Solar systems
Reliable and precise panel tracking

Many photovoltaic - or solar thermal energy systems - however, primarily solar power tower plants - track the sun with their panels. Along with a high level of efficiency of the panels, a continuously precise and reliable tracking are indispensable for a fast ROI and continuous, maintenance-free operation.

Based on its RV series, Nabtesco developed a series of gears specially adapted to the requirements of tracking systems - the STG series. These gears for the azimuth axis are suitable for collector surface areas of 20 to 120 m². Thanks to their non-self-locking power transmission, they easily absorb shock loads from wind gusts, etc. This spares the mechanical components. The trochoidal gears are maintenance-free until the typical oil change intervals.

• Reductions of up to 1:50,000 can be achieved
• Degree of efficiency > 80 %
• Lower energy requirement than conventional worm gear solutions
