Turning Data into More Gigawatt Hours (GWh) & Lower O&M Costs
Our patented, field-proven advanced monitoring and control software has been validated by independent engineers, embraced by financial institutions and developers, and successfully deployed across gigawatts of solar power systems worldwide.
Advanced monitoring and control software
Real-time analysis and diagnosis
Optimized energy harvest and plant performance
Extreme weather risk mitigation
Maximize financial returns
By pairing high-performing PV systems infrastructure with advanced software and data analytics platforms, Nextracker equips power plant owners and operators with the ability to more accurately forecast energy goals by delivering consistent and reliable data-driven performance, extended system lifetime, enhanced solar plant efficiency, and maximized financial returns. By seeing into the electrical and mechanical health of our trackers at each plant, we enhance our real-time analysis and diagnostic capabilities, allowing us to be more proactive on our customers’ behalf. Our advanced solar tracker control and monitoring software systems, TrueCapture™ and NX Navigator™, boost solar plant production, improve monitoring and control capabilities, mitigate the risk of inclement weather conditions such as hailstorms, hurricanes and snow, and enhance owner return on investment.
TrueCapture: Adapting to the Real World
The TrueCapture™ intelligent, self-adjusting tracker control system has been field-proven to increase typical PV power plant energy harvest by up to 6 percent. The smart tracker yield optimization system boosts solar power plant production by continuously optimizing the tracking algorithm of each individual row in response to site features and changing weather conditions.
Predictive Control Software: TrueCapture combines advanced sensor, weather forecasting and machine-learning technologies to maximize energy yield. With its smart data capture and model-based predictive control software, TrueCapture helps customers maximize the benefits of their Nextracker systems, generating more revenues with higher energy yields, better availability, and lower operating costs.
Better Performance in Difficult Conditions: The real world isn’t flat, and a growing number of solar project sites feature uneven or undulating terrain. TrueCapture continuously dispatches optimal tracking algorithms to each tracker row, correcting for shading anomalies caused by uneven ground and changing weather conditions. The increase in power production widens the “shoulders” of the power production curve for any given day, resulting in better performance and lower LCOE.
Machine-Learning, Optimized Tracking: Proprietary smart panel sensors provide real-time shading information on each tracker row, which is then processed by machine-learning software to build a virtual 3D model. TrueCapture’s intelligent control engine integrates the model with the latest meteorological data to calculate and send optimized tracking commands to every row.
NX Navigator: Operational Control and Risk Mitigation
NX Navigator software gives utility-scale PV plant owners another layer of monitoring and control beyond TrueCapture, increasing production yield, and enabling reliable operation across a wide range of severe weather conditions.
Real-Time Sitewide Monitoring: Featuring an intuitive graphical user interface, NX Navigator helps plant managers monitor timely sitewide information of key parameters. Precise array and angular value data are collected at the site, subfield, and individual tracker levels. Plant operators can instantly locate the tracker equipment on a digital sitemap, select and command PV arrays into various maintenance modes, filter and identify various tracker states on the digital map, and analyze irradiance and tracker angle heat maps.
O&M Command and Control: NX Navigator allows authorized PV plant operators to schedule maintenance operations such as cleaning and mowing, and instantly command the tracker for extreme weather events such as hail, hurricanes, and heavy snow.
Hailstorm Risk Mitigation: In the case of hail, a single operator command will rapidly put the entire solar array into a safe 60-degree stow angle. Hail cannon tests conducted at the Renewable Energy Test Center (RETC) show that this action will have the benefit of tripling the hail resistance of PV modules compared to a horizontal angle, dramatically reducing damage potential. In the case of snow shed, an authorized operator can preschedule up to two snow shed operations in a single day, increasing production by reducing snow cover on solar panels. TrueCapture™ is an intelligent, self-adjusting tracker control system that increases typical PV power plant energy by up to 6%. TrueCapture boosts solar power plant production by continuously optimizing the tracking algorithm of each individual row in response to site features and changing weather conditions. Optimize with Smart Control TrueCapture solves both challenges with a unique, integrated approach. Over the course of the day, TrueCapture continuously dispatches optimal tracking algorithms to each tracker row, correcting for shading anomalies caused by uneven ground and changing weather conditions. As shown in the accompanying chart, the increase in power production widens the “shoulders” of the power production curve for any given day, resulting in better performance and lower LCOE.
Customer Requirements Available for both NX Gemini 2-in-portrait tracker and NX Horizon, TrueCapture is compatible with most project sites — contact your NX sales representative to learn more about how to take your performance to the next level.
Advanced Monitoring and Control Software for Solar Power Plants
NX Navigator™ is a next-generation smart tracker control system that enables PV power plant owners and authorized operators to monitor and securely control their PV systems. This enhanced control system increases production yield and enables reliable operation across a wide range of weather conditions. Severe hailstorms can cause significant damage to solar arrays, and asset owners with power plants in hail-prone areas often incur increased insurance premiums as a result. NX Navigator mitigates this risk with its hail-stow feature, which permits a single operator command to rapidly put the entire solar tracker array into a safe 60-degree stow angle to reduce hail impact losses. Tests conducted at the independent Renewable Energy Test Center (RETC) using a calibrated hail cannon determined that based on historical hail events in the U.S., the hail-stow feature in NX Navigator increases the survivability of PV panels from 81.6% to 99.4%, a 30X increase in survivability. The RETC independent engineer report, “Hail Resistance Testing and Analysis of Results: Evaluation of Nextracker Hail Stow,” is available under NDA to Nextracker clients.
Next-Generation Monitoring System NX Navigator’s intuitive graphical user interface helps plant managers monitor timely sitewide information of key parameters. Precise array and angular value data are collected at the site, subfield, and individual tracker levels. NX Navigator allows you to easily interpret status and performance charts such as: • Tracker system availability, indicating the percentage of operational or accessible equipment for a chosen time period • Tracker usage, showing
