摘要

This paper presents a comparative Life Cycle Costing analysis to assess the financial viability of photovoltaic system for distributed micro-generation for electrical household energy in Namawanga, Kenya. Three scenarios were tested using Life Cycle Costing: low population density (cluster of 10 households) with low load (<2.5 kWh/month), low population density with high load (2046 kWh/mo.), and high population density (clusters of 50, 250, and 500 households) with low load. The analysis revealed that in general, photovoltaic systems for micro-generation was financially advantageous for the community when the population was characterized by low population density, rural, and small electrical load. The Life Cycle Costing also revealed that two of the most sensitive factors in determining the lowest life cycle cost are the distance (km) necessary for grid extension, and the electrical demand (kWh).
