Self-sufficient electrical total supply of the child village TUWAPENDE WATOTO in Dar-Es-Salaam Tanzania since August 2011 operational.

The SOLARtec began 2009 on behalf of the Luxembourg Ministry to supply selfly-sufficient with electric current a new child village (tuwapende-watoto.org) with 17 buildings. The complex consists of community areas, sleep-, teachers-, mother-houses, kitchens, laundry, shower rooms, a kindergarten and a primary school. There is no electrical supply over the public supplier and a change is neither on a short nor on a long-term basis available.

 

 

The IPS® technique container is the ideal solution, in order to generate with the help of solar energy a permanent, independent and economical energy and to stay independent until far into the future from the public supply network.


The IPS® stores solar energy in battery plants, converts this into alternating current, regulates, steers and distributes automatically the current to individual electric circuits.


The singular linkage of the inserted components under consideration of the specific characteristics and the control by the IPS® controller guarantees the all-season power supply round-the-clock.


72 high-quality solar and movable floor rack modules, specially designed by SOLARtec, on the roof of the primary school produce the direct current from the sun and store it into the battery plant of the IPS® technical centre. The dust proof and multi-level venting system flows around the inserted components with air-conditioned interior air, whereby optimal operating conditions are reached. Thus the working life of the battery plants of up to 10 years becomes possible.

The IPS® stores solar energy in battery plants, converts this into alternating current, regulates, steers and distributes automatically with a high-efficient energy management the electric current to individual electric circuits. The IPS® concept uses during bad weather phases a „back-up system”. This can be an existing external Diesel generator or an optionally available internal load generator.


This saves to a large extend fuel and costs and reduces the CO2-emmission. The entire plant data can be supervised from the distance over a standardised modem (GPRS) and if necessary a service can take place. Substantial characteristic of the IPS® technology is their reliable functioning by the redundant execution of special components and the easy handling. After a short briefing the users of an IPS® solution are able to operate their power supply independently. In Tuwapende the solar plant supplies the electrical current for the lighting, the refrigerators, the fans, TV and radio as well as the pumps for the water distribution in all buildings. Apart from the complete self-sufficient electrical supply the child village received an additional installation of tube collectors on 5 roofs for the warm water distribution.

IPS® technical centre is a 10ft and 20ft-DIN container developed and certified by SOLARtec and completely manufactured in Luxembourg according to the principle of the regional creation of value. The centre contains all necessary state of the art components, as well as a modern energy management (IPS®-Controller), the load dividers (8 lines), inverters, accumulator batteries and the Back-Up generator. Transport takes place by sea and overland route to the places of work (CSC-Certificate). So the assembling time is locally reduced to a minimum.
