This Study Guide presents some of the basic cognitive material that individuals who install and maintain photovoltaic (PV) power systems should know and understand. This information is intended primarily as a Study Guide to help individuals better prepare for the NABCEP PV installer examination but does not provide all of the materials or information needed for completing the certification examination. Knowledge of the information presented, including pertinent sections of the National Electrical Code and appropriate experience and qualifications are generally required of those applying for and completing the NABCEP certification process. This Guide is based on a task analysis for the PV system installer, which includes the following eight major job/task areas: 1. Working Safely with Photovoltaic Systems 15% 2. Conducting a Site Assessment 5% 3. Selecting a System Design 5% 4. Adapting the Mechanical Design 15% 5. Adapting the Electrical Design 20% 6. Installing Subsystems and Components at the Site 20% 7. Performing a System Checkout and Inspection 10% 8. Maintaining and Troubleshooting a System 10% The percentage following each task area represents the approximate emphasis that each topic is given in this Guide, and is the associated percentage of each topic on the NABCEP PV installer certification exam. This Guide is organized in the following manner: • Reference Resources and Additional Reading • Study Guide • Study Questions • Answer Key The Guide is intended to provide an overview of each of the major content areas of the above task analysis. A set of practice questions that relate to each of the major content areas is then provided. The questions are organized according to each content area. The answers to the study questions, along with related explanations, are given at the end of this Guide. The study questions span fundamental trade knowledge, codes and standards, and accepted industry practice in the relevant design, installation, and maintenance of PV systems. Many questions are based on system installation scenarios, requiring the use of schematics, diagrams, and equipment specifications. Guidelines for determining solutions to the questions may be found in the text of this Guide, or from the references listed below. In addition to the specific content areas listed above, knowledge and skills in the following areas are also required: • Reading and interpreting plans and specifications • Reading and interpreting codes and standards • Using basic mathematics and some trigonometry (addition, subtraction, multiplication, division, calculations of area and volume, fractions, decimals, percentages, calculating the sides of triangles, square roots, powers of numbers, and solving simple algebraic equations for unknown variables)..
