Weather Stations for Solar Power Monitoring

Parameters for Weather Monitoring at Solar Projects

Environmental monitoring is critical to optimizing the efficiency of solar power generation.

Solar radiation (irradiance): The most important measurement, key to monitoring availability of sunlight.

Temperature (ambient/panel): Critical relative to performance as increasing temperatures correlate to decreased efficiency.

Wind speed/direction: Less critical, however, wind is a cooling factor which affects efficiency.

Precipitation: May interfere, especially in solid form.

Flexibility, Automation, Integration

Three turnkey meteorological (met) monitoring systems provide options suitable for solar energy projects of any scale. Our standard systems can be customized to suit most requirements.

  • Professional-grade sensors
  • Various solar radiation sensor classes
  • Multiple panel temps option

Multiple Interfaces and monitoring options (Modbus RTU, Modbus TCP, BacNet, Browser Interface and more) automate data collection and integrate with SCADA or other plant monitoring systems.


We’ve been in the weather monitoring business for over 35 years and working specifically with the solar energy industry since 2009. We’ve provided weather stations to hundreds of solar energy projects from small to utility-scale.

Easy Installation and Operation Saves Money

Our weather stations are preferred for ease of installation. The systems come complete, tested and pre-configured to facilitate easy installation by your local site electrician or electrical contractor. They do not require programming or special training to install, operate and maintain.

No long-term contract required. You own the equipment and the data. We are readily available for free technical assistance in the unlikely event it is required.

Your weather stations are quality and your service is outstanding. Way to go!"
