Working at Height Rules for Solar Panel Cleaning
Solar panels are designed to provide decades of reliable, renewable energy, but like any external surface, they require periodic maintenance to perform at their best. One aspect of professional solar panel cleaning that homeowners and businesses rarely consider is the legislation and safety procedures involved in working at height.
Whether a property has panels on a bungalow, a two-storey home, an office building or a warehouse, cleaning them safely requires careful planning, the correct equipment and trained professionals. Simply climbing onto a roof with a brush and hosepipe is not only ineffective but can also present serious safety risks.
At Solar Cleaning South West, every project is approached with safety as the priority. Professional working at height procedures help protect technicians, your property and your solar panel system while ensuring the cleaning is carried out efficiently.
What Is Considered Working at Height?
In the UK, working at height refers to any work where a person could fall and suffer injury if suitable precautions are not in place.
This includes:
- Working on rooftops
- Using ladders
- Operating cherry pickers
- Working from scaffolding
- Using Mobile Elevating Work Platforms (MEWPs)
- Accessing elevated platforms
For solar panel cleaning, many installations fall within these categories, particularly on properties with pitched roofs.
Why Working at Height Rules Matter
Falls from height remain one of the leading causes of serious workplace injuries.
Solar panel cleaning involves unique challenges because technicians often work around:
- Fragile roof tiles
- Sloping surfaces
- Electrical equipment
- Changing weather conditions
- Restricted access areas
Professional contractors minimise these risks by following established working procedures rather than taking shortcuts.
Common Types of Solar Panel Installations
Different installations require different access methods.
| Installation Type | Typical Access Method |
|---|---|
| Ground-mounted solar array | Ground access |
| Bungalow roof | Water-fed pole system |
| Two-storey home | Long-reach poles or MEWP |
| Commercial warehouse | Cherry picker |
| School buildings | Powered access equipment |
| Apartment blocks | Boom lift |
The safest method depends on the property rather than applying the same approach to every job.
The Importance of Planning Before Cleaning Begins
Professional solar panel cleaning starts long before any equipment is unloaded.
Every property should be assessed for:
- Roof height
- Roof pitch
- Panel layout
- Ground conditions
- Nearby obstacles
- Vehicle access
- Public safety
- Weather conditions
This planning allows the safest working method to be selected before work begins.
Risk Assessments
A professional contractor should complete a suitable risk assessment before starting work.
This helps identify hazards and determine appropriate control measures.
Typical hazards include:
| Hazard | Control Measure |
|---|---|
| Uneven ground | Stable equipment positioning |
| Slippery surfaces | Appropriate footwear |
| High winds | Delay work if necessary |
| Falling objects | Exclusion zones |
| Public access | Barriers and signage |
| Overhead cables | Safe working distances |
Good planning significantly reduces unnecessary risks.
Choosing the Correct Access Equipment
No single access method suits every property.
Professional companies choose equipment based on safety rather than convenience.
Common options include:
| Equipment | Best Used For |
|---|---|
| Water-fed pole | Low and medium-height panels |
| Ladder | Short-duration access where appropriate |
| Cherry picker | Larger domestic and commercial buildings |
| Boom lift | Difficult-to-reach elevations |
| Scissor lift | Flat commercial buildings |
Selecting the correct equipment helps improve both safety and efficiency.
Why Roof Walking Should Be Avoided
Many homeowners assume technicians simply climb onto the roof.
In reality, this should be avoided wherever possible.
Walking on roofs can:
- Crack tiles
- Damage slates
- Dislodge ridge tiles
- Disturb flashing
- Damage panel fixings
- Increase the risk of falls
Modern cleaning equipment often allows technicians to work safely without standing directly on the roof.
The Role of Water-Fed Pole Systems
Many residential solar panels can be cleaned entirely from ground level.
Purified water-fed pole systems provide several advantages:
- No need to access the roof
- Reduced risk of falls
- Spot-free finish
- No harsh chemicals
- Safe for solar panels
- Faster setup
Ground-based cleaning is often the preferred solution where practical.
Weather Conditions Can Affect Safety
Professional contractors constantly monitor weather forecasts before carrying out work at height.
Poor conditions can quickly make otherwise straightforward jobs unsafe.
| Weather | Impact |
|---|---|
| Heavy rain | Slippery surfaces |
| Strong winds | Unsafe for elevated platforms |
| Ice | Increased fall risk |
| Thunderstorms | Immediate suspension of work |
| Extreme heat | Greater operator fatigue |
Safety should always take priority over maintaining appointment schedules.
