Agriculture Solar

Agriculture solar power has become a preferred method of energy supply and farmers are starting to invest in cost-saving and sustainable technology that is practical and environmentally friendly.  Solar power is used to generate electricity, pump and heat water to fulfil many useful functions throughout a farm.

The amount of energy from the sun that reaches the Earth each day is absolutely enormous. All the energy stored in the world’s reserves of oil, coal and natural gases is matched to the energy of just 20 days of sunshine. Because of this, it is easy to understand why solar energy farms are becoming more and more popular around Africa.


It is environmentally friendly ,reduction of water usage, low maintenance, simple and reliable. Protect your farm against foreseeable increases in utility prices with solar energy.


Advantages of solar power for farming is that it allows farmers to save on constantly rising energy costs of running a farm, farmers also stop relying so heavily on depleting resources like fossil fuels, which is costly and harmful to the environment.


Whether it is a fountain feature or a borehole, small or big, we have it all, solar water solutions for your every need.


Solar pumps are an energy efficient, environmentally friendly way to pump water for a variety of domestic and commercial purposes, including agricultural and residential irrigation and cattle or livestock watering

Specialized Solar Systems is a proud supplier of Lorentz pumps, solar pumps for drinking Water for people and livestock, Irrigation of crops, from smallholdings to large commercial farms and for swimming pool circulation/filtration which we call Responsible Leisure and much more…

VSD (Variable Speed Drives)

For high amounts of water, a large AC pump is usually required. These pumps require well regulated 3 phase AC voltage and current. By using an AC variable speed controller called a Variable Frequency Drive (VFD) or Adjustable Speed Drive(ASD) the pump motor will have the proper voltage and current. The trick is to supply DC from the PV array directly into the DC bus inside the VFD. The normal AC input is not used. As the sun rises and PV voltage and current increase, some VFD products will accept the input and when the power is high enough, it will start the pump. The PV array must be large enough to provide enough power to start the pump with including the head of water. The size of the PV array required for this method can be very expensive.

The first and most obvious way a VFD can save you money is through increasing the efficiency of your AC motors and decreasing electricity use. The amount of energy that a VFD can save depends on the average load of the motor and the number of hours per day it is turned on. While average energy savings varies, it’s safe to say that most AC motors do not need to be running at full capacity for most hours of their use. Furthermore, the initial cost of a motor or VFD is generally only a fraction of the cost of operating the motor over its life span. This means that a VFD system usually pays for itself in a matter of months or years.

Big or small

All farmers love their toys, from tractors to borehole pumps doing the job farmer style, let’s not forget the farmer’s wife, she might have a Koi pond or a water feature, small isn’t always a bad thing…
