Controller ensures precision tracking for maximum capture of solar energy

12 July 2010

Yokogawa has introduced the HXS10 actuator control system for heliostats (reflectors) and photovoltaic panels. The product helps to maximise power generating efficiency by controlling the angles of heliostats and solar panels so that they stay pointed at the sun as it moves across the sky.

Based on the facility location, date, and time, the HXS10 calculates the position of the sun through a high-resolution (64-bit) solar position algorithm, and operates motors or hydraulic actuators to adjust the angle of the heliostats and solar panels so they stay pointed toward the sun.
