Thinking about switching to solar but unsure about the costs involved? A 16kW solar system is a powerful setup ideal for larger homes or small businesses with high energy usage.
In Ireland, the cost can range between €10,000 to €25,000 depending on equipment, installation, and optional battery storage. Understanding what goes into the pricing can help you make an informed decision.
In this blog, we’ll break down the key factors that influence the total cost of a 16kW solar system.
Let’s start!
How Much Does a 16kW Solar System Cost in Ireland?
If you're considering solar power for a larger home or business, you might be wondering what a 16kW system would actually cost. In Ireland, the average price for a 16kW solar system ranges from €10,000 to €25,000, depending on factors such as panel type, system efficiency, and whether battery storage is included.
Installation complexity and roof design also affect the final price. Government grants, like those offered by the SEAI, can help reduce upfront costs. Knowing the full cost range helps you plan better and weigh your return on investment.
What Are The Key Factors That Influence the Cost of Solar Panels in Ireland?

Understanding the total cost of going solar in Ireland means looking beyond just the panel price. Here’s a detailed breakdown of the main factors.
1. Size and Type of Solar Panels
The cost varies depending on the type and size of the panel system. Monocrystalline panels are efficient but cost more, while polycrystalline panels are cheaper but slightly less efficient.
Thin-film panels are flexible and lower in cost but require more space. Hybrid and BIPV panels offer increased features at higher prices. For example, a 16kw solar system cost in Ireland can vary widely depending on the panel type and technology used.
2. Quality and Brand of Solar Panels
Well-known brands with high-quality standards usually come at a premium but offer better durability and energy yield. Questionable brands may be cheaper but carry performance risks.
Sound-quality panels balance cost and reliability, while premium brands charge more per kilowatt but ensure high efficiency, warranties, and long-term ROI.
3. Installation Costs
Installation expenses depend on factors like labour, equipment, permits, and the system's complexity. Roof condition, tilt, and panel orientation can significantly impact installation costs.
More complex installations or roof structures might increase overall project pricing.
4. Incentives and Grants Available in Ireland
Government incentives such as feed-in tariffs, export tariffs, and reduced VAT can substantially lower the upfront investment.
Ireland also offers grants that reduce total system costs. Understanding available schemes can help calculate your net outlay more accurately.
5. Maintenance and Operational Costs
Beyond the initial setup, solar panels need regular cleaning and occasional repairs. Monitoring systems, replacement parts, and insurance also add to ongoing costs.
Factoring in these operational expenses gives a realistic picture of long-term ownership costs.
What Are The Government Incentives That Reduce the Cost of Solar Panels in Ireland?

Ireland offers several financial incentives to encourage solar energy adoption. These grants and rebates can significantly reduce your overall solar investment.
1. Feed-in Tariff (FIT) and Export Tariff
The Feed-in Tariff lets you sell unused solar energy back to the grid, helping offset your installation costs. The Export Tariff adds further income potential. Together, these schemes can reduce long-term expenses, especially beneficial when considering larger setups like a 16kw solar system cost.
2. Tax Incentives and Rebates
Homeowners in Ireland can claim tax relief through schemes like the Home Renovation Incentive (HRI), which applies to solar installations. In addition, SEAI provides grants through the Better Energy Homes (BEH) and Better Energy Communities (BEC) programmes, making solar panel systems even more affordable.
Conclusion
A 16kW solar system is a significant investment, but one that can deliver substantial long-term savings and energy independence. Costs vary depending on panel type, quality, installation complexity, and available grants or incentives in Ireland. Understanding each factor helps you make a more informed decision and get the best value for your money.
