review news EU rooftop’s to provide 40% demand
The European Photovoltaic Industry Association (EPIA) together with Design- Build Solar has organized an event on Building Integrated Photovoltaic (BIPV) systems, at the premises of the Ministry of housing in Madrid, in the framework of the “Solar Decathlon”. The event will count more than 170 participants representing mainly architects, installers, representatives from the renewable and construction industries. The speakers, coming from all around Europe, will address the latest technological and market trends within this sector as well as the economic and regulatory frameworks in Spain and within the main European PV markets.
With a total ground floor area over 22,000 km2, 40% of all building roofs and 15% of all facades in EU 27 are suited for PV applications. This means that over 1,500 GWp of PV could technically be installed in Europe which would generate annually about 1,400TWh, representing 40% of the total electricity demand by 2020.
The integration of photovoltaic energy in buildings provides an enormous development potential for the PV industry as well as for the construction sector.PV applications, apart from contributing to the generation of electricity and improving the passive energy behaviour of buildings, can replace conventional building components and also provide different functions such as, water tightening, weather protection, heat insulation, light modifications, etc.
“Spain has a unique opportunity to develop the BIPV market, which in addition to
leveraging the decentralised nature of PV generation, energy generated by the citizen for the citizen, would enable the stimulation of tens of thousands of jobs firmly anchored in the local economy, many of which in the construction industry”, said Virgilio Navarro, EPIA’s Vice-president and CEO of ATERSA.
Currently in some European countries the BIPV market is driven by specific support schemes, designed in such a way that BIPV systems are rewarded with a higher tariff per kWh generated than for Building
Adapted PV (BAPV), where the PV modules are installed on top of the existing building structure and do not provide any additional function. This acknowledges the added effort and extra cost of integrating PV as part of the building envelope. It is in particular the case in France and Italy where BIPV already represents over one third of the annual market. In other countries such as Germany and Spain, where support schemes are not differentiated between both types of systems, BIPV only represents a very marginal share of the market.
RFMD unveils its latest versatile front end module
The highly integrated, single-chip RF3858 supports multiple Tx/Rx applications in the 900 MHz ISM band, including Smart Energy/Advanced Metering Infrastructure (AMI).
RF Micro Devices a global provider of high- performance radio frequency components and compound semiconductor technologies, has announced the availability of the RF3858 front end module (FEM). The RF3858 FEM supports multiple Tx/Rx applications in the 900 MHz ISM band,
including Smart Energy/Advanced Metering Infrastructure (AMI).
The highly integrated, single-chip RF3858 addresses the increasing requirements for aggressive size reductions in the RF front end designs for portable equipment.
The RF3858 combines a 1-watt 915 MHz power amplifier capable of 31.5 dBm of output power, with a double-pole double- throw (DPDT) Tx/Rx transfer switch with low insertion loss and high isolation, a low noise
amplifier (LNA) with bypass mode, and a Tx harmonic filter.
The RF3858 reduces the number of external components by approximately 80% versus discrete designs, greatly minimizing product footprint, accelerating design-in time and reducing overall assembly costs. The RF3858 is packaged in a small 8.0 mm x 8.0 mm x 1.2 mm over-molded laminate package with backside ground, minimizing next level board space and allowing for simplified integration.
