Choosing the right size solar system for your home is crucial to maximizing the benefits of solar energy. Whether you live in Melbourne, Sydney, Brisbane, Adelaide, or Perth, understanding how to size a solar system correctly can save you money and reduce your carbon footprint. This guide will walk you through the steps to determine the ideal solar system size for your home, taking into account seasonal variations in energy usage and solar generation.
Understanding Your Energy Needs
The first step in sizing a solar system is understanding your household's energy consumption. Here’s how you can do it
1. Review Your Electricity Bills
- Look at your electricity bills over the past year to understand your average monthly and daily energy usage in kilowatt-hours (kWh). This will help you see patterns and determine your peak energy consumption months.
2. Calculate Your Daily Energy Usage
- Add up your total annual energy usage and divide by 365 to get your average daily energy consumption. For example, if your annual usage is 7,300 kWh, your daily usage is 20 kWh (7,300 ÷ 365).
However, instead of calculating this yourself, you can get in touch with us, and one of our specialists can design a system perfectly suited to your needs.
Factors Influencing Solar System Size
Several factors influence the size of the solar system you need
1. Location and Climate
- Solar panels generate different amounts of electricity depending on your location and the amount of sunlight your area receives. For instance, Brisbane typically receives more sunlight than Melbourne, meaning solar panels in Brisbane will produce more energy.
2. Roof Space and Orientation
- The amount of available roof space and the orientation (north-facing is ideal in Australia) will affect how many panels you can install and how efficiently they will produce energy.
3. Energy Usage Patterns
- Consider when you use the most energy. Homes with higher daytime usage can benefit more from solar energy as they can use the electricity as it is generated, reducing the need for storage or grid reliance.
4. Future Needs
- Think about future changes that might increase your electricity consumption. Switching from gas to electric appliances, buying an electric car, or running appliances like ducted heating and cooling will increase your household's electricity needs. Planning for these changes now can help ensure your solar system will meet your needs in the long term.
Winter vs. Summer Usage and Solar Generation
Seasonal variations play a significant role in solar energy production and consumption
1. Summer
- During summer, solar panels generate more electricity due to longer daylight hours and more intense sunlight. For example, a 6.6kW system in Melbourne can produce around 25-30 kWh per day in summer, which is often more than enough to cover daily usage.
2. Winter
- In winter, solar generation decreases because of shorter days and lower sunlight intensity. The same 6.6kW system in Melbourne might only produce around 10-15 kWh per day in winter. It's essential to size your system to cover your winter usage to ensure year-round energy savings.
Average System Size in Australia
It's worth noting that the average system size installed in Australia is now over 9kW. This trend reflects a growing desire among households to be more self-reliant and prepared for future increases in electricity consumption. Larger systems can cover more of your energy needs, even during peak usage times or less sunny periods.
Example of a Well-Sized System
To give you an idea, here’s a quick example:
- Average Daily Usage : A family in Sydney uses 20 kWh per day.
- Winter Production : In winter, a 6.6kW system in Sydney can produce about 10-15 kWh per day.
This means a 6.6kW system may not fully cover the energy needs of an average family in Sydney year-round, particularly during winter months. To ensure full coverage, a larger system, such as a 9kW system, might be necessary.
