RPCS completes 11 new solar tracker projects in Texas

RP construction services

RP Construction Services (RPCS) just completed 11 solar sites as part of a growing portfolio of projects in Texas for the Pedernales Electric Cooperative. RPCS, responsible for the portfolio’s solar tracker installation, partnered with site developer and global energy firm Renewable Energy Systems (RES) and general contractor Performance Contracting, Inc.

The 11 projects rely on the DuraTrack HZ v3 single axis tracker from Array Technologies. This technology keeps the modules following the sun on its course throughout the day, ensuring up to a 20 to 25 percent increase in energy production over fixed-tilt systems. The sites also feature rigid thin-film solar panels from First Solar, an American photovoltaic manufacturer and provider of utility-scale power solutions. RPCS, Array Technologies’ DG partner, designs and installs single axis solar tracker systems across the country, with hundreds of projects to date in the utility and distributed generation markets.

“We love working for the RES team and are very proud of these projects,” says RPCS Chief Sales Officer Alex Smith. “Having 11 projects underway at one time is one of the things that RPCS does best for portfolio companies, and we are really excited to see all the First Solar panels on top of ATI trackers. It’s the best combination of price and speed of installation, which has al-lowed us to execute these projects so cleanly. The sites turned out beautifully and we’re thrilled for the opportunity to work together with RES and PCI.”

The portfolio of projects utilized decommissioned agricultural land leased from local land owners and was flexibly designed to minimize environmental impacts by requiring no major grading. RPCS trained dozens of Texas locals on the installation over the course of the projects, working alongside the local electricians and general contractor labor. The projects have all been injury-free.

Wes Allen, RPCS Superintendent, says, “We had a lot of fun training the local labor. They under-stood what it meant and what it took to build a quality tracker for the community. Because of the quality of work, we requested some of them travel with us to complete the portfolio in oth-er parts of Texas. I received a lot of positive feedback from the locals, and they really enjoyed working with RPCS and can’t wait to build another project.”

Report by TÜV Rheinland explains how Array Technologies trackers drive O&M costs down 37 percent

Array Technologies announced results of an independent analysis by TÜV Rheinland that indicates Array’s flagship tracker, the DuraTrack HZ v3, delivers 4 Cents/Watt DC higher Net Present Value (NPV) and 6.7 percent lower Levelized Cost of Energy (LCOE), driven by 37 percent lower lifetime O&M costs.

Array Technologies DuraTrack

The analysis found that Array’s architecture has higher structural integrity. With a patented mechanical load-release system, Array’s trackers are less susceptible to torsional galloping and consequential damage to solar modules. The DuraTrack HZ v3 withstands high wind loads in all positions, unlike architectures that rely on active stow and a complicated chain of electronic, radio, and motor systems to survive.

TÜV analysts performed an economic and risk analysis of two tracker architectures: one driven by a single motor linked by a rotating driveline to multiple tracker rows; and another where tracker rows operate as self-contained units, each with a dedicated photovoltaic (PV) panel, battery, motor and other system components. TÜV’s analysis includes descriptions of the technical characteristics of each system, followed by a Failure Modes and Effects Analysis (FMEA) to determine high-risk components. A cost of failure analysis of those components was performed, concluding with a LCOE / NPV analysis to assess the economic impact of the two technologies on developers, owners, financiers, and insurers of utility scale solar power plants.

“Reliability is the cornerstone of responsible solar industry growth,” said Array Technologies CEO and founder, Ron Corio. “Without dependable PV modules and tracking systems, the solar industry will struggle to continue down its path of innovation and expansion. This third-party validation from TÜV confirms what we have been claiming for nearly 30 years: that the engineered simplicity in our trackers truly is the best long-term option for solar project owners.”

TÜV Rheinland study explains reliability of Array Technologies’ Trackers

Array Technologies DuraTrack

Reliability and reduced O&M costs are key metrics when choosing among solar tracking systems. At SPI, TÜV Rheinland reveals an in-depth study of Array Technologies’ DuraTrack HZ v3 that indicates the DuraTrack is “300 × less likely to experience catastrophic failure during wind events than single-row competitors that rely on stow.”

Array Technologies is the main supplier of centralized drive trackers in the industry, which the company maintains allows for a robust design and a unique wind mitigation strategy that avoids module stress, fatigue failure and torsional galloping issues during high stress wind events.

TÜV analysts performed an economic and risk analysis of two tracker architectures: one layout driven by a single motor linked by a rotating driveline to multiple tracker rows; and a competing design where tracker rows operate as self-contained units, each with a dedicated photovoltaic (PV) panel, battery, motor and other system components. TÜV’s analysis includes descriptions of the technical characteristics of each system, followed by a failure modes and effects analysis (FMEA) to assess risk associated with component failures, and concluding with a levelized cost of energy (LCOE) / Net Present Value (NPV) analysis to assess the economic impact of the two technologies on developers, owners, financiers, and insurers of utility scale solar power plants.
