German Make Nes Soz 03

Nes Soz is a low cost Pyranometer with high accuracy and suited for small to medium sized solar projects. The SOZ-03 pyranometer consists of a mono-crystalline silicon cell (50 x 50 mm ²) with special solar glass. The pyranometer is laminated, hence high UV-resistance and long-term stability.

Accuracy of NES Radiation Sensor Type SOZ-03 is better than 3% (from measuring value) in the range of 150-1200 W/m2 when the solar rays are perpendicular to the surface of the sensor and the spectrum corresponds to AM 1,5.

For all other central European conditions and installations with an inclination of 45° (±20°) directed to the south (±45°) the accuracy of the monthly sums of the solar radiation is better than +-5% compared to an world class 1 pyrometer (W.M.O. first class , ISO 9060) (e.g Kipp&Zonen CMP11).

 

    Key Features:

  • Accuracy of monthly sums compared to a W.M.O. class 1 Pyranometer (e.g. CMP 11) according to ISO 9060: better ±5 %
  • Very small drift of <0.3 / year (experience since 1989)
  • Advanced weatherproof junction box made of UV resistant material with cable gland and screw-less terminal for the connection of the measuring cable
  • High precision shunt resistor directly soldered to the terminals of the cell
  • Linear output signal in the range 0...1500 W/m²
