Solar Panel Cleaning in Shropshire
Why Solar Panels Need Cleaning in Shropshire
Panels are self-cleaning in theory: rain runs off the smooth glass and takes the dust with it. In practice that only works on a steep pitch in an open spot. Most Shropshire installations are on domestic roofs at 30–35 degrees, surrounded by trees, farmland or a main road, and the rain never quite clears the bottom edge of each panel.
What builds up there is a band of silt, pollen and moss run-off along the lower frame. Because the cells in a panel are wired in series, a shaded or dirty strip across the bottom drags down the output of the whole panel — not just the part that is covered. That is why a light, even film matters less than a narrow dirty edge.
What It Actually Costs You
Independent testing generally puts losses from soiling in the UK at a few per cent on a clean-ish array, rising well into double figures where there is heavy bird fouling, lichen at the panel edge or farm dust. We are not going to quote you a guaranteed percentage — it depends entirely on how dirty your array is and where it sits. What we will do is show you the panels before and after so you can watch the generation figures yourself.
The properties that gain most around here are the ones under trees in Condover and Church Stretton, anything near working farmland at Baschurch, Ford or Bomere Heath, and roofs beside the A5 and A49 where traffic film settles.
How We Clean Them
The same pure-water system we use on your windows, with a softer head. Tap water is filtered through resin until every dissolved mineral is gone, then fed up a carbon-fibre pole to a brush at panel level. The brush lifts the dirt, the pure water rinses it off, and because there is nothing dissolved in the water it dries without leaving a single spot or smear.
No detergent, no jet washing, no scrapers, and no bleach. High pressure can force water past the panel seals and abrasive pads take the shine off the coating — both are a fast route to an argument with your installer about the warranty.
What we never do
- Walk on the array or lean a ladder against the panel frames
- Use washing-up liquid, bleach or any chemical cleaner
- Pressure-wash panels or their seals
- Clean in bright midday sun, when water dries on the glass before it is rinsed
How Often?
Once a year suits most domestic arrays in Shropshire. Twice a year is worth it if you are under trees, near livestock or arable land, or if you have had a problem with gulls or pigeons. Commercial roofs and ground-mounted arrays usually want a set schedule — tell us the site and we will suggest an interval rather than sell you the maximum.
Most customers have the panels done at the same visit as the gutters, since a blocked gutter under an array is what puts the dirty run-off back across the bottom row in the first place.
Our Solar Panel Cleaning Process
Check
We look at the array, the pitch and the access, and give you a fixed price before we start.
Set Up
The pole and hose are run from the ground, clear of your borders, beds and any cabling.
Clean
Soft brush and deionised water across every panel face, plus the frames and lower edges.
Rinse
A final pure-water rinse, then a walk-round with you so you can see the difference.
Solar Panel Cleaning — Frequently Asked Questions
Will cleaning damage my panels or void the warranty?
No. We use deionised water and a soft brush — no chemicals, no pressure washing and nothing abrasive. That is the method panel manufacturers themselves recommend. What does cause problems is jet washing, bleach and people walking on the array.
Do you need to get on the roof?
No. The whole job is done from the ground with a water-fed pole, which is safer for us and means nothing is standing on your panels or roof tiles.
How much does it cost?
It depends on the number of panels and how easy they are to reach. A typical domestic array on a two-storey house is a straightforward job and we will price it before we start. Doing it alongside a window or gutter visit works out cheaper than a separate call-out.
Will it definitely increase my generation?
If the panels are genuinely dirty, cleaning them will help — particularly if there is a dirty band along the bottom edge. We will not put a percentage on it beforehand, because anyone who does is guessing. Check your inverter readings before and after.
How often should they be done?
Once a year for most Shropshire homes. Twice if you are under trees, near farmland or have gulls and pigeons on the roof.
Do you clean commercial and ground-mounted arrays?
Yes — farm buildings, industrial roofs and ground-mounted systems across Shropshire. Larger sites are quoted per visit with a set schedule.
