What cleaning covers
Cleaning deals with what sits on top of the glass: bird mess, dust, pollen, traffic and industrial grime, leaf and sap residue, and organic growth around the frames where it can be reached safely. It is surface work, carried out with purified water and equipment suited to panel glass.
Cleaning removes surface contamination. Whether this produces a noticeable generation difference depends on how dirty the panels were and the wider condition of the system. That is the limit of what a clean can honestly claim.
What system maintenance covers
System maintenance is a different discipline and normally involves electrical work. It can include inverter diagnostics and replacement, checking DC and AC cabling, isolators and switchgear, testing strings and individual modules, inspecting mounting rails and fixings, verifying earthing and protection, and analysing output data over time to find where generation is being lost.
MK Solar Care is a cleaning service. Electrical work, testing and system repairs are not carried out here, and no claim of electrical certification or manufacturer approval is made on this site.

Telling one problem from the other
A useful starting point is to compare what you can see with what the system reports. If the panels are visibly soiled, particularly with concentrated bird mess or heavy organic growth, cleaning is a sensible step. If generation has dropped noticeably while the glass looks reasonably clean, the cause is more likely to sit inside the system.
If the problem appears to involve the inverter, wiring or electrical output rather than surface contamination, the appropriate next step may be a qualified solar technician rather than cleaning. Sudden drops, error codes on the inverter display, a string producing nothing at all, or output that fell overnight rather than gradually all point that way.
Gradual seasonal variation is normal and not in itself a fault. Shorter days, lower sun angles and heavier cloud cover across a British winter reduce generation regardless of how clean the panels are.
What can be observed during a cleaning visit
While cleaning an array, obvious physical issues sometimes become visible: a cracked module, a panel sitting out of line, damaged or sagging cable clips, birds nesting under the array, or vegetation growing into the mounting. Anything of that sort is reported to you plainly so you can decide whether to bring in a solar or electrical specialist.
That is an observation, not an inspection or a test. It carries no certification and does not replace a proper system check by someone qualified to carry one out.
Maintenance-minded care in Milton Keynes
Many Milton Keynes installations date from a period of active solar uptake, and a fair number have simply been left since commissioning. Keeping the glass clear of stubborn contamination, keeping vegetation away from the array and noticing physical damage early are all reasonable parts of looking after a system, and they sit comfortably within a cleaning remit.
If you are unsure which route you need, describe what you have noticed: what the panels look like, what the inverter is showing, and when the change happened. If cleaning is the answer, we will quote for it. If it is not, we will tell you that a qualified solar technician is the better call.
