Our certifications guarantee quality and reliability

Performance measurement of renewable energy plants begins by measuring a natural source the energy, be it sun or wind.

You can check the actual production yield from renewable energy by comparing the energy generated from natural sources with that produced by the photovoltaic or wind plant. You can compare the real and the theoretical yield expected during the design phase, monitoring the ROI.

How we produce our measurement sensors:

Our sensors include precision components that guarantee the linearity in measurement, as well as precision, and reproducibility [V.I.M. 3rd Edition] in any expected temperature (-30° ÷ +88°C). This, thanks to circuits that compensate the signal for every temperature variation within the cell.

Each cell is subject to a unique treatment which gives good  measurements stability over time.

The use of high quality materials has allowed the sensors to pass aging tests according to the applicable parameters of the IEC EN 61215 norm – Ageing tests in photovoltaic modules.

Thermopile pyranometers complete the range of sensors that measure solar irradiation. Their measuring range is much wider than those of photovoltaic cells (300 ÷ 2900nm cfr. 330  ÷ 1100nm), particularly suitable for meteorological measurements and for the measurements of global solar energy when it is required by the investor of the photovoltaic system. They are made in accordance with ISO 6090.

Soluzione Solare also produces WINDMETER since 2012. A vane anemometer with RS485 Modbus output in order to offer increased reliability even in environments with strong electromagnetic noise (EMC) or where the signal has to cover long distances.

All our products are made with particular attention to the trueness of measures and cost effectiveness. When specified, WindMeter can be provided with  the MEASNET centre’s calibration certificate.

SENSOR ADJUSTMENTS:

The calibration is carried out individually for each sensor, having as reference a primary sensor calibrated by the Fraunhofer accredited institute.
It is carried out according to the requirements of IEC 60904-4 norms (for sensors in PV cell), and ISO 9847 (for thermopile sensors). In particular, for the strategic importance that the PV cell sensors (or photovoltaic pyranometers) play in the modules and photovoltaic systems performance calculation, a set of rules belonging to the IEC 60904 norms  group that regulate construction and test conditions.
These type of sensors are likely to remain outside for the entire useful life. The experience transferred to attention in production gives our sensors a limited instrumental drift, however inevitable as they are optoelectronic sensors. Compliance with the typical calibration interval recommended in the calibration report allows the sensor not to go out of calibration range (UNI EN 30012).

We also offer calibration services of our sensors through reference cell periodically calibrated by the Fraunhofer Insititute.  Every calibration routine generates a report that we obviously provide.

All the calibration procedures and steps are performed with DAKKS and ACCREDIA certified instruments, providing so the traceability chain for every product.
