Ireland's domestic and commercial solar PV market is the fastest-growing roof trade. SEAI grants drove a 4x increase in installations between 2021 and 2025, and the HSA has issued multiple campaigns aimed at the resulting wave of fall incidents. If your business installs solar PV in Ireland, here is the safety frame the regulator and your insurer expect.
Why solar is high-risk
- Pitched tile or slate roofs at 30-45 degrees
- Smooth, glass-finished panels turn a "walkable" roof slippery once panels are placed
- Heavy components (15-25kg per panel) being moved at height
- New tradespeople entering the trade fast (electricians, roofers, plumbers crossing trades)
- Tight timelines (SEAI deadlines, customer pressure)
The non-negotiables
- Independent scaffold to eaves on every domestic install. No exceptions, no "we will be quick".
- Roof anchor pre-installed before panels are placed
- Harness in restraint configuration while working on the slope
- Crash deck over fragile materials (rooflights, dormer windows)
- Working at Heights Certificate for every installer on the roof
- Panel hoist or rope hoist - panels are NOT carried up roof ladders
- Daily toolbox talk with weather check
The scaffold question
Some smaller Irish solar contractors try to skip the scaffold for cost reasons. The HSA has been issuing Improvement Notices and Prohibition Notices on this point throughout 2025-2026. Insurance is also tightening: most Irish public liability insurers now require independent scaffolding for any solar PV install over 4m eaves height.
Roof anchor selection
For tile and slate roofs, the realistic options are:
- Permanent eyebolt anchor through the structure into a rafter - left in place after the install for future maintenance
- Type E deadweight anchor on flat roofs only - heavy enough that a fall does not move it
- Temporary anchor strap wrapped over the ridge to a chimney or structural element - check load path
Tying onto a Velux frame, a slate batten or a vent pipe is not an anchor. EN 795 marking required.
Panel handling
A 60-cell PV panel weighs 18-22 kg. Two-person lifts on flat ground; never one-person carry up a roof ladder. Use:
- Panel hoist (mechanical or electric, mounted on the scaffold)
- Rope-and-pulley with safety stop
- Telehandler with man-cage attachment for commercial installs
The fragile materials problem
Modern Irish roofs frequently contain:
- Velux skylights (fragile)
- Polycarbonate dormer cheeks (fragile)
- Older corrugated fibre-cement sheds attached to houses (fragile + asbestos risk)
- GRP roof lights on extensions (fragile)
Survey before quoting. Mark fragile zones with tape on the day of install. Crash deck below.
SEAI grants and safety paperwork
SEAI grant applications now request safety documentation. Customer audits by SEAI have started checking installer credentials. Holding a Working at Heights Certificate for every roof-going installer is a baseline.

FAQs
Does an electrician working only inside a domestic loft need WAH training?
If they cross into the loft from a roof opening or use a stepladder near an unprotected edge, yes. Most Irish solar electricians cover both worlds.
Are micro-generation roofs (under 4kW) exempt from scaffolding?
No. Scaffold is determined by eaves height and pitch, not by panel count.
Can a customer demand we skip the scaffold to lower the quote?
The customer cannot override the SHWW Act. Walk away from the job rather than skip safety.
