摘要：A photovoltaic (PV) generator was integrated onto the north facing roof of an energy efficient house in South Africa. The building integrated photovoltaic generator (BIPV) supplies power to the household loads and the grid and is also the roof façade. This paper presents an economic evaluation of the viability of the BIPV system using methods of investment analysis. The capital cost and life cycle cost of energy were found to be ZAR 52 631-58/kWp and ZAR 1-94/kWh respectively. The payback period was 8 years and adjusted internal rate of return 9.3%. Parametric sensitivity analysis revealed that a 50% decrease in module price results in a 29% reduction in life cycle cost of energy and more than 50% reduction in payback period.
