(it is important that you put anything here, since they already know about it and if they catch you lying, it would disqualify you, whereas if you tell the truth, you will appear to have learned an important lesson).

Here is a link to various guides and documents that you should order (they will mail them to you for free). This will help you study for the exam & let you know more about the process. This is required reading for the class.

Also, do not worry about the Asbestos open book examination. Once you pass your exam, you will get to take an open book examination & all of the answers are in the back of the book.

Here is what you will get once you are a California Licensed Solar Contractor:

It is the only Government Sanctioned Solar License that I know about & is a good credential to have in the industry. Also, getting NABCEP certified is another good goal to accomplish.

If you haven't already heard, the C46 license exam has more solar thermal than it does PV (solar electric). There are more questions on the exam about plumbing, than there are about electricity.

Another good & free resource for learning about Solar Hot Water (SHW) is the Pacific Energy Center. The have a SHW class coming up that is not full yet. The course is given online & in person. Find them at:

Here are some practice questions:

Next weeks quiz will be exact questions from the practice questions above. This is an exercise in memorizing multiple choice questions, which is how most people pass contractors license exams.

Here is a mobile study guide:

One of the best ways to assimilate extraneous information is to input it into your subconscious on an ongoing basis, not necessarily all at once, but throughout the day. Put this in your pocket & every time you have 30 seconds to spare, take in some information.

Notes Week 6 (last class)

The final exam will be taken from all of the other exams and from the practice C46 quiz which we went over on week 5.

The following are downloadable copies of everything that may be on the final.
