Australia is one of the sunniest places on earth. For instance, Sydney receives around 2,592 peak sun hours per year, averaging between 6 and 8 hours per day. No wonder, the future of clean and green renewable energy is much brighter here.
In recent years, we have embraced solar energy with millions of homes and businesses turning to solar panels to harness the country’s abundant sunshine. Solar panel installation has seen a massive increase in Aussie homes with some suburbs in Sydney having as high as 70% of dwellings with an existing solar installation on the roof while most suburbs across Sydney are above 50%.
The time to make the switch to sun energy has never been better. In this comprehensive guide, we have covered everything you need to know about solar panels.
Benefits of Solar Panel Installation
Reduced Electricity Bills
With solar panels generating electricity from the sun, you’ll significantly cut down on your energy bills. According to the Clean Energy Regulator, a typical 5kW system can save an Australian household up to $1,500 per year on electricity costs.
Energy Independence
Solar power installation allows you to become less reliant on the grid, providing energy security and peace of mind, especially during peak periods or grid outages.
Increase in Property Value
Studies show that homes with solar systems tend to attract higher prices. It’s an attractive feature for environmentally conscious buyers and those looking to save on energy bills.
Low Maintenance Costs
Solar panels require minimal maintenance once installed. Most systems come with warranties that cover performance for up to 25 years.
Government Incentives
Generous government incentives, rebates, and feed-in tariffs make switching to solar an attractive and affordable option for households and businesses.
A part from these benefits, switching to solar helps you contribute to saving the environment.
- A residential solar system can reduce your household’s carbon footprint by around 1.5 to 2.5 tonnes of CO2 per year. This is equivalent to planting 60 to 100 trees annually.

- The federal government’s Small-Scale Renewable Energy Scheme (SRES) provides financial incentives that reduce the upfront cost of solar systems.
Rise in Solar Power Trends
In the recent data, Renewable energy constituted 40% of total energy production in the continent. This is huge for an entire nation to have such a massive shift to sustainable resources.
With more consumption, it has produced more innovation. Here are some popular trends in solar power –
- Over 3.4 million small-scale solar systems have been installed across Australia as of 2024, and this number continues to grow rapidly.
- A sudden rise is seen in homeowners opting for battery storage for their solar systems, aiming for greater energy independence and backup power.
- Community solar projects and solar gardens are on the rise, offering opportunities for renters and those with unsuitable rooftops to participate in solar energy generation.
- Businesses are increasingly installing solar panels to cut operational costs and improve sustainability credentials.
How Do Solar Panels Work?
Solar panels utilise photovoltaic (PV) technology to convert sunlight into electricity to convert sunlight into electricity, providing clean and renewable energy for homes and businesses.
When sunlight (composed of photons) strikes a solar panel, the silicon cells absorb the photons’ energy. The absorbed energy excites electrons in the silicon cells, causing them to break free from their atoms. The design of the silicon cells creates an electric field that directs the free electrons into a current. The flow of free electrons forms a DC (direct current) that can be harnessed and used. An inverter then converts DC electricity to AC (alternating current), which is compatible with household appliances and the grid.
Here is a rough idea of the components used in solar installations –
- Solar Panels
- Inverter
- Mounting system
- Monitoring system
- Cablings and other essential components.
Types of Solar Panels
There are numerous types of solar panels that are in innovation, here are the top 3 ones that are used widely –
- Monocrystalline Panels
- Made from high-purity silicon.
- Offer high efficiency (15-20%) and performance.
- More expensive but have a longer lifespan.
- Polycrystalline Panels
- Made from silicon crystals.
- Slightly lower efficiency (13-16%) than monocrystalline panels.
- More affordable, and suitable for budget-conscious installations.
- Thin-Film Solar Panels
- Made from flexible layers of photovoltaic materials.
- Lower efficiency (10-12%) but lightweight and flexible.
- Ideal for portable or off-grid applications.
Hence, this is how the panels work and the different types you can choose from for your home or business. In general, monocrystalline panels are the most efficient and preferred type worldwide.
