SOLAR PV INSTALLER
Installs photovoltaic systems on roofs and ground mounts. Growing trade, often a stepping stone to electrician. Missouri is not a right-to-work state — union density is higher than average and prevailing wage rules cover most public projects.
The License.
Most states issue a journeyman license (allows you to work under a licensed contractor) and a separate master or contractor license (allows you to pull permits and run your own business). The journeyman license typically requires completing your apprenticeship and passing a written exam; the master/contractor license requires additional field hours — usually 2 years as a journeyman — and a separate exam.
Requirements in Missouri: confirm current hour and exam requirements directly with Missouri Office of Statewide Electrical Contractors. Rules update frequently and our data reflects published standards as of early 2025.

The Exam.
Most states use the NEC (National Electrical Code) as the basis for the journeyman and master electrician exam. Missouri may be on a different NEC edition than the current one — confirm which edition before you study. Pass rates vary significantly: some states run 50–60% first-time pass rates, others run higher. PSI Exams and Prometric administer most state electrical exams. Bring your NEC codebook (tabbed) where allowed. Prevailing wage requirements in Missouri apply to most public-sector projects, which ties exam and licensure to wage scale compliance for contractors.
Be honest about pass rates. Many licensing boards do not publish them. When they do, first-time pass rates for journeyman exams in the trades typically run 50–75%. Preparation time varies — most serious candidates spend 60–120 hours on exam prep. Use code books from the correct edition, not what's currently in print.
