This research project focuses on the process, development and outcome of collecting and storing energy through photovoltaic panels connected to batteries. The main aims of the project are: to find out if the batteries can be used to store energy while simultaneously having a load connected to the photovoltaic panel; to carry out an experimental campaign for a realistic device; to learn how the charge controller works; to experiment first-hand with real material in a laboratory and outdoors; and to see if this system could be economically feasible especially as an alternative energy source for cooking in developing countries. This system would allow the user to consume electricity during the day, for example for cooking, while the batteries are being charged so that when there is no sunlight, like at night, electricity supply would still be available. The implementation of photovoltaic panels along with storage batteries could solve many electrical supply problems worldwide. For instance, in developing countries where there is less and less firewood and its use is unhealthy due to poor ventilation of houses, in places where electricity is unaffordable or non-existent and where poorer populations of the world cannot find other means of fuel for cooking or to provide for their minimal energy needs.
Throughout this project the main components of a photovoltaic system will be explained as well as some basic concepts related to solar energy. An in depth analysis of the experimental results obtained will also be made. In order to show the positive impact these kinds of systems could have in certain areas of the world, the energy access situation in developing countries is analysed and a specific case study is applied for Nigeria. In the conclusions of this project the objectives achieved are mentioned, such as being able to decipher the functioning of the charge controller of the device used or being able to carry out an experimental characterization campaign of a realistic device.Ingeniería de la Energí
