A Deep Dive on Solar Panel Efficiency in Australia

Solar panels have become an increasingly popular way to generate clean, renewable energy in Australia. As technology has advanced, solar panels have become more efficient, meaning that they are able to generate more electricity from the same amount of sunlight.

How efficient is solar energy?

The average solar panel efficiency is much higher than used to be – but which solar panel manufacturers provide high-efficiency solar panels? What are the most efficient solar panels? What is the best process for solar panel installation?

In this blog post, we will explore the highest efficiency solar panels and the newest solar panels available in 2023 in Australia.

Solar cells are an efficient source of renewable energy, with efficiency depending on factors such as the type of solar panel system technology used, weather conditions, and the location of the panels. Silicon cells are the most common technology and have efficiencies ranging from 15% to 20%, but newer technologies such as perovskite cells are showing greater promise with efficiencies exceeding 25%. One thing’s for sure – there are more efficient solar panels on the way.

Mono-crystalline Solar Panels

Monocrystalline solar panels are made from single silicon crystals, which give them a uniform appearance. These panels are known for their high efficiency and ability to generate more electricity per square metre than other types of solar panels. Mono-crystalline solar panels typically have efficiency ratings of between 18% and 24%. They are also known for their durability, with many manufacturers offering warranties of up to 25 years.

Polycrystalline Solar Panels

Polycrystalline solar panels are made from multiple silicon crystals, which give them a textured appearance. These panels are slightly less efficient than mono-crystalline panels, with efficiency ratings of between 15% and 20%. However, they are generally less expensive than mono-crystalline panels and can be a good option for those on a budget. Polycrystalline panels also have a long lifespan and typically come with warranties of up to 25 years.

Thin-Film Solar Panels

Thin-film solar panels are made by layering thin films of photovoltaic material onto a substrate. These panels are typically less efficient than crystalline silicon panels, with efficiency ratings of between 10% and 13%. However, they are lightweight and flexible, making them a good option for certain applications, such as on curved or uneven surfaces. Thin-film solar panels also tend to perform better in low-light conditions than crystalline silicon panels.

Bifacial Solar Panels

Bifacial solar panels are a relatively new type of solar panel that is designed to absorb sunlight from both sides of the panel. These panels are typically made from crystalline silicon and have efficiency ratings of between 18% and 22%. Bifacial solar panels can be a good option for installations with reflective surfaces, such as snow or water, as they are able to capture light that is reflected onto the back of the panel.

Concentrated Solar Panels

 Concentrated solar panels use mirrors or lenses to focus sunlight onto a small area, which is then used to generate electricity. These panels are typically used in large-scale solar power plants rather than residential or commercial installations. Concentrated solar panels have the highest efficiency ratings of any type of solar panel, with some panels reaching efficiencies of up to 40%.


Solar panels are a great way to generate clean, renewable energy in Australia. As technology has advanced, solar panels have become more efficient, meaning that they are able to generate more electricity from the same amount of sunlight. How efficient is solar energy? The most efficient types of solar panels available in 2023 in Australia include mono-crystalline, polycrystalline, thin-film, bifacial, and concentrated solar panels. When choosing a solar panel, it is important to consider factors such as efficiency, durability, and cost, as well as your specific energy needs and location. By choosing the right solar panel for your circumstances, you can generate clean, renewable energy and save money on your energy bills for years to come.

Frequently Asked Questions

How long do your Sydney solar panels last?

Around 25 years, provided they’re well-maintained. Solar panels need to be regularly cleaned and serviced, whether by yourself or a professional.

What types of houses are compatible with solar panels?

Generally, most homes are compatible with solar panels. Homes with south-facing roofs may not be ideal for solar panels — but there are options, such as ground-mounted panels as alternatives.
