Explore the ten solar panel manufacturers we believe are the top brands for solar panel performance, efficiency, price point, reliability, and warranty period. 

There are many solar brands in the market, and having so many options can be overwhelming. However, a quick way to narrow down your options when installing solar panels is to look for solar panels with a great warranty, efficiency, manufacturer reputation, power output and appearance.

These solar manufacturers produce the best solar panels that meet Australian safety and climate standards.

As the CEC approves these panels, they are also eligible for the government’s many solar incentives.

What to look for in a good solar panel?

Before understanding what makes the top 10 solar panels in Australia the best in class you need to know what to look for. Choosing the best solar panels can be challenging for homeowners, so here are the attributes of a solar panel you should assess to make the right choice.  

Here’s what you need to look for:

Solar Panel Efficiency Rating 

The panel efficiency rate refers to the rate at which sunlight is captured and turned into electrical energy.

For example, if the solar panel captures at least half of the solar energy falling on the module, its module efficiency would be near 50%.

The panel does not capture most of the energy stored in sunlight. 

A conventional solar panel’s efficiency ranges from 15% to 21%.

So why is efficiency even important? A solar energy system produces electricity according to its efficiency and panel size.

If a solar panel has high efficiency, it will produce more power per solar module, requiring less space and fewer panels to achieve the same total power output. 

Although high-efficiency solar panels cost more, they are essential for factories or utilities with more significant power needs or residential roofs with less roof space. 

Total Cost of the Panel 

Budget is an important consideration for homeowners when selecting the best solar panel for your roof. 

Besides the solar panel’s costs, you need to consider the cost of solar installation and ongoing solar system maintenance. 

Homeowners also need to consider the cost of retrofitting a battery and whether they need to install a ‘future-proofed system.’ 

Roughly, the total cost of a solar panel system depends on the power output it produces, the complexity of the solar installation, and the additional add-ons such as solar monitoring included in your system.

However, the most significant contributing factor is the solar panel cost. 

Some suppliers offer special discounts from time to time. 

The federal and state governments also offer solar rebates, incentives, and feed-in tariffs, which can help you cover the cost of the solar system.

Beyond that, homeowners can access many no deposit, no interest financing plans that reduce the impact of purchasing a solar system by breaking down the cost of the system into affordable weekly payments. 

Warranty of the Solar Panel

A solar panel warranty refers to the period when the company will replace ta faulty panel, free of charge.

There are two types of solar panel warranties; performance warranties and manufacturing warranties. 

A performance warranty guarantees that the panel will perform according to the 25 linear performance degradation model. A linear degradation model means that the solar panel will be 80% efficient after 25 years and 90% efficient after ten years, and not less than that. This performance degradation will happen gradually and not suddenly.

A manufacturing warranty refers to any faults caused by an improper manufacturing process that resulted in a faulty panel. 

It is essential to compare the warranties provided by solar panel manufacturers as replacing a solar panel can be costly without one. 

However, in many cases, the manufacturer will pay the installer to replace the panel, meaning the cost of re-installing the solar panel is not your responsibility if the panel is in warranty. 

The solar energy industry standard for a performance warranty is 25 years. The average manufacturing warranty is between 10-15 years. 

There are other ways to assess a warranty as well. For instance, find out where to send the module if it needs to replacing or if the company will even be operational in the next 10 to 20 years?

Specifications of the Solar Panel

Solar panels have many specifications, features, and performance metrics that determine their overall quality. One of the most important specifications of a solar panel is power tolerance.

The solar system’s temperature and voltage rating coefficient are critical for assessing the best solar panels, especially for Australia’s hot climate. A temperature coefficient rating is a rating of the panel’s efficiency loss in high temperatures. The better it is, the less energy is lost at temperatures above 40 degrees celsius.

It is also essential that the specifications follow the guidelines of the Clean Energy Council so that you can be eligible for a solar rebate.

Suppose you want a solar panel that can capture as much solar energy as possible and converts it into electricity for your office. In that case, high efficiency should be your primary concern.

But suppose you want a solar panel for your home that you can easily install on your roof and connect with the primary grid. In that case, you need to look for manufacturers of solar or SunPower solar panels to get residential products.

The flexibility of the solar panel and how easily it can be installed is another factor many people consider looking for the best quality panels.

Some manufacturers offer technical support, while with others, you will have to work with independent suppliers for others. Therefore, make sure the company you are working with also has a head office or supporting staff in the country.

Check the Manufacturer’s Tier 1 Status

Many Australians have reported they distrust that panels produced in China are high quality. But the truth is that many Tier 1 solar manufacturers make exceptionally high-quality solar panels in China, with a minority of manufacturers producing lower quality products.

So instead of focusing on the country of manufacturing, you should consider the manufacturer’s reputation in the market. Please read about the solar panel manufacturer online, the responsiveness of its customer service, and the quality of its solar panels.

Some companies also buy solar panels from other manufacturers and self-brand them. Therefore, you should always identify who the product’s actual manufacturer is.

Researching the solar manufacturer online will ensure that you only work with trustworthy and authentic brands. 

It’s also worth mentioning that it’s essential to work with a solar installer or retailer that the Clean Energy Council accredits.

Consider the Appearance

Although this isn’t mandatory, most people also like to think about the solar panels’ appearance and how good the solar panel would look on their roof space.

There are different types of solar panels available in the market. Generally, thin-film solar panels look the best. However, these panels can take up much space.

So if you want something minimal, you can opt for small solar panels. Some solar installers can also integrate the panels directly on the roof, while some suppliers also sell solar roof tiles. 

Many companies have further started to manufacture flexible panels with sleek aesthetics.

However, regardless of your aesthetic, make sure you choose a solar panel that performs well and delivers as promised.
