Silicon Pyranometer
SP Lite

SP LITE can be used under all weather conditions. The sensor measures the solar energy received from the entire hemisphere. SP LITE is ideal for measuring available energy for use in solar energy applications, plant growth, thermal convection and evapotranspiration.

SP LITE uses a photodiode detector, which creates a voltage output that is proportional to the incoming radiation. Also due to the unique design of the diffuser, its sensitivity is proportional to the cosine of the angle of incidence of the incoming radiation, allowing for accurate and consistent measurements.

.

SP LITE is easy to use. It can directly connected to voltmeter or data logger. Direct readout in Watts per square meter (Wm-2) can be derived from the measured voltage divided by the calibration coefficient.

The SP LITE Sillicon Pyranometer compares favorably to ISO 9060-specified First Class Thermopile Pyranometers under clear & unobstructed natural daylight conditions, and fully complies with CE Directives.
