Solar panels have no moving parts and need very little upkeep, but very little isn't none. At Entire Trades, our licensed electricians look after solar systems across Maitland, the Hunter Valley and the Central Coast, and the systems that keep producing well are the ones that get checked. Solar panel maintenance comes down to three things: keeping the panels clear, watching your system's output, and having a licensed electrician test the electrical side from time to time. Here's what homeowners need to know.

Key Takeaways

• Regular checks help your solar system keep producing at its best and pick up faults before they cost you.
• Dust, bird droppings, leaves and overhanging trees can leave panels dirty or shaded and cut output. Rain doesn't always wash it off.
• You can safely do visual checks and light cleaning from the ground. Electrical testing, inverter faults and roof work are jobs for licensed professionals.
• Entire Trades provides performance monitoring, inverter repairs and replacements, panel replacements and system upgrades. We don't offer panel washing.

How Regular Maintenance Keeps Your System Producing Power

Regular maintenance keeps a solar system safe and producing the power you paid for. Panels on roofs around Maitland, Newcastle and the Hunter Valley sit out in harsh sun, wind and summer storms year after year, and it's a bit like servicing a car.

• Dirty panels, loose connections or an ageing inverter can quietly cut how much power your system makes, with nothing obvious to see from the street.
• Periodic checks help keep the system safe and picking up problems early avoids bigger repair bills.
• A simple maintenance routine covers visual checks, light cleaning where it's safe, keeping an eye on the inverter, and electrical testing by a licensed electrician.

Entire Trades is a family-owned, Maitland-based business that has been serving the Hunter Valley and Central Coast since 2017, and all of our solar electrical work is done by licensed electricians.

Solar Panel Cleaning: Dealing With Dirty Panels Safely

Dirty panels produce less power because grime blocks sunlight from reaching the cells. In the Hunter Valley that grime can be dust off dry paddocks, road film, ash from burn-offs, bird droppings and leaves.

• For panels you can reach safely from the ground, a gentle rinse with a garden hose or a soft brush on an extension pole is usually enough.
• Avoid pressure washers, abrasive tools and harsh chemicals, which can damage the glass and seals.
• Rain helps, but it often won't shift bird droppings or baked-on dirt, especially on low-pitched roofs.
• Never climb on the roof to clean panels. If yours are high or hard to reach, use a properly insured cleaning contractor with roof safety gear. Entire Trades doesn't offer a panel cleaning service.
• A cleaning visit is a good time to book an electrical check so the wiring, isolators and inverter get looked at too.

Checking Panels, Roof Hardware and Nearby Trees

You can check a lot about your solar panels from the ground. This is about spotting obvious problems, not electrical work.

• Panels: Look for cracked glass, burn marks, discolouration, damaged frames or clamps that look loose.
• Mounting hardware: After big winds or hail, look for rails or brackets that have shifted or rusted, without going up on the roof.
• Trees and shade: Trees grow, and a branch that was clear when the system went in may now shade part of the array. Shade moves through the day and the seasons, so a roof that's clear in summer may be shaded in winter. Overhanging trees also drop leaves, twigs and sap onto the panels.
• Trimming: Have a qualified arborist trim branches that shade the panels, especially on the north side of the roof.

Suspected damage, leaks around roof penetrations or loose rails need a licensed electrician or roofer, not a DIY fix.

Looking After Your Solar Inverter and System Performance

The solar inverter turns the DC power from your panels into AC power for your home and the grid, and it's usually where problems show up first.

• On a sunny day, a healthy inverter has its display or status light on, shows no fault lights, and may have a quiet fan running.
• Check the inverter display or monitoring app regularly. Note your daily output and compare it with the same time last year. A sudden drop that weather doesn't explain is worth investigating.
• Warning signs include red or flashing lights and fault messages such as "isolation fault", "grid fault" or "no DC". Most inverters shut down safely when they detect a problem.
• Keep the area around the inverter clear and its vents free of dust and cobwebs, but leave any internal work or testing to a licensed electrician.

When older or faulty hardware starts holding your system back, our solar Maitland services include performance monitoring, inverter repairs and replacements, and panel replacements.

When and How to Schedule Professional Maintenance

Book a licensed electrician to check your solar system periodically, following your installer's and manufacturer's recommendations, and sooner if you see fault codes, a big drop in output or damage after a storm.

• A proper professional check covers the DC and AC wiring, isolators, cabling and earthing, and confirms the inverter is operating correctly.
• Keep a simple log of service dates, fault codes and any changes to the system. It helps the electrician get to the cause faster.
• Entire Trades can check systems installed by other companies and give you a free, written, itemised quote for any repairs or upgrades.
• Professional checks matter most for older systems, and for systems that have been through severe weather, roof work or renovations.
• Never open the inverter or rooftop isolators yourself. If there's a burning smell, arcing or visible damage, follow the shutdown procedure on your inverter label and call a licensed electrician.

Solar is one part of your home's electrical system. Our article on the benefits of regular electrical maintenance for homes covers the rest.

Upgrades, Troubleshooting and How Entire Trades Can Help

As households add air conditioning, batteries, EV chargers and new appliances, the original panels and inverter may no longer suit how much power the home uses.

• Monitoring and performance checks show when an older inverter is limiting output, or when the system is no longer a good match for your usage.
• Before you call, check the switchboard for tripped breakers, confirm the solar main switch is on, and write down or photograph any fault message. It helps us fix the problem faster.
• We can test the system, find faults, replace underperforming panels and upgrade inverters to suit what you need now and later.

Frequently Asked Questions

How often should I have my solar system checked by an electrician?

Follow the maintenance schedule from your installer and the equipment manufacturer, and book a check sooner if you notice fault lights, a sudden drop in generation, or damage after storms or hail.

Can I safely clean solar panels myself?

You can usually rinse panels you can reach safely from the ground with a garden hose, or use a soft brush on an extension pole. Avoid pressure washers, harsh chemicals and climbing on the roof. For high or hard-to-reach panels, use an insured professional cleaner with roof safety gear.

What should I do if my solar inverter shows a fault code?

Write down the exact message or take a photo of the screen, then check your switchboard for tripped breakers. If the fault doesn't clear or keeps coming back, call a licensed electrician.

Do I need to turn my solar system off in storms or heatwaves?

Most modern systems are designed to keep running through normal summer heat and storms. Follow the shutdown procedure on your inverter label if there's roof damage, flooding, a burning smell or emergency work on the wiring.

Can Entire Trades help if another company installed my solar panels?

Yes. Entire Trades can check and repair systems installed by other companies, with written, itemised quotes for inverter repairs and replacements, panel replacements and system upgrades for homes and businesses across Maitland and the Hunter Valley.
