Are solar availability assumptions too optimistic?

Views from NREL, DNV and kWh Analytics

When:

Thursday, February 1, 2024 2:00 PM - 3:00 PM EST

Solar Availability is generally a controllable loss, but yet there can be material losses. This webinar will present three recent studies on this topic from three different organizations: NREL, kWh Analytics and DNV to describe what availability losses are realistically achievable. Variations in these values by plant size and other characteristics will be described.

The webinar is intended for solar developers, financiers, manufacturers, and asset managers. After the webinar, attendees will have answers to the following questions:

  • What will DNV’s new availability loss assumption be?
  • What type of data went into determining this new availability loss?
  • How does DNV’s analysis compare with NREL and kWh Analytics?

Usgal Zandanbal, Manager, Solar Energy Assessment, DNV (moderator)

Usgal Zandanbal is an energy engineer with 5+ years of solar energy assessments experience, including PV only and PV+Storage, third party reviews as well as operational assessment experience in utility scale, C&I, and complex terrain projects in North America and other regions. She has worked on 11+ GW of energy estimates directly plus more in support and also assisted on validations within her time at DNV. Previously, she had worked for a solar developer assisting in site identification efforts in multiple utility regions across the U.S., provided GIS assistance for projects 100MW and up, and completed various market researches. Usgal has a Bachelor of Science in Energy Engineering from the Pennsylvania State University with a minor in Environmental Engineering.

Ben Browne, Data Scientist, kWh Analytics

Ben Browne is a data scientist with 18 years experience in solar and adjacent technologies, most recently as lead data scientist at kWh Analytics responsible for the physical and machine learning modeling behind the solar production guarantee “the Solar Revenue Put”. Ben has an academic background in semiconductor physics. He spent his PhD and postdoc designing innovative solar cells for concentrator photovoltaics. He then joined JDS Uniphase to commercialize the technology, which culminated in the release of a solar cell to the market with a record median efficiency above 41%. Prior to joining kWh Analytics Ben worked at Philips Lumileds designing, characterizing and reliability testing LED chips for low energy lighting applications.

20240201 Ian Tse 200x200p

Ian Tse, Senior Solar Engineer & Software Developer, Energy Analytics & Measurements, DNV

Ian Tse is a senior solar engineer and software developer at DNV. Ian has been involved in PV system performance modeling and risk assessment since 2015. He has years of experience working with operational data from PV plants, using them to evaluate performance, estimate future generation and help clients salvage recoverable losses. Ian is also a developer for several digital products at DNV that offer solar data and energy simulation services. Prior to DNV, Ian worked as director of analytics at a solar startup. He has a Ph.D from UC Berkeley and a BS from Cornell University. Outside of work, Ian enjoys hiking, traveling, volunteering and spending time with family.
