Solar-panel cleaning and condition inspection — Solar panel installer
Describe the visible soiling and provide safe ground-level photographs and system details. Ask the provider to distinguish what will be cleaned and visually checked from any electrical or roof assessment, particularly if the enquiry follows a drop in output rather than obvious surface contamination.
Service scope
A combined request for appropriate cleaning of PV surfaces and an agreed visual condition review, with safe access and manufacturer-compatible methods established first. Surface cleaning is distinct from electrical testing or full-system maintenance and does not guarantee recovery of a specific amount of generation.
What is normally included
- Cleaning-need and access assessment
- Compatible professional panel cleaning
- Defined visual findings and referral
What is not included
- Automatic electrical certification
- Unverified pressure-washing or abrasive cleaning methods
Typical tasks
- Assess the apparent cleaning need
- Check access and method compatibility
- Clean the agreed surfaces professionally
- Record visible condition concerns
- Refer electrical or roof issues outside the scope
What to include in your brief
- Array location and size
- Visible soiling
- Module or installation information
- Safe access options
- Requested inspection depth
Choosing the right professional
Ask how the cleaning method is checked against the modules and mounting arrangement and what the inspection report actually covers. Do not treat a washing service as evidence that the electrical system is safe or that reduced generation was caused by dirt.
Important considerations
- Unsuitable cleaning can damage modules or their surroundings
- Roof access and nearby electrical equipment require a safe professional approach
