greenTEG’s gSKIN® Heat
Flux Sensor enables fast and highly precise solar radiation
measurements (i.e. ultraviolet and near-infrared radiation). Precise
data on solar radiation is indispensable for the optimization of
photovoltaic installations, in meteorological research or in building
Solar measurement applications:
Optimization of photovoltaic installations:
The power output of a photovoltaic system depends on its alignment
towards the sun at any given time. The ability to gather precise
data quickly is thus crucial to optimize the efficiency of
photovoltaic installations. The gSKIN® enables you to collect data
on solar radiation, which in turn serves as an important reference
for predictions on the power output of PV systems, the monitoring of
their efficiency, decisions on maintenance (cleaning) and many more.
Precise data in meteorological research:
The sun has a profound influence on all meteorological processes.
Thus precise data on global solar radiation (direct and scattered
solar radiation) is the basis for research and predictions in
Smart building automation systems:
To increase the energy efficiency of buildings smart automation
systems gain increasing importance. These systems regulate processes
according to many environmental parameters, whereof the most
important one is solar irradiation. The gSKIN® can for example be
used to regulate sun blinds and heating automation in buildings in
order to reduce its overall energy consumption.
To measure solar radiation, the gSKIN® can either be used as is or as
a built in part of a pyranometer or other measurement systems. When
solar rays hit the black coated sensor they are converted into heat,
which in turn is converted into an output voltage by the ultra-sensitive
thermopiles of the sensor. To calculate the heat flux, the output
voltage is divided by the sensor-specific sensitivity. You can easily
read-out the signal with a datalogger or a volt meter.
Advantages of the gSKIN® for solar measurements
The following features make the gSKIN® the ideal tool for solar
Fast rise times (sub-second)
A homogenous sensitivity across the sensor surface
Absolute flat surface (no topology) for best measurement results
Customized sensor designs to ensure best performance for
Measurement of all wavelengths with the same sensitivity
The sensor’s output is linear to the measured solar power. This
guarantees easy read-out.
