ExploreAbout this exam
C&G 2922-34 is the City & Guilds qualification in the Installation and Maintenance of Small Scale Solar Photovoltaic Systems, a Level 3, competence-focused award for people who already work in electrical installation and want to extend their work into grid-connected small-scale solar PV. Candidates typically arrive able to select protective devices, size cables, test circuits and work safely at height, and the qualification builds directly on those skills rather than teaching electrical fundamentals from scratch. Assessment is by multiple-choice examination covering the practical lifecycle of a domestic or small commercial PV job: health, safety and the regulations and notification duties that frame the work; site survey, shading assessment, array and string design, and component selection; mechanical fixing of modules and routing of DC and AC cabling; connection of inverters and distribution of the generated output into the existing installation; and finally commissioning, testing, fault finding and long-term maintenance. Because the awarding organisation's public page for this qualification could not be retrieved when this material was compiled, no verified figures are quoted here for the exam code's question count, duration, pass mark, fee or validity period. Use this page as topic-level revision guidance and confirm every administrative detail with City & Guilds or your approved centre before you book.
What you'll study
About C&G 2922-34 Solar PV preparation
How many questions are on the exam, and how long do I get?
Those figures cannot be confirmed from the material available here: the awarding organisation's qualification page could not be retrieved, so no question count, duration or per-section timing is quoted. Your approved centre holds the current assessment schedule and will tell you exactly how many questions you will face and the time allowed before you book a date.
What is the exam format?
It is a multiple-choice assessment. That format is the only structural detail supported by the available source, so treat any claim about a specific number of papers, sections or item types with caution until your centre confirms it. Practise single-best-answer questions under time pressure rather than essay-style written answers.
What score do I need to pass?
The pass mark is not stated in any source available here and should not be assumed. The awarding organisation sets it and it can change between versions of the assessment. Ask your centre for the current pass criteria for 2922-34 when you enrol instead of relying on figures quoted in forums or older course handouts.
Can I resit if I fail?
The retake policy is not confirmed by the retrievable source, so no number of permitted attempts and no waiting period is given here. Resit arrangements are administered by the approved centre running your course, so ask them directly about resit cost and how soon a second attempt can be scheduled.
Do I need to be a qualified electrician already?
Formal entry requirements are not verifiable from the material available here. The content does assume working knowledge of electrical installation, because array design, inverter connection and system testing all build on protective earthing, cable selection, discrimination and correct use of test instruments. Check the current entry requirements with your centre before enrolling.
How difficult is the exam?
Candidates most often struggle with the electrical science and design calculations: string voltage at extreme module temperatures, current ratings, and voltage drop across both DC and AC sides. Experienced installers frequently underestimate commissioning documentation and test-sequence questions. If you are confident with standard installation calculations and can explain why each test is performed, the safety and installation topics follow naturally.
What order should I study the topics in?
Work through the five areas in sequence. Start with health, safety and regulations, because they frame every later decision. Move to site survey and system design, then mounting and cabling, then connection into the consumer unit and distribution. Finish with commissioning, testing and fault finding, so your earlier design decisions have something concrete to be verified against.
How should I prepare for it?
Read the current edition of BS 7671, the IET Code of Practice for Grid Connected Solar PV Systems, and the MCS installation standards your work will be judged against. Then drill calculation questions on array sizing, string configuration and cable selection, and rehearse the commissioning test sequence aloud. Finish with timed multiple-choice practice so recall is fast, not just accurate.
Does the exam cover battery storage or EV charging?
The qualification title is limited to small-scale solar PV, so storage and EV charging are not core topics; where hybrid inverters or storage-ready systems appear, they are usually treated as part of the PV installation they serve. Confirm the current syllabus scope with your centre before assuming a topic is, or is not, examinable.
