SunSpec Webinar Andrew Murray
Company Profile • Array Technologies is the leading manufacturer of innovative, cost-effective, reliable and robust solar tracking systems. • A pioneer in the solar industry, the company has been providing customers with unequaled expertise for over 20 years. • Array’s trackers are manufactured in the USA and shipped worldwide to customers looking for innovative, yet proven, solutions. • ATI is built on the foundation of a strong technical team, with human capital from the aerospace, military, solar, aviation and investment fields.
Company History • Wattsun Corporation Established in 1985 • 1985 Develops Silicon “flat-plate” PV concentrator module • 1989 Dual-axis closed-loop Polar Axis Developed • Array Technologies Inc. purchases the Wattsun Corporation in 1992 • 1992 ATI Tracker controller patent issued. • 1995 ATI introduces and deploys Dual and Single Azimuth Trackers – patents filed. • 2002 ATI introduces and deploys DuraTrack HZ™ Single Row Single Axis Tracker – patents filed. • 2007 ATI’s DTHZ™ application in first U.S. Utility Scale project • 2012 ATI awarded supply contract for a 268MWDC project, largest solar tracking project in North America to date
DTHZTM Product History • DuraTrack HZ™ Single Row Single Axis Tracker • 2002 DuraTrack HZ™ Single Row Single Axis Tracker introduced - patents filed. • 2007 DuraTrack HZ™ Gear Drive System introduced. – patents filed. • 2007 DuraTrack HZ™ deployment at Alamosa, CO - 6.6 MW – first utility scale system in North America. • 2012 DuraTrack HZ™ installed in over 800MW of projects in the US and International markets • 2012 – ATI meets 1GW milestone for total DTHZTM solar trackers deployed!
Section 2 Title Tracker Background
Tracker History • Late 1960s-70s • First Passive Trackers manufactured • 1980s • Primarily sold to residential off-grid market • First large-scale tracker built in 1983 • Slow but steady growth
Tracker History • 1990s • Trackers lacked cost structure to be implemented large scale • Programs based on system peak ratings(kWp) • Feed-in-tariffs (FIT) programs in late 90s • 2000s • Tracker industry rapidly growing • From 2009-2012 racking systems would be used in 80% of PV sites over 1 MW
Types of Trackers • Single Axis • Horizontal • Rotate about axis parallel to ground http://www.homecsp.com/singleaxis
Types of Trackers • Single Axis Vertical Single Axis (Azimuth Tracker) Tilted Axis http://www.homecsp.com/singleaxis
Types of Trackers • Dual Axis • Azimuth and Horizontal Rotation http://www.solar-energy-for-homes.com/solar-tracker.html
Financial Concerns • Bankability • Project’s ability to be financed • LCOE (Levelized Cost of Energy) • Analysis that takes in a diverse group of variables • Compares Apples to Apples • LCOE evaluations determine if trackers are viable and if so what kind.
Tracker Benefits • Shouldering Effect • Trackers extend production throughout the day and not just peaking at noon. Shouldering Smith, Stephen. “PV Tracker”. SOLARPRO June/July 2011:28-54.
Tracker Benefits • Shouldering Effect • Shouldering lines up well with Peak Grid demand hours Smith, Stephen. “PV Tracker”. SOLARPRO June/July 2011:28-54.
Tracker Benefits • Peak Power • Large PV plants have peak power output caps • Trackers enable 20% more power to be pumped into the grid with the same peak power output as fixed. • Net metering • Electrical Companies pay or give credits to customer for excess electricity • Encourages Residential and Commercial trackers
Tracker Benefits • Increase in performance • Single Axis- Improve PV plant performance by 24% over fixed-tilt while costing 3-5% more • Dual Axis- Improve PV plant performance by 38% over fixed-tilt while costing 12-14% more
Additional Considerations • Location • Geography • Geometry • Ground Coverage Ratio (GCR) • Ratio of land to solar aperture of PV plant Solar PV Balance of System (BOS) Markets: Technologies, Costs and Leading Companies, 2013-2016
Section 4 Title Tracker Monitoring
Tracker Monitoring • Need for monitoring. • Remote sites • Reduce O&M Cost • Increase Uptime • Demand to monitor increasing • No standards • Monitoring company needs to customize each site • Time is wasted
