Solar panels can save money on electricity bills. Learn how they work, the types of installations, and the benefits of going solar in Australia.
Solar panels are devices that generate electricity using sunlight through photovoltaic (PV) cells. These cells are made from materials like silicon, which absorb sunlight and release electrons, creating an electric current. Several solar cells are linked to make a solar panel, and multiple panels are assembled to form a solar array. Solar panels are essential components of a photovoltaic (PV) solar power system.
Before moving ahead, a common confusion in consumers’ minds and the question they ask me frequently is, what is the difference between solar cells and solar panels?
So, let’s understand it with a very basic analogy. Think of a single brick. It’s a valuable building component, but you wouldn’t build a house with just one brick. A solar cell is like this brick, and a solar panel is a complete wall made up of many bricks put together to create a strong structure.

If you’re considering buying components for your solar power system, you might be curious about how to measure the efficiency of solar panels. When we talk about solar panels, their efficiency is measured in percentages. This number indicates how well the panel can convert sunlight into electricity. The panel’s electricity production increases at a higher percentage rate from the same surface area in square meters. However, it’s important to note that high-efficiency panels usually come at a higher cost. A good approach is looking for panels with an efficiency rating of 20% or more to balance cost and performance.
There are many types of solar panels, such as bifacial, thin-film, and perovskite, which CSIRO recently invented. Still, here we will consider the two main types that are mostly commercially used: monocrystalline and polycrystalline.
Nowadays, solar panels have higher wattage outputs than before. Solar panels are rated in watts (W). A higher-wattage panel will produce more electricity and be more extensive and expensive. When choosing the correct wattage for your panels, you must consider the size of your roof and your energy needs.
Selecting solar panels of any random size may not fit your roof well. Solar panels come in various sizes. If you have sufficient roof area, you can go with large panels. The size you need will depend on your roof size and energy needs. Larger panels generate more electricity, but there may be better options if you have a small roof.
The initial cost of solar panels in Australia varies based on efficiency, wattage, size, and brand. Installation costs and transportation charges can also influence the price of solar panels. While the initial cost is an essential factor, consider the long-term value. More efficient panels cost more upfront but can generate more savings over time.
Solar panels are non-mechanical devices that generally last long. Choose panels known for their durability and backed by a strong warranty. A typical warranty lasts 25 to 30 years, indicating the manufacturer’s confidence in their product.
Research the manufacturer’s reputation, including its financial stability, years in business, and customer reviews. It can give you insight into its product quality and customer service. Also, look for the manufacturer’s country of origin. Most of the panels used are from Germany and China. However, you must research the brand and its manufacturing quality before selecting panels.
Understanding the technical specifications of solar panels can be complex for beginners, specifically those new to this market. Many technical terms take work to understand, and many models share similar attributes, making distinguishing between them more complex. Yet, two crucial specs stand out for their impact on performance and let’s make it easy to understand for everyone:
It’s subjective; some people may prefer a specific look that others may not like. It’s your personal choice. However, the choices you have aesthetic-wise are:
Ensure the panels are compatible with your current or planned solar system setup, including the inverter and mounting system.
Clean energy: Solar energy generates clean, renewable power from the sun to combat climate change and air pollution.
Reduced reliance on fossil fuels: Because electricity generation requires sun rays, solar panels, and some renewable devices, you don’t need fossil fuels for some of your total electricity requirements. Hence, by generating your electricity, you lessen your dependence on traditional power plants that rely on fossil fuels.
Conserve Water: Solar energy production requires minimal water, unlike nuclear and coal power plants, which consume large amounts of water for cooling.
Lower electricity bills: Solar panels significantly reduce or even eliminate electricity bills, allowing you to generate energy. You can also pay your utility bills by selling excess power generated.
Increases Home Value: Homes equipped with solar panels sell faster and have higher property values than their non-solar counterparts.
Offers Tax Incentives and Rebates: The Australian Government and Many state governments provide tax benefits, rebates, and incentives to encourage solar panel installation and reduce the upfront costs.
Energy independence: Solar panels give you more control over your energy source, reducing reliance on the grid; by generating your solar power, you depend less on foreign oil and natural gas markets, contributing to national energy independence.
Low maintenance: Solar panels require minimal maintenance. They need cleaning once in a while so that they can operate at their total capacity.
Silent operation: Solar panels generate electricity silently without making noise as no mechanical parts are present in solar panels, unlike generators.
Provides Consistent Energy Supply: Solar energy can provide consistent energy supply, especially during peak load times, reducing the risk of blackouts and enhancing energy security.

The bill would be astronomical if we had to pay the sun for its sunshine! Let’s have a bit of fun with this idea:
The amount of sunshine we receive on Earth is quite significant. The solar constant, which measures solar irradiance at the top of Earth’s atmosphere, is approximately 1370 watts per square meter. However, not all this energy reaches the Earth’s surface due to atmospheric absorption and scattering.
To calculate the value of sunlight received on Earth, we can use the average amount of energy that reaches the surface, which is about 1.4 kilowatts per square meter at peak sunlight. If we were to price this energy, using the same rate of $0.10 per kilowatt-hour, we could estimate the cost of the sun received over a particular area during the peak hours of the day.
For example, if we consider a square meter of the Earth’s surface receiving 1.4 kW for about 12 hours (considering daylight duration), the energy received would be:
1.4kW×12hours=16.8kWh
At $0.10 per kWh, the cost would be:
16.8kWh×$0.10=$1.68
So, for every square meter, the sun would “charge” us $1.68 per day at peak sunlight hours. Multiply this by the Earth’s total surface area that receives sunlight at any given moment,
The Earth’s total surface area is about
510×106 km2
, but only half of this receives sunlight at any given time due to the day-night cycle. So, we’ll use
255×106 km2
for our calculation.
First, let’s convert square kilometres to square meters:
255×106 km2=255×1012 m2
Now, using the cost of $1.68 per square meter per day from our previous conversation:
255×1012 m2×$1.68/m2=$428.4×1012 per day
So, the total “bill” for the sunlight received on Earth would be approximately $428.4 trillion per day.
In perspective, with the world’s total GDP of about $100.562 trillion as of 2022, the daily cost of sunlight would be over four times the annual global GDP. That’s quite an expensive utility bill!
So, Thankfully, the sun doesn’t send us a bill. It’s a good thing sunlight is free, or we’d all be in the dark financially! 😄
