Thinking of going solar? It’s a smart move in WA, especially with our long sunny days and rising energy bills. But while most people focus on which panels or inverter to buy, it’s the quality of the installation that really determines how well your system performs.

In WA’s harsh conditions, cutting corners on a solar install can cost you big time. Dodgy wiring or poor system design can drag down the performance of your solar setup. An ill-suited system layout might even shorten its lifespan. These issues often lead to costly repairs, inefficient energy savings and early system failure.

So let’s take a look on the roof and unpack why quality matters, and what to look out for when choosing a solar install in Perth.

Not all solar installs are created equal

A solar system is only as good as the team who designs and installs it. You can buy the most premium panels or inverters on the market, but if they’re installed with poor cabling, no airflow underneath, no thought to best orientation or the best mixes of orientation, no thought to shade patterns or have mismatched inverter configuration? You’re not going to get the output or efficiency you’re paying for. Here’s what a quality solar installation includes:

• System design tailored to your roof and usage: Every home is different – pitch, orientation, shading, household usage. A cookie-cutter install just won’t cut it.
• Correct inverter pairing and placement: The inverter is the heart of your system. A poor match here can reduce overall performance.
• Clean, professional wiring and mounting: Loose wiring or poorly secured panels can create fire risks, reduce lifespan, and cause efficiency drops. We’ve seen installs around Perth’s coast where salt exposure made it even worse.
• Compliance with current Australian Standards: Installers should meet all safety and quality standards to ensure long-term system health. Look for up-to-date knowledge of AS/NZS standards.

The most common solar install pitfalls in Perth

Whether it’s a cheap quote or a rushed job, here are the top mistakes homeowners fall into:

• Going for the cheapest installer: Low-cost installs may skip important steps or use low-grade materials. Over time, this can lead to faults, damage or total system failure.
• Poor panel placement: Incorrect orientation or poor angle setup can reduce the system’s energy yield. It’s critical to factor in WA’s sun path, surrounding shade, and roof angle.
• No after-sales support: If a problem arises post-installation, many customers find themselves without recourse. Choosing an installer with a track record and permanent local presence makes a difference.
• Incomplete or misleading quotes: Some installers underquote, leaving out vital elements like inverters, racking, or monitoring. Always check for a comprehensive quote with no hidden extras.

Key takeaways for Perth homeowners

• A quality solar install is about more than the panels, it’s about the whole system working together efficiently.
• Choosing a provider who understands local conditions, roofing materials, and building standards is key.
• Long-term value comes from durable products, expert installation, and clear, reliable service.
• Look for accredited installers and references from other WA home builders and home owners.
