17kW Grid Tied Photovoltaic System

Stier Vente Chartered Accountant

2017

In early 2017 Stier Vente Chartered Accountant did take the decision to move to renewable energy. A 17kW grid feed system was installed on the roof of the office building to reduce the monthly electricity bill.

A total of 67 260W PV modules and a SMA SunnyTripower 17kW inverter was installed. Remote monitoring allows CTS to advise the client on possible faults and recommended actions to be taken.

Containerized off-grid solar solution for the Omusati Region

Ministry of Mines and Energy

2013

CTS was awarded the first ever containerized off-grid solar electrification tender for the Ministry of Mines and Energy beginning of 2013. This project entailed:

Upgrading of all government building wiring as per national standard for 9 sites in the Omusati 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 3,000 to 4,500 Ah of battery capacity depending on site requirements. Five KVA inverter charger and two 70A Blue Solar Charge regulator all from Victron Energy complete the system.

With a total of nine containers, school, hostels and other government buildings were electrified. Each container was subdivided into two rooms for batteries and inverter technology respectively.

With our 36T/m crane truck CTS was able to transport the container to site, navigating through thick sand with ease.

Refurbishment of Outapi State Hospital Laundry

Ministry Of Health And Social Services

2014

CTS removed old and obsolete laundry equipment and installed new machines.

The installed equipment sonsisted of:

3 x new Primus RS35 washer extractors
3 x Maytag energy saving tumble dryers
2 x Miele through-feed drying ironers
including laundry trolleys, ironing trolleys, hand-irons and ironing tables

Supply and Installation of Automatic Weather Stations at Kanovlei and Koichab Pan

National Botanical Research Institute

2014

National Botanical Research institute approached CTS to upgrade two of their existing AWS to satellite communication and subsequent installation at Kanovlei in the Tsumkwe Area as well as Koichab Pan close to Lüderitz.

Communication is via Meteosat satellites and based on a “fire and forget” principal which unfortunately does not allow remote maintenance procedures.

The stations form part of the SASSCAL Weathernet and measure all important meteorological parameters.

Oranjemund Airport - Supply, Install and Commission of an Aviation Weather Monitoring System

DeBeers Marine Namibia

2015

DeBeers Namibia published a tender for the supply and installation of a weather monitoring system at the Oranjemund Airport. CTS was awarded the tender based on price, knowledge of the meteorological measuring equipment as well as quality of products. At time of installation the station was the most advanced aviation weather station in Namibia.

Technical Details of the system installed:

Ceilometer at end of runway 20 to measure cloud height at three levels up to 7,500m
Runway Visibility and Present Weather sensor at stop end of runway 20.
Present weather sensor monitors 7 different types of precipitation
visibility sensor takes background luminescence into account
Wind speed and direction a touchdown runway 20.
Wind speed and direction, rain as well as barometric pressure at stop end runway 20
AviMet server for processing of all data
3 workstations spread along the buildings for weather monitoring and supervision purposes
ATIS voice system transmitting on aviation frequency as well as telephone dial in the current weather conditions

All communication between the equipment and the AviMet server is based on wireless transmission to reduce cabling costs.

The weather information can be picked up rough 100 NM away from the airport by all approaching aircraft.
