Terms & Conditions

SunWise Solar Cleaning — Terms & Conditions

Last updated: September 2026

These Terms & Conditions apply to all services provided by SunWise Solar Cleaning (“SunWise”, “we”, “us”, “our”) to any customer (“you”, “your”, “the client”). By accepting a quote, booking a service or giving us access to your property, you agree to these terms.

1. Our Services

SunWise provides professional services to residential, commercial and industrial clients, including:

• Solar panel cleaning

• Lichen treatment and removal

• Solar system health checks

• Roof cleaning (pressure cleaning)

• Gutter cleaning

• Exterior pressure cleaning (driveways, paths and other suitable surfaces)

• Bird proofing

The exact scope of each job is set out in your quote or booking confirmation. Work outside that scope is not included unless we agree to it in writing.

2. Solar Panel Cleaning

2.1 Solar cleaning uses professional solar-specific equipment, soft brushes and purified (de-ionised) water designed for solar panel surfaces. We do not use high-pressure washing directly on solar panels.

2.2 Solar cleaning removes surface contamination such as dust, dirt, pollen, salt, bird droppings and organic build-up. It does not repair, adjust or maintain any part of your solar system.

2.3 Lichen treatment. Heavy lichen is treated with specialist products and is charged separately from a standard clean unless your quote says otherwise. Lichen is often firmly attached to the panel surface and frame. Some lichen, residue or staining may remain after treatment, may take several weeks to fully break down, or may need more than one treatment. We cannot guarantee complete removal.

2.4 If we arrive and find the level of contamination, the number of panels or the access requirements are materially different from what was quoted, we will tell you and confirm any price change with you before carrying out the additional work.

3. Solar System Health Checks

3.1 What a health check is. A SunWise solar system health check is a visual, non-invasive check of the visible condition and apparent operation of your solar system. It is carried out by a qualified electrician. It gives you an informed snapshot of your system’s condition on the day of service and helps identify issues that may need further attention.

3.2 What a health check may include, depending on the system, access and conditions on the day:

• Visual inspection of panels, frames, clamps, rails, mounting points, visible cabling, connectors, isolators, the inverter and signage, for visible damage, wear, defects or obstructions

• Noting the inverter’s display, status, fault indicators and generation data, and data from the monitoring app where available

• Non-invasive measurements, such as DC current readings taken with a clamp meter around accessible, insulated cables, and solar irradiance readings, taken only where this can be done without opening any enclosure or exposing any live parts

• An estimate of system performance, based on those readings, the panel and inverter specifications, and the weather, irradiance, orientation, tilt and shading on the day

• Before, after, defect and inverter photos

• A written summary of observations and recommendations

3.3 What a health check does NOT include. SunWise does not hold an electrical contractor licence and does not carry out electrical work as part of a health check or any other service. A health check does not include:

• Opening, removing covers from, or working inside inverters, isolators, junction or combiner boxes, switchboards or any other electrical enclosure

• Disconnecting, reconnecting, altering, repairing, replacing or adjusting any electrical equipment, cabling, plugs or connectors

• Any test or measurement that requires contact with, or exposure of, live electrical parts

• Insulation resistance, polarity, open-circuit voltage, earth continuity, IV-curve or other formal electrical testing

• Electrical safety inspections, compliance testing, or certification of any kind (including compliance with Australian Standards or network requirements)

• Rectification of any defect found

3.4 Performance estimates are indicative only. Performance figures in a health check are estimates based on conditions at the time of inspection. Solar output is affected by many variables, including cell temperature, irradiance changes, cloud, inverter efficiency, orientation, tilt, shading, panel age and degradation, mismatch, wiring losses and inverter tracking behaviour. A health check is not laboratory-grade or manufacturer-standard performance testing. It should not be relied on as proof of a warranty claim, system fault or system compliance.

3.5 Limitations. A health check can only assess what is visible and safely accessible on the day. It cannot detect every fault, including concealed wiring faults, internal inverter or panel faults, intermittent faults, or faults that appear under different conditions. A health check does not certify that your system is safe, compliant or free of defects.

3.6 If we find a possible defect or hazard, we will record it in your report and recommend that you contact a licensed electrical contractor or your system installer to assess and rectify it. If we believe a condition may be dangerous, we may stop work, keep clear of the equipment and advise you to arrange a licensed electrical contractor. Arranging and paying for any assessment or repair is your responsibility, and we accept no responsibility for work done by third parties.

3.7 Free and paid health checks. Some cleaning packages or promotions include a basic visual health check at no extra charge. A more detailed paid health check may also be offered. The scope of your health check is the one described in your quote or booking. A health check is not a substitute for periodic maintenance and inspection of your system by a licensed electrical contractor or accredited solar installer.

4. Roof Cleaning

4.1 Roof cleaning is carried out by pressure cleaning, using commercial pressure cleaning equipment with the pressure and technique adjusted to suit the roof type, to remove dirt, mould, moss, lichen and organic build-up from suitable surfaces such as tile and Colorbond roofs. Where heavy growth is present, we may pre-treat it with a cleaning product before pressure cleaning.

4.2 Results. Pressure cleaning removes most surface dirt and growth, but some staining, discolouration, rust marks, efflorescence (white salt deposits on tiles), mineral deposits, lichen marks or ingrained marks may be permanent and may not be removable by cleaning. We do not guarantee that a roof will look new after cleaning.

4.3 Pressure cleaning and your roof. Pressure cleaning can remove loose or failing paint and coatings, surface granules, and loose pointing, bedding or sealant, and water can be forced under tiles, flashings or ridge capping where there are existing gaps or defects. We work with the fall of the roof and adjust our pressure to reduce these risks, but walking on or cleaning a roof can expose existing weaknesses. We are not responsible for:

• Cracked, brittle, porous, loose or broken tiles, or tiles that crack under normal foot traffic because of age or pre-existing condition

• Loss of paint, coatings, granules, pointing, bedding or sealant that was already deteriorated, loose or poorly adhered

• Deteriorated ridge capping, flashings, sealants or skylights

• Water entering the building through existing defects, cracked tiles, gaps, missing pointing, blocked valleys or poorly sealed penetrations

If you know of any leaks, weak areas, previous re-coating or roof defects, you must tell us before work starts.

4.4 We do not provide roof repairs, re-pointing, re-coating or roof restoration unless specifically quoted.

5. Paint, Coatings & Surface Condition

5.1 Painted and coated surfaces, including roof paint, Colorbond finishes, roof membranes, gutters, fascias, eaves, walls, fences, decking and outdoor furniture, deteriorate over time from UV exposure, heat, weathering and age.

5.2 Where a surface is oxidised, chalky, faded, flaking, peeling, poorly adhered, previously repainted, or in otherwise poor condition, cleaning may cause loose or failing paint or coating to lift, flake or come away, and may make existing fading, patchiness or colour variation more noticeable. We do not guarantee that paint or coatings in poor or aged condition will not be affected by cleaning. SunWise is not responsible for paint or coating loss or change caused by the pre-existing condition of the surface.

5.3 If we notice paint or coatings that appear to be in poor condition, we will try to raise it with you before starting. We may adjust our method or recommend not cleaning that area. If you ask us to proceed, you accept the risk described above.

6. Chemicals, Overspray, Runoff & Plants

6.1 Lichen treatment and any pre-treatment products use chemicals that can harm plants, grass and garden beds, and can mark or discolour some surfaces if they come into contact with them.

6.2 Our precautions. Where practical, we pre-wet and rinse surrounding plants, lawns and garden beds before and after chemical application, control application to minimise overspray, and rinse down surrounding areas after cleaning.

6.3 No guarantee. Despite these precautions, wind drift, overspray, runoff, pressure-cleaning spray and water flowing from roofs, gutters and downpipes cannot be completely controlled. We cannot guarantee that plants, lawns, garden beds, trees or surrounding surfaces will not be affected. Sensitive plants may show leaf burn, browning, discolouration or dieback. Plants that are already stressed, potted, newly planted, or located under gutters, downpipes or roof edges are at greater risk. SunWise is not liable for damage to plants or landscaping caused by chemical overspray, drift or runoff, except to the extent caused by our negligence.

6.4 Your responsibilities before a roof clean:

• Move pot plants, outdoor furniture, cushions, toys and pet bowls away from the work area, or tell us about anything that can’t be moved

• Move vehicles, boats and caravans away from roof edges, driveways and the work area

• Close windows, doors and skylights, and keep pets and people (especially children) indoors or away from the work area

• Tell us about ponds, fish tanks, water features, vegetable gardens, rainwater tanks, pools or any other sensitive areas

• Disconnect downpipes to rainwater tanks, or tell us where rainwater tanks are, so runoff does not enter your drinking water supply

6.5 Chemicals may cause marks or discolouration on some surfaces, including certain metals, stone, timber, fabrics, render and painted surfaces. We take care to rinse these areas, but we are not responsible for marks on surfaces or items you have not moved or told us about.

7. Gutter Cleaning

7.1 Gutter cleaning removes accessible leaves and debris from gutters. Unless quoted, it does not include clearing blocked downpipes, underground stormwater pipes, or repairs.

7.2 Old, rusted, corroded, sagging or poorly fixed gutters, brackets and downpipes may be damaged or reveal existing holes or leaks during cleaning. We are not responsible for gutter failure caused by existing condition.

7.3 Some debris or dirty water may fall or overflow onto the ground, walls or surrounding surfaces during cleaning. We will clean up visible debris from the work area where reasonably practical.

8. Exterior Pressure Cleaning

8.1 Pressure cleaning is suited to hard surfaces such as concrete driveways and paths. Some surfaces, including soft or aged pavers, exposed aggregate, sealed or coated concrete, render, timber and painted surfaces, can be marked, etched or have loose material, sealer or coatings removed by pressure cleaning.

8.2 We are not responsible for loss of existing sealer, coatings, loose grout, joint sand or deteriorated surface material. Some stains, such as oil, rust, tyre marks, paint and fertiliser stains, may be permanent.

9. Quotes, Pricing & GST

9.1 All quotes are valid for 30 days unless otherwise stated.

9.2 All prices quoted and invoiced are in Australian dollars (AUD) and include GST.

9.3 Quotes are based on the information available to us at the time of quoting, such as photos, satellite imagery, system size, roof type and contamination level. If conditions on site are materially different, we will discuss any change in price with you before proceeding.

9.4 Any additional work you request on the day will be quoted and agreed before we carry it out.

9.5 Promotional discounts apply only to the services and period stated in the promotion. They cannot be combined with other offers unless stated, and apply to new bookings made during the promotion period.

10.1 Payment is due within 7 days of the invoice date unless otherwise agreed in writing.

10.2 Accepted payment methods are bank transfer, card and approved cash payments.

10.3 A $25 administration fee may apply to each reminder notice we issue for an overdue invoice.

10.4 For commercial jobs, a deposit or progress payments may be required, as set out in your quote.

11. Bookings, Scheduling & Weather

11.1 Bookings are confirmed by email, SMS or phone.

11.2 Work may be rescheduled because of rain, strong winds, extreme heat, storms, or other weather or site conditions that affect safety or cleaning quality. We will tell you as early as possible and give your job priority for the next suitable date.

11.3 Arrival times are estimates, and delays can occur because of weather, traffic or earlier jobs running over.

12. Site Access & Your Responsibilities

12.1 You must provide safe and clear access to the property, roof and solar system, including:

• Unlocked gates and clear paths to the work area and roof access points

• Pets secured away from the work area

• Access to a working outdoor tap and water supply, unless we have agreed otherwise

• Access to the inverter and any monitoring app details needed for a health check, where applicable

12.2 You must tell us before work begins about any known hazards or defects, including fragile or brittle roof tiles, brittle flashings, skylights, steep pitches, asbestos-containing materials, roof leaks, damaged gutters, electrical faults, known solar system faults, or any past problems with your system.

13. Cancellation & No-Access Fees

13.1 Cancellations made with less than 24 hours’ notice may incur a cancellation fee of 25% of the quoted price.

13.2 If we arrive and cannot start or finish the work because of locked access, no water supply, unsafe roof or site conditions you did not tell us about, or other circumstances within your control, a $60 call-out fee may be charged.

14. Safety & Compliance

14.1 All work is carried out in line with Queensland Work Health and Safety laws, our Safe Work Method Statements (SWMS) and site-specific risk assessments. We use appropriate PPE, fall-arrest equipment and roof safety systems.

14.2 We may postpone or stop work at any time if we consider conditions unsafe, including unstable or brittle roofing, excessive pitch, weather, electrical hazards, or hazardous materials such as suspected asbestos. Where work is stopped because of a hazard you did not tell us about, fees under clause 13.2 may apply.

15. Solar Panel Coatings

15.1 Many solar panels have anti-reflective, hydrophobic, nano or clear protective coatings applied by the manufacturer. These coatings naturally degrade over time from UV exposure, heat and weathering.

15.2 We use non-abrasive, solar-specific cleaning tools and purified water systems. However, where a coating has aged, softened, become brittle or failed, minor surface marks, micro-scratches or visible changes in the coating may appear during normal cleaning.

15.3 SunWise is not liable for deterioration, scratching or visible wear to panel coatings caused by pre-existing age, weathering, manufacturer defects or coating failure. Visible changes in an aged coating after cleaning result from its existing condition, not from negligence or misuse.

16. System Performance

16.1 Dirt, dust, bird droppings and grime can reduce the amount of sunlight reaching your panels, and cleaning can remove build-up that may be holding your system back. However, we do not guarantee any specific increase in power output, generation or savings.

16.2 System performance depends on many factors outside our control, including panel age and condition, orientation, tilt, shading, weather, inverter condition, wiring and installation design. Cleaning is not a repair or electrical maintenance activity.

17. Pre-existing Conditions

17.1 We take care to protect your property. However, we are not responsible for loss or damage caused by pre-existing conditions, hidden defects, poor installation, unsafe roof design, structural weakness, or hazards that were not disclosed to us, except to the extent the loss or damage is caused by our negligence.

17.2 Where we notice existing damage or defects, we may photograph and record them before starting work.

18. Photos & Marketing

18.1 We take before-and-after, defect and inverter photos for quality assurance, reporting and record-keeping.

18.2 We may use non-identifiable photos and videos of our work (not showing your address, name, or people) in our marketing. If you do not want your job used in marketing, tell us in writing before the service.

19. Satisfaction, Damage Reporting & Your Consumer Rights

19.1 If you are not satisfied with the cleaning result, please contact us within 48 hours of completion, with photos where possible. Weather, birds and environmental conditions can re-soil surfaces quickly, so prompt reporting lets us fairly assess the result. If the concern relates to our workmanship, we will return and re-clean the affected area at no charge.

19.2 If you believe we have caused damage to your property, please notify us as soon as possible, and within 48 hours where practical, with photos and a description, so we can inspect it.

19.3 Clauses 19.1 and 19.2 set out how to raise a concern quickly. They do not limit your rights under the Australian Consumer Law.

20. Australian Consumer Law

20.1 Our services come with guarantees that cannot be excluded under the Australian Consumer Law, including that services will be provided with due care and skill. Nothing in these Terms & Conditions excludes, restricts or modifies any right or remedy you have under the Australian Consumer Law or any other law that cannot lawfully be excluded.

20.2 Every limitation or exclusion of liability in these terms applies only to the extent permitted by law.

• We are not liable for indirect or consequential loss, including loss of solar generation, feed-in credits, income or profit

• We are not liable for loss or damage to the extent it is caused by pre-existing conditions, your failure to disclose known hazards or defects, work carried out by third parties, or events outside our reasonable control

21.3 You agree to be responsible for loss or damage we suffer, including injury to our workers or damage to our equipment, to the extent it is caused by your failure to disclose a hazard or defect you knew about, or by your breach of these terms.

22. Commercial Clients

22.1 For commercial, industrial, school, government and body-corporate sites, we will comply with reasonable site requirements, including inductions, permits to work, sign-in procedures and site-specific safety documentation. Time spent on inductions, safety documentation or site requirements beyond those in our quote may be charged.

22.2 Variations to the agreed scope, such as additional panels, areas, visits or site requirements, will be quoted and agreed in writing before the work is carried out.

22.3 Where a commercial client’s own terms of engagement or purchase order apply, the parties will agree in writing which terms take priority.

23. Privacy

We collect your name, contact details, property address and job information to quote, schedule, carry out and invoice our services. We will not sell your information, and will only share it where needed to provide our services or where required by law.

24. Governing Law
