Sample questions
01What is the typical efficiency range for monocrystalline silicon solar panels?
- AAround 10-12%
- BAround 15-17%
- CAround 30-35%
- DAround 20-23%
Why: Modern monocrystalline modules typically achieve around 20–23% efficiency at standard test conditions.
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, it is free with 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 as a qualification?
No. This is independent practice material and does not award a qualification, card or certificate. Where a subject has a formal qualification or card, you gain it through an approved provider.
