This document presents recommended design practices for stand-alone photovoltaic (PV) systems. Sixteen specific examples of PV systems, designed for different applications, are presented. These include warning signals, lighting, refrigeration, communications, residential, water pumping, remote sensing, and cathodic protection. Each example presents a system sizing technique that can be completed using the worksheets provided. The calculations are simple and straight-forward. In addition to sizing calculations, each example includes information about available hardware, wire sizes, and a line-drawing to illustrate installation techniques. However, the focus of this document is the presentation of a consistent system sizing technique.
