Core Sensor Configuration for Photovoltaic Environmental Weather Station

NiuBoL Photovoltaic Environmental Weather Station: Core Component for B2B Photovoltaic Project Environmental Perception and Safe Operation & Maintenance

In the engineering construction and long-term operation and maintenance of centralized and distributed photovoltaic power stations, system integrators, IoT solution providers, project contractors, and engineering companies require highly reliable and compatible on-site environmental monitoring equipment to support power generation performance evaluation, equipment safety protection, disaster risk management, and data-driven optimization. The NiuBoL photovoltaic environmental weather station series products, with integrated or modular design as the core, integrate key sensors such as solar irradiance, module temperature, ambient temperature and humidity, wind speed and direction, rainfall, etc., providing industrial-grade precision and open communication interfaces. It has become the preferred perception layer solution for many B2B partners to build photovoltaic SCADA extensions, performance ratio (PR) analysis systems, and intelligent operation and maintenance platforms.

Core Sensor Configuration: Key Parameter Acquisition for Photovoltaic Power Generation and Safety

The NiuBoL photovoltaic environmental weather station optimizes sensor selection and protection design for the long-term outdoor exposure characteristics of photovoltaic power stations. The main parameters include:

• Solar Irradiance: Total irradiance (POA/GHI), plane-of-array irradiance, range 0～2000 W/m², accuracy ±2-3%, typically using silicon photocell or thermopile sensors, supports module plane installation to achieve real-time power generation potential assessment.

• Module Temperature: Backplane/surface temperature, range -50～150℃, accuracy ±0.5℃, resolution 0.1℃, PT100 or thermistor probe, directly attached to module frame.

• Ambient Temperature and Humidity: Air temperature -40～80℃ (±0.5℃), relative humidity 0～100%RH (±3-5%RH), digital composite sensor.

• Wind Speed and Direction: Ultrasonic or mechanical type, wind speed 0～60 m/s (accuracy ±0.3+3%FS), wind direction 0～360° (accuracy ±3°).

• Rainfall: Tipping bucket rain gauge or piezoelectric rain gauge, resolution 0.1-0.2 mm, cumulative accuracy ±5-10%.

• Optional Extensions: Atmospheric pressure (10～1100 hPa, ±1.5 hPa), atmospheric electric field/lightning counter, module surface soiling sensor (soiling), snow depth sensor.

All sensors support hot-swapping, automatic identification, IP65/IP67 protection rating, operating temperature -40～80℃, MTBF>50,000 hours, adaptable to extreme environments such as deserts, plateaus, coastal areas, etc.

Photovoltaic Environmental Weather Station Communication Protocols and System Integration Capabilities: Efficient Access for Engineering Projects

The NiuBoL photovoltaic environmental weather station prioritizes support for mainstream industrial and IoT protocols to ensure seamless docking with photovoltaic inverters, combiner boxes, SCADA, and cloud platforms:

• Wired: Modbus RTU (RS485), Modbus TCP/IP (Ethernet)

• Cloud: MQTT client (direct connection to Alibaba Cloud IoT, Huawei Cloud IoT, AWS IoT, etc.), supports TLS encryption

• Extensions: Optional 4G/NB-IoT module, LoRaWAN (low-power wide-area scenarios)

• Edge Functions: Local threshold alarms, data caching (disconnection retransmission ≥48 hours), simple preprocessing

System integrators can directly map Modbus registers to PLC or edge gateways; engineering companies can utilize SDK to develop protocol conversion or custom data services; solution providers can build MQTT topic architecture to achieve unified aggregation and analysis of multi-station data.
