SolarChill A - Installation in Gatab, Marsabit county, Kenya

Kenneth Njeru and David Ogutu

AIC (African Inland Church) Gatab Health Centre is situated at Mt. Kulal in Marsabit county, about 700km from Nairobi on the shortest route, i.e. Laisamis - Namarei route. The area between Illaut and the junction to Gatab is not very safe and robbery is likely to happen. It is therefore advisable to use Marsabit route through Civicon junction which is safer but very long. Climbing Mt. Kulal on the way to Gatab is one major challenge even to people living in this region. The road is rocky, rough and the highest speed one can drive is not more than 20km/h. The area is also characterized by Steep valleys and cliff which are very dangerous during rainy season. Due to this reason, there are no commuter vehicles to Gatab.

The health facility shares the same compound with a mission centre. This is where AIC missionaries are accommodated whenever they visit the area to support the health facility and Samburu community. The only Guest house available in Gatab was built by AIC missionaries and one has to make arrangement for accommodation and meals early in advance. There are no eating places/food kiosks in the area and most people survive on one meal a day.

AIC Gatab health centre was built by the missionaries and is now managed by the local AIC Church. The nearest health facility is Illaut dispensary which is about 137km away. Major services like x ray, dialysis, surgery etc can only be obtained in Marsabit, Isiolo or in Meru. See below some of the services offered at the facility.

The installation was done by Mr. Kenneth Njeru, technical service from CHAK, the driver was David Ogutu.

Partnering with Superfluid labs

We did a successful partnership with Superfluid Labs  ( ) for a market study in Kenya. The outcome was a survey of the most influencing parameters for the off-grid market and the market potential for off-grid solar direct drive refrigerators in Kenya.


The most important findings:

Interestingly, there are a lot of pay-as-you-go providers in Kenya, representing about 30% of the PAYG market. 

More than 77% of the Kenyan households are not yet connected to the grid, currently only 4,5% use off-grid solar.

Refrigerators rank on place three, directly after a TV on the most wanted products in a smart home system. These are about 20% of the customers of PAYG systems. 

Therefore, we are confident that the SolarChill B technology is ready to enter the wider commercial market

Sustainable Development Goal 7

A new study on Sustainable Development Goal 7, to ensure

access to affordable, reliable, sustainable and modern energy for all, published by IEA ( is publicly available.

Energy access policies are providing progress towards

electrification, nevertheless, in sub-Saharan Africa there are more than 600 million people without access to electricity. In this region, the electrification is slowly declining. The strongest progress is in the countries Kenya, Ethiopia, Tanzania and Nigeria.

As shown in the figure, the SolarChill partner countries, Colombia has the highest electrification rate. Kenya experienced a strong increase, but the decline is clearly visible. Swaziland is almost at the same electrification rate as Kenya, the increase is steadily continuing.

In the Sustainable Development Scenario universal access to electricity will be achieved in 2030. Until then and even beyond, the SDD units from the SolarChill project will provide as a reliable basis for the supply of vaccines in rural areas.

MUMs Vaccination tool - GIZ innovation fund winner 2018

Together with a great team from GIZ Eschborn the SolarChill project won the GIZ Innovation fund 2018. 

The innovation fund aims at developing a mobile application "Vaccination Check". This app will connect parents and the health facility and will serve as a calendar, a reminder and a on-demand vaccination availability tool for the vaccines needed to serve the children in the best way possible. No single date for vaccination will be forgotten and only vaccines which are needed will be supplied.

The SolarChill website,, is now available in French. The translation was made by Mr. Wangho René Job. He is a Trilingual Translator (French, English and German) and is located in Yaoundé, Cameroon.

Having the website now available in 3 different languages will increase its rating of viewing, reading, knowledge and wider acceptance of its works by the people. It is very important that more people around the world can learn about and gain access to SolarChill Technology and the SolarChill project, as they affect people around the world in general and in areas without a source of conventional electrical energy.

Conference international, Yaoundé, Cameroon

The international conference on SolarChill units was held the 05. June in Yaoundé, Cameroon. Partners were the Programme Organisation et Developpment des Communautes (PODC, Cameroon) et Solafrica ( The aim was the further dissemination of SolarChill units in Cameroon.

During the meeting it was agreed, that PODC and Solafrica will obtain 5 SolarChill A units from our partnering manufacturer Palfridge (eSwatini) as a donation as soon as the units are available.

A site visit at Naikarra Dispensary, Narok county was done together with Rebekka Oelze from the Christian Health Facility Kenya (CHAK) and Dr. Simon Mischel from the SolarChill project. After a warm welcome of the local health workers we visited the installation place for the SolarChill A vaccine refrigerator. At the moment the health facility uses an old-fashioned absorber refrigerating box driven by LPG for cooling the vaccines. As the nearest place for obtaining LPG is about 50 km away, it is a hard task to ensure the delivery of LPG. Another problem is the limited space such a box provides. See the picture section for more information on Naikarra dispensary. 


Naikarra is also an excellent place for installing a SolarChill B unit. The nearby church provides a place where the whole community gathers at the evenings or during community events. Therefore, a pre-site assessment was carried out during our visit to gather important information about the local conditions (e.g. roof structure, room availability). 


Installation of a B Medical TCW40SDD unit, La sierra Nevada de santa marta, colombia

Rafael Hernán Rivera Caballero performed an installation of a B Medical TCW40SDD unit in Pueblo Bello, Departamento del Cesar in the Sierra Nevada de Santa Marta. 

The installation site is about 6 hours away from Valledupar city. To reach the site, it takes about 2.5 hours by car followed by a 3 hours hike along the Guatapurí river. 

The solar panels were assembled at the site and then mounted on a structure specially designed for the housing of the panels. 

Everything went quite well during the successful installation of the unit in an off-grid area somewhere in the Sierra Nevada de Santa Marta.

Installation team: Carlos Ferney Lopez Prieto and the team from Caldono

The SolarChill project reached an important milestone.


The installation of the first B-Medical SolarChill unit took place in Caldono, Cauca province, Colombia in the health facility "punto de atención Caldono".

First, the solar arrays were installed at the roof of the health facility. Second, the unit was installed inside the building. After wiring and successful testing of the complete installation, the setup was finished. Running for approximately 24h, the temperature inside the vaccine compartment of the B-Medical unit reached about 5.5 °C. This temperature is well within the desirable range of vaccine storage. With the in-build monitoring device we are able to monitor the ambient and inside temperature and thus are able to monitor the performance of the unit.
