Introduction

This chapter covers the fundamentals required for the construction of a successful solar power system. At present, one of the problems associated with large-scale solar power construction is that most contractors, regardless of their long-term construction experience, do not have adequate engineering knowledge and the specific construction management skills, methodology, or logistics planning, nor are they familiar with dynamic test procedures discussed in earlier chapters. Construction recommendations presented in this chapter provide measures required for constructing and testing solar power systems in order to meet the design engineering and operational standards outlined in Chapter 4.

What Is Special about Large-Scale Solar Power Construction?

Large-scale solar power system integration, unlike conventional electrical system contract work, is multidisciplinary in nature and requires considerable experience in a multitude of disciplines. These include electrical engineering, solar power system design, civil/structural engineering, and specific knowledge of solar power system management as outlined in Chapter 4. Furthermore, large-scale solar power system installations require a cadre of technical personnel who have fundamental skills in solar power systems and have thorough knowledge and experience in electrical-electronic engineering. In particular, large-scale solar power systems, during the integration phase involve a series of continuous solar array system and subsystem dynamic tests that require proficiency in elaborate test and acceptance procedures.

Study and Evaluation of Engineering Plans and Documents

To be successful, technical and construction supervisory and construction management personnel must thoroughly evaluate the entire engineering design documentation and specifications. It should be noted that large-scale solar power systems are usually complicated and involve several thousand PV modules and solar power system equipment and support structures. In addition, large-scale solar power construction most often involves a considerable amount of solar platform preparation, PV support foundation work, logistics, and environmental engineering tasks. All of these are significant cost components. As such, oversights or negligence in cost accounting may result in serious consequences. Some of the significant tasks that are required for successful project construction include the following:

1. • Material takeoff

2. • Preparation of shop drawings

3. • Material and equipment procurement

4. • Workforce mobilization

5. • Construction crew training

6. • Preparation of construction project supervision and management procedures

7. • Site logistics, which includes material storage, site office space, site assembly location, material handling, material transportation, equipment rental, and environmental compliance procedures etc.
