    Investigation of the potential of using wind-photovoltaic hybrid systems for rural secondary schools: the case of mama Clementina foundation secondary School in Makambako
    (Unversity of Dar es Salaam, 2014) Mkini, Luka Charles
    This study aimed at investigating the potential of using wind and solar energy for generating electricity to meet school demand in rural secondary schools the case of Mama Clementina Secondary School Makambako. Most of the schools are far from electricity grid. In this work, wind and solar patterns suitable for generating electricity have been investigated. Also, the design analysis of wind – photovoltaic hybrid system for generating power to meet school demand has been made. Data used were collected through questionnaires, interviews, and measurement. Respondents were head of school, teachers, laboratory technician, and students. Survey was made to government institutions, agencies, NGOs and private organizations in order to obtain data on wind and solar energy resources, and materials used for solar and wind energy generation. The data analysis and modeling of the hybrid system was done by using the Hybrid Optimization Model for Electric Renewables (HOMER) computer software. Based on the data analysis the load demand for basic needs of electricity in the school with 420 students was found to be 27.229 kWh per day. The design analysis revealed that this demand can be met by solar PV generator of 5 kW, wind generator of 3 kW and 12 battery bank of 4200 AH. For further studies, it is recommended to collect enough wind and solar energy data to evaluate grid connected, diesel generators and stand alone wind–PV hybrid system options for different secondary schools in rural areas
