Stand-alone flat-plate photovoltaic power systems: system sizing and life-cycle costing methodology for federal agencies

Technical Report ·
DOI:https://doi.org/10.2172/6508951· OSTI ID:6508951

A simple methodology to estimate photovoltaic system size and life-cycle costs in stand-along applications is presented in this document. It is designed to assist engineers at government agencies in determining the feasibility of using small stand-alone photovoltaic systems to supply ac or dc power to the load. Photovoltaic system design considerations are presented as well as the equations for sizing the flat-plate array and the battery storage to meet the required load. Cost effectiveness of a candidate photovoltaic system is based on comparison with the life-cycle cost of alternative systems. Examples of alternative systems addressed herein are batteries, diesel generators, the utility grid, and other renewable energy systems. A companion document, Flat-Plate Photovoltaic Power Systems Handbook for Federal Agencies (Reference 10), is recommended for discussion of issues for evaluating the viability of potential photovoltaic applications; descriptions of present photovoltaic system applications; synthesis of lessons learned from photovoltaic system design, installation, and operation; and identification of procurement strategies for federal agencies.
