Solar panels require little maintenance, but should still be professionally cleaned once or twice a year. On top of cleaning, it’s best to schedule a yearly inspection to ensure your solar panels are producing an optimal amount of electricity – with average costs ranging from $150 to $300 for your inspection based on the number of panels, with further costs if repairs or replacement parts are needed.

At Formula Sun we understand the importance of keeping household costs down, so read on for your full breakdown of solar panel maintenance costs in Perth, Western Australia

Your solar panels are out of sight, but they shouldn’t be out of mind.

A good solar system is durable and resilient, designed to run smoothly year after year, but regular maintenance is key to catch any small problems before they become big headaches.

An annual maintenance service is recommended to keep your rooftop solar PV system working properly, which will typically cost between $150 and $300 (based on a 5kW system with 16 panels). If your maintenance service finds any major damage or malfunction, repairs will cost extra (scroll down for pricing).

Although you won’t be able to spot damage or signs of deterioration, the simplest way to identify an underperforming solar panel system is decreased output. If your home’s electricity usage has stayed constant but you find yourself buying more energy from the grid, you may have a problem that requires attention from your local Perth solar technician.

Outside of decreased performance, it’s recommended to schedule an annual maintenance inspection to ensure no damage or decreased output as a result of pests, weather, wear and tear or malfunction.

If you’ve been wondering how often to clean and service your solar system, or been looking to compare prices to find the cheapest Perth solar panel maintenance available, read on for answers to your common solar panel questions.

Do solar panels need a lot of maintenance?

Solar panels are a proven investment able to deliver renewable energy for 25 years (or more) while reducing your power bills.

But knowing when to maintain your solar panels is key to extending their lifespan and getting the most bang for your buck. Thankfully, solar panels contain no moving parts so there is little maintenance required compared to, say, an air conditioner which relies on working internal mechanisms.

The amount of maintenance required will depend on:

  • The number of solar panels
  • The brand of your solar panels
  • The conditioner of your solar panels
  • The surrounding environment by your roof

Solar panel maintenance is a preventative measure, not a cure. If your panels reach the stage where wholesale repairs are needed, you’ve missed the boat.

With maintenance you’ll be able to ensure your system is running as designed, there are no factors inhibiting performance, and all components are working properly.

How often should solar panels be inspected?

Rooftop solar PV systems won’t require much attention after installation, happily working to provide clean, renewable energy to your Perth home year after year, so you’ll only need to schedule routine maintenance every couple of years.

The Clean Energy Council (CEC) recommends organising an annual clean to ensure your solar system is running without problems or performance issues, though there are some warning signs to watch out for that may be signs you need to organise a maintenance check outside of your annual routine.

Consider a one-off inspection if you recognise any of the following red flags:

✘ Unexpected changes to your energy bill
✘ Warning or alerts (applicable if you opt for monitoring software)
✘ When moving into a new property with an existing solar system
✘ If surrounding trees drop regular debris
✘ If you’re concerned pests (rats, possums, pigeons) have damaged your solar panels

Is cleaning the same as maintenance?

No, these are two unique services, though they’re often used interchangeably.

Cleaning your solar panels is important to ensure your system is delivering optimal performance. Naturally, sitting on your roof means your solar panels are exposed to the Western Australian elements. Although solar panels are designed to withstand the worst that the Perth climate can throw at them, dirt and debris stick to your solar panels, blocking sunlight and reducing your system’s efficiency.

It’s worth pointing out that rainfall can naturally remove much of this dirt and debris, but as all Perth homeowners know, the endless hot and sunny days are why you love calling the west coast home, so you can’t rely on Mother Nature for a free rinse. Rain also won’t help clean flat solar panels which collect water, which later evaporates, leaving a thin layer of grime.

Cleaning solar panels in Perth typically costs $10 to $20 each to clean. This makes a 2KW system with 10 panels cost roughly $200 to clean.

How much does it cost to maintain solar panels in Perth?

Maintaining solar panels is a more in-depth service than solar panel cleaning.

You can climb on your roof with a bucket of hot soapy water and wash your solar panels like you’re washing the family car, but it takes a solar technician with experience to provide a maintenance service.

It’s true that solar systems don’t have moving parts to wear down over time, but this doesn’t eliminate the risks of breakdown and malfunction. Your Perth solar technicians will be on the lookout for:

  • Cables chewed by animals
  • Water pooling in components
  • Defective components or signs of malfunction
  • Cable deterioration over time
  • Corrosion on frames
  • Installation mistakes

Solar panel maintenance in Perth typically costs $150 to $300 for an annual inspection and routine maintenance service.

Extra solar panel maintenance costs in Perth

Solar panel maintenance costs vary based on the nature of the problem – and if there’s no problem then you’ll be paying for the inspection without any extras to worry about.

However, if your solar panel check-up shows any signs of damage you’ll need to factor in extra costs to get your system back up and running properly.

Below you’ll find some of the most common solar panel problems found during routine maintenance, along with the average cost of repairs in Perth.

Problem Average Cost
Loose Wiring $135
Cracked Solar Panels $200 to $400
Broken Inverter $1,000 to $2,500
Broken Glass $75 to $400
Corrosion $200 to $500

Factors affecting Perth solar panel maintenance costs

Your local Perth solar technicians will quote your repair costs based on a range of contributing factors, which we’ll cover below for you.

Location

Most solar panels on Perth homes can be found on the roof, although ground solar panels are also seen from time to time. The location of your solar panels also refers to the type of home or business you own. If your solar panels are difficult to reach or require additional safety measures, expect to pay more.

Roof Pitch

The steeper your roof, the more challenging solar panel maintenance typically is. Roof pitch will impact the number of technicians on-site and the time it takes to conduct a routine check-up, both of which will lead to higher prices.

Solar Panel Brand

Although most solar panel brands in Western Australia can be serviced using the same tools, certain brands may require unique cleaning and servicing. Check with your local solar technician to understand what brand of solar panel your home or business uses.

Size

Forget what you’ve heard- size does matter. The larger your solar system, the more expensive it will be to service. Typically, a 5kW system with 15 to 20 panels is sufficient to power a Perth household, though the number of panels you need will depend on your budget and electricity usage.

Inverter Type

All solar systems have an inverter used to convert the direct current (DC) power created by your rooftop solar panels into alternating current (AC) power that your Perth home or business uses to keep the lights on, watch Netflix, and enjoy day to day life. If your inverter is damaged or gives out, your replacement costs will vary. For example, a string inverter is typically cheaper to replace than a microinverter.
