alberte. “This discussion is important not only for project developers and EPCs but for the solar industry as a whole – if it is to meet its vast potential in the region.” Alberte recently joined Array Technologies as its new VP of International Sales. Before joining Array, he served as managing director of a global EPC and concessionary with a presence in the Americas, Africa, Europe, India, and the Middle East.
