Research and development are central themes for the Bavarian J.v.G Thoma GmbH. Funds for another highly interesting research project of bewi Freystadt/Oberpfalz – were now ever more, the Sun seems better for the extraction of solar energy, the industry leader in the construction of turnkey solar plants. Might you think. However, the whole thing has a hook: rising temperatures, namely, continuously decreases the performance of the solar modules. Expressed in figures: A plus on the thermometer means a drop of 0.5%. This is due to a special property of Silicon. The temperature in a module can rise quite to 70 C on a hot summer day.

How can we counteract this effectively? That is the question, which is now the research team of J.v.G Thoma on the agenda. The basic idea: the temperature in the modules to approximately 20 C can be cool, so this means a power increase of 20%; When compared to the performance at 60 C. And in the annual average. The ground as a buffer? Answers wanted on a fundamental problem! Indeed, there are promising starting points: at a depth of about three meters, a temperature of 10 C prevails throughout the year. Our goal is to use the ground as a heat sink”, explains Dr.

Claudia Gemmel, Director of R & D at J.v.G. Thoma. The excess heat is emitted through lines to the ground. This is a basic problem, which is now to be solved in the framework of the research project but: the soil has poor thermal conductivity. Cooling loads of > 4 W / m2 there is a build-up of heat in the immediate vicinity. Thus the heat prevents the cooling circuit to the ground.” But also the researchers of J.v.G Thoma have found already a promising approach, Dr. Claudia Gemmel using the approved research funds of the central team will develop innovation programme SMEs (ZIM) now in detail. Impulses for sustainable growth: ZIM the ZIM is a program of the Ministry of Economics and technology, which is aimed at the middle class. It aims to promote the innovation of small and medium-sized enterprises. A part of the cost of research and development is financed within the framework of the project funding. Prerequisite for a promotion is, inter alia, that new products, processes or technical services be developed that significantly exceed the previous. Policy is the international State of the art. Info: to the J.v.G Thoma GmbH J.v.G. headquartered in Freystadt in der Oberpfalz serves customers throughout Europe, America and Asia. The services of J.v.G Thoma GmbH comprise the consultancy in the field of solar energy production, the realization of solar factories as well as the purchase and sale of solar components. Moreover, operates J.v.G. as a consultant for major customers in Europe and Japan. The company can look back on more than 20 years of experience.
