Solar photovoltaic is strongly proven for cutting down greenhouse gases emissions and environmental destruction problems that the world is facing today due to the use of non-renewable energy sources. Tanzania considered in this study is also experiencing these challenges with imbalance and unreliable electrical power supply more precisely in health facilities. Therefore, this study aimed to investigate and evaluate ways solar photovoltaic (PV) can be used to improve reliability of existing power supply in health facilities in Tanzania. This research adopts an exploratory case study approach with a qualitative method for collecting and analysing the data. The case chosen was Kolandoto Hospital- Tanzania. The methods used for collecting data are measurement, participatory observation, participatory workshops, interview and documentation. The empirical findings have been analysed and used in calculations of the solar PV components that can be integrated in existing power system. The modelling of hybrid of solar PV and existing power system is carried out by use of HOMER software to get the optimal size of solar PV components. The results show that solar PV with backup system interconnected with power grid and diesel generator is feasible, and it provides solutions to energy security problems at Kolandoto hospital. Appropriately configuration is designed and proposed for selected emergency health appliances considered as critical loads in this report. The use of energy efficiency devices, replacement of old electrical equipments and exploitation of thermal solar for heating purposes are recommended to support the proposed solar PV system and to reduce further the electricity bills. In the future without budget and regulations constraints, net metering and expansion of the designed system to cover total load of the hospital will be more cost effective.
