Choosing the right system for your home in Perth or WA is essential
With rising electricity rates and constantly dropping prices of solar panels, now’s the best time to go solar! A 15kW solar system is an excellent option for business or residential property owners who want to reduce energy costs and carbon footprints. A 15kW is the perfect size for larger homes with high power consumption or small-to-medium-sized businesses with large electricity requirements. Here are a few things to consider about whether a 15kW solar system is right for you.
How Much is a 15kW Solar System?
The average cost of a 15kW solar system is around $12,000 to $15,000. Higher quality PV panels with better efficiency will cost more. On the other hand, lower-quality ones will often cost less up-front but may not generate as much electricity over their lifetime. With that said, the constant drop in solar panel prices means you can find good deals on panels. Other factors that can affect how much you would need to spend include the installation, permits, and additional fees associated with setting up the system.
How Big is a 15kW Solar System?
Another crucial factor when deciding what system to get is the required roof space for the system. Depending on the size of the solar panels, a 15kW solar system will need 60 to 90 square metres of roof space. While there are other places you can install solar panels other than the roof, the roof is often the most convenient and efficient spot. If you don’t have enough roof space, another option is to use mounts, leading to more expensive installation costs. You can discuss your options with your installer.
How Much Power Can a 15kW Solar System Produce?
On average, a quality solar system produces around four times its rated capacity. So a 15kW solar system can generate around 60kW daily. However, a few factors can affect the amount of power produced by the system, including the time of day, location, weather conditions, and seasonality. Solar panels usually generate more energy during the summer than in the winter because the sun is higher in the sky.
How Much Can You Save by Using a 15kW Solar System?
A 15kW solar system produces significant savings for businesses and homeowners. The amount of money saved depends on the cost of electricity and how much power from the solar system you use for yourself. You can save at least $1000 per cycle if you use all or most of its energy output. For this reason, you will want to use as much as possible. If you can’t spend all the energy produced by your system, you can also opt to sell them to the grid for a profit.
How Long is the Payback Period of a 15kW Solar System?
Because large solar systems require a high initial investment, many people wonder how long it will take before they start seeing a return on their investment. For a 15kW system, the payback period is usually between five years. The more you save from your electricity bills through self-consumption, the shorter the payback period will be. In many cases, it can be as short as three years. After the payback period, the solar system will generate free electricity for you for around 25 years, the typical solar panel lifespan.
Is a 15kW Solar System the Right Size for you?
When deciding whether to get a 15kW solar system, the most crucial thing you’ll need to consider is your energy consumption. A 15KW solar system is perfect for huge houses and businesses that use 50 to 60kW daily. Roof space is also essential since you’ll need at least 60 to 90 square metres for the system. But if the 15kW fits your home or business, you can expect to see excellent results in terms of savings and return on investment.
