Investing in solar power is an eco-friendly and cost-effective solution for your energy needs. With the cost of living on the rise, more and more Aussies are turning to solar to power their businesses and homes. One of the first questions people ask when considering a solar system is – “How many solar panels do I need?”.
The answer very much depends on a range of factors unique to your needs and property. In this article, we aim to provide you with the necessary information to determine the ideal solar panel system size for your property, ensuring maximum efficiency and return on investment.
The average Australian household requires a solar panel system between 5kW and 7kW, translating to approximately 10 to 22 solar panels. However, this is a rough estimate. The number of solar panels required for your home depends on several factors, including your energy consumption, the efficiency of the solar panels, your location and your budget.
To help you calculate your ideal solar panel system size, consider these factors:
Daily energy consumption: Review your electricity bills to find out your average daily energy usage in kilowatt-hours (kWh). You can also use online tools or consult a solar services professional to get an accurate estimate.
Sunlight hours: The amount of sunlight in your area will affect your solar panel system’s efficiency. You can find the average peak sunlight hours for your location on the Australian Bureau of Meteorology website. Keep in mind that surrounding tree or building may shade solar panels depending on the time of day.
Roof space: When it comes to solar panel installation you are always limited by your available roof space. Always consult a solar technician to determine how many panels you roof can take.
Panel efficiency: Solar panels come in various efficiency levels. Higher efficiency panels generate more power per square metre, meaning you may require fewer panels to meet your energy needs.
Budget: At the end of the day, your budget plays a big part in deciding what size solar system you can afford. While solar panels will save you money in the long run, you need to take up-front costs into consideration.
You can calculate the estimated solar system size needed based on your current usage. This method means you can calculate sizing for both residential and commercial properties alike. As a rule of thumb, divide your average daily electricity usage by 3.5. This is because in Australia, on average, for each one kilowatt of solar panels installed, 3.5 kilowatt hours of solar electricity is generated each day.
