Top 10 Common Solar Installation Mistakes to Avoid in South Australia

Installing solar panels is one of the smartest ways to reduce your power bills and take control of your energy costs. But with so many companies and options out there, it’s easy for homeowners to make avoidable mistakes that cost them time, money, and long-term value.

Here are the top 10 common solar installation mistakes South Australian homeowners should avoid ensuring your system performs safely and efficiently for years to come.

1. Choosing the Cheapest Quote Without Checking Quality

It’s tempting to go with the lowest quote, especially when comparing multiple installers. But cheaper isn’t always better. Some companies cut costs by using:

      1. Low-quality panels or inverters

      2. Unaccredited subcontractors

      3. Minimal after-sales support

Tip: Always check what brands they’re installing, warranty terms, and whether they use Solar Accreditation Australia (SAA) accredited installers.

2. Installing Panels in the Wrong Direction

Many homeowners don’t realise how important panel orientation and tilt angle are for solar performance. In South Australia, north-facing panels provide maximum overall output, while west-facing panels are great for evening energy use.

Tip: Ask your installer for a design that suits your household’s energy consumption times for maximum savings.

3. Underestimating Future Energy Needs

Choosing a small solar system might save you upfront, but can limit your future benefits, especially if you:

     1. Buy an electric vehicle

     2. Add battery storage later

     3. Install a pool or expand your home

Tip: Future-proof your system by discussing long-term plans with your installer. Slightly oversizing today can save thousands down the track.

4. Ignoring Shading Issues

Even small areas of shade from trees, antennas, or neighboring buildings can reduce your solar system’s performance significantly.

Tip: A good installer will conduct a full shading analysis to position your panels for maximum sunlight exposure throughout the year.

5. Not Checking Installer Accreditation

Using unaccredited installers can void your eligibility for government rebates and warranties.

Tip: Always check that your installer is a SAA-accredited and NETCC solar retailer and that the individual electricians are SAA-accredited as well.

6. Poor Quality Inverter Choice

The inverter is the “heart” of your solar system, converting DC to usable AC electricity. Choosing a low-quality inverter can lead to:

      1. Frequent breakdowns

      2. Reduced efficiency

      3 Shorter system lifespan

Tip: Invest in a reliable inverter brand with strong Australian warranty support, such as Sungrow, Fronius, or SMA.

7. Overlooking Battery Compatibility

If you’re planning to install a battery in the future, make sure your solar system is battery ready. Retrofitting a battery to an incompatible system can be expensive.

Tip: Discuss battery compatibility and upgrade options with your installer before you commit to your system design.

8. Not Understanding Feed-in Tariffs

Feed-in tariffs (FiTs) in South Australia have reduced significantly in recent years. Some homeowners expect old FiT rates, only to be disappointed with their savings.

Tip: Ask your installer for a realistic financial forecast based on current FiT rates and your household’s energy consumption patterns.

9. Skipping Routine Maintenance

While solar systems are low-maintenance, they’re not zero-maintenance. Ignoring cleaning and inspection can lead to:

       1. Reduced panel efficiency due to dust or debris

       2. Potential electrical faults going unnoticed

       3. Shortened system lifespan

Tip: Clean your panels at least once or twice a year and schedule a professional electrical inspection every few years.

10. Not Reading the Fine Print

Many homeowners don’t read their contract carefully. They miss important details about:

       1. Warranties (what’s covered and what’s not)

       2. Installation timeframes

       3. Hidden fees or variations

Tip: Always read your contract thoroughly. Ask for clarification on anything you don’t understand before signing.
