A world first, Specialized Solar Systems completed the installation of a sub-centralized solar energy power station in conjunction with an innovative client in Cape Town, Zonke Energy.  The installation was done on the outskirts of Cape Town in a suburb called Jabula where grid power is not available. It consists of a sub-centralized solar energy unit which is a solar energy producing station that supply’s remotely managed DC solar energy from a central point that will branch out to supply much needed solar energy to a further 9-11 house-holds.

Specialized Solar Systems utility-based solar management integrated solution will supply all the necessary tools in an easy to use, tiered-user, on-line framework for sustainable and remotely managed energy supply for the project. The integrated solution is used extensively in many off-grid solar electrification projects where remote system management and ground management rely on the real-time data with automated client billing, switching and comprehensive system management.


6 Solar Sentry designed for Botswana Police Service

6 Solar Sentry designed for Botswana Police Service leave our factory for delivery in Botswana.

These Solar Sentry Trailer units are designed and manufactured in South Africa by Specialized Solar Systems for SSS-Grit-Tech in Boitswana.

The unit is a robust power-house on wheels used for combating crime and also road safety. The design of the Solar Sentry is especially suited to traffic check-points at night. The unit is a self-sufficient solar energy supply for 4 x 100 watt 24-volt DC floodlights that illuminate the road surface for law enforcement officers to have a safer working environment during field operations. The high powered lighting can be extended to a hight of 3 meters.

 With its unique design the Solar Sentry is easily deployed and can be towed behind fast moving vehicles at up to 80 kilometres per hour.

The 15 inch tires make the Solar Sentry capable of being towed in most terrains.  Within minutes, law enforcement officers can light up their environment and safely fulfil their duties. Additional AC power outlets also allow charging of AC electrical equipment.

During the daytime, the Solar Sentry, equipped with expandable solar panels, can supply up to 6kWh of power to the battery bank, which is safely hidden away within the Solar Sentry's strong body. With a battery back-up power bank of up to 24kWh the Solar Sentry can provide 14 hours of high-powered lighting during the night and has an additional 14 hours of autonomy without being charged by either solar or AC power (totalling to 28 hours of lighting).    

The Solar Sentry can be connected to a 220V AC outlet, allowing the batteries to be charged without extending the PV array. The Solar Sentry includes a blue tarpaulin (cover) with a 25mm high-density sponge to protect the solar panels.

These units each have the following specifications:

  • 4 X 100W Super Bright DC powered LED lights
  • 1 X 3M extension/retractible mask(boom)
  • 1 X Blue LED flashing light
  • 10 X 200A deep cycle batteries
  • 1 X 50 A MPPT
  • 1 X 3KVA Inverter
  • 4 X PV Panels (1.2 kW)

The Solar Sentry can also be customized in design to fulfil a specific requirements. Please contact This email address is being protected from spambots. You need JavaScript enabled to view it. for more information.


Your Piece of the Sun Energy, Gender and Poverty in Urban South Africa

Your Piece of the Sun Energy, Gender and Poverty in Urban South Africa

Specialized Solar Systems technologies feature in this short film and are used in the iShack project (10:40 - 14:10).

“Your Piece of the Sun”, a captivating film (25 minutes long) produced by Lloyd Ross and Joelle Chesselet for Sustainable Energy Africa, explores the challenges of energy, gender and poverty in urban South Africa. Through illuminating case studies and interviews with people on the ground, new approaches and innovative solutions to energy service delivery for low-income households are illustrated.

This film is intended to raise discussion and awareness and inspire innovative work in improving energy service delivery and access for low income households and in turn improve socio-economic development.

Geelhoutboom 101 kWp Grid-Tied Solar System

Geelhoutboom 101 kWp Grid-Tied solar system

Specialized Solar Systems installation team busy with the beginning stages of a large 101 kWp Grid-Tied solar system that will supplement the energy usage for the new upgraded blue berry pack house for the van Greunen Boerdery at their Highfields Blue Berry Pack House just a few kilometres outside George, The Garden Route South Africa

Images from the Geelhoutboom 101 kWp Grid-Tied solar system installation (click to enlarge)

The 100kVA Grid-tied will make use of:

  • 332 x 305watt solar PV modules (101260WP)
  • 4 x 27.0 ECO Fronius Grid-tied inverters

This is the first phase of the project and is expected to be completed by 2 December 2016. Thereafter and with careful monitoring, the system will be expanded for more solar yielding capacity.

The Grid-Tied solar system is designed, supplied and implemented by Specialized Solar Systems in collaboration with our solar partner, SSK (Sentraal Suid Ko-operasie).

This system connects the solar panel installation with the main electricity grid (ESKOM) and is known as a grid-tied solar power system. If legislation allows in the near future, excess energy could be fed back into the grid with a special meter.

18 kWp Loggernberg Grid-Tied Solar Installation

18 kWp Loggernberg Grid-Tied Solar Installation

Specialized Solar Systems recently completed 18 kWp grid-tied solar system installation for a client staying in Glentana in the Garden Route, South Africa.



The grid-tied solar installation used 72 x 250 PV solar panels , a 20 kW Fronius Symo inverter and took 2 weeks to complete.
