Solar Panel Cleaning Northern Ireland

Dirty solar panels lose up to 25% of their output, silently costing your business every month. WPE's specialist cleaning service restores full performance, protects your warranty, and keeps your investment generating what it should. As electrical contractors, we go further than any cleaning company can.

Why Your Panels Need Professional Cleaning

Rain doesn't clean solar panels, it moves dirt around. Dust, bird droppings, pollen, algae, and pollution accumulate gradually, blocking sunlight from reaching the cells beneath the glass. In Northern Ireland, agricultural premises, coastal sites, and urban rooftops are particularly affected. Studies consistently show contamination can reduce panel output by up to 25%. For a business saving £10,000 per year through solar, that's £2,500 in avoidable losses annually — often recoverable in a single professional clean.

Why tap water and pressure washing make things worse:

• Tap water leaves mineral deposits on the glass, reducing output over time

• Pressure washing cracks cells beneath the glass and voids most panel warranties

• DIY cleaning without deionised water can permanently reduce panel efficiency

• Most panel manufacturers specify deionised water only in their warranty terms
