IEA PVPS Task 16

Solar resource for high penetration and large

scale applications



Background of PVPS Task 16

• International Energy Agency (IEA)

Technology Collaboration Programmes (TCP)

used as backing organization

• Formalised way of international collaboration

• Participants are confirmed by states

• Three solar programmes involved:

• Solar Heating and Cooling (SHC)

• SolarPACES (solar chemistry and

concentrating solar power)

• PV power systems (PVPS)

• Duration: 2017-2020 (extented to 2023)



IEA SHC Task 36/46

• 2005 – 2016, lead by Dave Renne (NREL, ISES)

• Best Practices Handbook for the Collection and Use of Solar Resource Data

for Solar Energy Applications (2015)

http://www.nrel.gov/docs/fy15osti/63112.pdf

• New version 2018

Best Practices Handbook for the Collection and Use of Solar Resource Data

for Solar Energy Applications: Second Edition

https://www.nrel.gov/docs/fy18osti/68886.pdf

• Benchmarks:

– Satellite based solar resource assessment

– Solar forecasts

• Modelling:

– Definition of circumsolar radiation and DNI

– Integration of ground measurements with model derived data

– Spatio-temporal variability of solar resource with respect time and space aggregation

Objectives for the Task 16 of PVPSBig PV and high penetration need high quality of meteorological

information

• Finer spatial and temporal resolution of data

• Uncertainty in solar belt still high

• Resource uncertainty is biggest part of financial uncertainty

• Main objective:

Lower solar resource uncertainties to lower costs of

implementation

• Added values

• Independent benchmarks

Never trust non independent validations

• Scientific exchange

Faster and more detailed as on conferences
