3rd Task Meeting in Sweden
June 2006
The 3rd Task meeting was held in Sweden, 1-2 June 2006, hosted by
Lund University.
The status for the different subtasks is listed in the following.
Subtask A - Market and Commercialisation:
A compilation of several existing market surveys regarding PV, Solar
Thermal and PV/T has been drafted to the Task experts. At the same time
a document dealing with the planning of a market survey (A1-3) within
the framework of IEA SHC Task 35 has been initiated.
An overview of commercially available PV/T collectors has been drafted
to the experts and when the document is completed it will be made
available at the public website. The document will be updated every half
year.
The drawing up of a document dealing with identification of key
persons/groups in the PV/T market is on-going.
A review of the deliverable D3-5: PV-Thermal systems marketing and R&D
roadmap from the EU-project PVTF, which is part of the cluster project
PV Catapult, has been initiated. The Task experts have here been asked
to provide input to whether the conclusions in the deliverable are valid
for their respective countries.
Subtask B - Energy analysis and modelling:
The preparation of the deliverable DB1: Report on heat transfer
models and electrical performance of PV/Thermal Solar Systems has been
started. Here an investigation of already available simulation models,
TRNSYS components and theoretical models is being described and the
document will be relevant to all experts interested in starting
modelling PV/Thermal Solar Systems.
Subtask C - Product and system development, test and evaluation:
Categorisation of PV/T collectors has been initiated and the overview
of PV/T collectors and projects initiated by IEA PVPS Task 7, activity
2.5 and continued by the IEA SHC PVPS Joint Working Group on PV/Thermal
Solar Systems has been updated.
Investigation of the needs for development of PV/T-systems, -components
and -control strategies has been performed by asking industry,
manufacturers and designers. Only few answers have been received and
therefore mainly the experience from the participating Task experts will
be used in the further work in this area.
Important input has been provided to the PV Catapult deliverable D8-6:
PVT performance measurement guidelines and the document deals with
performance testing issues for liquid cooled non-concentrating PV/T
collectors. From this work it will be possible to characterise a PV/T
collector in such a way that the annual energy production, both thermal
and electrical, can be predicted for any given site.
It was the idea to let a number of PV/T collectors be tested at various
laboratories from March 2006 an onwards in order to achieve a much
better understanding of the performance of already existing systems. For
various reasons these tests have not been carried out yet.
Subtask D - Demonstration projects:
Interviews with stakeholders for already realized PV/T projects have
been planned and are now being initiated on a national basis. The
interviews will be used to give general recommendations on future
demonstration projects and will also give information of whether
monitoring results are available or/and whether it is possible to
monitor in the context of Task 35.
There are also activities focusing on the identification and initiation
of new demonstration projects allowing for monitoring and comparison
with simulated performance of the systems in accordance with the
findings in the Task. An advertisement will be made at the official Task
website to help locating suitable host(s) for demonstration of a
particular PV/T technology or -system.
Subtask E - Dissemination:
An article presenting an overview of PV/Thermal Solar Systems and the
research work IEA SHC Task 35 has been drawn up in the middle of April
2006 for the Austrian journal "erneuerbare energie". The journal reports
about research and development in the field of renewable energies and
the article will be published in the next edition of the journal.
The official Task website
http://www.iea-shc.org/task35 is continuously being updated
and in April 2006 the website has been renewed and undergone graphical
changes in order to be more attractive and professionally looking.
