How to Inspect Your Solar Panels in Newcastle, NSW

The Importance of Solar Panel Inspections in Newcastle, NSW

Newcastle and the broader Hunter Region boast a climate that is exceptionally well-suited for solar energy generation. However, this same environment exposes rooftop infrastructure to intense ultraviolet radiation, severe coastal salt aerosol, and heavy industrial fallout. Over time, these environmental stressors can degrade delicate photovoltaic cells, electrical wiring, and mounting hardware. To protect your capital investment and ensure optimal energy generation, regular system inspections are absolutely vital.

If you don’t maintain your solar system, it can reduce its performance. Moreover, neglecting this maintenance can lead to safety hazards. At Waspindustries, we frequently encounter commercial and residential arrays that have been left unchecked for years. In this comprehensive guide, we will outline everything you need to know about inspecting your solar panels in Newcastle. We will explore the critical differences between what a homeowner or renter can safely do versus what requires a licensed professional, the specific types of issues to look out for, and the rigorous safety considerations required for commercial inspections.

Homeowner and Renter Inspections: What You Can and Cannot Do

When a property owner or renter suspects an issue with their energy yield, the immediate temptation is to climb onto the roof to investigate. However, strict safety regulations and physical hazards make this incredibly dangerous.

The Limits of DIY Inspections

Electricity can be dangerous, never attempt to repair electrical issues yourself and conduct visual inspections from the ground. It is imperative that you leave any close-quarters investigation to the experts.

• DO NOT check the solar panels, their wiring or any other part of the system yourself.
• Homeowners should not try to check the installation panels themselves.
• Homeowners should not simply ‘turn off’ their panel systems.
• Solar panel systems need to be shut down according to a specific shutdown procedure.
• Turning off the panels in the wrong way can contribute to problems, not prevent them.

Safe Ground-Level Monitoring

While you cannot physically touch the panels, you play a crucial role in monitoring the system’s health from a safe distance. You should visually inspect your solar power system from the ground.

To keep your system operating at its best, you can check your system’s performance. This involves looking for sudden drops in efficiency that indicate a potential fault.

• Begin by checking the generation levels shown on your electricity bills – look for drastic changes to your energy usage, or your solar feed-in tariff.
• You should also be checking monitoring data for decreased performance.
• Look closely at the equipment itself by checking the data screens on your inverter, or its online interface, for error messages.

If your ground-level visual inspection or billing data raises concerns, it is time to call in a professional. If you have any questions about the safety of your solar PV system, contact the company that sold you the system. Where the company cannot satisfy you that your system is safe, you should ask them to come and inspect it.

What is Included in a Professional Solar Panel System Inspection?

When it comes to physically diagnosing and servicing your array, specialised qualifications are non-negotiable. Only use an appropriately qualified professional, such as a licensed electrician, an installer accredited by Solar Accreditation Australia or a New Energy Tech Consumer Code (NETCC) approved seller to perform close-quarters inspections of your system or when inspections require going onto your roof.

Electrical Safety and Compliance

After your solar panels are installed, a licensed electrician must check that your system is safe. Once this is completed, the electrician must give you a Certificate of Compliance for Electrical Work (CCEW). This document is your proof that the system complies with strict Australian safety standards. You can check a licence online or call the Building Commission NSW on 13 27 00.

The Inspection Process

A professional inspection goes far beyond a simple glance at the glass. Maintenance that involves electrical work or electrical installation must be performed by a licensed electrician. During a comprehensive service, the licensed professional will execute a strict checklist to ensure total operational safety.

• The electrician will visually check the fittings and cables at the panels and the inverter haven’t broken loose.
• They will review the inverter display panel for any recorded faults.
• They must check that emergency procedures for shut down and isolation are clearly displayed.
• The inspector will make sure that the cooling vents of the inverter are clear of debris.
• They will ensure easy access to the system isolator switches.

If any hardware is compromised, any damaged panels or damaged other parts of the solar PV system should be repaired or replaced by a licensed electrician before cleaning occurs.

Types of Issues You Are Looking For

Both homeowners (from the ground) and professionals (on the roof) are hunting for specific environmental and mechanical failures. Over time, overhanging trees, dust and debris, and storm damage can all take their toll on solar panels, wiring and control systems.

1. Debris and Shading: In Newcastle, salt spray and industrial dust quickly accumulate. This shading can significantly reduce efficiency.
2. Water Ingress: Severe storms and East Coast Lows can force moisture into the system. There may be risks to your system due to residual moisture or damage to the inverter.
3. Physical Damage: Hail and flying branches can cause micro-fractures in the photovoltaic glass, leading to total panel failure.
4. Cleaning Hazards: When it is time to remove debris, a competent person should use water, not cleaning products. They must not use scourers or other abrasive cleaners. Furthermore, they must avoid using high pressure water cleaners and not rest buckets or lean on the panels. At Waspindustries, our pure-water soft wash systems align perfectly with these strict industry guidelines, ensuring safe and effective cleaning.

Considerations for Commercial Versus Residential Inspections

While the core technology remains the same, the scale and risk profile of a commercial solar inspection drastically differ from a standard residential check. Residential systems are generally smaller and more accessible. Commercial systems, however, are massive logistical undertakings that often span multi-story warehouses.

Height Safety and Workplace Compliance

The installation of rooftop solar panels, if done unsafely, can put workers at risk of falls from heights, contact with electricity, exposure to asbestos, being hit by falling objects (e.g. panels) and musculoskeletal injuries. Because of this, commercial inspections are heavily regulated by SafeWork NSW.

Before any commercial inspection or maintenance work can begin, the contracting company must prepare, with consultation from workers, a safe work method statement (SWMS) for each job when: the risk of falls is two metres or more. Commercial facility managers and solar retailers must verify their installer is working safely, checking they have appropriate qualifications and licences, a workers compensation policy, and a safe systems of work and safety equipment.

Furthermore, when mitigating fall risks on massive commercial roofs, professionals must use higher order controls, such as roof guard rails, before considering lower order controls, such as fall restraint or arrest (harnesses).

Key Features of Proper Solar Inspections

• Safety First: Ensuring all inspections are safely executed from the ground by homeowners, leaving roof access entirely to licensed professionals.
• Documentation: Verifying that a Certificate of Compliance for Electrical Work (CCEW) is present and provided to the network operator.
• Strict Procedures: Adhering to the rule that solar PV systems need to be shut down according to a specific shutdown procedure.
• WHS Compliance: Executing strict SafeWork NSW guidelines, including SWMS and fall protection, for all commercial-scale inspections.

Frequently Asked Questions
