Choosing the right system for your in Perth or WA is essential
Increasing electricity bills and rising awareness of the importance of clean and eco-friendly energy have increased the popularity of solar power systems. For many homes, a 7kW solar system is a great option. It provides green energy, but it can also offset a large portion of your home’s power usage. But to get the most out of your investment, it’s crucial to consider whether a 7kW solar system is a suitable choice for your home. Regardless of your system’s size, going solar is a great way to reduce your reliance on traditional energy sources and save money on your electricity bills.
How Much Does a 7kW Solar System Cost?
The cost of a 7kW solar system will depend on several factors, including the quality of the equipment, the installer you choose, and any available government rebates or incentives. In Australia, the average cost of a 7kW solar system is around $3,500 before rebates.
However, the cheaper the solar system cost, the more likely it would be of a lower quality installation. For a quality solar system, expect to spend at least $7000. Looking for a reliable and reputable solar installation company can also ensure you get the most out of your investments.
How Big is a 7kW Solar System?
Knowing how much space you need for a 7kW solar system is essential when considering whether this system size is right for your home. A 7kW solar system will take 30 to 50 square meters of space. Naturally, it will depend on how many solar panels you need to install. Typically, a 7kW solar system will have 21 to 28 PV panels. Higher efficiency systems will require fewer modules, while lower wattage panels will need more and take additional space. You can talk to your installers for more information and more detailed requirements for roof space.
How Much Electricity Does a 7kW Solar System Produce?
A solar panel system will produce at least four times its capacity. So, a 7kW solar system will provide you with around 28 to 31 units daily. The usual energy output of a 7kW is enough to offset the electricity usage of an Australian household with above-average power consumption.
The actual energy output will still depend on various factors, including the quality of your solar panels, your location, and the weather conditions. For instance, during winter months or when there are extended periods of cloudy weather, expect a decrease in power output. On the other hand, expect higher energy output during hot summer days.
How Much Can I Save Using a 7kW Solar System?
One of the selling factors of solar panel systems is how much money they can save you on your electricity bills. A 7kW solar system can offset your home’s power usage and significantly reduce your electricity costs. The exact value will depend on how much you use your solar system’s output. Using all of its generated electricity to offset your bills will save you around $1800.
If you’re not using all of your system’s energy output, you can opt to export them to the grid and receive payments from your energy retailer for added savings. However, the best use for maximum savings will be using all of the output yourself.
How Long is the Payback Period for a 7kW?
Whether you use your 7kW solar system’s energy output to offset your entire electrical usage or export some of it, you’re looking at 3 to 4 years of payback period. However, the more you use it yourself, the bigger the savings. The more you save, the faster your investment will pay for itself.
Additionally, the payback period will also depend on how much you paid for your solar system. A more expensive but quality installation will have a shorter payback period due to its higher efficiency and energy output. For this reason, it’s crucial to balance cost with quality when picking a solar system for your home.
Should You Choose a 7kW Solar System?
Are you considering investing in a 7kW solar system? This system is an excellent choice for many reasons. First, it will save you a significant amount on your energy bills. Second, it’s large enough to power most appliances in an average home and offset above-average power consumption. Third, the payback period is reasonable, especially if you use all of the solar system’s output yourself.
If you’re paying around $400 to $500 per energy billing cycle, a 7kW solar system can completely offset your usage and significantly lower your costs. You can even produce energy that you can export if your home is energy efficient.
