Assessment criteria
Topic Overview
The GQA Level 2 NVQ Diploma for the Installation of Photovoltaic Panels is a vocational qualification designed for individuals working in the construction industry who wish to specialise in solar photovoltaic (PV) systems. This diploma covers the practical skills and theoretical knowledge required to install, commission, and maintain PV panels on domestic and commercial properties. It is a competency-based qualification, meaning you must demonstrate your ability to perform tasks to industry standards in a real or simulated work environment.
This qualification is essential for anyone pursuing a career as a solar PV installer, as it ensures you understand key principles such as electrical safety, system design, mounting structures, and grid connection. It aligns with the UK's Building Regulations and the Microgeneration Certification Scheme (MCS), which is often required for installers to be eligible for government incentives like the Smart Export Guarantee. By completing this NVQ, you will be equipped to work safely and efficiently, contributing to the UK's renewable energy targets.
The diploma is part of the wider Construction & Building Services sector, specifically within the electrical and renewable energy pathway. It builds on basic electrical knowledge and health and safety practices, preparing you for more advanced qualifications or supervisory roles. The course typically involves on-site assessments, portfolio building, and knowledge tests, ensuring you can apply theory to real-world installations.

Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for accurately identifying the regulatory bodies and specific regulations (e.g., Control of Asbestos Regulations 2012) relevant to asbestos removal.
- Credit for explaining the risk of fibre release when cutting/breaking and the correct technique to avoid disturbance.
- Points for describing the step-by-step procedure from discovery to notifying a supervisor, isolating the area, and securing the site.
- Mark for detailing the storage requirements such as using labelled, sealed containers and designated secure areas.
- Credit for stating the circumstances under which a licensed contractor is legally required and the consequences of non-compliance.
- Award credit for demonstrating knowledge of the Control of Asbestos Regulations 2012 and the ability to source current HSE guidance on handling asbestos cement.
- Award credit for explaining how to identify asbestos cement through visual cues, reference to building dates, and consultation of the asbestos register, and for emphasizing the critical requirement not to cut or break the material.
- Award credit for accurately describing the sequence of actions: immediate stoppage of work, isolation of area, erection of safety barriers and warning signs, and dampening of material to reduce fibre release.
- Award credit for correctly differentiating between non-licensed tasks (removal of asbestos cement under controlled conditions) and notifiable non-licensed/licensed tasks (removal of AIB), and knowing when to halt work and await a licensed contractor.
- Award credit for detailing proper storage procedures: double-bagging in UN-approved bags, labeling, placing in a lockable sealed skip, and arranging transport via a licensed waste carrier with appropriate documentation.
Assessment Guidance
Guidance for achieving higher grades
- 💡Reference the specific Health and Safety Executive (HSE) guidance and approved codes of practice in written responses.
- 💡When describing the removal process, always begin with initial discovery and end with safe disposal, highlighting the role of supervision and licensed contractors at the appropriate stages.
- 💡For practical assessments, demonstrate a cautious approach: don PPE, check the asbestos register, and verbally explain each step before acting.
- 💡Ensure you can distinguish between asbestos cement, which may be removed by trained non-licensed workers under certain conditions, and higher-risk materials that require a licensed contractor.
- 💡Always reference the Control of Asbestos Regulations 2012 and the corresponding Approved Code of Practice in your answers to demonstrate regulatory awareness.
- 💡When describing procedures, use a step-by-step approach starting from discovery to final disposal, highlighting the stop, assess, manage sequence.
- 💡Emphasize the hierarchy of control: avoidance, then non-licensed work with controls, then licensed work; and know when each applies.
- 💡In practical assessments, always verify the asbestos register and company paperwork before commencing any work; this is a key competency check.
- 💡For written answers, clearly distinguish between asbestos cement, AIB, and other forms, as mixing them up is a common reason for failure.
- 💡Tip 1: Always reference the latest edition of BS 7671 and the MCS Installation Standards in your written answers and practical assessments. Examiners look for up-to-date knowledge of regulations.
- 💡Tip 2: When demonstrating practical tasks, focus on safe isolation and lock-off procedures. Many candidates lose marks by rushing the safety checks before starting work.
- 💡Tip 3: In your portfolio, include clear photographs of each installation stage with annotations explaining what you did and why. This shows you understand the process, not just that you can follow instructions.
Common Mistakes
Common errors to avoid in your coursework
- Assuming that asbestos cement poses no significant risk and can be handled without specialized precautions.
- Neglecting to check the asbestos register or company paperwork before commencing work, leading to accidental disturbance.
- Attempting to snap or saw asbestos cement sheets to fit them into waste bags or skips.
- Failing to install a full barrier system, using only warning tape without physical exclusion.
- Misunderstanding that all asbestos-containing materials require a licensed contractor, leading to unnecessary delays or incorrect handling of low-risk asbestos cement.
- Failing to dampen asbestos cement before removal, increasing the risk of fibre release.
- Neglecting to consult the building's asbestos register and relying solely on visual inspection, which can miss hidden asbestos.
- Storing asbestos waste in single bags or unlabeled containers, breaching hazardous waste regulations.
- Attempting to remove asbestos insulation board without recognizing its higher risk and the legal requirement for a licensed contractor.
- Misconception: Solar panels work best in hot weather. Correction: PV panels actually perform more efficiently in cooler temperatures; excessive heat can reduce voltage output. Sunlight intensity, not heat, is the key factor.
- Misconception: You can install PV panels without notifying the Distribution Network Operator (DNO). Correction: For systems over 3.68 kW (single-phase) or 11.04 kW (three-phase), you must obtain DNO approval to ensure grid stability and compliance with G98/G99 regulations.
- Misconception: All inverters are the same. Correction: Inverters come in different types (string, micro, hybrid) and must be matched to the system size, shading conditions, and battery storage requirements. Choosing the wrong inverter can reduce efficiency or void warranties.
