INTRODUCTION

ATTENZIONE

The remote unit SOLAR-02 has been designed to measure irradiation [W/

m2] and temperature [°C] by means of appropriate probes connected

to it. It can also be used in combination with a MASTER instrument to

carry out the above-mentioned measurements for testing/recording the

eciency of single-phase and three-phase photovoltaic installations.

The unit SOLAR-02 can be connected to the following accessories and MASTER

instruments:

For the sake of brevity, in this manual, the master instruments and the

accessories are indicated with the acronym given in column “Acronym” of the

previous Table 1

The unit SOLAR-02 has the following functions:

• Real-time display of irradiation and temperature values of PV module cells

and environment

• Connection with a irradiation sensor type Irr-P or reference cell type Irr-S2

• Connection to master unit via USB connection (M-USB) or radio frequency

connection (M-RF)

• Synchronization with master unit M-USB or M-RF when starting testing/

recording.

• Measurement of the tilting angle of PV panels

• The remote unit SOLAR-02 is a measuring instrument capable of using

radio frequency for data transfer. For internal reasons it was been adopted

a 2.4GHz harmonized frequency band. The above said radio based device is

built under Class 1 according to the Agreement stipulated among EEC and

EFTA countries, as dened by ERC/REC 70-03 protocols

• About a WiFi portable devices the European standards dictate

maximum radiated transmit power of 100mW EIRP and frequency range

2.400÷2.4835GHz. In France these types of equipment must be restricted to

the 2.4465÷2.4835GHz frequency range and must be restricted to indoor use

USING THE REMOTE

UNIT SOLAR-02

GENERAL

5.1

The remote unit SOLAR-02 can be used in the following modes:

1. Independent operation without connection to any master instrument

for measuring in real time the values of irradiation, cell temperature and

environmental temperature on PV installations. To this purpose, the unit

accepts, as inputs:

For irradiation measurement (expressed in W/m2 - PYRA/CELL input):

• Solarimeter probe with thermobattery type Irr-P (see Table 1)

• Double reference silicon cell type  (see Table 1)

For module and environmental temperature measurement (expressed in °C – TEMP

input)

• Temperature probe type Tmp (see Table 1)

2. Operation for testing/recording synchronized with a master instrument for

measuring and saving irradiation and temperature values of cells:

• Connection via USB cable C2007 → Master instrument type M-USB (see

Table 1)

• Connection with radio frequency (RF) → Master instrument type M-RF (see

Table 1)

According with settings receveid by MASTER instrument, SOLAR-02 display a

Tc value:

• Measured by the temperature probe “Tmp” (see Table 1)

• Calcuted using NOCT (set in MASTER instrument), Irradiance and

Environment Temperature measured by SOLAR-02 according to relationship

where:

Tamb= Environment Temperature

Gp= Irradiance measured

NOCT= Normal Operating Cell Temperature

Tcel =Tenv + (NOCT - 20) x Gp

800

CAUTION

The presence of “K” symbol on the left of “Tc” temperature value, indicates

that the Cell temperature (Tc) value displayed is not a measured

value buti s a calculated value according with previous relationship.

When the SOLAR-02 is switched on (before connection to MASTER

instrument) the Tc value is the measured value.



In order to obtain correct irradiation measurement results, it is necessary to carry

out a correct preliminary setting of the sensitivity values of the probes connected

to the PYRA/CELL input of the unit. The set values will be read and considered by

the master instruments upon testing/recording and will be kept by the SOLAR-02

even when the unit is turned o, until they are modied.

The unit SOLAR-02 allows setting the parameters of max 3 irradiation sensors.

In detail:

• The use of a sensor type  requires setting the sensitivity (K) expressed in

mV/kW*m or in µV/W*m and the parameter Alpha expressed in %/°C for the

various types of silicon (monocrystalline, polycristalline, etc.)

• The use of a sensor type Irr-P → requires setting the sensitivity (K) expressed

in mV/kW*m or in µV/W*m. The parameter Alpha expressed in %/°C is

ignored.V/W*m-2. The parameter Alpha expressed in %/°C is ignored.
