How To Choose Solar Panels | The Ultimate Homeowner’s Guide

Solar panels are now a popular choice for individuals and companies seeking to lower their carbon footprint and save on energy expenses. However, with so many different types and brands of solar panels on the market, choosing the right one can be a daunting task.

Choosing the best solar panels around is difficult due to the vast options available and competing manufacturers’ claims about product superiority. There are key factors to consider such as solar panel efficiency, cost, quality, energy output, and more.

In this article, we will discuss important details to help you make an informed decision in choosing solar panels that matches your needs such as:

Factors to consider when choosing solar panels for your home


A solar panel with higher conversion efficiency can generate more electrical energy compared to a lower-energy efficiency module.

This means you will need fewer panels to produce the same amount of electricity. And, on that note, fewer panels mean lower solar installation costs.

Solar panel cost

Speaking of cost, solar panels in Australia cost around $1000 per kW. So, if you were to install a 10 kW solar system, you should expect to spend roughly $10,000 for your installation.

This price includes the rebates that the government grants to all eligible households. If your home or system isn’t eligible, the cost of your solar panel installation will be much higher.

Quality & warranty

High-quality solar panels in Australia are warranted to be “useful” for 25 years.

This is the standard but, as with anything, this can be different for every manufacturer. Some last up to 30+ years while others will only have warranties of 10 years or so.

High-quality solar panels have a more robust build and can withstand harsh conditions such as hail, high winds, and snow loads. Cheaper panels may be made with lower-quality materials and construction, making them less durable.

Damaged panels may be costly to replace and can lower the overall performance of your solar panel system.


Solar panel manufacturers’ reputations and track records can provide valuable insights into the quality and performance of their products. The solar industry is constantly evolving, and many new companies and products are entering the market every year.

However, not all solar panels or manufacturers are equal in terms of quality and reliability.

So, when choosing a solar manufacturer, one thing to make sure of is that they’re well-established in Australia. Otherwise, you’d have so much trouble claiming warranties in case something goes wrong.

As of writing, there are only 2 Australian-manufactured solar panels in the market but there are other great options sold in the country as well.


Take time to scrutinize the specifications that provide valuable information about the panel’s performance and capabilities. Some of the key specifications to consider include:

  • Solar power ratings can be measured by watts; the higher, the better
  • Efficiency rating talks about how much power the panel is capable of converting into usable electricity; the higher the efficiency is, the more energy it generates
  • Temperature coefficient refers to the amount of energy that is lost as the panel heats up; a lower temperature coefficient is advisable when you choose solar panels

Carefully considering these and other important solar panel specifications can help you select the right solar panels. This also ensures that you’re getting the best possible value for your investment.

Types of solar panels

There are several types of solar panels available on the market, including monocrystalline, polycrystalline, thin-film, and bifacial. Pick the right solar cell type to optimize your energy system.

For example, monocrystalline solar panels are typically more efficient and have good heat tolerance characteristics, but also more expensive than polycrystalline panels.

Thin-film panels, on the other hand, are less efficient but can be more flexible and easier to install.

Solar panel physical features

Some of the key physical features to consider include the solar panel’s size, weight, and mounting options. Solar panel size can affect how much power it can generate, weight affects installation, and mounting options impact the ease and cost of installation.

Most Australian homeowners often choose solar panels with aesthetic designs. It is crucial if you have a strict homeowner’s association (HOA) or if you want to boost your home’s market value.

Other than that, though, how easy they are to install will also affect how much your installer will quote you.

Your solar energy needs

Another thing to consider is your consumption needs to help save energy bills. Knowing how you use energy can help you find the right combinations that work for you.

For example, if you have limited roof space, you might want to consider more efficient solar panels. This way, you generate the same amount of solar energy with fewer modules.

If your roof space still isn’t enough despite highly efficient panels, you may want to consider a ground-mounted system.
