Types of solar panels

It is essential to understand the different solar panel types and choose the right one for your specific situation. This way, you can maximise your solar energy production, meet your electricity needs, and get the best value for your money.

These are the three main types of solar panels:

  • Monocrystalline panels: Monocrystalline solar panels are popular due to their superior efficiency and longevity. Made from single-crystal silicon, they offer the highest efficiency rates of approximately 20% at a premium price. This makes them ideal for scenarios where space is limited or where the goal is to maximise energy production.
  • Polycrystalline panels: Comprising multiple silicon crystals, polycrystalline solar panels present a modest efficiency range of 16 to 18%. The advantage of these solar panels lies in their cost-effectiveness, serving as a balanced option for residential setups where space is more plentiful.
  • Thin-film panels: Characterised by their flexibility and lower efficiency of around 10-12%, these solar panels are adaptable to a variety of surfaces where traditional panels might not be suitable. While they are the least expensive, they typically require a larger installation area due to their lower efficiency metrics.

How much solar panels cost

The price range for solar panels in Australia in 2024 is quite broad, influenced by factors like system size, component quality, and installation specifics. A standard 6kW residential solar system is priced between $4,000 and $6,000, while the cost of a 10kW setup varies from $7,500 to $10,500. 

Opting for a premium solar panel system, which includes higher-quality solar panels, may cost you an additional 20 to 30%. For instance, premium packages for a 3kW to 10kW set up in cities like Adelaide and Brisbane can range from $4,670 up to $11,540.

Commercial solar installations follow a similar pricing trend, where larger systems tend to offer more value per kW installed. An average 10kW commercial system might hover around $10,050, with slight variations depending on the location. 

For example, such solar power systems might cost around $9,370 in Adelaide and about $9,440 in Perth.

These figures include the goods and services tax (GST) and the Renewable Energy Target’s upfront incentive known as the small-scale technology certificate (STC) discount. 

The overall investment can also be affected by several factors, including the choice of solar panels and inverters, the installation complexity, the property location, and the impact of exchange rates, given that the majority of solar modules are imported.

It’s also worth noting the impact of solar rebates, which can significantly reduce the initial outlay. The rebate value varies by solar panel system size and geographical zone, with a 5kW system rebate ranging from approximately $1,611 to $2,201, depending on your zone.

Criteria for choosing solar panels

Now that we have discussed the best solar panel brands, the different types of solar panels, as well as the price range of solar panel systems, we will also explore the factors you need to consider to make sure you’re selecting the right solar panels for your home or business:

  • Solar efficiency

The efficiency of solar panels indicates how effectively they can convert sunlight into usable electricity. Higher-efficiency panels generate more electricity per square metre of surface area, making them particularly valuable in situations where space is limited or the highest possible power output is desired. Opting for high-efficiency solar panels ensures you can generate the maximum possible electricity, thereby achieving better value for your investment while contributing to sustainability goals.

  • Performance in extreme heat

A solar panel’s temperature coefficient indicates how much its output is reduced when the temperature rises or falls above or below the optimal range. A lower temperature coefficient is better, as it means the panel’s performance is less affected by high temperatures, maintaining better performance on hot days – this is particularly relevant in Australia’s often hot climate, especially in the northern and central regions.

  • Panel size and power output

Panel size and power output directly impact the efficiency and effectiveness of a solar system. Measured in watts, power output indicates how much electricity solar panels can produce under optimal conditions. Larger panels typically have a higher solar power output, which can generate more electricity and potentially cover a larger portion of a household’s or business’s solar energy needs. They might also reduce installation costs by requiring fewer solar panels to achieve the desired system size. However, the available roof space and aesthetic preferences may influence the choice of panel size. It is important to balance these considerations with budget constraints and specific energy requirements to select the most suitable solar panels for your needs.

  • Degradation rate

The degradation rate is a statistic indicated in the solar panel datasheets’ performance warranty section. Solar panel manufacturers use it to calculate and specify the performance warranties, which typically guarantee that the panels will not degrade faster than a certain rate, ensuring they will retain a significant percentage of their solar panel efficiency over the warranty period. For example, a common performance warranty might guarantee that the solar panels will produce at least 80% to 90% of their original solar power output after 25 years. Understanding the degradation rate and how it affects the performance warranty helps you compare the long-term value and reliability of different solar panel brands and models. Panels with lower degradation rates and more favourable performance warranties are generally seen as higher quality and potentially offer a better return on investment.

  • Quality and reliability

The manufacturing quality of solar panels, which includes their physical durability and resilience to weather conditions, ensures long-term reliability and performance under various environmental conditions. Solar panels should also meet Australian and international standards for quality and safety. Certifications can indicate that panels have been tested and meet specific performance and reliability criteria.

  • Manufacturer’s reputation

The Bloomberg Tier 1 rating is an assessment of a solar panel manufacturer’s financial health and bankability. It indicates the manufacturer’s ability to honour warranties over the long term, which is especially significant since solar panel warranties can extend up to 25 years. Given the substantial investment in solar technology and the expectation of its performance over decades, choosing solar panels from a financially stable and reputable solar panel manufacturer ensures that you, the consumers, are protected against potential future issues, such as product failures or warranty claims. This approach mitigates the risk of investing in solar panels from a company that might not be operational in the future to support its products.

  • Warranty

A strong warranty from a reputable manufacturer can serve as an indicator of solar panels’ quality. In Australia, the duration of a solar panel product warranty (also known as a manufacturer’s warranty) typically ranges from 10 to 15 years, with some manufacturers offering extended warranties up to 25 years. As for solar panel performance guarantees, premium solar panels offer a 90% or higher performance warranty after 25 years, compared to the industry average minimum of 80%. 

However, the real value of these warranties depends on the manufacturer’s financial stability and long-term presence in the market – this emphasises the importance of the previous point, which is choosing solar panels from reputable, financially stable companies who are likely to honour their warranty commitments over the long term. Also, make sure that the solar panel manufacturers you’re considering have an office and representatives in Australia. 

This often indicates their dedication to the Australian market; if they do not maintain an office in Australia, warranty claims will be far more challenging.

  • After-sales support

Through reviews and testimonials, gauge customer satisfaction with solar panel companies’ after-sales service, ensuring they provide reliable assistance. Assess how quickly and effectively they respond to enquiries and resolve issues. Also, verify that their technicians have the certification and expertise to diagnose and troubleshoot issues with solar panels. Furthermore, check if they provide easy access through multiple communication channels, such as phone, email, and live chat.

  • Cost vs value

To select the best solar panels at a reasonable cost, it’s crucial to weigh the balance between upfront investment and long-term benefits. While more expensive, as mentioned earlier, high-efficiency solar panels can generate more solar electricity per square metre of roof space – this makes them a wise economic choice for homes and businesses aiming to maximise their space’s power generation potential. In addition, although the initial cost of solar panels with high-efficiency panels is higher, evaluating the difference in power-generating output over a 25-year timeframe is essential. The potential for additional solar power capacity may justify the extra upfront cost of solar panels, offering a better return on your investment in the long term. 


Choosing from the vast array of solar panels in Australia in 2024 requires a thorough consideration of various factors, including the panels’ efficiency, quality, cost, and after-sales support.
