I’ll never forget the panicked phone call I got from my neighbor three winters ago. “My solar panels are covered in snow,” he said, voice trembling like his electricity bill was about to skyrocket. “Should I get up on the roof with a broom?”
My answer? Absolutely not. Put down the broom, step away from the ladder, and let me explain something about solar maintenance that might just save you from a trip to the emergency room.
After spending more than two decades in the energy sector and earning my stripes as a chemical engineer, I’ve heard every solar panel maintenance myth imaginable. Some are harmless misunderstandings. Others are genuinely dangerous. And a surprising number of them lead homeowners to either neglect their systems entirely or obsess over maintenance that isn’t necessary.
The team at Positive Energy Solutions addresses these misconceptions daily. Andy and his team have made it their mission to educate New Jersey homeowners about what solar energy maintenance actually looks like in practice, not in theory, not in internet forums, but in the real world where weather happens, and life gets busy.
Let’s bust some myths and discuss what actually matters when it comes to keeping your solar investment performing at its peak.
The Great Snow Debate: Why Patience Beats Panic
Back to my neighbor on that snowy December morning. His instinct to clear the panels immediately is one I see constantly, and I understand it. You’ve made a significant investment in solar technology, and watching it sit under a blanket of white feels wrong. But here’s the science behind why patience is usually the right approach.
Solar panels are dark-colored and generate heat even in minimal sunlight. They’re also installed at an angle. This combination means snow typically sheds on its own, often within a day or two. More importantly, climbing onto a snow-covered roof is genuinely dangerous, and using tools to scrape panels can cause micro-scratches that accumulate over time and reduce efficiency.
Does a solar panel need maintenance after a snowstorm? In most cases, the maintenance is simply waiting. Your panels will clear themselves, and accelerating that process introduces risk without meaningful benefit. This is one area where doing nothing is actually the right approach to solar system maintenance.
Now, if you have a ground-mounted system or a particularly flat roof where snow accumulates and persists for weeks, that’s a different conversation. But for the typical residential installation in New Jersey, let gravity and thermodynamics do their job.
Seasonal Solar Maintenance: A Year-Round Perspective
One thing I’ve learned from my engineering background is that systems behave differently under different conditions. Your solar panels in July are not the same as in January, at least in terms of what they require from you. Let me walk you through a seasonal approach to solar panel maintenance that makes sense.
Spring: The Deep Clean Season
If there’s one time of year when your panels genuinely benefit from attention, it’s spring. Winter leaves behind a cocktail of grime: salt residue from nearby roads, decomposed leaves that blew in during fall storms, and whatever the local bird population deposited during their winter roosting.
Spring is also pollen season here in New Jersey, and if you’ve ever seen your car turn yellow-green in April, you know what I’m talking about. That same pollen coats your panels and can meaningfully impact performance.
This is when a thorough cleaning makes the most difference. Early in the morning, before the panels heat up, use a soft-bristled brush and plain water to gently remove accumulated debris. If you’re not comfortable on a ladder or your panels are difficult to access, this is an excellent time to call professionals like the team at Positive Energy Solutions for solar panel service and maintenance.
Summer: Monitor and Enjoy
Summer is when your panels work hardest, generating maximum power during long, sunny days. Your primary job during this season? Pay attention to your monitoring system.
Do solar panels require maintenance during peak production months? Mostly, they require observation. Watch your daily and weekly production numbers. Compare them to the same period last year if available. Any significant unexplained drops warrant investigation.
Summer is also when thermal stress is highest. Panels expand and contract with temperature swings, and mounting hardware can gradually loosen. A visual inspection from the ground for any panels that appear out of alignment is worthwhile. But honestly, if your system is properly installed, summer maintenance is largely about appreciation, watching those kilowatt-hours stack up.
Fall: Prepare for What’s Coming
Leaves are the enemy in autumn. A single wet leaf stuck to a panel can create a hot spot that affects efficiency and, in extreme cases, can cause long-term damage. This is where regular visual inspection becomes critical.
How to maintain solar panels during the fall? Monitor leaf accumulation, especially if you have deciduous trees nearby. A quick rinse with a garden hose can prevent small problems from becoming larger ones. Also, check that your gutters are clear; overflow from clogged gutters can splash dirty water onto lower panels.
Fall is also an excellent time for a professional inspection. Before winter weather arrives, having a technician verify that all connections are secure and mounting hardware is tight gives you peace of mind for the challenging months ahead. Andy’s team at Positive Energy Solutions offers comprehensive fall check-ups that I highly recommend.
Winter: The Hands-Off Season
We’ve already covered the snow situation, but winter solar systems maintenance extends beyond precipitation. Shorter days mean less production, which is normal and expected. Don’t panic when your December numbers are a fraction of your July output.
What you should watch for: ice dams on your roof that could affect drainage around your panels, and any unusual accumulation of debris that wind might deposit. Beyond that, winter is about letting your system do its thing while you stay warm inside.
The Cleaning Product Catastrophe
Here’s a myth that makes me cringe every time I hear it: “I use glass cleaner on my windows, so I should use it on my solar panels too.”
Please don’t do this.
Most commercial glass cleaners contain ammonia or other chemicals that can degrade the anti-reflective coating on solar panels. This coating exists for a reason: it maximizes light absorption and therefore energy production. Damaging it in the name of cleanliness is counterproductive.
How should a solar panel be maintained? Water. Just water. Maybe a tiny amount of mild dish soap if you’re dealing with particularly stubborn grime. That’s it. Your panels don’t need special solutions, proprietary cleaning products, or anything else that someone might try to sell you. The simplest approach to solar power servicing is often the best one.
The Myth of Constant Monitoring
I’ve met homeowners who check their solar monitoring app more often than their email. Every cloud that passes overhead triggers anxiety. Every minor fluctuation in production sends them into a spiral.
This is unhealthy and unnecessary.
Do solar panels need to be serviced every time production dips for an afternoon? Of course not. Solar energy maintenance is about trends, not moments. A week of underperformance compared to historical data? Worth investigating. A cloudy Tuesday? That’s just weather.
Check your system weekly or monthly, not hourly. Look for patterns over time. Trust the technology. Modern solar systems are remarkably reliable, and obsessive monitoring doesn’t make them more so.
When Professional Help Actually Matters
Let me be clear: while I’m a strong advocate for homeowner education and basic DIY maintenance, there are situations where professional solar panel maintenance isn’t optional.
Electrical issues require professional attention. Period. If you notice burning smells, see scorch marks anywhere on your system, or your inverter is throwing error codes, call a professional immediately. This isn’t the time for YouTube tutorials or neighborly advice.
Significant physical damage, whether from storms, fallen branches, or other impacts, needs professional assessment. What appears to be a minor crack may have compromised the panel’s weatherproofing in ways that aren’t immediately visible.
And frankly, annual or biennial professional inspections are just good practice. The team at Positive Energy Solutions uses thermal imaging equipment to detect issues invisible to the naked eye. They can measure string-level performance, test electrical connections, and evaluate your system with tools and expertise that homeowners simply don’t have access to.
Think of professional solar panel service and maintenance as an investment in longevity. A few hundred dollars every couple of years can prevent thousands in premature replacements or lost production.
The Efficiency Obsession
Here’s a final myth I want to address: the idea that your panels need to operate at peak manufacturer-rated efficiency at all times, or something is wrong.
Real-world conditions are not laboratory conditions. Temperature affects performance. Angle of sunlight affects performance. Humidity affects performance. A certain degree of efficiency loss relative to rated specifications is normal.
What matters for practical solar maintenance isn’t achieving theoretical maximums. It’s ensuring consistent, predictable performance over time. If your system produced 10,000 kWh last year under certain conditions, it should produce roughly the same under similar conditions this year, accounting for the normal 0.5% annual degradation that all panels experience.
Solar panels upkeep is about maintaining that consistency, not chasing impossible perfection.
The Real Secret to Solar Success
After all these years in the energy industry, and working in different parts of the business from solar installation to dealing with home improvement lead generation companies and solar repair and maintenance companies. After working with many systems and diagnosing problems, I can share the real secret to successful solar maintenance: it’s not complicated, but it does require consistency.
Regular visual inspections. Occasional cleaning when genuinely needed. Monitoring system performance over time. Professional check-ups every year or two. That’s it. That’s the whole formula.
Do solar panels need maintenance? Yes, but less than you probably fear and more than you might hope. The sweet spot is somewhere between neglect and obsession, a middle path where you pay attention without driving yourself crazy.
Positive Energy Solutions has built its business on this philosophy. Andy and his team don’t try to sell you unnecessary maintenance contracts or frighten you with horror stories. They educate, they support, and they’re there when you genuinely need them. That’s the kind of partnership that makes solar ownership sustainable in every sense.
Your panels are up there on your roof right now, quietly converting photons into electrons, physics happening in real-time on your property. They don’t need you to constantly worry about them. They just need you to care enough to pay attention when it matters.
And maybe stay off the roof when it’s snowy. Seriously. Put down the broom.
