The developer of PVsyst, André Mermoud wrote to me in response to my recent post: Backtracking Issues in PVsyst. He pointed out that my description of the problem we not entirely correct. I encouraged him to document the issue on his website so that users have accurate information when using PVsyst to simulate tracking PV systems. …Details
Lauren Ngan et al. from First Solar presented a great poster at the 39th IEEE PV Specialists Conference in Tampa, FL on how “true” single axis tracking (without backtracking) produced more energy for First Solar arrays than the use of backtracking, which avoids row-to-row shading. As part of her study, she and her coauthors discovered…Details
The NREL Sysytem Advisor Model is holding the SAM Virtual Conference on the July 23rd. The deadline for submitting an abstract to present is next Tuesday, June 11. If you would like to make a presentation, please visit the conference website for abstract submission instructions. (You do not need to submit an abstract or pre-register to be a…Details
The New York Times published an interesting article about module reliability and degredation problems, quoting several PVPMC members. The article can be seen here: http://nyti.ms/16nXR7p. One interesting and relevant fact cited is a study by Meteocontrol of 30,000 PV systems in Europe, which found that 80% of these systems are underperforming expectations. This finding indicates to…Details

The 2nd PV Performance Modeling Workshop was held on May 1-2 in Santa Clara, CA. The event was well attended with about 150 attendees from North America and Europe and the feedback we received has been very positive. Workshop attendees learned about advances in in PV performance models and modeling practice from industry experts (late…Details
IEA Task 13 Workshop on “Lessons Learned from the Analytical Monitoring and Modeling of PV Systems” June 16, Tampa, FL
The International Energy Agency’s Task 13 (Photovoltaic Power Systems) will present a workshop in conjunction with the 39th IEEE PV Specialists Conference in Tampa, FL on Sunday June 16 from 1 – 5 PM at the Tampa Convention Center. The workshop is called “Lessons Learned from the Analytical Monitoring and Modeling of PV Systems” Summary: …Details
There has been lots of interest in this workshop and we have just expanded the number of registration slots for this workshop to beyond 110! If you have not registered yet, please do so ASAP at this site (http://pvworkshops.sandia.gov).
The 2nd PV Performance Modeling Workshop is going to be held May 1-2 in Santa Clara, CA as part of the 2013 PV Systems Symposium being sponsored by Sandia National Laboratories and Electrical Power Research Institute. Registration is available here. Draft agenda is also available for download.
The wide variety of PV system technologies and designs, site conditions, and operations strategies means that complex PV system performance models are needed to represent PV plant performance. While PV component and system costs are rapidly falling, the upfront costs of PV (before any energy is generated) remain high. Sandia National Laboratories’ scientists, Joshua Stein…Details
