Sustainable Technology Transfer – Solar Power for Tanzania

This September 2012 volunteers deployed state of the art solar power installations to a school in Bagamoyo and a hospital in Lutindi. Wagner & Co and numerous other supporters made this transfer of sustainable technology to Tanzania possible.

A whiff of luxury – thanks to solar electricity!
Stable and reliably power supply – a given for us here in Europe – is a luxury in Tanzania, especially in rural regions. Regular power outages keep complicating the already difficult daily life.

Thanks to many years of good contacts to Germany the Mwasama Pre- and Primary-School in Bagamoyo as well as the Lutindi Mental Hospital in Lutindi now received solar power systems that assure a stable and independent delivery of electrical energy.

We already reported comprehensively about the background of the projects: Stable power supply for school and clinic in Tanzania

Together the world can be shifted a bit towards sustainability
Planning, coordination and acquisition of components were carried out by Peter Hoenen, engineer and product manager for off grid solar installations at Wagner & Co Solar Technology, who have many years of experience with similar off-grid projects. Hoenen also was on location and volunteered his time and experience to assist with the installation.

Werner Blauth, a member of the „Freundeskreis Bagamoyo“ (ring of friends of Bagamoyo) and director of the Lutindi Mental Hospital, together with his son assured that the container with the precious solar freight was released in time from customs at Dar Es Salaam harbor. Afterwards the many individual components had to be transported inland 75 km to Bagamoyo and 300 km to Lutindi. Thanks to Mr. Blauth’s commitment all parts arrived in time at their respective locations where they were eagerly awaited.

It took two days to install the solar power system in Bagamoyo. All in all 18 quality PV panels from REC were installed as part of a 4.2 kWp off grid system designed as a single phase AC coupled off-grid system with SMA inverters.

Installing the larger system in Lutindi with its 90 REC PV panels took four days. It was carried out as an off grid system featuring a 3 phase SAM inverter with a maximum output of 21 kWp.

The Solar panel manufacturer REC sponsored all 108 solar panels of both solar installations as well as the main components for the off grid system in Lutindi.

The Bethel Mission from Bielefeld, Germany (a not for profit foundation now named „Von Bodelschwinghsche Stiftungen Bethel“), that founded the Lutindi-Mental-Hospital more than 100 years ago, also supported the installation in Lutindi financially.

The Reiner Lemoine Foundation from the city of Neuss (Germany), which supports, among other things, development projects focusing on renewable energy, partly financed the project in Bagamoyo.

The company STAPEL GmbH from Ahlen, a Wagner & Co Solar Technology partner of many years, took care of installing the systems with a team of 4 volunteer technicians. Stapel entered the national German competition „Sterne des Handwerks“ (Stars of the Crafts) with this project.

Peter Hoenen arranged the contact to Wagner & Co’s Tanzanian partner ENSOL from Dar es Salaam, who was won over for the long term maintenance and technical support of the solar plants in Bagamoyo and Lutindi, thus ensuring durability and trouble free long term operation for many years.

Both projects are exemplary examples for sustainable technology transfer and worthy of imitation.
