"In Spain, now the authorities have learned much from the construction mistakes of the past," reports Andreas Fleischmann. "With regard to the landscape, they have become very sensitive. The obstacles for the approval of building work are always high. We have an edge here because our tracking lies below 2 meters. Till the middle of the year, we alone installed at least 300 plants in Spain. "In the meantime, interest in the patent-pending tracking system 's:wheel' has spread to the neighboring countries in the Mediterranean region."
The multidimensionally moving triflex® R energy supply systems in the enclosed model "TRC 70" display their strengths in the photovoltaic plants. They were specially developed by the igus® GmbH, Cologne, for robotic applications and prove themselves here in all solar plants. The tribo-optimized polymer plain bearings from igus® are also used. "We are so confident of our system that we offer a guarantee of 25 years in combination with a maintenance contract. With it, we also provide the required safety for investment funds," clarifies Andreas Fleischmann.
Whereas the first small photovoltaic plant with a total of 200 kWp installed power went into operation in a Spanish vineyard, the main target clientele is the power plant construction sector. "We build plants of sizes 5 to 8 MW, which means that the plot sizes alone should amount to 80,000 and 150,000 m²," says Andreas Fleischmann. "At present we don't implement any special requirements yet, but still work in the common-part area. However we will further expand our product range to also utilize sunny hillsides, for instance!"
The company looks to the future with more than optimism. Started out with three people, today the location in Schwandorf and headquarters in Cham already employs over 300 people.
The one-axis tracking systems can pivot up to a maximum 270°. "Per day we have about 25 switchings. The energy chain moves at a very low speed. The solar lines which lead power from the solar modules are safely protected and guided in it. Depending on how the plant is connected, it is AC or solar or DC power lines," Gerhard Dirscherl explains the system.
"As a rule we supply the mechanics and the customer contributes to the electrical system," says Andreas Fleischmann. "But if necessary we also undertake the electrical component. In this case, the topic preassembled energy supply systems might become important. For us, that facilitates planning, construction, installation and starting up of the entire plant. But till now we have focused purely on the mechanical component due to capacity reasons. “
The goals of RWenergy stand defined. The entire Mediterranean region is to be tapped bit by bit. The market for renewable energy will continue to grow. "We offer a reliable and maintenance-friendly system. A part thereof are the energy supply systems which prove themselves outdoors. In our view, nothing stands in the way of its further application," Andreas Fleischmann takes stock.
