The rising cost of electricity, frequent power outages, and growing environmental concerns have led to a surge in interest among property owners in Brisbane to switch to sustainable energy solutions like solar power. Many homeowners are making the wise decision to install solar systems, but the vast and disorganized solar industry often leaves families unaware of the types of solar panels, batteries, and inverters available like 6.6kW Solar System.
At SolarThoughts™, we aim to educate our customers, not just make a sale. That’s why we’ve prepared this comprehensive guide to help you make an informed decision about investing in a 6.6kW solar panel system.
Why Choose a 6.6kW Solar System?
A 6.6kW solar panel system is a budget-friendly and efficient solution for powering a medium-sized household in Brisbane. It consists of solar panels, an inverter, mounting equipment, and optional solar batteries. With this installation, you can significantly reduce your energy bills, and carbon footprint, and enjoy energy independence.
Every year, Brisbane homeowners spend thousands of dollars on a 6.6kW solar system. It’s no surprise, given that they’re a mid-sized system for residential houses that may cover expenditures ranging from $300 to $500 every quarter. Most 6.6kW systems come with a 5kW inverter, and they are all pretty much pre-approved for grid connections all around Australia.
Is it, however, the best match for your home? A 6.6kW solar system is appropriate for homeowners who consume 15-25kWh per day. If your daily energy consumption exceeds 25kWh, a larger 8kW–10kW solar system may be more appropriate.
Key Components of a 6.6 kw solar system
- Solar Panels: Typically, 16 to 22 panels with wattages ranging from 300 to 400 watts are used in a 6.6kW system.
- Inverter: Converts the DC electricity generated by the solar panels into usable AC electricity for your home.
- Mounting Equipment: Supports and secures the solar panels on your roof.
- Solar Batteries (Optional): Store excess solar energy for use during non-daylight hours or power outages.
How Many Panels in a 6.6kW Solar System?
A 370W solar panel multiplied by 18 equals 6.6kW, depending on the wattage size of the solar panel brand. The higher the individual panel’s wattage, the fewer solar panels you’ll need. The benefits of having fewer panels means that you can fit a bigger system on your roof with the same amount of space. A bigger panel will generally give you slightly better watts per meter squared due to less aluminum framing.
However, getting a larger solar panel has certain drawbacks, such as limiting your system design in terms of how it will fit. Because they output so many more volts than a smaller panel, they might limit your wiring arrangement. When considering the numerous aspects that go into effectively sizing a solar system, choosing the suitable sized solar system for your home is critical.
Roof Space Requirements FOR solar panels 6.6 kw installation
On average, a 6.6kW solar system requires 40 to 55 square meters of roof space. However, this can vary based on panel dimensions and layout. Our experts at SolarThoughts™ can assess your roof and provide a tailored recommendation.
Energy Generation Potential
A high-quality, well-designed 6.6kW solar system in Brisbane can produce approximately 25 to 30 kilowatt-hours (kWh) of electricity per day, which is sufficient to meet the energy needs of an average Australian household. Factors like location, shading, and panel efficiency can affect the actual energy production.
Your 6.6kW system will have varied outputs depending on the state you live in. The peak number of sun hours generated each day on average in your state is used to compute the output of your solar system. For example, the usual peak sun hours in Brisbane are 4.2-4.5 hours per day throughout the year; to calculate how much your system will generate, multiply your peak solar hours by the system size. For a daily use of 6.6kW x 4.2 = 27.72kWh.
Benefits of Adding a Solar Battery
While solar panels generate electricity during daylight hours, a solar battery allows you to store excess energy for use at night or during power outages. Adding a battery provides a reliable secondary energy source and enhances your energy independence.
Cost of a 6.6kW Solar System with Battery
A 6.6kW solar system with a battery typically costs between $12,000 and $16,000 in Brisbane. However, prices can vary depending on the quality of components and the supplier. At SolarThoughts™, we work with reputable manufacturers and offer competitive pricing.
Cost of a 6.6kW Solar System Without Battery
If you opt not to include a battery, a premium-quality 6.6kW solar system in Brisbane can cost between $4,500 and $7,000. Remember to purchase from an approved seller and take advantage of government incentives and tax rebates to get the best deal.
An average price range for a 6.6kW solar installation ranges from $4,500-$8,000 for a quality warranty-backed system, including the Queensland Government rebate incentive. The average cost in Brisbane is $0.94 per watt or $5,660 after the federal incentive.
However, with over 6,000 firms registered with the Clean Energy Council to install solar, the solar business is one of Australia’s most competitive markets. As a result, market margins have been compelled to be razor-thin. Unfortunately, some installers have been forced to forsake product and service quality in order to provide ‘crazy pricing’ and back them with big marketing budgets in order to generate high volumes. These strategies have pushed down prices, but they haven’t improved the situation for consumers in most circumstances.
Should You Invest in a 6.6kW Solar System ?
Absolutely! A 6.6kW solar system is an affordable and efficient solution that can meet the energy needs of most residential households in Brisbane. Not only will you save money on your electricity bills, but you’ll also contribute to a more sustainable future.
How Much Can a 6.6kW Solar System Save Me?
A homeowner that sells 50% of their solar energy back to the grid and consumes the other 50% would expect to save $1,659 annually with a 6.6kW solar system. This assumes that you are selling your power for $0.08 per kWh (a standard feed-in tariff in Brisbane), that you are paying $0.25 per kWh for the electricity that you buy from your energy provider, and that your 6.6kW system is producing 27kWh of electricity a day.
Considering there are some variables, most people fall into three buckets when it comes to their energy usage. A good rule of thumb is that the more energy you can use from your solar system instead of selling, the more you can save.
How Your Energy Usage Affects Your Solar Savings 1 – Low Daytime Usage (30-50%): Estimated annual savings of $1,291 – $1,659 2 – Medium Daytime Usage (50-70%): Estimated annual savings of $1,659 – $1,960 3 – High Daytime Usage (70-100%): Estimated annual savings of $1,960 – $2,463
How Long Does it Take to Pay Off a 6.6 kW solar system?
For an average Brisbane homeowner paying the average price for a 6.6kW solar system of $5,400, it would take around 3.2 years to get your full return on investment.
If paying for a solar system in full is not possible, many solar installers provide fixed-interest financing options. Small loan providers, such as Humm & Brighte, are among the most popular solutions. The length of time it takes to pay off a solar system varies on whether you finance it yourself or use one of these providers.
The advantages of using a finance option allow you to get solar installed sooner rather than later and, in many circumstances, pay less, if not the same, as you did when you paid your electricity bill to your energy providers. In effect, you would be substituting your energy bill with a finance payback plan over a set length of time, often 3-5 years for a 6.6kW.
In many circumstances, most solar owners can pay the same, if not less, than their usual power bill, while the solar system pays for itself over time. If you choose a self-financed solar system, you will have a quicker ROI period of 2.5-3.2 years for a 6.6kW system.
conclusion
In conclusion, investing in a 6.6kW solar panel system is an excellent choice for Brisbane homeowners looking to reduce their energy costs, increase their energy independence, and contribute to a more sustainable future. With the potential to save thousands of dollars annually on electricity bills and various government incentives and rebates available, the long-term benefits of going solar are hard to ignore.
