First Solar Tracker HIGHER ENERGY YIELDS WITH INTELLIGENT TRACKING RAPID INSTALLATION Streamlined mechanical structure and preassembled components for easy installation Minimal site preparation needed with low-impact on the environment Engineered for high-velocity installation with few individual parts and no specialized installation tools required for rapid infield deployment First Solar Tracker is a uniquely engineered, single-axis tracker designed to optimize the performance of First Solar PV modules and maximize energy production. These proven and reliable systems combine uncomplicated, low-environmental-impact installation with up to 25 percent higher energy yields than fixed mount systems. PROVEN ENERGY YIELD ADVANTAGE DAILY POWER PRODUCTION BOOST FROM TRACKING • Proven to generate up to 25 percent more energy than conventional fixed mount systems • Smart control system with WindShift™ Technology automatically adjusts the structure’s position during high wind conditions, lowering stress on components while maximizing energy yield • Demonstrated annual energy increase by using an optimized true-tracking algorithm, compared to traditional backtracking First Solar Tracker follows the sun throughout the day to maximize energy output. ADVANCED PERFORMANCE AND RELIABILITY • Efficient design requires no scheduled maintenance on any parts including bearings and actuators • Integrated tracker controller monitors system function, collects data, and reports status for each row and across the entire plant First Solar, Inc. | firstsolar.com | info@firstsolar.com 02012_DS_A4_01AUG14 CONVENTIONAL TRACKER COMPARED TO FIRST SOLAR TRACKER CONVENTIONAL “GANGED” TRACKER ARCHITECTURE DISTRIBUTED ACTUATION ARCHITECTURE™ With single tracker systems, a single problem can shut down a large portion of the array (typically 200-500kW). With the First Solar Tracker, issues can be isolated to smaller portions of the array (~6kW). FAILED MOTOR/ACTUATOR FAILED MOTOR/ ACTUATOR POWER METER POWER METER Distributed Actuation Architecture uses independent low-voltage DC linear actuators on each tracker to maintain continuous system performance. • Maximizes energy yield by limiting point of failure to single tracker in array • Easier installation on sloped terrain or irregular shaped sites means that a smaller footprint is required STANDARDS TECHNICAL SPECIFICATIONS Tracker Controller and Actuator UL3703 Tracker Weather Station Tracker Gateway Optional Backup Power System (BPS) Architecture Distributed Actuation KW per Tracker Approximately 5.8 kW (depending on the module used) UL61010 Actuators per Tracker 1 UL61010 Certifications FCC, CE (as Applicable) Controls True Tracking – proven to give increased energy yield and thus preferred over backtracking when used with First Solar thin film modules, Wind Shift™, obstruction sensing, GPS timederived positioning Actuation DC Electric, 0.050 kWh / Day / Tracker max energy usage (including controller) Range of Motion +/- 45° from Zenith Anemometer Dual Anemometers with 15 ft.
