This 60 question practice exam is based on the 12 books approved for the Solar Contractors Trade Knowledge portion of the exam required by Solar Contractor Candidates.  The questions are based on subject matter that is said to be covered on the examination. 

The specific references include:

Building Estimator's Reference Book, Walker's, 28th Edition

Code of Federal Regulations (OSHA) 29 Part 1926

Contractors Manual

Maintenance and Operation of Stand-Alone Photovoltaic Systems

National Electrical Code, 2008

The purpose of this practice exam is to orientate you with the reference books.  It is more important to locate the answer in the reference materials than it is to simply answer the question correctly.  Passing the actual exam administered by the state requires you to know how to use the books.  If used properly, this practice exam will increase your chance of passing the exam the first time.

These are not actual questions from the exam.  Rote memorization of these questions will probably not help you.

Good luck!
