Obiettivo Objectives and problems to be solved: Potential exists for the delivered energy from solar photovoltaic (PV) plant to be increased by between 10% and 25% compared to converters currently available and depending on the region in which they are deployed. Experience has shown that the unconverted energy of currently implemented PV systems is a considerable proportion of the total energy available, especially in winter time or in the case of partial shading of the PV array. Description of the work: The project will be carried out in a two-year time span with the combined efforts of four qualified partners: SEI in Italy, ATERSA in Spain, CREST in UK and SUT in Slovakia. The project aim is the development and realisation of a new grid-connected inverter of Kew nominal power and having high efficiency (greater than 92%) between 2.5% and 100% of nominal power. The inverter is based on the philosophy of multiple converters, where several sections operate in parallel and are automatically matched to the actual power generated by the PV array. This enables an increase in the energy delivered to the grid in conditions of low solar radiation and also when the PV array is partially shaded. The project consists of six work tasks: 1. Design of the inverter - definition of electrical & mechanical design concepts, design detail, nominal voltage & power, MPPT algorithm, DSP software development, prototype development. 2. Value analysis - total value analysis, definition of cost sensitive inverter sections and cost reduction options. Regulations - up-dated for grid connection in Italy, Spain, UK and Slovak Republic's. Manufacture - 10 inverters of 2kW.5. Laboratory testing - complete electrical and mechanical test procedure for the inverters and lab tests. 6. Installation and field test - field installation of one complete system, complete monitoring procedure and system monitoring. Expected Results and Exploitation Plans: The new inverter will be particularly effective in building applications, where partial shading of the PV array will occur from time to time. Delivery of a greater proportion of available energy to the grid results in a considerable reduction in the total cost of energy production from the PV system. The structure of the proposed inverter design is highly innovative. New electronic digital components are used to reduce losses and improve price. The price target for the new inverter is less than 300 Euro/kW, considerably lower than the cost of PV inverters currently available.
