Solar energy has gone from sci-fi fantasy to rooftop reality, and it’s no longer just something your particularly smug neighbour boasts about. With rising energy costs and an urgent need to reduce carbon emissions, more property owners are turning to solar panel installations as a long-term solution. But while the panels themselves are low-maintenance by design, they’re not entirely immune to grime, weather tantrums, or the occasional bird deciding to take up residence.
Choosing solar panels and installing them is only the beginning. Knowing how to care for your panels once they’re in place is key to keeping them running efficiently for decades. So before you let the sun do all the work, here’s how to keep those panels squeaky clean and working like the overachievers they were made to be.
What a Good Installer Brings to the Table
The world of solar can be dazzling, quite literally, and choosing a solar panel installer isn’t a task to leave to chance—or to your cousin’s friend who once read a blog about it. Getting it wrong can mean panels that underperform, roof damage, or, worse, a complete redo at double the cost.
A professional installer understands the technical and logistical side of things. They assess how much sunlight your property receives throughout the year, calculate the optimal tilt and orientation, and ensure the wiring meets safety standards. No guesswork, no duct tape. They’ll also explain system capacity in plain terms rather than baffling you with equations that look like they belong in a physics exam.
It’s not all rooftop gymnastics either. A good installer handles permissions and inspections, ensuring your solar setup isn’t just functional, but legally sound. They’ll even guide you through system monitoring so you can check your energy production like a proud plant parent showing off their thriving monstera. With so much riding on this first step, choosing someone qualified, experienced, and responsive isn’t just a good idea—it’s essential.
Cleaning Without Causing Chaos
Solar panels bask in the sun all day, but they don’t exactly get a free exfoliating facial while they’re up there. Over time, dust, leaves, bird droppings, and other questionable residues can block sunlight and reduce efficiency. And if you think a good rainstorm will handle the cleaning, think again—Singapore’s humidity helps the dirt stick like an overzealous sticker on a laptop.

So, how do you clean them without turning your roof into an episode of a slapstick comedy? The answer lies in a gentle touch and the right timing. Early morning or late afternoon is best when the panels are cool to avoid thermal shock (or burning your fingertips). Use a soft cloth, sponge, or a non-abrasive brush paired with plain water. Avoid soap or chemicals as they can leave residue worse than the grime you started with.
In most cases, a few cleanings per year will do the trick—though if your panels sit beneath a tree or beside a construction site, more frequent check-ups won’t hurt. And if climbing ladders isn’t your thing, professional cleaners can handle it. It might not be glamorous, but a clear panel equals a happier, more productive solar system.
Keep an Eye on the Output
Maintenance isn’t just about cleaning. It’s also about keeping tabs on performance to catch any issues early. Most systems come with monitoring apps or devices that display how much energy your panels are producing. If the numbers start to dip unexpectedly—say, there’s no cloud in sight, but your system thinks it’s midnight—it’s time to investigate.

Loose wiring, faulty inverters, or damaged panels can impact output. While the system might still function, it won’t be working at full tilt, which defeats the whole purpose of making the switch in the first place. A professional inspection every year or two can help ensure the system’s components are in good shape and functioning as they should.
And here’s the best part: most well-installed systems come with warranties. That means you’re covered in the event of hardware failures or defects, though it’s worth checking what your warranty does (and doesn’t) include. When in doubt, consult your solar panel installer—they’ll know your setup and how to get it back on track.
Installing solar panels and installation services is a step towards greener energy and lower bills, but the benefits don’t end at installation. Maintaining your panels through cleaning, monitoring, and occasional inspections ensures your system remains as efficient as the day it was fitted. With the right solar panel installer, you won’t just have panels stuck to your roof—you’ll have a long-term, sun-powered investment that keeps giving.
