OSHA safety courses and certification programs are designed to prevent injuries and promote safety on job sites. In particular, the OSHA 10-Hour for the Construction Industry course is popular with solar panel installers and covers hazard identification, avoidance, control, and prevention at construction sites. It examines personal protective equipment and the safe use of tools. Also, many OSHA safety courses are available online, eliminating the need to travel.

Solar Installer Contractor Licenses

Each state issues these licenses, and the requirements vary. Solar PV installations must adhere to the National Electrical Code requirements, so some electrical knowledge is required. There are usually different levels of licensed electricians, such as master electricians, journeymen electricians, and helper electricians. Becoming a licensed electrician typically requires passing a written exam and completing a certain number of hours of relevant experience.

Licensing requirements for solar PV installations vary by state. The Interstate Renewable Energy Council (IREC) has a national solar licensing database with information on each state's requirements.

Frequently Asked Questions On Solar Installer Certifications

In this section, we’ll cover some of the most frequently asked questions about certifications for solar installers.

Should I Hire a Certified Solar Installer?

Yes, hiring a certified solar installer is a good idea for homeowners and solar companies alike. Certified solar technicians have the expertise to design, install, and maintain solar systems safely and efficiently. They understand local regulations and solar permitting requirements, ensuring compliance. A certified installer understands the proper functioning of solar power systems, maximizing energy production and return on investment.

Why Are Solar Installer Certifications Important?

Unfortunately, not all solar energy technicians are reputable or understand solar installation basics and the National Electrical Code. NABCEP solar installer certification allows PV contractors to distinguish their knowledge to customers to earn trust. Solar companies will often display the NABCEP-certified PV installation Professional logo on solar proposals, the company website, on solar RFP responses

In addition, motivated individuals can advance their careers and differentiate themselves from other job applicants by obtaining solar installer certifications. For example, it’s ideal for lead solar installers to have earned NABCEP certification.

How Can I Verify If a Solar Installer is Certified?

You can verify a solar installer's certification by checking with the certifying organization. Most solar installation certification programs have public directories or websites where you can search for certified professionals by their name or location. These directories or websites provide a reliable source of information to confirm a solar installer's certification status.

What Are The Similarities And Differences Of Solar Installer Certifications Vs. Licenses?

States require licensing to perform certain types of work, whereas solar certifications are voluntary. State and local governments created contractor licenses to impose specific standards and protect consumer safety.

Unfortunately, many licenses are limited to a particular state. Unfortunately, this makes it difficult for solar installers to move or perform work out of state because their license may not be valid elsewhere. One benefit of NABCEP certification is that it is nationally recognized and is not limited to a specific state or locality.

How Do I Become a Certified Solar Installer?

NABCEP offers several solar installer certifications that are widely recognized throughout the solar industry, including the PV Installer Specialist and the PV Installation Professional Board Certifications. Each solar certification requires 10 hours of OSHA construction industry safety training, taking solar energy training, passing a written exam, and meeting the solar installation experience requirements.

How much does NABCEP solar installer certification cost?

There are various fees associated with becoming a NABCEP-certified solar professional.

What Is The Difference Between NABCEP’s PVIP & PVIS Solar Certification?

The PVIP certification has been around much longer and requires a broader range of knowledge, including maintenance and commissioning. It also has a greater training requirement and is a good idea for a lead installer or the owner of a PV company. By contrast, the PVIS solar certification focuses just on the installation phase of solar power projects and has a lower training requirement.

However, there are also many similarities. The exam covers similar information related to solar installation, and they both require an OSHA 10 card and solar industry experience. Also, both PVIP and PVIS certifications are available through NABCEP.

Is the NABCEP Exam Difficult for Solar Installers to Pass?

Historically, pass rates for NABCEP exams have generally been lower than some other professional exams, reflecting the rigor of the certification process. To increase their chances of success, you can take NABCEP-approved training courses, review relevant study materials, take a practice exam, and participate in practical, hands-on experience.

Which NABCEP Solar Panel Installation Certification is Best?

The best certification depends on your specific role and career objectives within the renewable energy sector. For example, if you are primarily involved in installing solar panels, the PV Installation Professional certification may be most relevant. If you focus on designing solar PV systems, the PV Design Specialist certification may be a better fit.

How Often Do Solar Installers Certifications Need To Be Renewed?

NABCEP certifications are valid for several years and then require recertification. The PVTS, PVIS, and PVIP certifications must be renewed after three years and have additional continuing education training requirements.

Are There Solar Installer Training Courses I Can Take?

NABCEP, the SEI, IREC, Grid Alternatives, trade schools, and community colleges offer a variety of solar installer training classes. Some of these training programs are available online and don't require travel, but some are in-person classes with hands-on experience. Many of these solar installer training programs are helpful in earning solar installer certifications through NABCEP.

How Can Solar Installer Certifications Shape Hiring New Employees?

Solar company owners may struggle to find qualified solar installers and often need to train new hires. Applicants with related certifications distinguish themselves from other candidates by showing a certain amount of knowledge and experience.

Also, having employees with solar installer certifications can help PV companies stand out from competitors by going above and beyond what is required. Unfortunately, NABCEP-certified solar installers are in high demand but are often difficult to find. Often, companies pay for their employees to become NABCEP-certified solar installers or salespeople.

Another helpful strategy when hiring new employees is to look for trades professionals with related experience. For example, roofers often have transferable skills and are likely comfortable working at higher heights. Certified electricians already have electrical knowledge, credentials, and expertise. This experience may make it easier to train new hires and turn entry-level installers into experts more quickly.

Solar Installer Certifications Can Advance Careers & PV Companies

Many of the most recognized solar installation companies have technicians with NABCEP solar certifications and meet the licensing requirements set by their states. Obtaining this credential or hiring employees who are NABCEP-certified is an excellent way to earn the trust of potential customers and build a name as a reputable solar company.
