Solar Panel Cleaningin Didcot
Didcot has grown in stages, from the old village to Ladygrove and Great Western Park, so its solar arrays sit on every kind of roof. We plan each clean around the installation, then wash the glass with pure water and a soft brush.
- Split and multiple arrays
- Garages and extensions too
- Pure water, no chemicals
How we see it
Count the panels, then look at the house because both shape the clean
Two arrays with the same number of panels can be completely different jobs. One faces an open drive on a simple roof; the other is split between a main slope and a garage, with a conservatory underneath. We look at the whole installation and the ground around it at a free site visit, and plan the clean from there.
Didcot homes
A town built in stages, with roofs to match
Didcot has grown through several distinct periods. Older homes remain around the original village and Northbourne, post-war estates followed, and later came Ladygrove and, more recently, Great Western Park. The result is a wider mix of property types than many of the villages nearby, from period brick to modern render and concrete tile.
Solar panels appear across all of them, fitted when a house was built or added later on a main roof, a rear slope, an extension or a garage. Newer homes often have open fronts and straightforward access; older ones may have narrow side passages and later additions. Open land on the edge of town adds wind-blown dust, while gardens and trees bring pollen and bird mess.
Split installations
One home, two arrays: assessing each section
Some houses have panels on more than one roof slope, or on the main house and a later extension. Those sections belong to one system but rarely age the same way. An upper array in open sky may stay fairly clear while a lower group beside a tree or a neighbouring wall gathers far more debris.
Access can differ too. The upper roof might be within easy reach from the drive while the lower panels sit above a conservatory or behind a fence. We look at every section in turn, so the plan covers the whole installation rather than assuming all the panels are alike.
The bottom edge
Why dirt lines up along the lower frame
Every shower runs down the face of a panel and carries fine dust with it. On a steep roof most of that goes over the edge. On a shallower pitch the water slows, and as it dries against the lower frame it leaves its load behind, building up a dark line that can grow while the middle of the glass looks reasonably clean.
Moss fragments from the tiles above can lodge in the same place. We clear the bottom edge and corners with the soft brush and pure water as part of every clean, using nothing abrasive near the seals.
Even dust
The dull film that is hard to spot from below
Not every dirty array has obvious marks. Fine dust from open ground and building work nearby can settle evenly over the glass, mix with pollen or dew, and leave the whole array slightly dull. From the pavement it simply looks like a solar panel.
A de-ionised water wash lifts that film and rinses it off, and because the water carries no minerals the glass dries clear without being wiped. The aim is plain, clean glass, with no coating or polish left on the surface.
Our process
How a Didcot array is cleaned
Every installation is seen at a free site visit first. On the day, the clean follows the same five stages, section by section.
- 01
Review every section
We note each group of panels, its height, pitch and the ground beneath, plus obstacles such as garages, extensions and conservatories, before choosing where to work from.
- 02
Check the condition
The visible state of the glass, frames and edges is looked over, so anything that looks damaged is raised with you before any water is used.
- 03
Wash with pure water
A soft-bristle brush on a water-fed pole, supplied with de-ionised water, loosens dust, pollen, bird deposits and organic residue without detergents.
- 04
Detail the edges
The lower frames and corners are cleared of grit and moss, then the array gets its final rinse and is left to dry naturally.
- 05
Handover
From a safe position we review the cleaned array with you and explain anything we noticed that sits outside the cleaning, such as a loose fixing.
What it covers
Cleaning the glass, not testing the system
Our work covers the outer surface of the panels and their accessible frames. Generation depends on orientation, roof angle, season, shading and the equipment as much as on clean glass, so we never put a number on the improvement.
- No electrical testing, inverter checks or fault finding
- No repairs to panels, seals, fixings or the roof beneath
- Dust, pollen and droppings return, so cleaning is periodic

Questions
Solar Panel Cleaning in Didcot: your questions
Can you clean panels on a new-build home?
Yes. Panels fitted when the house was built are cleaned in exactly the same way as those added later: de-ionised water, a soft brush on a water-fed pole and no chemicals. Newer homes often have straightforward access, which keeps the work simple.
We have panels on two roof slopes. Do you clean both?
Yes, where both can be reached safely. Each section is assessed on its own at the site visit, because height, angle and the ground beneath can differ, and the quotation covers the whole installation.
Can you reach panels on a garage or single-storey extension?
Usually, yes. Lower roofs are often easy to reach with the pole, though a conservatory, fence or narrow passage alongside can complicate things. We confirm the approach before you book.
Why is there a dirty strip along the bottom of my panels?
Rain carries fine dust down the glass, and on a shallower pitch it dries against the lower frame and leaves the dirt there. Moss fragments from the roof can lodge in the same place. We clear that edge on every clean.
Do you check the inverter or wiring?
No. Our service is cleaning only. If you are worried about how the system is performing, or we notice visible damage, a qualified solar installer is the right person to inspect it.
Is there any chemical in the water?
No. De-ionised water is ordinary water with its dissolved minerals removed. Nothing is added, so no residue is left on the glass and nothing harmful runs into your gutters or garden.
How often should panels be cleaned?
Once a year is a good starting point for many homes. Panels near trees, open fields or regular bird perches, or set at a shallow angle, may need cleaning twice a year. The state of the glass is the best guide.
