Page 13: Installation
7 Installation 7.1 Planning installation For the solar irradiation to be measured in the entire photovoltaic system, it is necessary to position several pyranometers in the system. The number of pyranometers required depends on the system’s performance and ambient conditions. The minimum number of sensors required for a Class A system is defined as follows: –... - Page 14 The 5 degrees correspond to a minimum distance from the instrument to the obstacle of 10 times the height of the obstacle: >10 x h Minimum distance from instrument to obstacle The minimum distance is important for measuring the direct radiation. The diffuse solar radiation is not so affected by obstacles near the horizon.

4 Position the instrument in such a way that the nuts are located at a distance of 2 to 3 mm from the mounting device. 4 Ensure that the instrument is grounded. 4 Ensure that the instrument is not in the shade. 4 When installed horizontally, point the cable connector towards the nearest pole to reduce the UV exposure on the cable. -
Page 16: Installation For Measuring Reflected Radiation
7.2.5 Installation for measuring reflected radiation In inverted position the pyranometer measures the reflected global radiation. Mounting plate Pyranometer Glare screen Mast Equator The mounting plate prevents the pyranometer from being heated by solar radiation. The optional glare screen has an angle of 5 degrees and prevents direct radiation on the glass dome during sunrise and sunset. -
Page 17: Installation For Measuring Diffuse Radiation
7.2.7 Installation for measuring diffuse radiation For the diffuse radiation to be measured, the direct radiation on the pyranometer’s glass dome must be blocked. The direct radiation can be blocked using a static shadow ring or a two-axis automatic sun tracker. Shadow ring Pyranometer Mounting bracket... -
Page 18: Electrical Installation
7.3 Electrical installation 7.3.1 Electrical connections SMP pyranometers are supplied with a waterproof connector pre-wired to 10 m of high quality yellow cable with 8 wires and a shield covered with a black sleeve. Long cables may be used if the cable resistance is less than 0.1 % of the impedance of the readout equipment for the analog outputs. -
Page 19: Analog Voltage Output
Typical power consumption SMP-A for max output (20 mA) Voltage on the pyranometer (V DC) Current (mA with 100 Ω load Power (mW) resistor) The above Megawatt values represent the dissipation within the SMP-A. For the total power the energy in the load resistor has to be added. -
Page 20: Connecting To Computer
7.3.7 Connecting to computer NOTICE Damage due to lack of insulation! The power supply units of portable computers such as laptops can generate large voltage peaks. This may cause damage to the instrument’s digital interface. 4 Ensure that the converter has galvanic separation between the inputs and outputs. The instrument must be connected to a computer via an RS-485 converter with a USB port. -
