Sample questions
01What is the typical efficiency range for monocrystalline silicon solar panels?
- A12-15%
- B15-18%
- C22-26%
- D18-22%
Why: Modern monocrystalline silicon panels typically achieve 18-22% efficiency.
02Which solar cell technology offers the highest efficiency but at higher cost?
- ABifacial modules
- BPolycrystalline silicon
- CMonocrystalline
- DThin-film silicon
Why: Monocrystalline technology offers the highest efficiency among standard commercial technologies.
03What is the main advantage of thin-film solar panels over crystalline silicon?
- ASmaller installation footprint
- BLonger product warranty
- CHigher peak efficiency
- DLower manufacturing cost
Why: Thin-film panels have lower manufacturing costs and a better high-temperature coefficient, though their efficiency is lower than crystalline silicon.
Common questions
Is the Solar PV mock exam free?
Yes — 100% free, no sign-up needed. Questions are pulled at random from a substantial bank, with a worked explanation on every question after you submit.
Can I retake the mock exam?
Yes. Every attempt picks a different random selection and reshuffles the options, so each retake gives you genuinely new questions. No limit on retakes.
Does this count towards the real qualification?
No — this is independent practice material. To gain the actual qualification you need to sit the official assessment through an approved provider.
