If you’ve installed solar (or you’re thinking about it), it’s normal to wonder what happens after the system goes live. Do you need to clean solar panels? Do they require regular servicing? And will Irish weather affect performance?
The good news is that solar panels are very low maintenance, especially compared to many other home upgrades. They have no moving parts, they’re built to withstand Irish conditions, and for most homeowners, the main “maintenance” is simply keeping an eye on system performance through monitoring.
At Activ8 Solar Energies, we’re Ireland's solar experts celebrating our 20th year in business with over 25,000 installations on the island of Ireland, and we’ve installed systems in every type of setting—from coastal homes to rural properties and busy suburban rooftops.
In most cases, solar panels do not need regular hands-on maintenance.
However, like any electrical system, a solar PV setup can benefit from:
Most of the time, your panels will keep generating electricity quietly in the background—without you having to do anything.
Usually, no—and this surprises a lot of homeowners.
Ireland’s frequent rain helps naturally wash away:
That said, there are a few situations where cleaning may help improve performance.
You might consider cleaning if you notice:
A key point: solar panels don’t have to look spotless to work well, but heavy soiling can reduce output.
The best way to know isn’t by guessing—it’s by checking your monitoring app.
If your system is producing noticeably less than expected (and weather conditions are normal), it may be worth checking for:
A simple routine:
If the numbers drop suddenly or stay unusually low, that’s when cleaning or a system check can be worthwhile.
If you do decide to clean your panels, safety comes first.
Avoid:
If your panels are easily reachable (like on a flat roof extension), you can:
For most homes in Ireland, the safest option is a professional clean—only when needed.
Solar panels themselves rarely need servicing, but your solar PV system includes other components that may require attention over time, such as:
So while solar panels don’t need “servicing” like a boiler, it’s smart to treat the full system as something worth checking occasionally.
Here are the most common things homeowners experience:
Often caused by:
Sometimes the system is still generating perfectly, but the app shows no data due to:
Inverters protect your home and the grid. Occasional faults can occur, including:
If you see repeated errors, it’s worth contacting your installer.
A simple maintenance approach is best.
This keeps the system running efficiently without overcomplicating it.
Solar panels are built for harsh outdoor environments, including:
Most panels and mounting systems are designed and tested to withstand tough conditions. The real factor is installation quality—secure mounting, correct waterproofing and safe electrical setup.
If your system includes battery storage, it’s still low maintenance, but there are a few best practices:
Good quality batteries are designed to run automatically with minimal input from the homeowner.
The best maintenance tool isn’t a brush—it’s your monitoring app.
Monitoring helps you:
Many issues are resolved faster when they’re caught early.
You should contact a professional if:
For most homeowners, solar panel maintenance is simple:
And if you want maximum peace of mind, choosing an experienced installer with strong aftercare makes all the difference.

Usually not. Irish rain naturally washes most dirt away. Cleaning is only needed if heavy soiling or bird droppings are reducing performance.
Most homes don’t need cleaning more than once every few years (if at all). Monitoring your output is the best way to decide.
It’s possible if panels are safely reachable, but avoid climbing on roofs. Never use pressure washers or harsh chemicals.
Solar panels don’t need annual servicing like boilers, but occasional professional inspections can help spot issues early.
Checking your monitoring app regularly. It helps you spot changes in performance and alerts you to faults.
Your system may still be generating electricity. Monitoring outages are often caused by WiFi/router changes and can usually be fixed quickly.
