August 2021 update: We have a QEX10 system for sale!
PV Measurements (PVM) is not presently offering new reference cells, QE / IPCE / Spectral Response systems, cell I-V measurement systems, uniformity mappers, or spectroradiometers. However, we still strive to support almost all the products we have ever made. We also sell used equipment from time to time. PVM wishes to support its customers as they transition us all to solar energy.
Your first resource is the manual that was provided with the equipment. For further assistance with measurement techniques, repairs, modifications, data interpretation, noise reduction, and calibration, please visit our technical support forum using this link. PV Measurements monitors the forum and provides responses. Users can help each other resolve many issues.
PV Module Testers
PVM can offer module testers with unique features for some specialized applications. Please enquire by email using sales at our domain name.
PVM has a lightly used QEX10 QE / Spectral Response / IPCE Measurement System for sale! This system was originally built in 2012 and has seen minimal use as a demonstration system. Although it was not built recently, it is far from obsolete; many QEX10 systems and their predecessor system, the QEX7, are still in service, with scientific papers mentioning them being published almost every week. The system is available with short lead time and a substantial discount from its original selling price. If you’re in the market for a world-class QE system, please enquire.
The silicon calibration photodiodes provided with PVM QE systems have shown themselves to be stable for many years. However, it is still a good idea to have these recalibrated periodically. PVM can provide ISO 17025 and non-accredited calibration services on original or new silicon photodiodes.
IR photodiodes provided with PVM QE systems that have infrared range extensions might not be as stable as the silicon photodiodes. Thus, periodic recalibration of these devices may be even more important, depending on the application’s accuracy requirements. We can provide photodiode calibrations for some parts if IR extension spectral ranges.
PVM has a small number of test fixtures and other accessories for sale. Please enquire by email using sales at our domain name and tell us about your needs.
Replacement and Spare Parts
Many components that cannot be repaired can be replaced. Many parts are still available. In some cases, PV Measurements can offer used and/or refurbished components. Please enquire by email using sales at our domain name.
Replacement and Spare Lamps
Almost all lamps used in PVM products are available from vendors found on the internet. We recommend that users purchase only from vendors capable of assuring that lamps are genuine products manufactured by the same companies that made the original lamps. PVM has had bad experiences with counterfeit, “compatible”, and “replacement for” lamps.
We expect to resume offering on-site training in North America once it’s safe to travel without risk of spreading SARS-CoV-2. Please enquire by email using sales at our domain name. For training outside of North America, please contact the distributor or trading agent that supplied the equipment. If there wasn’t one, or if that party is unable to help, please contact us.
We can repair many components of I-V and QE systems that built by us. Please enquire by email using “sales” at our domain name.
