In the past decade, solar panel technology has been improving by leaps and bounds. It’s become so efficient that Australia is now one of the best places in the world to get a solar panel system for your home. So, if you’ve been wondering how much solar panels cost in Australia, this article will help you out.

Solar energy is one of the most cost-effective and clean sources for power generation in a world where natural resources are becoming scarce. It’s no surprise that solar panels have been popping up all over Australia, due largely to government subsidies as well as an increased awareness within our culture about how much waste we contribute with traditional fuels as our main source. If you’re looking at going green with your home or business, there has never been a better reason than now.

Key facts

  • Solar system power prices depend on which region in Australia you reside in and how much sun exposure you may receive.
  • A 6kW system is the most common solar power system, averaging at around $5,000.00
  • Solar rebates, equipment, and the exchange rate all influence the overall price of solar power systems.
  • It’s recommended to search and ask around to find the best solar system prices to suit your lifestyle.

The top 4 factors that impact solar panels costs

Tips for finding cheap solar panels

  • Review your region’s rebate programme: It’s worth calculating your power usage per day, which solar system will supply you with enough power, and how much the government’s rebates will pay for your system as a whole. Remember that if you produce more power than you use, you can earn feed-in tariffs.
  • Search around: Solar panels are an investment that will pay off for years. Not only do they reduce your electric bill, but you can save money in the long run by not paying any fuel costs with solar energy! When shopping around, it pays to research which brands offer top quality equipment at competitive prices- there’s no point in having a system installed if it’s going unused because of higher than expected electricity bills later down the line.
  • Ask friends, family members, and neighbours about their experience: They can inform you of either which installer to go through or which company to avoid. This can help you cut costs without going through trial and error.
  • Always take note of the warranty: Solar panels come with warranties and guarantees from reputable brands. For example, if you purchase a 25-year warranty on your solar system, it will last long enough for the cost of upkeep to pay off itself and give back some profit!
  • The type of panel you use matters: It used to be the case that if you had limited roof space, your only option for generating clean electricity was with highly efficient (and very expensive) mono-crystalline solar panels. This is rapidly changing with advances in polycrystalline panel technology and some thin-film technologies – but even so, many people think about what size of the module will best fill up their roofs before deciding whether or not they want an energy boost!
  • Get several quotes before committing: It is always wise to gather a few solar quotes when making major purchases, as you will find that prices vary widely between providers. But don’t be just swayed by price because inferior components can reduce the upfront cost of your system, and they may wind up costing more long-term if it’s unreliable or inefficient!

Frequently asked questions and answers

  • Is it smart to pay off solar panels?

    Yes, it can be done. The solar panels will pay for themselves on average in Australia. The installation cost is $4,325, but it’s often less than that with rebates and other discounts! With an annual electricity bill averaging at just over 1k per year, you’ll cover your investment within four years time. If you are producing more electricity than your household can use, you can feed into the grid and receive tariffs for the extra power, which can help pay off your solar panels.
  • Do solar panels cost money to maintain?

    Solar panels are an investment that can serve you well for decades, but they don’t mean neglect. A yearly inspection and cleaning are recommended to ensure the continued benefits of this long-term plan. When it’s time to install your solar system or if you need professional maintenance services in order to maintain its condition over the years, you will need to spend money. The average cost to maintain solar panels ranges from $300-$700, with the main expenses being cleaning and inspecting a basic 2KW system on bungalow-style houses
  • Do you really save money with solar panels?

    Yes, solar panels can save you money in the long term. You will reduce or even eliminate your electricity bills! It’s hard for some people who live on smaller budgets than others to see how much their savings add up because they’re not using as many kWh per year. Here is an easy calculation: just over $1k – which covers most families’ monthly expenses with enough left over each month after taxes and spending needs are met – can come from reducing just one household’s usage by 20%. Doing this doesn’t happen overnight, though. Clean energy investments like rooftop deployment still need time before payback becomes viable.
  • How much does just a solar panel cost?

    The cost of installing a solar panel is between $2.67 and $3.43, but it varies based on how big your system needs to be in wattage capacity- measured by energy used per day (or month). There’s also the price for panels themselves, ranging from about $0-$600, each depending on their size. Again, this will largely depend upon roof exposure and efficiency rate. The bigger or more efficient they are, you’ll need less power, so check around before making any purchase decisions!
  • Can a house run on solar power alone?

    With the recent advances in solar energy, it is possible for your house to run solely on this form of power. However, you need a way to store daytime production during nights when there are no sun hours available – which can be expensive at best! Luckily, however, new technologies have made storing batteries affordable enough to become more commonplace in future homes.
