Solar Cube Overview
The IMO Solar Cube has been developed as a ground breaking, easy to set up solar tracking and measurement controller with the exibility to
adapt to any installation.
The Solar Cube is an o the shelf controller designed for use on either one or two axis solar panel installations to track the sun’s movement and
provide optimum panel (or array) positioning. The sun’s position is calculated using the local time and date comparing this with the longitude
and latitude location of the solar array. From this data the Solar Cube calculates the ‘zenith angle’ and the ‘azimuth angle’, which together
exactly specify the position of the sun in the sky to within 0.01°.
To position the array the Solar Cube uses feedback from an electronic compass device connected via RS232 or RS485 which then activates the
solar array’s actuators until the correct position is reached. The compass is mounted directly on the array frame to give accurate positioning
information.
With the option of GPS positioning or manual inputting of the array’s location, the Solar Cube is easy to setup anywhere in the world. The Solar
Cube is a competitive solution for controlling each array or it can be congured to control up to 4 arrays from one controller providing additional
savings. Options for feedback and control from a single control station or via a web server are also available.
Solar Cube also oers data logging facilities using its own internal Micro SD card. Power output can be logged continually to produce daily,
monthly and yearly gures. Revenues can be calculated along with CO

reduction gures.

The sun’s position calculation depends upon the current time and date as well as longi-
tude and latitude location of the solar array. The results of this calculation are the ‘zenith
angle’ and the ‘azimuth angle’, which together exactly specify the position of the sun in
the sky.
