A methodology for photovoltaic system reliability and economic analysis
It is pointed out that the operation of large terrestrial photovoltaic (PV) power systems (over 50 peak kilowatts) is a fairly recent event. The present investigation provides a review of the characteristics of current and future PV systems and selects a methodology to allow the system designer to consider system reliability and maintenance parameters early in the design. The goal is to minimize the cost of system output energy over system life. Thus, cost per kW-hour is the objective function which PV system designers should minimize. Attention is given to an integrated reliability, availability, maintainability (RAM) model, which represents failure and repair, and provides the corrective maintenance portion of the yearly maintenance cost. The RAM model and a life-cycle energy cost model are combined to provide the information the designer needs for system optimization.
