Market Commentary

Sustainability in Action: Array Technologies


Array Technologies is a market-leading manufacturer of utility-scale solar tracking systems. This technology enables solar panels to follow the sun throughout the day, significantly increasing the energy output of solar plants that provide power to thousands of customers. The company has helped more than 900 projects supply over 22,000 megawatts of energy globally throughout its +30-year history.

Oaktree’s Power Opportunities strategy first invested in the company in 2016. The strategy targets companies that provide products and services used to maintain, upgrade, and expand power, utility, energy, water and wastewater infrastructure in North America and Europe. We were interested in Array because we believed that utility-scale solar power generation was poised for significant growth, both domestically and internationally, as this source of clean energy was becoming increasingly cost-competitive with other power sources. Additionally, trackers – like those produced by Array – were deepening their market penetration because projects employing them could produce energy more efficiently than those continuing to use traditional, fixed-tilt systems.

Array had a long track record of successful installations, and we believed its systems offered significant advantages over competing products. For example, the company designed its equipment with fewer motors and components than similar systems, and its technology could be used in a variety of terrains. Array’s systems therefore offered greater flexibility and better reliability than many of its competitors’ products, with lower installation and maintenance costs.


Annual global tracker installations and Array’s sales volumes increased substantially between 2015 and 2017, but the company also experienced growing pains. First, the average selling price of Array’s systems fell by almost 50% in the four years to 2019 due to intense price competition. Also, the company encountered numerous supply-chain and logistical problems as it struggled to keep up with rapidly escalating production demands. Adding to these difficulties, in 2018 the U.S. government imposed a 25% tariff on steel, one of the company’s largest input costs.

The Power Opportunities group used its extensive experience in this industry to help Array overcome these challenges and emerge better positioned for long-term growth. We directed or led a number of important initiatives, working closely with the company’s management team.

  • We helped Array reduce its unit costs by over 30% through improvements in product design and logistics. This allowed the company to refocus on its mission: improving access to clean, reliable solar-powered energy.

  • One of our former colleagues served as a senior advisor to Array. He recruited a new full-time chief executive officer in 2019 who had extensive experience in international sales, manufacturing and supply-chain operations.

  • We helped select new management and operational staff and increased the size and breadth of the sales team, which further professionalized the business. This enabled the company to capitalize on rising demand for trackers, particularly from international customers.

  • We provided Array with much-needed liquidity by making an additional investment and negotiating with the company’s founder to inject more capital.

  • We supported the company as it completed a complex enterprise software upgrade, which improved operational efficiency.

  • We hosted annual summits for Power Opportunities portfolio companies in 2016 and 2018 at which executives, including Array’s management, heard from industry experts and discussed best practices involving a range of topics, including worker safety, employee compensation and key performance metrics.

  • In 2020, we organized a series of webcasts to help Array and other portfolio companies address pandemic-related challenges. The series featured subject-matter experts from PwC, Marsh, Aon Risk Solutions and CEBAT (another Power Opportunities portfolio company, based in Italy, whose operations were affected early in the crisis).


Our efforts to extend Array’s ability to supply the renewable energy industry helped upgrade the company’s operations and boost its earnings and cash-flow generation, dramatically improving gross and operating margins. The pandemic disrupted the company’s activities and delayed certain projects, but Array weathered these difficulties. And it fully paid off its debt by the end of 2020.

The company has helped more than 900 projects supply over 22,000 megawatts of energy during its history.

Importantly, the company benefited significantly from industry tailwinds that were the basis of our initial investment. Worldwide utility-scale solar capacity increased at a compound annual rate of 25% between 2018 and 2021, and pressure on the average sales price of trackers eased. Meanwhile, Array’s technology remained the preferred choice of many in the industry.

This positive backdrop and Array’s impressive financial results enabled the company to complete a highly successful initial public offering in October 2020 – the largest renewable energy IPO in U.S. history at that time. Our investment in the company has now been fully realized, but we’re pleased to watch as Array continues to help owners of utility-scale solar plants produce affordable, clean energy for customers around the globe.

Examples of Array’s Global Impact

Supplied its technology to the Americas’ largest bifacial solar plant. Households will avoid emitting over 800,000 million tons of carbon dioxide each year on average by using the energy provided by this plant instead of power generated by traditional sources.4

Equipped one of the biggest photovoltaic solar plants in Australia, which provides power to more than 115,000 Australian homes each year.5


Provided technology to six solar projects that support the energy needs of around 238,000 homes across Queensland and Victoria, Australia.6

Completed installations in Texas that help supply power to approximately 15,000 households.7


1 Based on trackers shipped as of June 30, 2020.
2 Array Technologies estimated the annual offsets based on the avoided rates equivalent to 18 GW of solar PV projects. Array stated that (1) the estimates for carbon dioxide and particulate matter are calculated using national emission factors from the EPA AVERT 2018 calculator; (2) the water withdrawals estimate is based on the weighted average of median natural gas and coal withdrawals using EIA 2019 data and “Operational Water Consumption and Withdrawal Factors for Electricity Generating Technologies: A Review of Existing Literature,” by Jordan Macknick et al., in Environmental Research Letters, Vol. 7, No. 4, December 20, 2012; and (3) the calculations assume an annual average capacity factor of 20.7% (provided by EPA AVERT) and a DC to AC conversion factor of 1.25.
