Photovoltaic systems with monoaxial sun tracker

The photovoltaic plant with automatic one-axis sun tracker allows to optimize the efficiency and to earn up to 35%, in comparison with the traditional fixed installation with azimuth and tilt constant.

The following pictures show the European energy production per year and per kWp installed. Moreover, they illustrate the increase in efficiency through the employment of a photovoltaic system with automatic sun tracker on one axis, N-S (azimuth) oriented and inclined at an angle of optimal tilt (fixed altitude).

The single string, on which photovoltaic panels are installed, consists in a metallic structure designed and realized by El.Ma.

It can follow the sun track on the azimuth axis thanks to a linear actuator equipped with a DC low voltage engine with encoder and with a rigid transmission system

The sun following control is represented by the solar tracker developed by El.Ma. that performs the real-time calculation of the sun coordinates in relation to hour, date, latitude and longitude, with the maximum theoretical accuracy.

Every sun tracker can manage two different strings with consequent advantages, mainly in terms of costs. The system movement (of those the frequency can be settled on the basis of the angle i.e. of the time) is performed with the speed and position control as, in comparison with the traditional tracker systems, the engine is supplied in PWM with acceleration and deceleration ramps.

The parameters related to the installation area are settled through the keypad and the display on board or through a serial connection RS232 with a PC; the hour and the date are acquired automatically by the receiver DCF77 with the maximum accuracy.

Moreover, the sun tracker is supplied with many temperature sensors (PT100) and an anemometric sensor for reporting serious atmospheric conditions; in addition, digital I/O have been considered in order to manage the safety procedure and any other alarms.

By connecting to this link it's possible to view in real-time the parameters of the monoaxial PV solar plant, installed by El.Ma. in order to test this kind of technology.
