Chapter 5: Solar Power Generation Project Implementation

Introduction

In previous chapters we covered the basic concepts of solar power system design, reviewed various system configurations, and outlined all major system equipment and materials required to implement a solar power design. In this chapter the reader will become acquainted with a number of solar power installations that have been implemented throughout the United States and abroad. The broad range of projects reviewed include very small stand-alone pumping stations, residential installations, solar farm installations, large pumping stations, and a few significant commercial and institutional projects. All these projects incorporate the essential design concepts reviewed in Chapter 2. Prior to reviewing the solar power projects, the design engineers must keep in mind that each solar power system design presents unique challenges, requiring special integration and implementation, that may not have been encountered before and may recur in future designs.

Designing a Typical Residential Solar Power System

A typical residential solar power system configuration consists of solar photovoltaic (PV) panels; a collector fuse box; a dc disconnect switch; some lightning protection devices; a charge controller for a battery if required; an appropriately sized inverter; the required number of PV system support structures; and miscellaneous components, such as electrical conduits or wires and grounding hardware. Additional expenses associated with the solar power system will include installation labor and associated electrical installation permits.

Prior to designing the solar power system, the designer must calculate the residential power consumption demand load. Electrical power-consuming items in a household must be calculated according to the NEC-recommended...
