As the solar energy landscape evolves, the role and relevance of 2kW solar power systems have shifted. Once a standard choice for an average Australian home, these systems are now more commonly used for specific smaller-scale applications.
The Composition of a 2kW System
Technology advancements have led to a shift in the composition of 2kW systems. While eight 250W panels were once the norm, the popularity of 415W panels has surged in 2023. This change means fewer panels are needed to make up a 2kW system, a significant advantage for properties with limited roof space.
Power Generation Capacity
Despite their smaller size, 2kW systems can still pack a punch, generating around 8kWh of electricity daily. However, it's important to note that this is now about half the daily electricity usage of a modest Australian home, making these systems more suitable as supplementary power sources.
Cost Savings with a 2kW System
The financial benefits of a 2kW system are influenced by your home's electricity usage patterns. If you can use all the solar electricity produced within your home, you could see savings of approximately $1000 in the first year and potentially $25,000 over two decades, assuming a 5% electricity inflation rate. Exporting half or all of the electricity will result in lower savings, around $650 and $250 in the first year, respectively.
Investment Required for a 2kW System
As of 2023, a 2kW solar power system will set you back between $3,000 and $4,500 after accounting for the solar rebate. However, it's worth considering that you could get a 6.6kW system for more investment, which offers more than triple the capacity for less than double the price.
Return on Investment
The payback period for a 2kW system can be less than four years if all the solar electricity is consumed within the home. This calculation assumes a grid electricity cost of 30c per kWh and an annual electricity price increase of 5%. However, this can vary based on your specific circumstances, including your home's electricity usage patterns and the amount of solar electricity exported.
In conclusion, while 2kW solar power systems may not be the first choice for powering an entire home in 2023, they still have a role to play in the solar energy landscape. Whether you're looking to power a specific application or supplement your home's power supply, it's crucial to stay informed and choose a system that aligns with your needs and circumstances.
