Containerized off-grid solar solution for the Kunene Region
Ministry of Mines and Energy
2014
After successful completion of the Omusati off grid electrification project, CTS was successful in winning the bid for the second phase of containerized PV solutions for the Kunene region. With the experience gained from phase 1, the containers were optimized in many ways. The final design consisted custom build 20ft container by Namspace in Swakopmund.
Sites that were electrified in the Kunene region are:
- Otjitjekua School
- Otjiu School
- Otjiu Hostel
- Epupa School
The project included the following:
- Upgrading of all government building wiring as per national standard for 4 sites in the Kunene region:
- Manufacture, supply and install container power units for these sites.
The power containers consisted of ca 2.8kW of PV modules installed on the roof as well as 4,500 Ah of battery capacity. Five kVA inverter charger and two 70A BlueSolar Charge regulator all from Victron Energy complete the system. Remote monitoring of all sites is achieved by using the Victron Color Control GX unit.
Upgrade and Expansion of an Off-Grid PV System - Farm Ombirisu
Private
2018
An existing off-grid solar PV system was expanded to a total of 4,44kW on the farm Ombirisu north of Okahandja and the battery was upgraded to a Lithium-ion technology.
Final System Specifications:
- 6 x 295W Canadian Solar have been added to an existing PV array to deliver a final capacity of 4,44kW
- Replacing old charge regulators with 3 x Victron MPPT 150/70
- Replace old battery with 1 x BlueNova Lithium-ion battery 24V-24kWh
- Pole mounted solar array
- Online connection with remote access
Pioneerspark Medical Centre
Pioneerspark Medical Centre
2017
Pionieerspark Medical Centre can call themselves a proud owner of a 38kW photovoltaic grid feed system. Considerable savings on the monthly electricity bill are achieved as most of the electricity requirements are produced directly at the customer. Excess energy is fed back into the grid and credited on the monthly electricity bill by City of Windhoek.
The system consists of 144 265W PV modules mounted flat on the roof of the building with 2 Fronius three phase grid feed inverters and remote monitoring via the Fronius App on the cell phone. Remote monitoring allows CTS to advise the client on possible faults and recommended actions to be taken.
Installation of new Steam Boiler at Hartlief Windhoek
Hartlief
2012
A 1.5t boiler was installed at the Hartlief factory to cater for the growing needs of steam. The project included:
- Installation of new steam boiler next to the existing boiler
- Modifications to HFO line to cater for new boiler
- Commissioning
Over the past year's minor refurbishment, maintenance and upgrading projects where completed as well such as:
- Installation of condensate pumps to reduce back pressure of equipment inside the factory
- Raising current condensate storage tanks to increase head pressure for feed water pumps
- Three monthly service of both steam boiler and yearly inspection with Ministry of Labor inspectors
A La Mer Laundry - Swakopmund
for A La Mer Laundry
2017
When A La Mer Hotel in Swakopmund decided
to expand, they approached CTS with a unique challenge: to create a functional
laundry that was both energy and water efficient, and would also fit into a
small space, while being whisper quiet, so as not to disturb any guests. In
addition, the laundry has to perform excellently, producing quality wash,
tumbling and ironing results. Only one brand came to mind: Miele.
Miele recently launched new bench mark
machines, which have short program cycles, excellent spin performance, a
redesigned patented honeycomb drum and have low consumption values. A La Mer
Hotel was the first in Namibia to purchase these new machines.
CTS installed washer extractors with water recovery units, as well as automatic dosing systems, to ensure the best quality wash, every time. The tumble drier has an air recycling system, saving up to 60% of energy. And with a matching drying ironer, optimum finishing results are achieved. Small accessories made this laundry a complete turn key solution.
Farmers Meat Market Mariental goes green
Farmers Meat Market Mariental
2012
Central Technical Supplies (Pty) Ltd. – Geiger Engineering (CTS) was approached by Farmers Meat Market Mariental to design, supply and install a solar water heating system with the aim to reduce the monthly diesel consumption as two diesel boilers are operated to heat water up to 82 deg. C for production purposes.
The water requirements of the abattoir are as follows:
- 2,000 liter/hour @ 45 C°
- 3,000 liter/hour @ 60 C°
- 500 liter/hour @ 82 C°
This adds up to a total daily water requirement at 60 deg. C of roughly 25,000 liter.
The system is design such as to preheat water from 18 deg. C to between 50 deg. C and 60 deg. C before supplying the diesel boiler system, thus reducing runtime and diesel consumption of the diesel boilers. A 20,000L stainless steel tank (non pressure tank) manufactured locally according to CTS design, acts as the buffer tank for the daily water requirement. A total of 120 flat plate collectors supplied by Solsquare Namibia with a total surface area of 300 m2 are connected by means of a 450kW Alfa Laval flat plate heat exchanger to the water tank.
A set of two Calpeda circulation pumps connected to Danfoss variable speed drives and a timer circuit guarantees at all times that the heat from the collectors is effectively transported to the water tank. Flow as well as temperature monitoring on all four ports of the heat exchanger make it possible to determine the instantaneous as well as accumulated kWh produced from the collector field.
Furthermore additional heating energy is obtained from the ammonia refrigeration plant. A heat exchanger is installed on the ammonia discharge side before the existing cooling towers to be able to heat the water during night time as well, as this is the time when the refrigeration plant runs at full capacity to cool down the newly slaughtered meat in the cold rooms. Again flow control and temperature monitoring on the hot water side of the heat exchanger accurately indicate heating energy obtained from the refrigeration plant.
A total of four pump sets have been installed and pumps are cycled on a 24 hour basis in automatic mode. Should at any given time a pump fail, the system can be switched to manual mode to be able to repair the pump without system down time and a resulting increase in diesel consumption.
All systems components are sized such as to allow for future heating capacity upgrades should it be required.
After a year of operation, the plant is performing better than expected and the client is able to safe nearly N$ 60,000 per month on diesel costs, bringing the payback period of the entire system down to below two years. This clearly shows that solar energy, be it for heating or for electricity production, surely is the way forward for a cleaner and greener future for generations to come. CTS is proud to be part of making Namibia and the world a better place for our grandchildren to live in.
