Application of PVT Collectors

PVT Systems: Application of PVT Collectors and New Solutions in HVAC Systems

Task 60 - PVT SystemsThis Task will focus on the application of PVT collectors with the aim to assess existing solutions and to develop new system solution principles in which the PVT technology really offers advantages over the classical “side by side installations” of solar thermal collectors and PV modules. Energy  production, competitive cost, safety and reliability of systems are therefore in the scope of the Task. The objectives of the Task are to: 

  1. Provide an overview on the present (2018-2020) state-of-theart of the PVT technology worldwide.
  2. Gather the results and the operating experience made with the systems in which PVT collectors are integrated. 
  3. Improve the testing, modeling and adequate technical characterization of PVT collectors in order to enhance (and simplify) the correct inclusion of the PVT technology in simulation programs and planning tools. 
  4. Address all types of PVT collectors since the current markets have made no clear choices.
  5. Find more typical PVT solutions beside the two applications which are well known, i. e. regeneration of bore-hole storages and pre-heating of DHW for multi-family houses.
  6. Explore potential cost reductions in the balance of systems, i.e. piping technology and materials, hydraulics, controls etc.
  7. Increase awareness of PVT. 
  8. Support the re-start of the PVT industry

What's New
  • A top scientific paper from Maria Herrando and al. on PVT collector optimal design - The paper is published in Science Direct: Herrando M, Ramos A, Zabalza I, Markides CN. A comprehensive assessment of alternative absorber-exchanger designs for hybrid PVT-water collectors. Appl Energy 2019;235:1583–1602. doi:10.1016/j.apenergy.2018.11.024 The paper deals with the design and optimisation of a PVT collector, and addreses: A 3-D FEM and CFD model to simulate a hybrid PV-Thermal collector (PVT) is developed. Several flat-box designs and materials for the absorber-exchanger are studied. Flow-channel size or material seem not critical within the range of investigation. Polymeric flat-box designs are expected to suffer lower strains than sheet and tube units. Weight and investment cost reductions are achieved with polymeric PVT designs. (Posted: 2019-01-20)
  • PVT in South Africa (Posted: 2018-12-12)
  • PVT and seasonal storage: innovative technologies in Spain - Local production of PVT panels and systems which achieve high solar fractions by using seasonal storage: This is the main objective of Spanish start-up company Abora, based in Saragossa. It has already installed several hot water PVT systems at multi-family houses, sports centres and nursing homes and a combined heating and cooling unit at a hotel in Gerona in the northeast of Spain.
