Renewable-energy technician practice questions

About this practice suite

This suite prepares candidates for renewable-energy technician selection in the energy, utilities, nuclear, mining, and natural resources sector with 5 skill areas: electrical reasoning, technical reasoning, safety judgment, numerical reasoning and situational judgment. Every question was written by Novus editors for this suite (none are taken from live or leaked exams), and the full bank holds 52 scored questions across three modes, plus 8 reserve questions used to vary repeat attempts. Answer keys never ship to the browser: your answers are scored server-side, and results stay on your device.

Skills this suite practises

• Electrical reasoning: Basic circuits, current, voltage, resistance, symbols, and electrical troubleshooting.
• Technical reasoning: Applied technical principles, diagrams, tools, systems, measurements, and troubleshooting.
• Safety judgment: Hazard recognition, safe sequencing, escalation, and risk controls.
• Numerical reasoning: Arithmetic, fractions, percentages, ratios, rates, estimation, word problems, and number relationships.
• Situational judgment: Evaluating workplace responses against role-relevant principles.

Sample questions from the guided bank

Two of the 10 guided-practice questions, shown exactly as they appear in a session. Answers and explanations are not printed here, because keys stay on the server. Open guided practice to answer them and see how you did.

1. A renewable-energy technician primarily:

   • A. Designs national energy policy alone
   • B. Trades carbon credits full-time only
   • C. Installs, commissions, and maintains solar, wind, storage, and related balance-of-plant systems
   • D. Operates underground longwalls

2. Inverter shows ground-fault alarm on a PV array after rain. What is best?

   • A. Hose the inverter while live
   • B. Keep resetting until it stays on
   • C. Bypass GFDI permanently
   • D. Isolate per procedure, inspect for moisture/insulation faults, and clear before reset cycles

Practice modes and timing

Guided practice is untimed-feeling and instructional; the mini-test is a short timed check; the full simulation mirrors a complete sitting. All three draw on separate question sets, so moving up a mode never repeats what you practised.
