OPVT – Hybrid solar collector (PVT) in polymer materials

OPVT is a German R&D project, on which Aventa collaborates. The objective of the project is to develop a hybrid solar collector composed of an organic PV component and a polymeric solar thermal component for the cost competitive, renewable energy production of both heat and electricity. The collectors will be designed as building-integrated solar envelope modules in order to meet future energy scenarios, which are directed towards zero energy or plus energy buildings. Tomorrow’s building skins have to be transformed to multi-functional roofs and facades producing heat (cooling) and electric power.

Solar collector installation in progress at Ilseng Prison

Statsbygg* is looking to utilize solar energy. This summer, the agency signed a contract with Aventa for the delivery of a new solar heating system to Hedmark prison, Ilseng Deparment, in Hamar. Installation of 270 square metres of solar collectors that will contribute to the supply of domestic hot water commenced this week. Roof tiles are removed from the south-facing roof of the barracks and replaced with solar collectors. The total heat store volume is 8 400 litres. According to schedule, the installation should be completed by mid- December.

The MOS is one of the largest and most important trade fair events in Slovenia with 1,500 exhibitors from 35 countries and more than 125,000 visitors. A new feature this year was the Crossroads of Science and Economy element, supported by the Ministry of Education, Science and Sports. This special part of the exhibition promoted cutting-edge technologies and new technological innovations and processes. The National Institute of Chemistry in Ljubljana was one of several scientific institutions present at the stand. The institute has developed a special type of color painting – TISS coatings – that will improve both the efficiency and aesthetics of solar collectors. The NorDan Solar concept with solar collectors integrated in traditional window frames was used to illustrate state-of-the-art solar collector solutions.

Aventa recently visited the German research institute for solar energy – Fraunhofer ISE, in Freiburg – where our solar collectors have been a part of the experimental set-up  for several years. The solar collectors are primarily undergoing accelerated aging tests, which will determine their lifespan under various conditions. Ad hoc testing of the collectors is also being carried as part of our product development programme.

Planning of pilot projects was on the agenda when the partners in the Nordic Built project “Active Roofs and Facades in Sustainable Renovation” met in Malmö recently. The goal is to show solutions for sustainable renovation that can be integrated in existing buildings, with regards to architecture, comfort and energy efficiency. The Aventa technology will be used at a demo-site at the Technological Institute near Copenhagen, and at a CO2 neutral kindergarten In Copenhagen.

BioSol – 100% renewable heating

biosol-100-renewable-heating_articleimage

BioSol represents a new concept for heat transfer from a stove into a water-based heating system, which combines high efficiency and negligible risks. A solar system is directly coupled to the heating system. The energy demand for space heating and hot water preparation can thereby be 100% covered by renewable energy in terms of firewood and solar energy.

Aventa part of IEA-SHC Task 54 – Price Reduction of Solar Thermal Systems

aventa-part-of-iea-shc-task-54-price-reduction-of-solar-thermal-systems_articleimage

This Task aims to reduce the purchase price for end-users of installed solar thermal systems by evaluating and developing sustainable means to reduce production and/or installation costs of material, sub-component, system-component and system level. Special emphasis is placed on the identification and reduction of post-production cost drivers. Moreover, ways to make solar thermal more attractive by improved marketing and consumer-oriented design will be explored.
