    PV spectral correction factors for up to nine difference PV panels. This SolarSIM-GPV’s data can be used within any standard PV modelling software to quantify and account for the effects of solar spectral variation on PV performance.

  • Page 6: Main Components

    1 Main components A side view of the SolarSIM-GPV’s primary components is shown in Figure 1, which include: • a glass dome, • an enclosure, • bandpass filters, • bubble level, • a connector, and • a backplate. Figure 1: SolarSIM-GPV components and main dimensions.

  • Page 7: Glass Dome

    1.3 Bandpass filters Nine bandpass filters transmit a narrow band of spectral irradiance to the detectors. 1.4 Bubble level The bubble level ensures the SolarSIM-GPV is leveled when measuring the irradiance in global horizontal orientation. 1.5 Connector The connector provides power and communication to the SolarSIM-GPV electronics.

  • Page 8: Installation

    2.2 Mechanical installation Installation of the SolarSIM-GPV consists of fastening it to a mounting plate using three M4 screws and springs, as demonstrated in Figure 2. The mounting plate can then be mounted to a pole or table as required. The mounting plate is 7.3 mm thick and has three slots with a 132 mm diameter that are 4.5 mm wide for external fastening, as shown in Figure 3.

  • Page 9: Maintenance

    The SolarSIM-GPV requires very little maintenance. The primary concern is to ensure that the glass dome of the SolarSIM-GPV is clean at all times, as the accumulation of dirt can lead to underreported and inaccurate data. Spectrafy’s GV-1 ventilator can aid in this.

  • Page 11: Connectivity

    4 Connectivity The SolarSIM-GPV uses the iSG Integrated Spectrum Generator add-on to automatically process it’s raw data and output global solar irradiance (GHI/GTI/POAI) and PV spec- tral correction factors directly to a datalogger over RS-485 modbus. The iSG consists of a 150x100x50mm, IP66 rated aluminium enclosure that can be deployed in open air, or within a datalogger enclosure, where it mounts by standard DIN rail.

  • Page 12: Data Outputs

    The SolarSIM-GPV uses Spectrafy’s innovative multispectral measurement approach to ac- curately resolve the global solar spectrum over the 280-4000nm wavelength range. From this spectral irradiance data, the SolarSIM-GPV outputs the global irradiance (calculated from the wavelength integral of the spectral irradiance) and PV spectral correction factors (SCF) for up to nine different PV panels.

    5.1 Data outputs The SolarSIM-GPV+iSG, outputs data as detailed in Table 1 below. Table 1: SolarSIM-GPV data outputs Parameter Name Units Notes TimeStamp Local timestamp G Irradiance Global irradiance GHI/GTI (Class A) G SCF 1 Spectral corr. factor 1 First Solar S3+ G SCF 2 Spectral corr.

  • Page 14: User Defined Spectral Response Curves

    The SolarSIM-GPV comes with nine default spectral response (SR) curves as detailed in Ta- ble 5. The SolarSIM-GPV can also be used with user-defined SR curves. If you would like to use alternative SR curves, please contact us at info@spectrafy.com before your SolarSIM-GPV unit is shipped, so that your SR curves can be incorporated into the software.
