Abstract:

This paper presents a solution for producing green energy using high concentration photovoltaics (HCPV) panels on large and medium sized ships. In order to have high efficiency HCPV modules are automatically oriented in the direction of the sun with dual axis trackers system. The solar tracker system for HCPV is designed to satisfy the conditions of the ship: oscillations and continuous displacement. This system can be used for the orientation a module or set of modules HCPV and is thus designed to be more efficiently. The control is provided by a PLC with a GPS module, analog input module for sensor connections and digital input/output modules for motors control. In order to realize orientation is calculated with precision the position of the sun using astronomical equations and information received from the GPS. Actual position of the panel is given by two sensors: a compass sensor gives angle toward the South Pole and a tilt sensor type ISU. The system is protected In case of damage and can be stopped temporarily if there is no sun or is strong wind, in which case it is taken out of the wind. Through this solution the solar tracker system for HCPV modules, it provides 25% -50% more energy than conventional panels.
