Calibrated cells - MET
Calibrated cells - MET
It is used to determine the solar radiation incident on the plane in which it is placed, which normally coincides with that of the photovoltaic field. It is made of crystalline silicon and is encapsulated in the same way as the modules. On the back it has a box from which a bipolar cable comes out (with the positive and negative marked), and a label that provides the exact value of the calibration.
Calibrated 6" compensated cell
The calibrated compensated cell is a precision electronic measuring instrument that allows you to measure solar radiation, the cell's own temperature and the ambient temperature. The instrument comes with a calibration certificate. It is advisable to recalibrate it depending on its use and the conditions in which it is used. For further information, please contact Atersa's Sales Department.
Calibrated cell 6" compensated 4-20mA ò 0-65mV
The 4-20 mA calibrated cell is a precision electronic measuring instrument that allows you to measure solar radiation.
Two independent analogue outputs, proportional to the measured magnitude, provide a standard 4-20 mA or 0-65 mV current level, adapted to the inputs of most inverters, PLCs and data acquisition systems. For more information, please consult ATERSA's Sales Department.

Supporting structures
One of the most important elements in a photovoltaic installation to ensure optimum use of solar radiation is the support structure, which is responsible for supporting the solar modules, providing the most suitable inclination for the modules to receive the greatest amount of solar radiation throughout the year.
Atersa, in addition to its A1 and VA-290/3 structures, offers support structures from other manufacturers.
Two types are available:
- A-1 Aluminium bracket set for 1 module.
- Aluminium frame for 3 x 6" 6x12 72-cell panels model VA-290/3
Street lamps
Photovoltaic solar energy is the best solution for public lighting in places that are isolated from the electricity grid, or where its use is expensive or difficult. ATERSA's equipment fulfils this function, with minimum costs and reduced maintenance.
There are 3 types:
- Led ND street lights
- Led ND luminaires
- FAR-50 12 V waterproof
