Nextracker’s TrueCapture Software: Optimizing Solar Energy Production with Advanced Technology
Nextracker’s TrueCapture™ is a state-of-the-art intelligent yield optimization and control software designed to enhance solar plant performance by up to 4 percent annually. This innovative solution addresses common challenges in solar tracking, particularly issues like row-to-row shading and terrain loss, which can significantly hinder energy generation, especially in areas with sloping or uneven terrain.
The TrueCapture Split Boost mode utilizes Nextracker’s independent-row architecture to reduce shading on a row-by-row basis. This is particularly effective during certain times of the day, allowing the bottom half of half-cut/split-cell modules to experience shading, thereby maximizing energy production. By employing advanced sensor arrays, onsite data processing, and sophisticated algorithms, TrueCapture optimizes the angle of each row of solar panels to capture the maximum amount of sunlight, even in conditions with diffuse lighting. This adaptability makes it particularly suitable for locations with complex topographies and varying pile heights, which are becoming more common as solar projects expand into more challenging environments.
One of the standout features of TrueCapture is its ability to optimize energy production by tailoring its strategies to the specific conditions of each site. It employs a suite of advanced algorithms, including the Zonal Diffuse Mode for capturing scattered light during overcast conditions and the Split Boost Row-to-Row Mode for maximizing energy output. These algorithms can adjust in real-time, ensuring that solar trackers remain in the optimal position to maximize energy generation.
TrueCapture has demonstrated proven gains across over 50 GW of projects globally, validated by annual field-measured inverter data from independent engineering firms such as Enertis, DNV, Black & Veatch, and Leidos. This validation offers bankable improvements for project developers and investors, making TrueCapture not only a technological advancement but also a sound financial choice for solar energy projects.
Incorporating Nextracker’s proprietary sensors, 3D digital twin modeling, and a robust cybersecurity-compliant control system, TrueCapture represents the future of solar energy optimization, delivering consistent, reliable performance and enhanced financial returns for solar power operators.
