The success of a solar farm is directly linked to the optimal performance of its solar panels. Experienced system designers, decision-makers, and leading manufacturers rely on advanced data acquisition systems to ensure the consistent and efficient energy output required for maximum reliability.
Solar arrays feed power into the electrical grid, and any reduction in their energy output can significantly impact overall efficiency and profitability. Detecting and addressing issues such as prematurely degrading panels is crucial for maintaining optimal performance. Continuous power output monitoring from solar panels is critical to identifying these issues early, ensuring steady energy production and preventing costly downtime.
AstroNova, a leader in data acquisition and recording for 55 years, recommends the following components for such monitoring:
- AstroNova Daxus® DXS-100 Data Acquisition System: The core system for capturing and processing data.
- NIDX-16 Voltage Input Module: Provides precise voltage measurements for accurate monitoring.
- Clamp-on Current Transformers: These allow current measurement without disrupting operations by converting panel current to voltage.
- Photovoltaic Sensors: Measure light intensity, a critical factor in panel performance.
- Temperature Sensors: Monitor ambient temperature conditions, which can influence energy output.
The AstroNova Daxus DXS-100 system simultaneously measures multiple currents, voltages, ambient temperature, and light intensity. Clamp-on current transducers convert the panel current into voltage for non-intrusive measurement. Additionally, DC-to-DC converters and thermocouple-to-analog converters simplify the connection of light sensors and K-type thermocouples to the NIDX-16 input module.
Data from multiple panels are consolidated into a single file with time and date stamps, creating a comprehensive record of panel performance over time. Thanks to its built-in battery backup, the Daxus system stores all data locally on a solid-state drive, ensuring no critical information is lost, even during a power outage. The system can function autonomously or be connected to a laptop for real-time data viewing and archiving via the Daxus application software.
By using the Daxus solution, operators can quickly identify and address issues with underperforming solar panels, thereby ensuring maximum efficiency and profitability. Monitoring ambient conditions alongside panel data allows operators to compare outputs effectively and assess the impact of varying weather conditions on solar farm performance.
The AstroNova Daxus DXS-100 system, with its advanced monitoring capabilities and flexible design, is ideal for ensuring the efficient operation of solar farms. Providing precise data on key performance parameters, the DXS-100 helps maintain optimal solar panel performance, prevent issues, and ensure a reliable supply of renewable energy.
