What if your solar investment doesn't save you as much money as you expected? You could end up paying more than necessary simply because of a few decisions made before installation.

With Perth receiving plenty of sunshine throughout the year, solar energy has become an attractive option for Australian homeowners looking to reduce electricity expenses and make their homes more energy-efficient. But here's something worth considering: buying quality solar panels doesn't automatically guarantee a good solar investment.

From choosing the wrong installer to overlooking roof conditions and missing government incentives, small mistakes can affect your system's performance and long-term value.

If you're planning to install solar panels at your Perth home, take a few minutes to understand these three common mistakes before making your decision.

1. Choosing a Solar Installer Based Only on Price

Who doesn't love saving money? When homeowners compare solar installation quotes, it's natural to be attracted to the cheapest offer. However, choosing a solar company based entirely on price can sometimes lead to bigger expenses later.

Not all solar packages offer the same quality. Two companies might quote similar system sizes, but the products, installation standards, warranties and after-sales services could be very different.

For example, an attractive quote might not include certain electrical work or additional installation requirements. Some homeowners only discover these details after committing to the project.

What should you do instead?

Before selecting a solar installer in Perth:

·       Compare at least two or three detailed installation quotes.

·       Check customer reviews and previous installation experience.

·       Ask about the quality and performance of the proposed solar panels and inverters.

·       Verify relevant installer accreditation and electrical licences.

·       Understand product warranties and workmanship coverage.

·       Confirm exactly what is included in the final price.

Remember, the cheapest system isn't necessarily the most affordable in the long run. Focus on quality, reliability and the overall value you're getting for your money.

2. Overlooking Roof Conditions, Installation Quality and Maintenance

Here's a mistake that can quietly affect your solar savings: assuming every roof is suitable for the same solar panel arrangement.

Perth's sunny weather provides excellent opportunities for solar generation, but your property's roof still plays an important role in system performance.

Roof direction, panel orientation, nearby trees, shading and available space can all influence how much electricity your panels produce.

For instance, installing panels in an area that receives significant shade during important sunlight hours may reduce energy generation. Similarly, an unsuitable system design or poor installation practices could create performance and safety concerns.

And what happens after installation? Some homeowners assume their solar panels will continue working perfectly without any attention.

Although solar systems generally require relatively little maintenance, monitoring their performance is still important.

How can you avoid these problems?

·       Arrange a proper roof assessment before installation.

·       Consider roof orientation and shading throughout the day.

·       Select a system size based on your household's electricity consumption.

·       Make sure the panels and inverter are compatible.

·       Use appropriately accredited professionals and licensed electricians.

·       Monitor your system regularly through its monitoring application.

·       Arrange cleaning and inspections when necessary.

Also, ask your installer about after-sales support. Knowing who to contact if your system develops a problem can save considerable frustration.

3. Missing Government Solar Rebates and Incentives

What if you could reduce your upfront solar installation costs without compromising on system quality?

Many Perth homeowners spend hours comparing solar panel prices but forget to check which government incentives might be available. This can mean missing an opportunity to make their investment more affordable.

Australia's Small-scale Renewable Energy Scheme (SRES) provides financial support for eligible small-scale solar installations through Small-scale Technology Certificates (STCs). These are commonly applied as an upfront discount by the solar retailer or installer.

Homeowners considering battery storage may also be eligible for support through the Australian Government's Cheaper Home Batteries Program and relevant Western Australian residential battery arrangements.

However, not every household or installation automatically qualifies. Eligibility conditions, approved products and incentive values can change.

How can you avoid missing out?

·       Ask your installer whether the quoted price includes the applicable STC discount.

·       Check current federal and Western Australian incentive requirements.

·       Explore battery incentives if you plan to add energy storage.

·       Confirm that your chosen products and installer meet eligibility conditions.

·       Understand how discounts are calculated and applied to your final bill.

Don't rely entirely on advertised rebate amounts. Check the latest government information and make sure you understand the actual savings available to your household.
