PV Evaluation Systems

PV Evaluation Systems

Solar cells and modules usually show a gradual performance decline when deployed outdoors and exposed to environmental conditions.The evaluation systems are designed to measure the performance characteristics and maximum output power of solar cells and modules.

I-V Curve Tracers

I-V Curve Tracers

I-V Curve Tracer are used to measure I-V characteristics of solar Cells, Modules or Strings (Modules in series) it is important to match the measurable output power, respectively output Voltage and Current with the measurement device.

Pyranometer:Solar Radiation Sensor

Pyranometer:Solar Radiation Sensor

EKO MS-series pyranometers comply with the ISO 9060 and WMO standards and are very reliable. The MS-802 highest class ISO Secondary Standard is used for the most demanding applications in PV, Meteorology, field research and solar radiation monitoring of global, tilted and diffuse irradiance.

Pyrheliometer

Pyrheliometer

Pyrheliometers are used to measure the Direct irradiance emitted by the sun in a 5 degree angle. The ISO9060 First Class MS-56 is a research grade normal incidence direct solar irradiance sensor also known as a pyrheliometer or DNI sensor which highly suitable for routine operation on automated Sun Tracker.

Spectroradiometers

Spectroradiometers

The spectroradiometers MS-700/701/710/712 are supplied with a separate power control unit with RS-232/422 serial communication interface. Those can be fully controlled by a PC, where the operating software offers advanced functionalities for data retrieval and data storage.

UV Radiometers

UV Radiometers

The earth's ozone layer plays a very important role in protecting living organisms by absorbing the harmful ultraviolet (UV) radiation. However, the ozone layer became thinner and thinner over the years even though it started to level out during the last decennium.

Pyrgeometers / Net radiometers

Pyrgeometers / Net radiometers

In meteorological applications, infrared or long wavelength radiations are electromagnetic radiations with a wavelength longer than 3.0 µm. Long wave radiations physically relate to temperature and are emitted by all objects on earth. It corresponds to the spectral range beyond the shortwave spectrum of the sun which covers the spectral range 300 nm - 3µm (99.5% of the total solar energy).

Sunshine Duration Sensors

Sunshine Duration Sensors

The WMO has defined sunshine duration as the time interval when direct solar radiation exceeds 120W/m2. There are many ways to measure or calculate sunshine duration from direct or global radiation data.We can offer 3 different methods either based on direct or global radiation measurements.

Sky Scanner

Sky Scanner

The Sky Scanner MS-321LR is designed to measure the luminance and radiance of 145 points in the sky hemisphere. The sensor, with its 11 degrees aperture angle and the tracker, with its two-axis control, together measure the distribution of both luminance and radiance.

Sensor accesories

Sensor accesories

All optional sensor accessories have specific functions to extend the capabilities of the EKO sensors. Besides all EKO sensors most accessoiries can be used in combination with other sensor models. Contact EKO Instruments for further specifications.
