  • Page 15: Installation And Commissioning

    7 Installation and commissioning 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.

  • Page 16: Installation For Measuring Global Radiation

    7.2.3 Installation for measuring global radiation 7.2.3.1 Choosing a site There should be no obstructions to the field of vision above the instrument’s sensor element. If this is not possible, the location of the instrument must be chosen to ensure that obstacles do not rise by more than 5 degrees above the azimuth range between sunrise after the shortest night and sunset on the longest day.

    7.2.5 Installation for measuring reflected radiation In inverted position the pyranometer measures the reflected global radiation. Mounting plate Pyranometer Glare screen Mast (black) 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.
