Interview with Rone Yousif from University of Applied Sciences Bonn-Rhein-Sieg. He is supervising the measurement concept at the three pilot sites of the EnerSHelF project in Ghana.
You recently joined the EnerSHelF project under work package 3.0. Can you tell a bit about your professional background and your experience in working with renewable energy?
I am very pleased that the University of Applied Sciences Bonn-Rhein-Sieg (H-BRS) gave me the opportunity to actively contribute to the project. In 2013 I decided to study mechanical engineering as I am very technically oriented. As part of my master’s degree, I focused on solar power and I have dealt with issues of energy meteorology. My master’s thesis investigated the influence of aerosols and clouds on photovoltaics (PV). It was fascinating to see how dust outbreaks in Ghana affect the PV performance but also to face the challenges that occur in the energy sector.
Interview with Mohammed Abass from WestfalenWIND. He talks about his role in the EnerSHelF project and the challenges they faced when setting up a Photovoltaic-hybrid system at the pilot site at Kologo.
You recently joined the EnerSHelF project through its industry partner WestfalenWIND. Can you tell a bit about your professional background and role within the project?
I completed my B.Sc. in Physics at Kwame Nkrumah University of Science and Technology (KNUST), Ghana, in 2012. In 2014, I came to Germany to do my master’s degree at University of Duisburg-Essen and now hold a M.Sc. in Mechanical Engineering. My studies were based within the internationally oriented study program International Studies in Engineering (ISE) and I specialized in energy and environmental engineering.
My role within the EnerSHelF project is to assist in setting up a photovoltaic (PV)-hybrid system at the pilot site in Kologo, Ghana. Additionally, I help to promote user acceptance of PV systems as well as its optimal usage. That also entails to enhance the understanding of sustainable electricity generation across the community. I think that if you want to bring new things to places or people, it is important to create the right access. Encouragingly, I noticed that the acceptance for PV systems in Kologo is already very high. Another part of my role within the project is the documentation of the process of setting up the PV-hybrid system in Kologo.

Interview with Dr. Emmanuel Ramde from Kwame Nkrumah University of Science and Technology (KNUST), Kumasi, Ghana. He explains the many areas he is involved in for the EnerSHelF project
As an associated partner to the EnerSHelF project, the Brew-Hammond Energy Centre (TBHEC) at KNUST is involved in WP3.1, which aims to provide a power demand model for Ghanaian hospitals. What is your specific role within this work package?
My specific role within this work package is manifold and diverse. First of all, I use my knowledge and understanding of the energy landscape in Ghana to get the right input parameters for the expected outputs of the developed model. Furthermore, I liaise with the utilities to get data for some selected hospitals. That also included locating a health facility in Kumasi which is now a part of the EnerSHelF project as a pilot site. During this process, I initiated a collaboration agreement with the management of the facility and coordinated the recent installation of the weather station and of the load measurement devices.
Interview with Ana Maria Perez Arredondo from Bonn-Rhein-Sieg University of Applied Sciences. She explains how and why she examines institutional structures in Ghana and points out linkages of EnerSHelF to her doctoral thesis on One Health.
You recently joined work package 1 of the EnerSHelF project which is examining the political economy structure of Ghana. Can you explain your role within this work package?
Sure. I will be looking at how the dissemination of technology, particularly photovoltaic (PV), is happening in Ghana. In particular, I will interview managers of health facilities to evaluate the challenges they have in relation to energy supply and their impressions towards renewable and non-centralized energy sources. The goal is to evaluate the market potential for PV.
Interview with Sarah Rabe from Bonn-Rhein-Sieg University of Applied Sciences. She talks about her role in the project as a linkage between the different disciplines, ensuring an active exchange among the work packages throughout the research process.
Interdisciplinarity is at the core of the EnerSHelF project as different academic disciplines and industrial partners are involved. What is the purpose of this holistic approach?
The holistic approach arises almost automatically out of the project’s topic. The technological transition towards renewable energy – in this case solar energy through photovoltaics (PV) – can only work if the product is of high quality and adapted to the specific region. But even well-engineered technology is pointless if it is not usable for or accepted by the people who are supposed to adapt it. Therefore, one needs different disciplines like engineering, meteorology, and socio-economy to tackle a holistic problem like the energy self-sufficiency of health facilities.
Interview with Samer Chaaraoui from Bonn-Rhein-Sieg University of Applied Sciences, Sankt Augustin, on the process of modeling photovoltaic systems. In cooperation with other members of the EnerSHelF project, he works on the mathematical representation of different effects and events that influence the operation of the system
When I searched for academic articles on solar
photovoltaic modeling and simulation, I have seen a lot of equations and
mathematical formulas. Can you explain in a more accessible way what modeling
of photovoltaic systems encompasses?
By modeling photovoltaic (PV) systems, we try to
find a mathematical representation of effects and events happening inside a PV
system. With this representation, we can simulate processes, such as the
conversion of solar radiation to electrical power, in order to estimate solar
yields – for instance for economic and ecological business case analyses.
Since the full representation of the real world is
not viable, we try to find mathematical representations which are simple enough
to be calculated quickly and are complex enough to give an acceptable result.
Therefore, it is especially important to validate modeling results with real
world measurements, to estimate the performance of the model.
You will find many approaches and equations, trying
to represent PV systems, which range from simple physical equations to more
complex methods. Each of these approaches result from different demands towards
the use case, usability, and accuracy of the model.
Interview with Dr. Kennedy Alatinga of the University for Development Studies on his involvement in the project as an associated partner. He explains his role in the quantitative and qualitative data collection in Ghana
You are an associated partner to the EnerSHelF project and involved in three work packages. Can you tell us about your role within these distinct packages?
I am the Country Project
Manager of EnerSHelF in charge of the socio-economic component of the project
in Ghana. In my position, I am involved in
developing survey instruments for data collection and analysis. Another
major task is to ensure that the project team gets ethical clearance from the
Ghana Health Service Ethical Review Committee for the project – which I already
How do you implement your tasks and areas of
leading the development of both qualitative and quantitative data collection
instruments. With these we plan to assess the impact of the institutional
framework – both in terms of prevailing technologies as well as socio-economic
conditions – on the decision-making behaviour of market actors regarding PV
Interview with Samantha Antonini from Bonn-Rhein-Sieg University of Applied Sciences on her tasks within the EnerSHelF project. She unravels her role as a linkage between project partners, researchers, and donors and the affiliated administrative challenges.
Besides the academic research and technological challenges surrounding EnerSHelF, its administration is central for the smooth progression of the project. Can you explain your role within the project in this regard?
I am responsible for facilitating collaboration across multidisciplinary work packages and reporting the project status to our project leaders and donors. In doing so, my work entails a diverse field of activities: I monitor the progress of research activities, generate the necessary documentation, organize regular team meetings, and assist staff and scientists with creating protocols, reports and many more. I also provide support for operational, procurement and legal aspects.
Interview with Seyni Salack and Samuel Guug from WASCAL (West African Science Service Centre on Climate Change and Adapted Land Use) on how they collect meteorological data for the EnerSHelF project at the field sites in Ghana.
WASCAL is involved in WP 3.2, which aims to forecast the key meteorological variables for solar power generation and consumption at the field sites. How does WASCAL collaborate with the University of Augsburg within the work package?
In collaboration with the University of Augsburg (UniA), WASCAL provides technical support in collecting, processing, and analyzing observational data from the local observatory networks and pilot sites. It also acts as an interface between the EnerSHelF project teams in Germany and local stakeholders, for instance the Ghana Meteorological Agency. With this, we aim to foster synergies among the actors to achieve a seamless workflow.
