SLEWING RINGS FOR LARGE SIZE SOLAR PANELS. A CASE STUDY

This paper presents a computer optimization algorithm for internal geometry of slewing rings manufactured at SIRCA S.A,. already used in large size solar tracker power plant. The model takes into account the sun position on the sky and the wind speed effect. The internal geometry of the slewing ring considers the geographic position of the solar panel by using the specific country solar and wind maps, respectively. The proposed slewing rings for single and double axes solar trackers ensures the optimization of converting the solar energy in electricity by a correct orientation of the PV panel.
