Upgrade and Expansion of an Off-Grid PV System - Farm Ombirisu

Private

2017

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

Supply and Installation of 3 Automatic Weather Stations in the Kunene Region

University of Hamburg

2016

The University of Hamburg approached CTS directly with the request to quote and subsequently manufacture and install 3 automatic weather stations at:

Khorixas
Kaoko Otavi
Okangwati

Once again, satellite communication has been chosen, this time not because of GSM not being available, but to reduce future cost of the stations as satellite communication for these stations has got no costs associated.

In addition to the basic data measured:

Wind speed
Wind direction
Humidity
Air Temperature
Irradiance
Barometric pressure
Ground Temperature
Rain
Leaf wetness

The stations are equipped with a WLAN interface. This allows the connection of 49″ SmartTV to be connected to each station to display the current weather inside close by offices.

Supply of Solar Resource Measurement Station to NUST

Namibia University of Science and Technology

2015

Central Technical Supplies was approached by the University of Stellenbosch to take part in a tender to supply a solar resource measurement station to the Namibia University of Science and Technology in Windhoek.

We were successful in winning the tender. The station is based on the Kipp and Zonen Solys 2 sun tracker with CMP 10 Pyranometer and CHP1 Pyrheliometer.

The station is based on the CR1000 logger from Campbell Scientific and measures wind speed and direction as well as ambient temperature, humidity and rain in addition to the solar resource data.

Installation of 4 Containerized off-grid PV systems in the Otjozondjupa Region

Ministry of Mines and Energy

2018

Central Technical Supplies was once again awarded the tender to electrify 4 remote localities in the Otjozondjupa Region of Namibia. Custom build containers where installed on site with SMA Sunny Island 8.0 inverter installed. In addition the offered lead acid battery technology has been replaced by state of the art lithium batteries reducing system maintenance. The use of AC coupled technology did allow for the SunnyBoy solar inverter to be in installed inside relevant buildings on which PV modules are mounted. All components are interlinked by means of wireless technology to allow for remote monitoring where GSM signal is of sufficient strength. System sizes vary form 3kW, 12kW, 15kW to 20kW of PV power while inverters are as much as 3 in a single phase cluster.

Sites that were electrified are:

Nhoma
Aasvoel Nes
Kanovlei
Grashoek
