This is to simulate the sun striking the [[photovoltaic]] panels at seven different angles. This data will be used to better understand the spectral effects on PV, but also to optimize system and device design for a specific geographic location.\n\n== Background ==\n\nThis project was started by the [[Queens Applied Sustainability Group]] over the summer of 2011. On Wednesday April 11/12 Roger Gauthier & Quinn Bentley from SEARC assumed control of managing the equipment from Rob Andrews. [[SEARC]], [[QAS]], [[MOST]] and UBP are all collaborating on this project.\n\n== Equipment ==\n\n'''Software'''\n\nAvasoft Ver. 7.5.3\nArduino Uno Ver. 1.0\n\n'''Hardware'''\n\n– Avantes NIR (near infrared fibre optic) Spectrometer\n\nAVS-Rackmount-USB2: 19\" Rackmount for USB2 platform multichannel AvaSpec, incl. channel synchronization, USB2-hub and 100 – 240 VAC power supply, supports max. 10 rackmount unit spectrometer channels.\n\nUser: Avantes Inc.Date: 04-05-11\nChannel(s): 2 Software: Full, Irr\n\n'''Features:'''\n\nAvaSpec – USB2.0 platform – offers maximum modularity\nThe AvaSpec – USB2.0 platform offers maximum modularity for multi-channel applications. For each channel a different wavelength range, detector and integration time can be selected, without losing the advantage of synchronization between the different channels. The AvaSpec – USB2.0 platform uses the USB2.0 bus to connect the different channels to the PC platform and supports up to 127 channels. Applications that can be realized with the AvaSpec – USB2.0 multi – channel platform:\n\n* Different integration times or averaging settings per channel, still start each scan simultaneously for all synchronized channels\n* Different detector types, such as UV/VIS and NIR detectors possible to cover a wide wavelength range with one spectrometer system\n* More than 8 channels (even up to 127 channels) can be connected through USB2 hubs.\n\n2 X Spectrometer Detectors\n\nSony-ILX554\tSer#1105019U2\tGrating – (UA) -\t\t Sensitivity - From 200 to 1100 nm\n\nHam92XX\t\t\tSer#1105020U2\tGrating – (NIR100 – 2.5) - Sensitivity - From 1030 to 2500 nm\n\n'''Inputs:'''\n\nAC Power – 120 VAC / 60 Hz / 16VA\nFuse T1A/250V (2 X Slow Blow)\n\n'''Outputs:'''\n\nUSB to Computer\n26 Pin D-Connector to Arduino Uno/Motor Apparatus\n \n'''Start Up Procedure:'''\n\n* Turn on the main power button on the Avantes NIR Spectrometer.\n* Start the Avasoft Software Ver. 7.5.3\n* File --->Start New Experiment--->\n\n== See also ==\n\n* [[The effect of spectral albedo on amorphous silicon and crystalline silicon solar photovoltaic device performance]]\n* [[Spectral effects on amorphous silicon photovoltaic cells literature review]]\n* [[Effects of spectral albedo on photovoltaic devices]]\n* [[Solar resource measurement for PV applications]]\n* [[Effects of spectral albedo on solar photovoltaic devices]]\n\n{{Page data\n| license = CC-BY-SA-3.0\n}}\n\n[[Category:Queens Applied Sustainability Group Lab Protocols]]\n[[Category:MOST methods]]\n[[Category:SEARC]]"}
