The C-46 license is for solar contractors that specialize in the installation, modification, and repair of solar energy systems.
The solar industry has seen explosive growth over the past 30 years and continues to grow each year as the planet moves toward more sustainable energy alternatives.
Solar energy is generated by the capture of the sun’s rays through devices that convert the energy into electricity that can power a home, business or factory.
As local, state and federal governments move more and more towards offering incentives for homeowners and small businesses to go solar. Contractors that hold the C-46 license will become more in demand.
This article will provide you with every single detail you need to know about C-46 license requirements, the contractor license exam, practice tests, and even how to fill out the California State License application.
"A solar contractor installs, modifies, maintains, and repairs thermal and photovoltaic solar energy systems. A licensee classified in this section shall not undertake or perform building or construction trades, crafts, or skills, except when required to install a thermal or photovoltaic solar energy system" - CSLB.GOV
The C-46 license is the classification required in the state of California for all persons looking to bid on solar panel installation or repair projects where the cost of labor and materials exceeds $500.

In many cases, solar contractors that hold the C-46 license work directly with with homeowners installing and repairing solar panels.
In some cases they act as an RMO for an established solar installation company.
However, they may also function as a sub to a General Contractor or General Engineering Contractor to continually do solar panel design and fabrication work on multiple projects over an extended period of time.
General Contractors oversee that the solar subcontractor has executed their duties in adherence to code as well as to the specific requests of a client.

The Contractors State License Board (CSLB) is the governing body for all contractors in the state of California.
Their sole responsibility is to protect the consumer public and ensure that anyone charging over $500 for construction services is qualified and registered with the state of California.
The C-46 license is issued to contractors by the CSLB.
The CSLB administers applications, exams, and maintains a database of all active and inactive contractor license numbers which are public domain.
When making alterations to a structure built before 1978 solar contractors must know how to contain lead paint if it is present.
Knowing the correct processes and procedures required by the Environmental Protection Agency is critical for those looking to get the C-46 license.
Lead paint can travel miles through the air, rest on soil, and even enter air ducts causing potentially fatal damage to those that come in contact with it.
Solar contractors looking to build a profitable business must position themselves as experts and the authority within their industry.
Contractors must be a source of information for their clients and community if they want referrals and repeat business.

It is critical for solar contractors to be able to follow specific designs and symbols on construction blueprints when making alterations to a structure.
Construction blueprints communicate important information about how a structure has been built as well as what materials are necessary or have been used for its construction.
Being comfortable with construction blueprints is an invaluable skill for all tradesman but is especially important for those looking to get the C-46 license.
To get a C-46 license in California, you must prove a minimum of 4 years journeyman level experience and pass a two part state exam with the Contractor State License Board.
To qualify for an exam date you must meet the the following requirements:
You must also have:
Journey level experience is gained working unsupervised full time for either a solar company, general contractor, union, or directly under someone that holds the C-46 license.
Some Journeyman level tradesman have also completed apprenticeship programs.
A Journeyman level tradesman can perform all the duties associated with his or her trade.
The state will want to see 4 full-time years experience within the last 10 years. The years do not need to be consecutive, but they do need to be 4 years in total.
The following people may be used as Qualifying Individuals to sign off on your experience when applying for the C-46 license:
“Jeff has repaired solar panels” is not descriptive enough.
The CSLB will want to see something like: "Jeff has installed, modified, maintained and repaired solar and photovoltaic systems".
You must be prepared to submit documentation supporting the experience you claim to have.
The Contractors State License Board gives you a few ways that you can prove your experience.
The CSLB receives thousands of applications per month so there is a good chance they won’t document your experience but if you are one of the applicants that get reviewed you will need to be ready to submit something.
The CSLB does not accept pictures of projects.
The time it takes to get your application processed and assigned a test date fluctuates throughout the year.
Typically you can expect:
I have seen some situations where applicants got their test date sooner and some where they got their test date much later.
The most common reasons your application would get held up are:
The Current CSLB fees are:
Having a criminal record in no way stops you from getting a C-46 License.
We have personally helped guys with all types of criminal records obtain multiple licenses.
The key is to be honest on the application, even if the felony or misdemeanor happened years ago and even if it was expunged.
BE 100% HONEST ON THE APPLICATION, because they will see everything anyway when you do fingerprinting. The CSLB handles criminal records on a case by case basis.
Remember, their responsibility is to protect the public. In my experience, they primarily concerned with criminal charges associated with: Fraud, Embezzlement or Forgery
The exam will be:

Some things to remember:
Being prepared is the most important thing you can do in ensuring your success on the contractor license exam.

Be sure to read this before choosing a Contractor License School.
If you don’t have the 4 years required journeyman level experience to obtain a C-46 license, your journey begins here. The solar industry offers unlimited income opportunity.
