Efficient use of energy is the political, social, and technical challenge of the future. ERG is an ENIAC project in which a consortium of European partners joined forces to conduct research into a supply chain that would ensure the effective use of solar energy. The project encompasses the whole supply chain, including research into new solar cells, new architectures for energy harvesting, very high efficiency energy conversion, and the use of and connection to future smart grids.

The joint focus of the German project partners is on energy conversion in solar applications. This involves applying highly efficient semiconductor technologies in order to use the power from photovoltaic generators (CPV) with as little energy loss as possible. New energy converter architectures are being researched and tested with the goal of cutting losses by around 20 percent. Demonstrators will show the energy efficiency that has been achieved.

CPV Solar Tracker with an Intelligent Power Conversion System and Automatic Tracking

Concentrating photovoltaic (CPV) systems use individual, expensive chips that utilize a wider spectrum of sunlight. Many small lenses concentrate the sunlight onto the solar cell surface, which converts the sunlight directly into electrical current. For this reason, the solar modules have to be aligned exactly with the sun at all times of the day. Because even small deviations greatly impair efficiency, the modules have to be repositioned using high-precision trackers.

The advantage is that because the sunlight is concentrated, only a fraction of the active solar cell surface is needed compared to conventional solar modules. At the same time, CPV solar cells attain levels of efficiency of up to 40 percent, which is significantly higher than the levels achieved by other systems. Unlike flat solar modules, CPV modules have a very narrow acceptance angle for incident sunlight. Even small deviations have a big effect on power generation. As a result, they have to be aligned exactly with the sun at all times using high-precision trackers.

Structure of the Solar Tracker

In a field trial, a solar tracker will be installed for testing along with 24 solar modules over a total area of roughly ten square meters. Thanks to the innovative new tracking technology, the solar modules will be operated with maximum efficiency, and the foundation will be laid for research into further optimization measures.
