Exam Details

The Nevada C-2G Photovoltaics Contractor examination contains 75 questions. Candidates have 150 minutes to complete the examination and must answer 56 questions correctly to pass.

The examination content is divided into the following areas:

• Photovoltaic Theory: 5 questions
• Electrical Interconnection: 15 questions
• Permitting, Inspection, and Utility Interconnections: 5 questions
• Photovoltaic Components: 15 questions
• Photovoltaic Installation: 10 questions
• Estimating, Calculations, and Design: 20 questions

Estimating, Calculations, and Design is the largest section of the examination. Candidates should be prepared to work with electrical values, system sizing concepts, conductor considerations, voltage and current relationships, photovoltaic array design, equipment selection, and other calculations associated with photovoltaic installations.

Electrical Interconnection requires familiarity with the way photovoltaic equipment interfaces with electrical systems. Study should include conductors, overcurrent protection, grounding and bonding, disconnecting means, equipment connections, and applicable National Electrical Code requirements.

Photovoltaic Components includes the equipment that makes up a photovoltaic installation. Candidates should understand the roles of photovoltaic modules, arrays, batteries, inverters, conductors, disconnects, overcurrent devices, mounting components, and associated system equipment.

Photovoltaic Installation covers practical installation principles, equipment placement, wiring methods, mounting, system configuration, and installation practices that affect safety and performance.

Open Book Test

The Nevada C-2G Photovoltaics examination is an open-book test. The approved exam-room reference is the NFPA 70 - National Electrical Code, 2017 edition or the corresponding 2017 National Electrical Code Handbook.

Candidates are responsible for bringing their approved reference to the examination. The reference may be highlighted, underlined, and indexed before the exam. Permanent tabs may be used to organize the book. Temporary tabs such as removable Post-it notes are not permitted.

The approved reference cannot contain written notes or additional loose or attached papers. Candidates should organize their NEC before test day and become comfortable locating important requirements without depending on excessive searching.

Open book does not mean the examination can be completed successfully by looking up every question from scratch. With 75 questions in 150 minutes, candidates have an average of about two minutes per question. Familiarity with the code structure, index, tables, definitions, and photovoltaic-related provisions can make a major difference in time management.

The other three references in this package are for preparation outside the exam room. Candidates should study Photovoltaic Systems, OSHA, and Ugly's Electrical References before test day and develop enough understanding to answer related questions without those books available.

Licensing Steps

The C-2G trade examination is part of the Nevada contractor licensing process. Applicants must complete the applicable application, qualification, examination, and licensing requirements before a contractor license is issued.

1. Confirm the C-2G classification. Make sure the Photovoltaics subclassification matches the work the business intends to perform.
2. Identify the qualifying individual. The application must identify the person responsible for meeting the trade qualification requirements.
3. Document qualifying experience. Prepare the experience information required for the requested contractor classification.
4. Submit the Nevada contractor license application. Complete the applicable application and supporting documentation.
5. Receive examination eligibility. The qualifying individual can schedule the required examinations after the application is filed and examination eligibility is issued.
6. Prepare for the C-2G trade examination. Study photovoltaic systems, electrical code requirements, calculations, equipment, installation, safety, and interconnection topics.
7. Prepare for Nevada Business and Law. Nevada contractor applicants must also satisfy the applicable Business and Law examination requirement unless an authorized waiver applies.
8. Complete the required examinations. Take the applicable trade and business examinations.
9. Complete remaining licensing requirements. Finish the additional state requirements associated with issuance of the contractor license.

State Requirements

The Nevada C-2G Photovoltaics classification covers the installation, alteration, and repair of photovoltaic cells, batteries, and inverters used in the conversion of solar energy into electricity.

The scope does not include installation, alteration, or repair of electrical wires beyond the service panel. Candidates should understand this limitation because contractor classifications define the work a license holder is authorized to perform.

The C-2G examination tests both photovoltaic-specific knowledge and electrical knowledge. Solar equipment must function as part of an electrical system, so candidates should understand how photovoltaic generation, inverters, batteries, conductors, protective devices, grounding, and electrical interconnections work together.

Nevada contractor licensing also includes requirements outside the C-2G trade examination. The qualifying individual must complete the applicable application and examination process and satisfy the other licensing requirements associated with the classification.

Photovoltaic Systems, 3rd Edition, 2011, OSHA 29 CFR Part 1926, and Ugly's Electrical References are not allowed in the examination center. These references should be used during preparation to build knowledge that can be recalled during the exam.

Test Information and Study Materials

A strong Nevada C-2G study plan should combine photovoltaic theory, National Electrical Code navigation, calculation practice, installation knowledge, and safety preparation.

Estimating, Calculations, and Design deserves the largest share of preparation because it contains 20 questions. Candidates should practice electrical calculations repeatedly rather than simply reading examples. Work through problems until the necessary formulas and steps become familiar.

Electrical Interconnection accounts for 15 questions. Candidates should know how photovoltaic equipment connects to electrical systems and how code requirements affect conductors, disconnects, grounding, bonding, overcurrent protection, and system interfaces.

Photovoltaic Components also accounts for 15 questions. Study the function and relationship of modules, arrays, batteries, inverters, charge-related equipment, disconnecting means, conductors, protective devices, and mounting components.

Photovoltaic Installation includes 10 questions. Candidates should understand system layout, component placement, wiring, mechanical installation, electrical connections, equipment protection, and practical considerations involved in completing a photovoltaic installation.

Photovoltaic Theory should include basic solar-electric principles, voltage, current, power, module and array relationships, and the way environmental and system conditions affect photovoltaic output.

Permitting, Inspection, and Utility Interconnections should include the role of inspections and the relationship between photovoltaic systems, electrical requirements, and utility interconnection processes.

Safety should be studied using OSHA 29 CFR Part 1926 along with practical photovoltaic knowledge. Solar installations can involve electrical exposure, elevated work, ladders, rooftops, tools, lifting, and construction-site hazards.

NEC navigation should be practiced under timed conditions. Instead of reading the code from beginning to end, identify common photovoltaic subjects and practice locating the applicable articles, sections, tables, and definitions.

The NEC index can be useful, but candidates should also understand the organization of the code. Knowing where broad topics are located can save valuable time during an open-book examination.

Permanent tabs can help organize commonly used NEC sections. Since the examination allows approved permanent tabs, candidates can create an efficient navigation system before test day. The goal should be quick access rather than excessive tabbing that makes the book harder to use.

Practice questions should be completed with the NEC nearby so candidates can develop judgment about when to answer from knowledge and when a code lookup is necessary. If every question results in a lengthy search, additional code-navigation practice is needed.

The study-only references should be used differently. Photovoltaic Systems can help build conceptual knowledge, Ugly's can support calculation practice, and OSHA can reinforce safety principles. Because these books cannot be taken into the examination center, candidates should convert the information into working knowledge before test day.

A useful study routine is to divide preparation by examination weighting. Spend the most time on calculations and design, electrical interconnection, and photovoltaic components, followed by installation. Then reinforce theory, permitting and inspection, and safety.

Another effective approach is to study the photovoltaic system as a complete path. Begin with solar energy at the module, follow electrical output through the array and associated equipment, review conversion through the inverter, and then examine electrical interconnection and protection requirements.

This system-based approach can make calculations and code requirements easier to understand because each rule is connected to an actual part of the photovoltaic installation.
