2. Take Practice Tests based On The Solar Contractor License

While running a contractor license school, I learned that the biggest difficulty my students faced was that most of them had not taken an exam in years.

  • Some of my students did not finish high school or had immigrated to the United States recently, and were still learning English. 

  • One of the best study tools for them was to use Online Practice Tests. Simulated online tests are based on the state exam. 

Practice Test Questions

If a swimming pool is 20’ by 30’ and filled to a depth of 8’, what is the volume of water to be solar heated?

b. 4,800 cubic yards

c. 33,600 gallons

d. 35,904 gallons

2. As the temperature of a PV module increases, what will happen to the voltage?

a. The voltage will increase

b. The voltage will decrease

c. The voltage will be unaffected

d. It depends on the module design

3. Find Solar License Study Guides

Test questions are great, but relying on them as your only study source is a big mistake. If you are not into reading, you can find C-46 license exam study books in audio or video format.

Practice test questions for the solar license exam do not give you the theory behind what the question is asking you. Use a book or study guide as a reference.

Exam prep books for the solar contractor license cover a wide range of topics.

They can also be incredibly helpful to refresh your memory on core topics you may have forgotten.

Free contractor license study guides often cover just a snapshot of what you need to know.

Invest in yourself and look for study guides that cover topics such as:

4. Contractor Classes

When you see the term “Contractor Classes” you should understand that they are only LAW & BUSINESS classes for construction contractors.

Contractor license schools offer state-specific exam prep classes that cover the basics of construction LAW.

It is essential to understand the distinction between a contractor license and a trade school.

The C-46 license test is for journey-level tradesman who has a solid understanding of the solar installation trade. Contractor classes are not meant to teach you your trade.
