• Piping: 10 questions
• System Design: 15 questions
• Pumps and Storage Systems: 5 questions
• Collectors: 7 questions
• System Valves and Controls: 3 questions
• Safety: 5 questions

System Design is the largest subject area with 15 questions. Candidates should spend a substantial portion of their preparation on complete solar thermal system layouts, circulation, storage, heat transfer, collector relationships, pumps, valves, and controls.

Piping represents 10 questions and is one of the most important areas for use of the Uniform Plumbing Code. Candidates should be comfortable locating requirements involving pipe materials, fittings, supports, joining methods, routing, and related plumbing provisions.

Collectors accounts for 7 questions, while Pumps and Storage Systems and Safety each account for 5 questions. System Valves and Controls represents 3 questions.

Because candidates have 1.5 hours for 45 questions, they have approximately two minutes per question on average. Efficient use of the Uniform Plumbing Code can help preserve time for questions that rely on practical solar thermal knowledge.

Open Book Test

The Nevada C-37 Solar Contractor examination is an open-book test.

The reference allowed into the trade examination and included in this package is:

• Uniform Plumbing Code, 2018

The Uniform Plumbing Code should be used regularly throughout preparation. Candidates should become familiar with the book's overall organization, table of contents, index, definitions, tables, exceptions, and cross-references.

Open-book testing does not mean every answer can be found quickly without preparation. Candidates who know where to look can use the code more efficiently than those who attempt to search the entire book for each question.

For piping-related questions, first identify the technical subject. The question may involve pipe materials, supports, fittings, connections, valves, or another plumbing requirement. Once the subject is identified, use the index or table of contents to narrow the search.

Questions involving system design, collectors, pumps, storage, or safety may rely more heavily on retained trade knowledge. Candidates should therefore use the Uniform Plumbing Code as a targeted reference rather than expecting it to replace broader solar thermal preparation.

Licensing Steps

1. Confirm the C-37 classification. Make sure the Solar Contractor classification matches the type of solar thermal contracting work the business intends to perform.
2. Identify the qualifying individual. The contractor application must identify the individual responsible for satisfying the applicable qualification requirements.
3. Prepare qualifying experience information. Organize the work-history documentation required for the C-37 classification.
4. Submit the Nevada contractor license application. Complete the applicable application and supporting documentation.
5. Receive examination eligibility. After applicable qualification and application requirements are addressed, proceed with required testing.
6. Prepare for the C-37 trade examination. Study piping, system design, pumps and storage systems, collectors, valves and controls, and safety.
7. Practice Uniform Plumbing Code navigation. Use the 2018 UPC regularly so code lookups become faster and more familiar.
8. Prepare for Nevada contractor business requirements. Complete the applicable contractor business and law preparation required for Nevada licensing.
9. Complete required examinations. Take the applicable trade and business examinations.
10. Complete remaining licensing requirements. Finish the other applicable requirements associated with contractor license issuance.

State Requirements

Nevada identifies C-37 as the Solar Contractor classification. The classification covers the design, fabrication, and installation of systems for the collection of solar energy to heat and cool water, air, and chemicals.

The C-37 classification is focused on solar thermal systems rather than photovoltaic electrical generation. Candidates should concentrate on the practical systems that use solar energy to transfer heat through water, air, or other working media.

Solar thermal contracting work can involve collectors, piping, storage, pumps, valves, controls, heat-transfer systems, and related components. The examination reflects this broad technical scope.

Candidates should understand how these components function individually and how they work together as a complete system. A strong preparation plan should connect code knowledge with practical installation principles rather than studying each subject in isolation.

The C-37 trade examination is one part of Nevada contractor licensing. Applicants must also satisfy applicable qualification, application, financial, business, and other licensing requirements before a contractor license is issued.

Reference Books

• Uniform Plumbing Code, 2018
  This exam-room-approved reference supports preparation involving piping systems, pipe materials, fittings, supports, valves, connections, water systems, and other plumbing code requirements that can apply to solar thermal installations.

Exam Room Approved Books

• Uniform Plumbing Code, 2018
  This is the exam-room-approved reference included in the Nevada Solar Contractor (C-37) Books Allowed into Exam Package. Candidates should practice locating piping, material, support, fitting, connection, valve, and related plumbing provisions before test day.

Test Information and Study Materials

A strong Nevada C-37 preparation strategy should begin with System Design because it represents 15 of the 45 examination questions. Candidates should understand how solar thermal collectors, piping, pumps, storage, valves, controls, and heat-transfer components work together.

Review complete system layouts rather than memorizing isolated components. Candidates should be able to follow the movement of heat from the collector through the circulation system and into storage or the final heating application.

Piping is another major subject with 10 questions. This is one of the most important areas for Uniform Plumbing Code navigation. Candidates should become familiar with pipe materials, fittings, supports, joining methods, routing, and installation requirements.

Practice locating plumbing requirements by subject. For example, begin with a question about pipe material and use the index to find the appropriate section. Repeat the same exercise with fittings, supports, valves, and connections.

The Uniform Plumbing Code, 2018 should be used throughout preparation rather than only during the final days before the examination. Regular use helps make the structure of the book more familiar.

Definitions can be especially important. A question may depend on the specific code meaning of a plumbing term, and locating the definition can help determine which section applies.

Tables should also receive attention. Important plumbing requirements may appear in tables, and candidates should practice reading headings, notes, conditions, and related references carefully.

Exceptions can modify a general rule. Candidates should read enough surrounding code language to identify exceptions or special conditions before selecting an answer.

Cross-references may direct the candidate to another section containing additional requirements. Practice following these references instead of assuming the first section contains the complete answer.

Collectors represents 7 questions. Candidates should understand the basic purpose of solar thermal collectors and how they transfer solar energy into a working fluid or thermal system.

Review collector arrangement, mounting concepts, orientation, circulation, and the relationship between collector placement and system performance.

Pumps and Storage Systems represents 5 questions. Candidates should understand how pumps circulate fluids through a solar thermal system and how storage allows collected energy to be used when needed.

Review circulation principles, pump placement, storage tanks, heat exchangers, and the relationship between system demand and stored thermal energy.

System Valves and Controls accounts for 3 questions. Review the purpose of shutoff valves, check valves, balancing devices, temperature controls, differential controls, and other system components that regulate operation.

Safety represents 5 questions. Candidates should prepare for practical jobsite safety involving ladders, elevated work, roof access, tools, piping, hot surfaces, electrical control components, lifting, and other installation hazards.

Because this package contains only the exam-room-approved Uniform Plumbing Code, candidates should make sure their broader study plan also covers system design, collectors, pumps, storage, controls, and safety.

Heat transfer is a useful core concept for solar thermal preparation. Candidates should understand how energy collected from sunlight is transferred into a working fluid and then moved to storage or another heating application.

System balance should also be studied. Proper fluid movement through collectors can affect system performance, so candidates should understand the basic purpose of balanced piping and controlled circulation.

Freeze protection is another practical area worth reviewing. Solar thermal components can be exposed to outdoor conditions, so system design must account for environmental temperatures and appropriate protection methods.

Insulation is important because heat can be lost through exposed piping. Candidates should understand why solar thermal piping is insulated and how heat loss can affect system performance.

Expansion should be considered in systems exposed to high temperatures. Hot piping can expand, so supports, materials, and system design must account for thermal movement.

A useful study schedule is to divide preparation according to the exam outline. Spend the most time on System Design and Piping, followed by Collectors, Pumps and Storage Systems, Safety, and System Valves and Controls.

Once each area becomes familiar, move into mixed-question practice. The actual exam can shift quickly from a piping requirement to a system-design question or collector concept.

Timed lookup drills are especially useful because candidates have approximately two minutes per question. Choose a plumbing topic and practice locating the relevant UPC section within a limited amount of time.

Do not depend on finding every answer in the book. Some questions will be better answered through retained trade knowledge, while the UPC should be used for targeted confirmation of code-based requirements.

When a practice question is missed, identify the cause. The issue may be weak trade knowledge, unfamiliar terminology, slow code navigation, or difficulty connecting multiple system components.

Correcting the underlying weakness is more valuable than memorizing a single answer. This creates stronger preparation for unfamiliar questions on the actual examination.

Time management should also be practiced. Answer familiar questions efficiently, use the UPC for targeted lookups when necessary, flag difficult items, and return to them after completing questions that can be answered more quickly.
