Our method

A protocol built to protect your cells

Pressure washers and harsh detergents can permanently damage the anti-reflective coating on solar modules. That's why every job follows the same careful, tested protocol.

💧

Reverse-osmosis pure water

A portable reverse-osmosis filtration rig produces mineral-free water on site: no limescale residue, and panels dry naturally without streaks.

  • Streak-free, natural air-drying
  • No chemical residue left on the glass
  • Safe on every roof and mounting type
🧹

Soft-bristle telescopic tools

We work from ground level up to 15 metres with non-abrasive brush heads — no ladders or scaffolding required for most domestic jobs.

  • Safer for our team and your roof
  • Anti-scratch soft bristles
  • Low pressure, no thermal shock to the glass
📷

Visual inspection & report

Every clean includes a visual check of frames, glass and visible connections, with a photo report emailed to you afterwards.

  • Flags visible hot-spot indicators
  • Checks for organic build-up and staining
  • Report sent within 24 hours

Tell us how many panels you have and we'll give you a fixed price over the phone — no deposit required, no surprises on the day.
