The Honde Technology Solar Tracking System with dual install plates is an industrial-grade solution engineered for high-accuracy photovoltaic research and utility-scale performance monitoring. Utilizing a sophisticated dual-mode positioning architecture—fusing real-time GPS data with active four-photodiode sensor tracking—the system maintains a high precision of ±0.3°. Its unique dual-plate design enables the simultaneous measurement of Global Horizontal Irradiance (Total Radiation) and Diffuse Horizontal Irradiance (Scatter Radiation) via a specialized black ball shading technique. This integrated platform facilitates the precise calculation of Direct Normal Irradiance, providing the essential data required for advanced solar resource assessment.
Why Dual-Plate Monitoring Matters for Modern Solar Projects
Achieving scientific-grade accuracy in solar instrumentation requires the ability to differentiate between the various components of solar radiation. The Honde system incorporates an agnostic mounting interface with two primary positions, labeled Pyranometer A and Pyranometer B, to perform differential analysis:
- Total Radiation (Pyranometer A): This sensor captures the global irradiance directly, providing a baseline for total energy availability.
- Scatter Radiation (Pyranometer B): This position features a dedicated shading mechanism (the “black ball”). By physically shading the sensor from the direct solar disk, it isolates the diffuse light or scatter radiation.
By acquiring these two streams simultaneously, the system replaces manual estimation with empirical data. Engineers can accurately determine the “Direct” radiation component (Total – Scatter = Direct), fulfilling the rigorous data requirements of utility-scale audits and atmospheric research.

Core Technology: GPS and Four-Photodiode Sensor Fusion
Our system’s reliability is predicated on a “Dual-Mode Positioning” strategy that ensures the tracking mechanism remains perfectly aligned regardless of environmental conditions.
- Geospatial Synchronization: The system collects local GPS satellite signals to output precise longitude, latitude, and time synchronization, ensuring the astronomical algorithms are perfectly calibrated to the site location.
- Active Optical Tracking: Four integrated photodiode sensors provide real-time optical feedback, allowing the tracker to fine-tune its orientation based on actual light intensity throughout the day.
- Start-of-Day Recalibration: To eliminate cumulative mechanical or electronic errors, the system is programmed to automatically return to the zero point at daybreak. This “Return to Zero” function ensures every monitoring cycle begins from a perfectly calibrated baseline.
- Processed Data Readout: Beyond raw values, the internal processor performs cumulative calculations by year and month, providing immediate access to long-term radiation trends.
Engineering Insights: Practical Application & Integration
As instrumentation engineers, we recognize that field reliability is as critical as measurement accuracy. The Honde system addresses several common deployment challenges:
- Pro-Tip: Power Management Optimization. While the system supports dual 12W DC power supplies, we recommend utilizing the single-source configuration to power both sensors directly. This reduces on-site wiring overhead and minimizes potential points of failure—a critical consideration in remote solar farm environments.
- SCADA and Substation Readiness: The RS485 output utilizes the standard Modbus protocol, allowing the system to act as a primary data substation. It integrates seamlessly into existing SCADA networks without the need for proprietary gateways.
- Automated Data Synthesis: A major industry pain point is the manual post-processing of radiation data. This system automates the synthesis of solar elevation, azimuth angles, and radiation sensor data, providing a direct readout of high-level metrics via the communication bus.
Modular Flexibility and Customization
The system is built on a modular, hardware-agnostic platform. While optimized for Honde’s high-precision radiation sensors, the dual install plates provide a universal mounting interface. This allows researchers to integrate their own proprietary or third-party pyranometers into the tracking workflow.
Furthermore, the communication architecture is highly adaptable. Depending on site infrastructure and telemetry requirements, the system can be configured with GPS, 4G, or Lora communication modules to ensure robust data transmission in any geographic location.
Conclusion: Bridging the Gap in Solar Resource Assessment
The Honde Dual-Plate Solar Tracking System represents a significant advancement for operators who require more than just basic tracking. By combining robust mechanical engineering with dual-sensor radiation monitoring, it provides the comprehensive data set necessary for sophisticated performance modeling and bankable resource assessment.
