From the NABCEP website:

The NABCEP Associate Program recognizes individuals who have demonstrated knowledge of the fundamental principles of the application, design, installation, and operation of Photovoltaic, Solar Heating or Small Wind energy systems. 

The intent of certification is to provide consumers with assurance that their renewable energy system provider has familiarity and experience with the system(s) they are installing. Mike at Green Prepper is committed to a program of continuing education that will complement his experience in the field for years to come.
