Myanmar 50 MWp Solar PV Project
RK900-01 PV Weather Station for Environmental Monitoring
Understanding the weather at a photovoltaic plant helps put its generation performance into context.
At a 50 MWp solar photovoltaic project in Myanmar, the RIKA SENSOR RK900-01 PV Weather Station is installed within the solar farm to support environmental monitoring.
The project photograph shows a mast-mounted sensor assembly and protective equipment cabinet beside the PV array. This installation brings weather measurement equipment into the operating environment of the plant, providing a local reference for reviewing generation conditions.
Project Background
Electrical output alone does not describe all the conditions under which a photovoltaic plant operates. Available sunlight, module temperature and the surrounding weather provide additional context when reviewing generation records.
For a 50 MWp installation, a weather station at the plant provides a way to collect local environmental information. Reviewing those measurements alongside electrical records can help operators investigate output fluctuations and plan further checks when performance differs from expectations.
Environmental Context for PV Generation
Available Solar Energy
Irradiance changes as clouds move and the sun's position shifts. A local radiation record helps explain why generation can vary even when the electrical equipment remains in the same operating state.
Wind and the Array Environment
Wind observations describe conditions around the array and offer context for reviewing the outdoor environment experienced by modules, mounting structures and maintenance personnel.
Temperature and Humidity
Air conditions help describe the plant's operating environment. Where module temperature is also measured, it provides a further reference for examining the relationship between sunlight, module heating and electrical output.
RK900-01 Monitoring Options
The RK900-01 is a configurable photovoltaic weather station. Available measurements include solar irradiance, wind speed, wind direction, air temperature, relative humidity and PV module temperature.
| Parameter | Available Range | Specification |
|---|---|---|
| Solar irradiance | 0–2000 W/m² | Class B/C sensor options |
| PV module temperature | −50°C to +100°C | ±0.5°C accuracy |
| Wind speed | 0–45 m/s | 0.1 m/s resolution |
| Wind direction | 0–360° | ±3° accuracy |
| Air temperature | −40°C to +60°C | ±0.5°C accuracy |
| Relative humidity | 0–100% RH | ±3% RH accuracy |
These are available product specifications. Installed sensors, radiation measurement arrangements and acquisition equipment depend on the selected project configuration.
Installation at the Myanmar Project
The project photograph shows a cup anemometer and wind vane on the upper crossarm, a domed solar radiation sensor near the top of the assembly, and a radiation shield mounted below. A protective cabinet is positioned beneath the sensor assembly, with cables routed along the mast.
This arrangement brings several environmental sensing points together at one location beside the PV array and provides an accessible area for equipment inspection.
Check radiation sensor orientation and shading, wind sensor clearance, cable protection and cabinet sealing. During setup, verify sensor connections, recorded values and timestamp alignment before using the records for plant analysis.
Data Recording and Integration
RK900-01 configurations can use a data logger for display and storage or a suitable communication gateway. Ethernet, 4G and Wi-Fi options are available according to the selected equipment.
For plant analysis, environmental records should cover the same periods as the electrical data. Consistent timestamps, clearly identified sensor channels and appropriate recording intervals make comparisons easier and help operators trace gaps or unexpected readings.
Value for Plant Operations
Compare output fluctuations with the sunlight and weather recorded during the same period.
Use environmental context to guide further checks when reviewing unusual operating trends.
Retain weather records that can be reviewed alongside electrical performance over time.
The Myanmar 50 MWp solar PV project demonstrates the use of the RK900-01 within a photovoltaic installation. With suitable acquisition equipment and plant records, local weather measurements provide a practical reference for understanding operating conditions and reviewing generation performance.
