Decoding the Price Tag: Factors Affecting Solar Panel Costs in Australia

Several factors affect the pricing of solar panels such as the type of solar panel used, installation process, location and sunlight availability, and rebates. 

Let’s discuss each one of them to help you decide on choosing a solar panel that suits your needs and budget.  

Types of Solar Panels

There are different types of solar panels available in the market, including monocrystalline, polycrystalline, and thin-film solar panels. Here are the advantages and disadvantages of each type. 

Monocrystalline Panels

Monocrystalline panels are made from a single continuous crystal structure and are usually in a dark black colour. These panels are known for their high efficiency at 21% in low-light conditions and space-saving design, but they tend to be more expensive compared to other types of solar panels.

Polycrystalline Panels 

Although not used in the industry much anymore, Polycrystalline panels are made of multiple crystal (silicon) structures with a light or dark blue hue. It takes up a lot of roof space but is more budget-friendly. This panel has lower efficiency rates compared to monocrystalline panels.

P-type versus N-type Solar Panels

The distinction between P-type and N-type solar panels is an essential aspect of modern solar technology, often paralleling the traditional mono vs poly (monocrystalline vs polycrystalline) comparison in terms of quality and cost.

  1. P-type Solar Panels: P-type (Positive-type) panels are the most common in the solar market. They are made using Boron as a doping agent, which gives the silicon a positive charge. P-type panels are generally less expensive to produce and thus more affordable for consumers. However, they tend to have a lower efficiency and a higher rate of degradation over time compared to N-type panels. They are a great option for those seeking a balance between cost and performance.
  2. N-type Solar Panels: N-type (Negative-type) panels use Phosphorus as a doping agent, giving the silicon a negative charge. These panels are known for their higher efficiency and lower degradation rates, making them a higher quality option compared to P-type panels. N-type panels are typically more expensive due to their advanced manufacturing process, but they offer better long-term performance and may generate more electricity over their lifespan. They are ideal for those prioritizing efficiency and long-term value over initial costs.

Bifacial versus Monofacial Solar Panels

The choice between bifacial and monofacial solar panels is another important consideration for those investing in solar energy.

  1. Monofacial Solar Panels: Monofacial panels are the traditional type, with solar cells on one side of the panel only. These panels absorb sunlight from one direction – typically the side facing the sun. They are widely used due to their simplicity and effectiveness in a variety of settings. Monofacial panels are usually less expensive and easier to install and maintain but are limited to absorbing sunlight only from their top side.
  2. Bifacial Solar Panels: Bifacial panels, on the other hand, can absorb sunlight from both sides. This design allows them to capture reflected sunlight from the surface below the panel, in addition to direct sunlight from above. Bifacial panels are typically more efficient than monofacial panels, especially in settings with highly reflective surfaces like white gravel or snow. They are, however, usually more expensive and may require a more complex installation to maximize their efficiency. Bifacial panels are ideal for maximizing energy production in limited spaces or for installations where aesthetic considerations are important.

Both P-type vs N-type and bifacial vs monofacial panels offer distinct advantages and considerations, making it important for consumers to understand their specific energy needs and installation conditions when choosing the right type of solar panel.

Efficiency and Performance

Solar panel efficiency is a huge factor to consider when buying solar panels. Higher-efficiency panels convert more sunlight into electricity and require fewer panels to meet your energy needs. However, higher-efficiency solar panels are expensive, so consider your energy requirements and available roof space before buying one.

Size and Wattages

The size and wattage of solar panels are directly related to their energy production. Normally, solar panels range in size from 1.7m x 1.1m on average and have wattages ranging from about 370 watts to 500 watts per panel. 

Most residential solar power systems range from 6.6 kW systems through to 13.3 kW, which is equal to about 14 to 18 solar panels, depending on their wattage. Larger residential systems can go up to 20 kW or more, depending on your household’s energy needs and the available space for installation.

Installation Process

The cost of solar panel installation varies depending on factors such as your roof’s condition, the complexity of the installation, and the type of mounting system used. Quality installation is crucial to ensure the long-term performance of your solar panels.

Location and Sunlight Availability

Sunlight availability varies across different regions of Australia. The amount of sunlight your location receives impacts the efficiency of your solar panels. Coastal areas and northern regions generally receive more sunlight, making solar installations in these areas more efficient.

Government-mandated Policies

The Australian government offers various incentives and rebates to encourage the switch to solar energy. State and territory governments may offer additional incentives and feed-in tariffs. Understanding the available incentives can significantly reduce the overall cost of your solar panel system.

For example, the Inflation Reduction Act, designed to stabilise the economy, could have various impacts on the pricing of solar panels. Here are some other government-mandated policies you should remember:

  • Regulatory Changes: The Inflation Reduction Act could lead to changes in regulations governing the solar industry. This might affect the standards, safety requirements, or import tariffs that could impact the overall cost structure.
  • Investment in Research: The government may invest in research and development for clean energy technologies as part of economic stability efforts. This can encourage innovation, leading to more cost-effective solar options.

Solar Rebates

Across Australia, various solar rebate programs can significantly reduce the upfront cost of installing solar panels. These rebates, often offered by both federal and state governments, are designed to encourage the adoption of renewable energy by making solar systems more accessible to a broader range of people.

Improving your home’s energy efficiency can impact your solar panel system’s cost. Simple measures like upgrading insulation, using energy-efficient appliances, and sealing drafts can help you reduce your electricity consumption, reducing upfront costs.

Ways To Pay For Solar Panel System Installation

There are several ways to pay for solar panel system installation, each with different advantages and considerations. Here are some common methods:

Out-of-Pocket Purchase

Some solar owners choose to pay for their solar panel systems upfront. They do this by using their savings or taking out a personal loan. This means you pay for the entire system when it’s installed. 

The benefit? You own the solar system immediately and save more money in the long run. Plus, you don’t have to worry about interest payments on loans or leases.

But it’s important to note that this approach requires an investment, which could be challenging for you. Yet, the savings on your electricity bills over time and the chance to benefit from government incentives can help balance out this initial cost.

Incentives and Rebates

We discussed earlier that the Australian government and different state governments provide incentives and rebates and its availability and price varies depending on your location and may change over time.

At SunGain Solar, we understand that investing in solar power is a large financial decision. Aside from government incentives, SunGain Solar can help you find the most suitable financing options to make your switch to solar more budget-friendly. You can guarantee that our team will find the best financing solution based on your requirements. 

Interest Free Solar Loans – Green Loans

We can help provide you with competitive solar financing options called solar or green loans. These financing options come with competitive interest rates and are specifically for solar installations. These loans help you get and pay for solar power over a few years.

With solar loans, you can split the cost into smaller payments over time, which makes solar panels easier on your wallet. What makes this better is that these loans’ interest rates are usually lower than regular personal loans. 

But remember, you have to meet the lender’s requirements, and they might want some security like your property.

Solar Leases or Power Purchase Agreements

Solar leasing and Power Purchase Agreements (PPAs) offer a way for you to have a solar system without the need to buy it. In a PPA, you pay for the electricity the system generates at a rate lower than standard utility bills.

The beauty of these options is that they often involve minimal or no upfront expenses, making solar accessible without the large upfront investment. This setup can lead to immediate savings on your electricity bills. 

But take note that you won’t own the solar panels, and the specific terms and conditions can vary between providers. 

Community Solar Programs

Certain communities provide shared solar programs that allow you to buy a share in a solar installation or subscribe to a system owned by the community. With this choice, you can enjoy the advantages of solar energy without installing panels on your property. It’s a solar energy approach driven by the community as a whole.
