INTRODUCTION
Solar radiation at Earth’s surface is typically defined as total radiation across a wavelength range of 280 to 4000
nm (shortwave radiation). Total solar radiation, direct beam and diffuse, incident on a horizontal surface is defined
as global shortwave radiation, or shortwave irradiance (incident radiant flux), and is expressed in Watts per square
meter (W m-2, equal to Joules per second per square meter).
Pyranometers are sensors that measure global shortwave radiation. Apogee SP series pyranometers are silicon-cell
pyranometers, and are only sensitive to a portion of the solar spectrum, approximately 350-1100 nm
(approximately 80 % of total shortwave radiation is within this range). However, silicon-cell pyranometers are
calibrated to estimate total shortwave radiation across the entire solar spectrum. Silicon-cell pyranometer
specifications compare favorably to specifications for World Meteorological Organization (WMO) moderate and
good quality classifications and specifications for International Organization of Standardization (ISO) second class
and first class classifications, but because of limited spectral sensitivity, they do not meet the spectral specification
necessary for WMO or ISO certification.
Typical applications of silicon-cell pyranometers include incoming shortwave radiation measurement in
agricultural, ecological, and hydrological weather networks, and solar panel arrays.
Apogee Instruments SP series pyranometers consist of a cast acrylic diffuser (filter), photodiode, and signal
processing circuitry mounted in an anodized aluminum housing, and a cable to connect the sensor to a
measurement device. Sensors are potted solid with no internal air space and are designed for continuous total
shortwave radiation measurement on a planar surface in outdoor environments. SP series sensors output an
analog voltage that is directly proportional to total shortwave radiation from the sun. The voltage signal from the
sensor is directly proportional to radiation incident on a planar surface (does not have to be horizontal), where the
radiation emanates from all angles of a hemisphere.

SPECIFICATIONS
Calibration Traceability
Apogee Instruments SP series pyranometers are calibrated through side-by-side comparison to the mean of four
Apogee model SP-110 transfer standard pyranometers (shortwave radiation reference) under high intensity
discharge metal halide lamps. The transfer standard pyranometers are calibrated through side-by-side comparison
to the mean of at least two ISO-classified reference pyranometers under sunlight (clear sky conditions) in Logan,
Utah. Each of four ISO-classified reference pyranometers are recalibrated on an alternating year schedule (two
instruments each year) at the National Renewable Energy Laboratory (NREL) in Golden, Colorado. NREL reference
standards are calibrated to the World Radiometric Reference (WRR) in Davos, Switzerland.

Spectral Response
Temperature Response
Mean temperature response of four
Apogee silicon-cell pyranometers.
Temperature response measurements
were made at approximately 10 C
intervals across a temperature range of
approximately -10 to 50 C under
sunlight. Each pyranometer had an
internal thermistor to measure
temperature. At each temperature set
point, a reference blackbody
pyranometer was used to measure solar
intensity.
Spectral response estimate of Apogee
silicon-cell pyranometers. Spectral
response was estimated by multiplying
the spectral response of the
photodiode, diffuser, and adhesive.
Spectral response measurements of
diffuser and adhesive were made with a
spectrometer, and spectral response
data for the photodiode were obtained
from the manufacturer.

Cosine Response
Mean cosine response of eleven Apogee
silicon-cell pyranometers (error bars
represent two standard deviations
above and below mean). Cosine
response measurements were made
during broadband outdoor radiometer
calibrations (BORCAL) performed during
two different years at the National
Renewable Energy Laboratory (NREL) in
Golden, Colorado. Cosine response was
calculated as the relative difference of
pyranometer sensitivity at each solar
zenith angle to sensitivity at 45° solar
zenith angle. The blue symbols are AM
measurements, the red symbols are PM
measurements.
Directional, or cosine, response is
defined as the measurement error at
a specific angle of radiation incidence.
Error for Apogee silicon-cell
pyranometers is approximately ± 2 %
and ± 5 % at solar zenith angles of 45°
and 75°, respectively.

Important: Only use the nylon screw provided when mounting to
insulate the non-anodized threads of the aluminum sensor head
from the base to help prevent galvanic corrosion. For extended
submersion applications, more insulation may be necessary.
Contact Apogee tech support for details.
DEPLOYMENT AND INSTALLATION
Mount the sensor to a solid surface with the nylon mounting screw provided. To accurately measure PPFD incident
on a horizontal surface, the sensor must be level. An Apogee Instruments model AL-100 Leveling Plate is
recommended to level the sensor when used on a flat surface or being mounted to surfaces such as wood. To
facilitate mounting on a mast or pipe, the Apogee Instruments model AL-120 Solar Mounting Bracket with Leveling
Plate is recommended.
Pyranometer model SP-230 comes with a plastic standoff which should be placed between the sensor head and
the leveling plate. The standoff allows for more efficient use of the internal heaters by minimizing possible heating
losses through conduction.
To minimize azimuth error, the sensor should be mounted with the cable pointing toward true north in the
northern hemisphere or true south in the southern hemisphere. Azimuth error is typically less than 1 %, but it is
easy to minimize by proper cable orientation.
In addition to orienting the cable to point toward the nearest pole, the sensor should also be mounted such that
obstructions (e.g., weather station tripod/tower or other instrumentation) do not shade the sensor. Once
mounted, the green cap should be removed from the sensor. The green cap can be used as a protective covering
for the sensor when it is not in use.

CABLE CONNECTORS
Apogee started offering in-line cable connectors on
some bare-lead sensors in March 2018 to simplify the
process of removing sensors from weather stations for
calibration (the entire cable does not have to be
removed from the station and shipped with the sensor).
The ruggedized M8 connectors are rated IP68, made of
corrosion-resistant marine-grade stainless-steel, and
designed for extended use in harsh environmental
conditions.
Inline cable connectors are installed 30 cm from the
head
Instructions
Pins and Wiring Colors: All Apogee connectors have six
pins, but not all pins are used for every sensor. There
may also be unused wire colors inside the cable. To
simplify datalogger connection, we remove the unused
pigtail lead colors at the datalogger end of the cable.
If you ever need a replacement cable, please contact us
directly to ensure ordering the proper pigtail
configuration.
Alignment: When reconnecting your sensor, arrows on
the connector jacket and an aligning notch ensure
proper orientation.
Disconnection for extended periods: When
disconnecting the sensor for an extended period of time
from a station, protect the remaining half of the
connector still on the station from water and dirt with
electrical tape or other method.
A reference notch inside the connector ensures
proper alignment before tightening.
When sending sensors in for calibration, only send the
short end of the cable and half the connector.
Tightening: Connectors are designed to be firmly
finger-tightened only. There is an o-ring inside the
connector that can be overly compressed if a wrench is
used. Pay attention to thread alignment to avoid cross-
threading. When fully tightened, 1-2 threads may still
be visible.
*NOTE: To avoid damaging the pins inside the
connector, finger-tighten the connector by only turning
the metal nut. Do not tighten by turning the black
cable.
Finger-tighten firmly

OPERATION AND MEASUREMENT
Connect the sensor to a measurement device (meter, datalogger, controller) capable of measuring and displaying
or recording a millivolt (mV) signal (an input measurement range of approximately 0-250 mV is required to cover
the entire range of total shortwave radiation from the sun). In order to maximize measurement resolution and
signal-to-noise ratio, the input range of the measurement device should closely match the output range of the
pyranometer.
SP-110: The sensor is self-powered and applying voltage will damage the sensor.
VERY IMPORTANT: Apogee changed the wiring colors of all our bare-lead sensors in March 2018 in
conjunction with the release of inline cable connectors on some sensors. To ensure proper connection to your
data device, please note your serial number or if your sensor has a stainless-steel connector 30 cm from the
sensor head then use the appropriate wiring configuration listed below. With the switch to connectors, we also
changed to using cables that only have 4 or 7 internal wires. To make our various sensors easier to connect to
your device, we clip off any unused wire colors at the end of the cable depending on the sensor. If you cut the
cable or modify the original pigtail, you may find wires inside that are not used with your particular sensor. In
this case, please disregard the extra wires and follow the color-coded wiring guide provided.

Sensor Calibration
All Apogee un-amplified pyranometer models have a standard calibration factor of exactly:
5.0 W m-2 per mV
Multiply this calibration factor by the measured mV signal to convert sensor output to shortwave radiation in units
of W m-2:
Calibration Factor (5.0 W m-2 per mV) * Sensor Output Signal (mV) = Total Shortwave Radiation (W m-2)
5.0 * 200 = 1000
Spectral Errors for Measurements with Silicon-cell Pyranometers
Apogee SP series pyranometers are calibrated under electric lamps in a calibration laboratory. The calibration
procedure simulates calibration under clear sky conditions at a solar zenith angle of approximately 45°. However,
due to the limited spectral sensitivity of silicon-cell pyranometers compared to the solar radiation spectrum (see
graph below), spectral errors occur when measurements are made in conditions that differ from conditions the
sensor was calibrated under (e.g., the solar spectrum differs in clear sky and cloudy conditions, thus measurements
in cloudy conditions result in spectral error because sensors are calibrated in clear sky conditions).
Example of total shortwave radiation
measurement with an Apogee SP-110
pyranometer. Full sunlight yields total shortwave
radiation on a horizontal plane at the Earth’s
surface of approximately 1000 W m-2. This yields
an output signal of 200 mV. The signal is
converted to shortwave radiation by multiplying
by the calibration factor of 5.0 W m-2 per mV.

(1000 W m-2)

Silicon-cell pyranometers can still be used to measure shortwave radiation in conditions other than clear sky or
from radiation sources other than incoming sunlight, but spectral errors occur when measuring radiation with
silicon-cell pyranometers in these conditions. The graphs below show spectral error estimates for Apogee silicon-
cell pyranometers at varying solar zenith angles and varying atmospheric air mass. The diffuser is optimized to
minimize directional errors, thus the cosine response graph in the Specifications section shows the actual
directional errors in practice (which includes contributions from the spectral shift that occurs as solar zenith angle
and atmospheric air mass change with time of day and time of year). The table below provides spectral error
estimates for shortwave radiation measurements from shortwave radiation sources other than clear sky solar
radiation.
Spectral response of Apogee SP series
pyranometers compared to solar
radiation spectrum at Earth’s surface.
Silicon-cell pyranometers, such as
Apogee SP series, are only sensitive to
the wavelength range of
approximately 350-1100 nm, and are
not equally sensitive to all
wavelengths within this range. As a
result, when the spectral content of
solar radiation is significantly different
than the spectrum that silicon-cell
pyranometers were calibrated to,
spectral errors result.

Operation of Heater (SP-230)
Apogee model SP-230 pyranometers have an internal heater to allow for sensor heating during precipitation
events or under conditions of dew, frost, and snow deposition. The heater is designed to keep the water (liquid
and frozen) off the diffuser, though it does not need to be used in order to make measurements of shortwave
radiation. However, if the diffuser has water on the surface, errors can result. Continuously powering the heater
under conditions that do not require heating will not damage the sensor or influence measurements.

pyranometers as a function of
atmospheric air mass, assuming
calibration at an air mass of 1.5.

MAINTENACE AND RECALIBRATION
Moisture or debris on the diffuser is a common cause of low readings. The sensor has a domed diffuser and
housing for improved self-cleaning from rainfall, but materials can accumulate on the diffuser (e.g., dust during
periods of low rainfall, salt deposits from evaporation of sea spray or sprinkler irrigation water) and partially block
the optical path. Dust or organic deposits are best removed using water or window cleaner and a soft cloth or
cotton swab. Salt deposits should be dissolved with vinegar and removed with a soft cloth or cotton swab. Never
use an abrasive material or cleaner on the diffuser.
Although Apogee sensors are very stable, nominal accuracy drift is normal for all research-grade sensors. To
ensure maximum accuracy, we generally recommend sensors are sent in for recalibration every two years,
although you can often wait longer according to your particular tolerances.
To determine if your sensor needs recalibration, the Clear Sky Calculator (www.clearskycalculator.com) website
and/or smartphone app can be used to indicate the total shortwave radiation incident on a horizontal surface at
any time of day at any location in the world. It is most accurate when used near solar noon in spring and summer
months, where accuracy over multiple clear and unpolluted days is estimated to be ± 4 % in all climates and
locations around the world. For best accuracy, the sky must be completely clear, as reflected radiation from clouds
causes incoming radiation to increase above the value predicted by the clear sky calculator. Measured values of
total shortwave radiation can exceed values predicted by the Clear Sky Calculator due to reflection from thin, high
clouds and edges of clouds, which enhances incoming shortwave radiation. The influence of high clouds typically
shows up as spikes above clear sky values, not a constant offset greater than clear sky values.
To determine recalibration need, input site conditions into the calculator and compare total shortwave radiation
measurements to calculated values for a clear sky. If sensor shortwave radiation measurements over multiple days
near solar noon are consistently different than calculated values (by more than 6 %), the sensor should be cleaned
and re-leveled. If measurements are still different after a second test, email [e-mail]
to discuss test results and possible return of sensor(s).

TROUBLESHOOTING AND CUSTOMER SUPPORT
Independent Verification of Functionality
Apogee models SP-110 and SP-230 pyranometers are self-powered devices and output a voltage signal
proportional to incident shortwave radiation. A quick and easy check of sensor functionality can be determined
using a voltmeter with millivolt (mV) resolution. Connect the positive lead wire from the voltmeter to the white
wire from the sensor and the negative (or common) lead wire from the voltmeter to the black wire from the
sensor. Direct the sensor diffuser toward a light source and verify the sensor provides a signal. Increase and
decrease the distance from the sensor head to the light source to verify that the signal changes proportionally
(decreasing signal with increasing distance and increasing signal with decreasing distance). Blocking all radiation
from the sensor should force the sensor signal to zero.
The heaters inside Apogee model SP-230 are designed to mitigate effects from snow, frost, and dew by warming
the sensor body temperature approximately 3 C above ambient air temperature, while under conditions of no
solar loading or radiant heating. A quick and easy check of heater functionality can be accomplished with an
ohmmeter. Connect the lead wires of the ohmmeter to the yellow and blue wires from the sensor. The resistance
should read approximately 780 Ω± 1%.
Compatible Measurement Devices (Dataloggers/Controllers/Meters)
Models SP-110 and SP-230 pyranometers are calibrated with a standard calibration factor of 5.0 W m-2 per mV,
yielding a sensitivity of 0.2 mV per W m-2. Thus, a compatible measurement device (e.g., datalogger or controller)
should have resolution of at least 0.2 mV, in order to provide shortwave radiation resolution of 1 W m-2.
An example datalogger program for Campbell Scientific dataloggers can be found on the Apogee webpage at
http://www.apogeeinstruments.com/content/Pyranometer-Unamplified.CR1.
Effect of Cable Length
When the sensor is connected to a measurement device with high input impedance, sensor output signals are not
changed by shortening the cable or splicing on additional cable in the field. Tests have shown that if the input
impedance of the measurements device is 1 mega-ohm or higher then there is negligible effect on the
pyranometer calibration, even after adding up to 100 m of cable. Apogee model SP series pyranometers use
shielded, twisted pair cable, which minimizes electromagnetic interference. This is particularly important for long
lead lengths in electromagnetically noisy environments.
Modifying Cable Length
See Apogee webpage for details on how to extend sensor cable length
(http://www.apogeeinstruments.com/how-to-make-a-weatherproof-cable-splice/).
