CO2 savings

With the TSS infinitum control box and the TSS infinitum TCO software tool various diesel hybrid and solar only solutions can be provided. In below table we show the various cost and CO2 reductions you can achieve.

The TCO calculation TSS provide is taking into account the cost for maintenance and fuel. Transport of diesel and maintenance crew is not taking into account as this is depending on the location where the system will be installed. Each location requires a different solution resulting in a project specific TCO as shown right side.

TSS4U Successful track record in Africa

TSS Successful track record in Africa

TSS the world’s most trusted builder of fully integrated and optimized pure solar and solar hybrid energy solutions for remote telecom sites successfully established presence in Africa with a new office in Nairobi, Kenya.


TSS was founded in 2003 by former management of Shell Solar. The company is headquartered in Eindhoven, The Netherlands, and has additional offices in Abu Dhabi UAE for the Middle East Market and Kuala Lumpur, Malaysia for the Asia Pacific market. We equally work with numerous partners in Europe, Asia and Africa.

With over 25 years of in-depth experience in off-grid systems, and having successfully serviced the high standard oil and gas industry and deployed over 1,500 solar and hybrid systems across Africa, South East Asia, Middle East and Europe, it was time for TSS to have a footprint in Africa.

As a result, TSS expanded its sales organization and Kenya is one of the highly suitable locations to cater for our African target market where we are experiencing a rapidly growing interest in our solutions.


Kenya’s location allows easy access to the rest of Sub-Saharan Africa and facilitates TSS to respond faster to customer support requests, and more efficiently support our partners.

There are thousands of telecom sites without reliable grid connection which translates into huge energy costs for operators.


TowerXchange, the independent community for operators, towercos, investors and suppliers has also forecasted that the volume of new build sites will be the highest in Africa with Countries, MNOs and Towercos making significant investment in cell site energy, and rural electrification with sustainable, environmentally friendly solar solutions.

TSS solutions has developed and perfected to solve exactly the kind of infrastructure challenges that operators are facing in emerging markets like Africa and addressing key concerns like grid availability, reliability, future energy requirements and expansion and how to cost efficiently power both existing and new sites in rural areas.


Esther and the team in Kenya will be collaborating with local partners in the Sub-Saharan region who have teams in place for installation, operations and maintenance.

TSS- Art of No Cooling

“TSS - Art of No Cooling”

TSS’ expertise is in the development of equipment that can be placed in very hot climatic conditions. The presence of electronic equipment in such hot conditions generally leads to the problem of overheating which can result in inefficient functioning or even a complete failure of the system.


To tackle and alleviate the hitches and inefficiencies that arise as a result of heat, engineers generally employ different cooling systems for forcing a good thermal management. This is normally achieved by the use of fans which don’t have a long lifetime expectancy.

TSS Engineers’ Philosophy: Bottom Up Approach

Innovative design combined with the right selection of components make sure our electronic equipment is highly energy efficient and as a result have only little heat dissipation and don’t require forced cooling by fans.

Furthermore, our specially designed electronic components have in-built heat spreading capabilities which help to spread the heat from hotspots by natural convection within the enclosure.


These intrinsically cooled components ensure that the control equipment inside enclosures are heated up only in a controlled manner up to a maximum of 85°C! Thus, redundancy for temperature dependent failure in tropical environments are secured.


Such an efficiently designed control equipment can simply be used in the shade externally without any form of forced cooling (e.g. under solar modules). Even if the ambient temperature in the shade goes up to 55°C, the equipment continues to function perfectly without the need for any external cooling and without any de-rating.

TSS brings solar to the highest level

TSS brings solar to the highest level

In close cooporation with VDL Mast Solutions in the Netherlands, TSS4U designed and developed a unique monopole solar system for our Algeria based customer. A system born from the need to meet various constraints like the remote location, harsh geographical / meteorological conditions and the potential risk of theft. All these aspects were taken into account in the design of a reliable solar only system to keep the operation up and running 24/7 with a total of 57 monopoles installed.

Our customer has been involved right from the preliminary design up to site delivery making this project a tremendous success.

The solar monopole systems, a first of its kind, features custom made 100% solar power rating, foot print reduction, anti-theft solution, signaling and internal cable routing.

57 x customized 15m high mono poles with 2 (3 m2 ) / 16 (26 m2 ) and 24 (40 m2) solar modules in Hassi Messaoud, Algeria for a Remote Telecommunication Unit (RTU) and Chemical Injection Package (CIP)

• Customized 15m high pole design in accordance with EN 1993-3-1
• Hot dipped Galvanized steel according ISO 1461
• Withstand 120 km/h wind velocity/load acc. EN 1991-1-4
• Remote controlled anti-theft-intrusion detection system at 5m & 8m from the pole
• Anti-theft concertina blade wire with cut detection
• Remote and local operation of the intrusion system
• Features internal cable routing
• Underground battery pit with opening detection
• Designed, engineered and produced in The Netherlands

McKinsey report – The case for committing to greener telecom networks

“Operators’ energy costs keep rising, but efficiency measures and organizational change can lower them by 15 to 20 percent in a year, benefiting company profits and the environment”

“In current mobile networks, for example, transferring data only consumes around 15 percent of energy. Some 85 percent is wasted because of heat loss in power amplifiers, equipment kept idling when there is no data transmission, and inefficiency in systems such as rectifiers, cooling systems, and battery units.

Green-energy suppliers are cheaper in some markets. In India, the cost per kilowatt-hour of solar power is about 35 percent lower than grid power and about 65 percent lower than generator-set power. Some telecom operators are already taking advantage of such price differentials.”

The case for committing to greener telecom networks

“There are opportunities for companies to cut costs by generating their own green power on site. Japan’s NTT DOCOMO is reported to have reduced grid-power usage by as much as 40 percent at some of its base stations by using solar panels and higher-capacity batteries”.

TSS4U Participation to TX – MENA 2020

TSS brand name is a standard of the most trusted off-grid solar solution at TX - Mena

TSS4U made a big impression during the Middle East North Africa TowerXchange “once a year event” in Dubai over the two days, thanks to its quality reputation with +1.000 running Solar sites over the last +15 years across the entire MENA region in the Oil & Gas industry.

All independent wireless tower company’s (Tower Co’s) and Mobile Network Operators (MNO’s) showed a particular interest in the off-grid TSS4U Solar only or Solar hybrid solutions in the Telecom remote areas.

It became very clear that the following USP’s were catching the attention of all:

  • A dual system set-up, based on two sub-systems, means there’s never downtime/only uptime
  • Passive cooled solar power system/control box, means no energy loss, reliability (no fans required, and no moving parts) & a continuous running system
  • System sizing on DC equipment (no losses from converting 48 Vdc to 230 Vac), means saving 20% – 30% on the solar capacity, space, capex

CEO, Dop Brzesowsky, who participated at the event was often asked what is the secret behind the TSS reliability and quality reputation explained the following:

“Based on more than 20 years’ experience in the off grid solar hybrid world, we have developed our own control systems and co-developed solar batteries for harsh environments (above +50 °C) and we learned the hard way how to build reliable Solar Hybrid Systems for rural- and very remote locations, which run 24/7, 365 days a year, easily 7 years continuously without changing your battery pack”.
