TrueCapture: Adapting to the Real World
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
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 very intelligent technology. Not only do we get more production - three and a half percent in this case - the panel’s get more sun than they got before we operated it without TrueCapture. We are getting materially more production adjusted for solar irradiance. For an owner like us, that’s super valuable.
TrueCapture provides for a genuine uplift on the energy yield on our southeast U.S. projects, which affects the financing of the projects in a positive way.
Nextracker offers one of the most innovative and bankable tracker solutions in the solar market. We actively seek to stay ahead of the curve, as we continue our mission to deliver low-cost, clean energy to Latin America.
