2nd Task Meeting in the Netherlands
October 2005
The 2nd Task meeting was held in The Netherlands 13-15 October 2005,
hosted by ECN. The meeting was organised as a two and a half day meeting
to allow sufficient time to co-ordinate the details of the planned
laboratory experiments and have updated presentations of on-going work
relevant to the development of PV/Thermal Solar Systems.
The status for the different subtasks is listed in the following.
Subtask A - Market and Commercialisation:
Important input to the task work has been provided from the
EU-project PVTF which is part of the cluster project PVCatapult. Here a
main deliverable is an overall road-map for commercialisation of PV/T.
The focus of the EU-funded work is naturally with the focus on the
European situation, but the methodology of the project and reporting
structure is very helpful as starting point for the work in Subtask A,
where also countries and design aspects outside Europe will be covered.
Specific activities have been started regarding the investigation of the
market. Principles for segmentation of the market has been developed for
both the PV and the solar thermal market and these analyses will be used
as starting point for the further investigation of the market for
PV/Thermal Solar Systems.
Subtask B - Energy analysis and modelling:
The investigation of already available simulation models, TRNSYS
components and theoretical models is being carried out. The overview
will be reported in a separate document relevant to all experts
interested in starting modelling PV/Thermal Solar Systems.
The modelling activities of the task have been started and an
interesting issue for this development is current research on parameters
determing the radiation balance and combination of absorbing and
transmitting layers of typical solar cells and the possibilties to vary
these properties. In popular terms this work could lead to solar cells
optimised for PV/Thermal Solar Systems, where all radiation, which can
be utilised for electricity production, is absorbed by the solar cell
and the same solar cell can be transparent to all other wavelengths, so
that the part of radiation not generating electricity will pass the
solar cell and can be absorbed by a thermal absorber under the solar
cell.
Subtask C - Product and system development, test and evaluation:
In order to achieve a much better understanding of the performance of
already existing systems, a number of products and systems relevant for
testing has been identified, and will be made available for testing at
various laboratories during the first half of 2006.
The first round of testing methodology has been discussed and decided at
the 2nd task meeting in The Netherlands. An issue on round-robin tests
versus testing according to current norms and standards was discussed at
the last task meeting. It was decided to have the round-robin test when
sufficient knowledge regarding characterisation of the performance of
the different types of systems has been established, however until then
different test methodologies based on the experiences from the
participating laboratories and most recent international standardisation
of testing procedures of solar systems will be used to achieve the first
level of understanding of the performance of the systems.
Subtask D - Demonstration projects:
In order to be able to gain knowledge from demonstration projects
within the time schedule of the task, the planning of work in subtask D
is focusing on the identification of potential projects to be realised
during 2006, allowing for monitoring of the realised projects and
comparison with simulated performance of the systems.
Currently several PV/Thermal Solar Systems are being planned in The
Netherlands, South Korea, Canada and Israel. Details on these projects
are being collected and analysed and decision on which projects to
assist regarding design, monitoring and dissemination will be decided at
the next task meeting in first half of 2006.
Main activities of this subtask in the reporting period focus on
establishing contact to potential hosts of demonstration projects and
provide understanding of the needs and possibilities of the host and the
specific objective of the demonstration project in each case.
Subtask E - Dissemination:
A good brainstorm session on dissemination activities at the 2nd task
meeting has resulted in several ideas on how to disseminate the results
of the task and how to learn from the dialogue with the key stake
holders regarding key design criteria, key performance indicators
relevant to focus on in order to target the market and input regarding
spedific need for building integration of the technology into various
types of building and architectural styles.
Among the ideas is much better use of the IEA stand at upcoming
conferences, where it could be interesting to exhibit a standard PV, a
standard Solar Thermal and a PV/Thermal Solar system and ask interested
visitors of the stand about their immediate impression and what they
would expect of the combined system if they should consider it as an
alternative to traditional systems.
Other activities of this subtask focus on the development of
presentation templates (MS PowerPoint) to be available for task experts
to ease the presentation of the task in general, the participating
experts, ongoing and completed activities and scientific material in
general regarding PV/Thermal Solar Systems.
