Solar Panels Do I Need to Install at My Home Roof to Run Home Utilities

How Many Solar Panels Do I Need to Install at My Home Roof to Run Home Utilities?

As living in the 21st century, Australian homeowners care about global warming and prefer to use solar energy to run home utilities and save on electricity bills. That’s amazing to know about Australian people. But all homeowners feel confused when it comes to installing the solar panel. They worry about how many solar panels they should install on the top of the roof to reach the home electricity requirements.

Their concerns are noticeable as they invest a hefty amount on the solar system. Don’t worry, Aussies Sun Solar is here to help you. Go through the below points and get a clear idea of how many solar panels are enough to be installed on your home roof.

What’s Your Current Electricity Bill?

This matters a lot. First, you need to check your electricity bill for the last couple of months or years. If you can’t get the average figure for every day, you simply divide the monthly bill by 30. So, you will get the actual bill per day. Based on this, a solar system expert can help you choose the right solar system to fulfill your daily electricity requirements.

What’s Your Saving Expectation?

Do you want to reduce your energy cost, neutralize the bill or planning to earn money by sending solar energy back to the main grid? What is your expectation? This is the most important factor you should consider before purchasing a solar panel for your home. Because of your expectation impacts on the number of solar panels you want to install on a home. A few other factors are there too like location and weather conditions.

Where Do You Live?

The solar system thrives on sunlight, no doubt on it at all. Location with more daylight hours (like Perth) will need fewer solar panels to achieve similar result than locations that get fewer daylight hours (like Hobart). Location affects the efficiency of panels. It means solar energy production efficiency may get affected as well.

Before following what your friend living in Perth has done, meet solar system installer at least once to discuss the solar system. It’s FREE. We also recommend you to consult with experts; you will not get disappointed in the future.

What Size of System Fits Your Needs?

Generally, solar systems come with different sizes, for example, 3kW, 5kw, 11kW, etc. You will need to choose the number. Each kW will produce approx. 4 – 4.5 kWh in a day (depending on some other factors mentioned above). To determine the size of a solar system you want, just divide your daily energy consumption by the amount.

Let make it easier for you to understand.

Suppose your daily energy consumption on an average is 14.1 kWh and a 1kW of the solar system produce 4.4kW. Then your need for a solar system is:

14.1 kWh per day / 4.4 kWh = 3.2 (3 kW solar system)

With the above equation, you can easily get an idea of which size fits your needs.

How Many Solar Panels Should You Install?

Once you have decided which solar system or model, your next move would be “how many panels do you install to achieve the needful result?” How would it be calculated?

Generally, standard solar panels come with the output range of 250W to 265W. For your 3kW solar system, you would need at least 12 solar panels for your required 3kW system.

For example, 3 kW / 255* W X 1000 = 11.76. Means need 12 panels.

Remember Bigger is Better Today:

Today, buying a bigger size of the solar system is better due to the lower cost of panels. Other factors are higher feed-in tariffs (FiT) & fast payback on extra kilowatts. If you have required roof space and afford the investment cost, we strongly recommend choosing 5 kWh or higher.

The price ratio between 5kW and 3kW system is narrow and most homeowners can afford the extra amount if they push a little bit further to achieve excessive solar energy output. However, the price for 5kW varies depending on the location you live in.

Remember, the life-span of a solar panel is around 25 years. It means you need to think about the future first as a span of 25 years is not short. The demand for electricity has been increased day by day and so the prices of electricity have been increased. To counter this scenario, the solar system is an affordable, reliable and feasible solution to the Australian homeowners. This way, going bigger is better and of course, worth it.

Still worrying about the size of the solar system you would install at home to counter the conventional electrical energy; call us today at 1800 789 470 ! We would love to hear from you and help to install the right sized efficient solar system.
