HelioScale Phi

HelioScale φ is a robust, low maintenance and low cost solution for the measurement of GHI, Diffuse (DIF) and Direct Normal Irradiance (DNI) and is therefore suitable for PV, CPV or CSP industries. A Rotating Shadowband Irradiometer (RSI) forms the heart of the station, which allows all 3 solar components to be derived by a fast response photodiode sensor. Outdoor calibration increases the accuracy of the RSIs used in our stations. Weekly cleaning, ease of operation without tracking and good accuracy makes HelioScale φ the most preferred choice of project developers for site qualification, feasibility studies, engineering design and financial bankability of CSP and PV power plants.

With HelioScale φ, you acquire a robust, low cost and low maintenance solution for measurement of Global Horizontal, Diffuse and Direct Normal Irradiance. Its accuracy combined with the ease of operation makes it your first choice for site qualification, feasibility studies or financial bankability of CSP and PV power plants. To contribute to your successful project development we offer:

  • Rugged and precise measurement of global radiation (GHI), as well as diffuse (DIF) and direct (DNI) components of solar irradiance with a Rotating Shadowband Irradiometer (RSI) based on a fast response photodiode sensor 

  • High accuracy due to outdoor calibration of our RSI 

  • Robust stand-alone system with low maintenance requirements 

  • Off-grid power supply consisting of a photovoltaic system including 
12 V backup batteries to ensure operation with low irradiance 
conditions
  • Daily data retrieval via mobile phone networks, satellite or radio con
nections 

  • A calibrated data logging system
  • Measurement data storage in 1 minute resolution for 1 year

The meteorological stations are engineered, assembled and tested by Wilmers Messtechnik. The stations are usually sold to the client, who would then be in charge of recalibration, operation and maintenance. Suntrace offers these services and quality control plus data analysis in an additional package.
