New pv system technology

Objective



The objective of this project is to develop a highly innovative PV system concept (NST) which aims at removing the major weaknesses of state-of-the-art PV system technology such as
- Varying lifetime expectancy of PV system components
- Low degree of integration of electronic components
- Sensitivity against shading
- High cabling cost
- Significant mismatch losses
To overcome this situation high-level European PV system companies, amongst the the leading European PV module manufacturer, have joined their R&D efforts in a common industrial project aiming at the detailed development of this innovative PV system concept, the development, manufacture and test of NST component prototypes and the installation and monitoring of a NST pilot plant. In detail the industrial benefits are:
l.A lifetime of balance of system components (in particular power transmissionand power conditioning equipment) matching the PV module lifetime (>25 years) 2.A Mean Time Between Failures MTBF of electronic equipment of > 100.000 hours 3.Highest integration of electronic circuits (ideally leading to the"one-chipinverter")
4.Miniaturisation of electronic components due to magnetically induced energytransmission and conversion
5.Avoidance of mechano-electrical module connections (using magneticallyinduced coupling instead)
At the end of project duration the industrial achievements of this extensive hardware development project will be as follows:
- Tested and approved prototype of an innovative Magnetically Induced Power Bus (MIPB) Technology with fully integrated Magnet Power Receiver (MPR) for energy transmission from the PV module to the Power Bus. This technology will lead to higher system efficiency and reduced safety needs due to hermetical isolation of NST components. Patents will be applied for.
- Tested and approved prototypes of innovative PV modules with fully integrated Magnetic Power Transmitter (MPT). Patents will be applied for.
- Tested and approved prototype of Magnet Power Receiver (MPR) for contact free magnetically induced coupling of the PV modules to the electric circuit. Patents will be applied for.
- Tested and approved Central Power Processor (CPP) which links the NST system to the public grid and which performs the overall system control. Patents will be applied for.
- Approved NST concept in a PV pilot plant realised at the facilities of one of the project partners It is expected that after the end of the project about 1.5 year of additional research, testing and demonstration of the products will be required to make the New PV System Technology fully reliable. This time will be used for patent disclosures, for preparing the products for market introduction and for licensing negotiations with interested European companies aiming at a rapid and widespread dissemination of this technoloqy. The full commercial exploitation of NST will start at this moment.
