Factors that Affect Solar Panel Costs in Brisbane

Cost is typically one of the most important factors for homeowners who want to invest in solar. There are a few key factors that affect your total cost in Brisbane: solar equipment and system size, financing options and the solar installation company you choose. We’ll go over each of these briefly below.

Solar Equipment

When it comes to estimating the price of a solar panel system in Brisbane, one of the most crucial factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are largely based on your home’s energy consumption, which you can figure out by looking at past electricity bills. Your overall cost can increase by about $3,470 for each additional kilowatt you need.There are a lot of different solar panel brands and the one you pick also changes the cost. In many cases, the brands that are more efficient tend to also be more expensive. In addition, the type of equipment you want to install can affect your total cost. If you just need panels, your system will be much less expensive than if you also need solar batteries or an electric vehicle charger.

Solar Financing Terms

For some homeowners, paying for a solar system out of pocket can be challenging. Solar loans are offered by most installers in Brisbane, which can lower, or in some cases totally eliminate, your upfront costs to make solar more affordable.Though solar loans make adopting solar energy more accessible for Brisbane homeowners, they can also raise the total you pay for your system, depending on your interest rate and how long you take to pay off the loan. If you put down a larger down payment, though, you can avoid paying as much in interest.

Solar Panel Installation Company

The solar installer you opt for to handle your switch to clean energy can have an effect on your total costs. There are about 3 solar panel companies in Brisbane, and each can charge varying amounts for labor and equipment.Larger national companies typically have lower costs, but some local companies compete with them by promoting sales and discounts. While the smaller companies might not have access to specific equipment options like Tesla Powerwall batteries or additional services like electric vehicle charger installation, they might be cheaper overall.

How to Save on Solar Panels

Since the brand of solar panels and the company you choose has an impact on your costs and your system’s durability and efficiency, it’s important to select the right ones for you. Here are some things to keep in mind to help with your decision:

  • Solar Panel Brands: Each solar panel brand and model offers varying levels of quality, longevity and efficiency. They will come at different costs as well. The company you choose has an impact on which solar panel brands you have access to.
  • Warranty: If you care about the durability of your solar energy system, making sure your company offers a 25-year, all-inclusive warranty can give you some peace of mind.
  • Reputation: Well-established companies likely have a solid reputation. This is important because it ensures that it will not only see your solar project through, but will also provide quality aftercare and customer service, such as part repairs and replacements.
  • Installation Process: When going solar, it’s essential to keep an open line of communication with your solar installer. Confirm that you understand how the installation process will go and the completion timeline.

EcoWatch's Brisbane, CA Solar Cost FAQs

How much does it cost to install solar panels in Brisbane?

The average cost of solar panels in Brisbane is about $17,350 for a 5-kW system and $34,700 for a 10-kW system before the ITC, but the actual cost will depend on stuff like the kind of solar panels you want, what size system you need and how much energy you consume.

Is it better to lease or buy solar panels in Brisbane?

Leasing solar panels can be an option if you can’t pay upfront or get a solar loan, but since you don’t own the system, you don’t have access to many solar incentives. Also your home value won’t increase, so you’ll have less savings over time. If you can afford to buy a solar system upfront, then buying is the better option if you want the most financial benefits from going solar.

Can solar panels significantly reduce my energy bills?

It is possible to eradicate your electricity bills with solar panels, but for most homeowners in Brisbane, that will require at least a 10-kW system. Not all homes will have roofs that can accommodate that size system, so you’ll want to contact a local solar installer to see how many panels can fit on your roof.

How long do solar panels last in Brisbane?

Even though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they are completely unusable at that time. What this means is the amount of energy they produce will have decreased significantly after that point. You can opt to replace them once you've had them for that long or you can continue to use them at a lower efficiency.
