Module integrated energy saving inverter


In photovoltaic power for 230 volts applications, the inverter is the key component but one of the majo obstacles are that the present inverter technology is ineffective, and expensive. The problem with the low inverter efficiency is, that typically 10 to 15% of the energy produced by the photovoltaic panels is wasted. The investments in photovoltaic panels is, correspondingly, 10 to 15% higher than actually required. In continuation of present RTD experience of the consortium with inverter technology, we therefore propose to develop an inverter with a completely new technical principle, which ensures an efficiency better than 98% at low cost. The new inverter principle will be a break with the conventional principle which includes bulky and expensive transformer- and filter components, primarily using copper. The copper will be replaced by inexpensive silicon based components, enabled by the implementation of our proposed new module-based stair step concept. To develop the new high efficiency photovoltaic system, the following tasks are needed: Concept evaluation, and optimisation. Specification of photovoltaic, battery, inverter and interfaces Cost and efficiency evaluation of the photovoltaic system, compared with the present standard. Market aspects and opportunities must be implemented in the research.
