Are you considering installing a 20KW solar system but unsure about how much it will cost in Ireland? Solar power is becoming an increasingly popular choice for homeowners and businesses looking to take control of their energy usage and reduce their reliance on the grid.
A 20KW solar system is suitable for larger households or commercial properties with high energy demands. It offers the potential for significant savings on electricity bills, greater energy independence, and the ability to contribute clean energy back to the grid.
However, understanding the full cost, including equipment, installation, grants, and potential returns, is essential. In this blog, we will explore the 20KW solar system cost in Ireland, factors that affect pricing, and help you determine whether it is the right fit for your energy needs.
How Much Does 20KW Solar System Cost In Ireland?
The cost of a 20KW solar system in Ireland typically ranges between €15,000 and €28,000, depending on several key factors. These include the quality and brand of solar panels, the type of inverter used, roof type, labour charges, and whether battery storage is added. After applying available SEAI grants, the cost can reduce significantly, making it more affordable for both homeowners and businesses.
While the initial investment may seem high, the long-term savings on electricity bills and the opportunity to export excess energy can deliver excellent returns. Investing in solar also increases property value and contributes to a greener, more sustainable future.
What Factors Influence the Cost of a 20KW Solar System in Ireland?
The cost of installing a 20KW solar system in Ireland depends on a range of technical choices and property-specific conditions. Knowing what contributes to pricing can help you plan your budget more effectively and avoid unexpected expenses.
Panel Type and Efficiency
Solar panels vary in quality, output, and price. High-efficiency monocrystalline panels tend to cost more but produce more electricity in limited space. They are ideal for roofs with space constraints or households aiming for maximum performance.
Polycrystalline panels are slightly cheaper but require more surface area to produce the same amount of energy. Choosing a well-known brand with solid warranties can also influence both upfront cost and long-term performance.
Inverter Selection
Inverters play a crucial role in converting solar energy into usable electricity for your home or business. Basic string inverters are less expensive but can affect the entire system’s performance if one panel underperforms.
Microinverters and power optimisers offer panel-level control and better efficiency under shading or varying conditions. These advanced options raise the initial cost but may result in higher energy yields over time. Your property’s layout and shading patterns often determine the best inverter type to use.
Roof Orientation and Complexity
The direction, tilt, and structure of your roof significantly impact installation complexity and cost. South-facing roofs in Ireland receive the most sunlight and offer optimal panel placement. East or west-facing roofs may require additional panels to match performance levels.
Steep, shaded, or older roofs might require structural reinforcements or special mounting systems. Ground-mounted systems are a viable option if roof space is insufficient, but they come with added material and labour costs.
Battery Storage Integration
Battery storage allows you to store excess solar energy for use during evenings or power outages. While not essential, batteries improve energy independence and reduce reliance on the grid. Depending on the size and technology, battery systems can add between €5,000 and €10,000 to your total cost.
They are especially useful for properties with high night-time electricity usage or for those in areas with frequent power interruptions. The added benefit is long-term control over your energy usage and savings on imported electricity.
Grants and Financial Supports
Government incentives like SEAI grants can significantly reduce the net cost of your system. These grants are available for residential and some commercial systems, depending on eligibility. For businesses, the Accelerated Capital Allowance scheme allows full tax relief on qualifying solar investments.
Taking full advantage of these financial supports can make a major difference in affordability. Working with an experienced installer helps ensure you meet all criteria and submit the required documentation.
Conclusion
A 20KW solar system is a smart investment for Irish homeowners and businesses with high energy needs. While the upfront cost can range from €15,000 to €28,000, factors like panel type, inverter selection, battery storage, and available grants all influence the final price. With proper planning, the system offers excellent returns through long-term savings, energy independence, and environmental benefits.
