Solar Power Generation by tracking direct sun rays
Single Axis Tracker Controller

Volansys brings you a flawless solar tracker engineered to deliver high energy annual output & crucial cost savings for ground mounted solar plants.

Out of the two components of Sunlight, direct beam carries 90% of the useful solar energy. Fixed flat-panel set to collect a high proportion of available noon-time energy but the same setup becomes ineffective during early morning and late afternoon hours. Significant power available during this time when the misalignment with a fixed panel becomes excessive to collect a reasonable proportion of the available energy.

The primary benefit of a tracking system is to collect solar energy for the longest period of the day and with the most accurate alignment as the Sun’s position shifts with the seasons.

Single Axis Tracker

Single Axis Tracker [SAT] system increases annual output by approximately 30% compared to fixed tilt setup.

Volansys’ SAT Controller help in achieving this additional power generation by accurately tracking the Sun’s position. The system is highly configurable and calculates the desired panel position based on defined system parameters.

The SAT Controller system also supports effective back-tracking to reduce panel shadow and increase the overall power generation during early morning and late afternoon hours.

How can it bring value?
Programmable panel tracking resolution (+/- 10 to 50)
Calculates accurate position of the Sun for any day of the year through Latitude, Longitude, Time zone and current local time
Configurable back-tracking feature to avoid panel shadow during odd hours
Accurate control of actual panel angle through PID implementation
Embedded Real Time Clock with leap year support to maintain time data
Rugged Design to withstand the Industrial Electrical Faults (a product can withstand 10kV ESD, 4kV EFT and 5kV surge transients)
Auto/ Manual / Stow modes selectable remotely through SCADA system or locally via toggle switch
Display and Keypad interface for user configuration and status view
Industry standard Embedded MODBUS – RTU Communication profile for external interfaces
System log can be retrieved through USB interface
Stores system log for 30 days
External interfaces:
  • Tilt Sensor (Over RS485-MODBUS-RTU)
  • Wind Sensor (Both Digital or Analog)
  • Relays, VFD (Variable Frequency Drive)
  • Connectivity to Master Controller (SCADA system)
  • USB 2.0 for system log retrieval or firmware upgrade
How does SAT Controller works?

The SAT Controller is a PID (closed loop) system. The system takes feedback from the tilt sensor and calculates desired angle based on the Sun position. It operates motor in appropriate direction to actual panel angles inline to desired panel angle.

The system also continuously measures the wind and set the panel to stow position if it detects higher wind.

SAT Controller can govern the motion up to 12 solar tables, each table consisting 75 PV modules and each module is capable of generating 150 Watts of power. Thus, a single SAT Controller can control the motion of panels generating nearly 150 KW of Power.

The indigenously Back Tracking Algorithm eliminates the panel shadow effects during early morning and late afternoon hours. This feature not only increases the power generation during this time but also increases the efficiency of PV panel modules.
