Choosing the right system for your in Perth or WA is essential
Due to expensive electricity bills and the growing trend of environmental responsibility, more and more homeowners are turning to solar power to run their homes. One of the most popular options for larger households is the 8kW solar system. If you’re planning on investing in solar, you may wonder whether an 8kW system is the best choice for you. Here are a few things you can consider helping you decide.
How Much is an 8kW Solar System?
The cost of solar systems varies, but an 8kW system typically falls in the range of $7500 to $12000. How much you will spend for a system will depend on the quality of the panels and inverters, plus any installation costs in your area. Solar panels at the lower price range often have a shorter lifespan and may not be as durable, while panels at the higher end of the spectrum offer better quality and performance. With that said, the cost of solar systems is steadily dropping every year, so it’s worth checking for deals and discounts before making your purchase.
How Much Space Do You Need for an 8kW Solar System?
The cost of solar systems varies, but an 8kW system typically falls in the range of $7500 to $12000. How much you will spend for a system will depend on the quality of the panels and inverters, plus any installation costs in your area.

With that said, the cost of solar systems is steadily dropping every year, so it’s worth checking for deals and discounts before making your purchase.
How Much Space Do You Need for an 8kW Solar System?
Roof space needed for your solar system installation depends on the number of panels you need to generate the desired power. An 8kW system will require approximately 20-24 PV panels if you’re using modules rated at 330 Watts. More efficient solar panels will require less quantity and roof space.
Prepare at least 65 square feet of usable space on your roof for an 8kW system for the actual measurement. If you don’t have that much available roof space, you may be able to supplement your solar panels with a ground mount or carport installation. You can learn more by speaking with your installers.
How Much Energy Can an 8kW Solar System Generate?
Quality solar panel systems can produce more than four times their rated power output. A high-quality 8kW solar system can generate between 32 and 40 kilowatt-hours (kWh) per day. With that said, weather, location, and the time of year all play a role in how much power your system will ultimately generate. Finding the best position for the placement of your solar panels is also a critical factor.
At a 35 unit/day energy output, an 8kW solar system can offset most, if not all, of a home’s energy consumption. Highly efficient homes can even produce excess energy that you can export to the grid.
How Much Profit Can You Make Using an 8kW Solar System?
If you consider saving money on your energy bill as a profit, you can make a lot of money by installing an 8kW solar system. The more you use the energy your solar system produces, the more money you save. If you use all the energy output for yourself, you can save around $500 per bill cycle.
Solar feed-in tariffs (FITs) are available in several states and territories, which gives you a set price per kilowatt hour (kWh) of solar power generated. The rate varies depending on your location, but you can expect to make between 3 to 10 cents per kWh. You can also profit by selling your system’s excess energy back to the grid.
How Long is the Payback Period of an 8kW Solar System?
The payback period is the amount of time it takes for your solar system to generate enough energy to offset the cost of installation. You’ll earn back your investment in an 8kW solar system within 2.5 to 4 years. However, it still varies depending on how much energy you use to offset your electricity bills. Using your solar system’s entire energy output for yourself significantly shortens the payback period. Whether you’re offsetting all your electrical usage or opt to export energy to the grid, you’re still making a great return on investment.
Should You Install an 8kW Solar System?
When it comes to solar, there’s no one-size-fits-all answer. The best way to see if solar is right for you is by doing your research and speaking with a qualified installer. In general, an 8kW solar system is best for a larger household with more than $500 every energy billing cycle. It’s even more worth it if you plan to use most of the system’s output to offset your home’s energy usage.
