Top 5 Questions to Ask Before Installing Solar Panels

Thinking about installing solar panels on your home or business in Bunbury, Busselton, or the South West? You’re not alone. With WA’s rising energy prices and growing focus on sustainability, solar is one of the smartest investments you can make. But before you dive in, it’s important to ask the right questions to make sure you get the best system for your needs.

Is My Roof Suitable for Solar Panels?

Not every roof is created equal when it comes to solar. Factors like the angle (pitch) of your roof, the direction it faces, and any potential shading from trees or nearby buildings can all affect how much energy your system will produce.

  • Ideally, north-facing roofs in WA get the best sunlight exposure.
  • We recommend a professional on-site assessment to check your roof’s condition, orientation, and sun exposure before you commit.

What Size System Do I Actually Need?

Choosing the right system size is crucial. Too small, and you won’t meet your energy needs. Too big, and you might not get the best return on investment.

  • Start by looking at your past electricity bills to understand your average usage.
  • Consider your future needs too, planning an EV purchase or home extension? You might need a larger system.

How Much Will I Save? And How Long Until It Pays Off?

Solar is an upfront investment, but the savings over time can be massive, especially with WA’s sunny climate.

  • Ask for a clear breakdown of expected savings per year and the estimated payback period.
  • Don’t forget to factor in available rebates and incentives, many South West homeowners are eligible for Federal Small-scale Technology Certificates (STCs), which can significantly reduce installation costs.

What Quality Panels and Inverters Are Being Installed?

Not all solar panels are built to last, and neither are all installers.

  • Always ask about the brands of panels and inverters being recommended. Look for trusted names backed by strong warranties (think 25 years for panels and at least 10 years for inverters).
  • High-quality products perform better, last longer, and are more efficient in the long run, saving you more money over time.

Who Will Install and Maintain the System?

A top-quality solar system deserves a top-quality installation.

  • Make sure your installer is CEC (Clean Energy Council) accredited, it’s a must for accessing government incentives.
  • Find out about after-sales support and maintenance options. Solar systems need occasional servicing to stay in peak condition.
