Slovakian startup Sun powered systems, s.r.o. has developed an automated photovoltaic system that can be used for various applications in arable land and crop cultivation. The photovoltaic device can provide off-grid power for the owner, assist in vegetable processing, prepare ready-to-use vegetable products or carry out product packaging.

Connected to a moveable device beneath the solar panels, the system is capable of linear motion combined with the synchronized circular motion of the robotic arm itself, operating in a helical 60- or 30-centimeter width. The rotating arm is driven by a motor powered by photovoltaic panels fixed to the arm, the system does not require connection to the grid or any other external power source.

The system uses an AC asynchronous motor with a speed of 1500 rpm and an operating power of 750 W. It can be equipped with commercial small solar modules, as well as LiFePo cells and frequency regulators.
There are several versions of this system. The minimum configuration version of the robotic arm is 6 meters long and has an output of 1kW. It is reported that it can cover an area of 104 square meters of arable land. The highest configuration version of the robot arm is 18 meters long and has an output power of 2.4 kW, which can cover an area of 994 square meters of arable land.
The system is capable of clearing weeds within a given line in one cycle, which is the number of revolutions the entire robotic arm must complete to turn around the axis of rotation from one end of the drive to the other. The system is easy to install, the farm operator can install the system using only soil screws, and it is very convenient to change the machine when needed.
This system is suitable for all individuals, small communities and businesses who want fresh and healthy vegetables.
