Are you a business owner in Ireland and tired of rising energy bills impacting your business? Wondering if there's a better way? Solar energy might just be the solution you're searching for. 

In this blog post, we will explore the costs associated with commercial solar panels in Ireland, covering everything from the initial investment to the potential savings that they can bring to your business. 

We’ll break down the factors influencing costs, provide a detailed cost analysis, and discuss how to choose the best solar panel provider. So, let's find out whether solar power is right for your business.

Why Solar Energy is a Wise Investment?

Solar energy is becoming a popular choice for businesses all over the world, including in Ireland. Here are a few simple reasons why companies are turning to solar power:

Good for the Environment: 

Solar panels generate power from sunlight, a clean and endless source of energy. This means they don't produce harmful pollution or greenhouse gases that can damage the environment, unlike traditional power sources like coal or gas.

Saves Money: 

Once you install solar panels, you can significantly reduce your electricity bills. The sun's energy is free, so you only have to pay for the installation. Over time, the savings on your energy bills can really add up, helping your business keep more of its earnings.

Government Support: 

The Irish government offers various incentives for businesses that choose solar energy. These might include tax breaks, grants, or other financial help that can make installing solar panels more affordable.

What is Commercial Solar and How Does It Work?

Commercial solar involves installing solar panels on business premises to generate electricity, rather than in homes. These systems are typically larger and generate more power to meet the high energy needs of businesses.

Here’s a simple breakdown of how it functions:

Solar Panels: 

These devices capture sunlight and convert it into electricity.


Inverters convert the electricity from direct current (DC) to alternating current (AC), which is used in businesses.

Electrical Systems: 

The converted electricity is then used to power the business, and any excess can be sent back to the electricity grid, sometimes earning credits.

Monitoring Systems: 

These allow businesses to track electricity production and ensure everything is working smoothly.

Switching to solar can be a smart move for many businesses, offering benefits that include lower energy costs and contributions to a cleaner environment. 

What Are the Factors Influencing the Cost of Commercial Solar Panels?

When planning to install commercial solar panels, several factors will determine the overall cost. Here’s what affects these costs:

How to Determine the Size of the Solar System?

The cost of solar panels is largely based on their capacity, which is measured in kilowatts (kW). Larger systems that produce more electricity are more expensive. Generally, the more kilowatts you need, the more you will pay upfront, but larger systems are often more cost-effective over time due to economies of scale.

What are the Types of Solar Panels?

  • Monocrystalline Panels: 

These are high-efficiency panels made from a single, pure crystal structure. They are more expensive but generate more power from a smaller area.

  • Polycrystalline Panels: 

These panels are made from multiple crystal fragments. They are cheaper than monocrystalline panels but they are also slightly less efficient.

  • Thin-Film Panels: 

The least expensive and least efficient option, these panels are made from layering thin films of photovoltaic material. They are flexible and perform better in low-light conditions.

What are the Installation Complexities?

  • Roof Type: 

Costs vary with roof design; flat roofs might need special mounts, while steep roofs might need more labour for safe installation.

  • Building Height: 

Higher buildings require more safety measures, increasing costs.

  • Access and Infrastructure: 

Difficult access or need for additional infrastructure can raise installation costs.

What are the Location-Specific Factors?

Sunlight Exposure: 

Solar efficiency depends on local sunlight levels; more sunlight means more power and faster returns on investment (ROI).

By considering these factors, businesses can better understand the initial and long-term costs associated with commercial solar panels, helping to understand whether solar energy is right for their needs.

What Does It Cost to Install Commercial Solar Panels in Ireland?

The cost of installing commercial solar panels in Ireland can vary widely depending on several factors, such as system size, panel type, and installation details. Here's a detailed analysis of the costs involved in commercial solar panels:

Upfront Costs

The cost of solar panels can range from €200 to €500 per panel, depending on the type and efficiency. Inverters typically cost between €1,000 and €2,000. Overall, for a medium-sized commercial system (e.g., 50 kW), the total upfront equipment cost can range from €40,000 to €70,000.

Installation Costs

Installation labour costs can vary, but typically run around €0.75 to €1.25 per watt. For a 50 kW system, this translates to approximately €37,500 to €62,500. The cost for mounting systems and other installation materials can add an additional €5,000 to €10,000.

Initial Setup: 

This includes costs for integrating solar systems with existing electrical setups and ensuring compliance with local codes, potentially adding an additional €2,000 to €5,000.

Operational Costs

Annual maintenance costs are typically about 1% of the total system cost, or approximately €800 to €1,400 for a 50 kW system. Repairs can vary but having a contingency plan for unexpected issues is wise.


Costs for future upgrades depend on technology prices at the time and the nature of the upgrade.

Hidden Costs

Permitting fees can range from €500 to €1,500, depending on local municipality requirements. Inspection costs can add an additional few hundred euros.

Increased Insurance Premiums: 

Installing solar panels might increase insurance premiums by a small percentage; this will depend on the insurer and the specific policy details.

What is the Total Estimated Cost?

For a typical 50 kW commercial solar system in Ireland, you might expect total initial costs (including installation) to be in the range of €85,000 to €150,000. This estimate includes all equipment, installation, and initial setup costs but does not include ongoing maintenance or potential hidden fees like increased insurance.

Investing in solar technology not only helps reduce operational costs over time but also supports sustainability goals. With the right planning and consideration of these cost factors, businesses in Ireland can effectively evaluate the feasibility and potential benefits of solar energy solutions.

Is Investing in Commercial Solar PV Panels a Smart Choice for Your Business?

Whether commercial solar photovoltaic (PV) panels are worth the investment depends on several factors, but for many businesses, the answer is yes. Here’s why investing in commercial solar PV panels can be highly beneficial for businesses:

Cost Savings: 

Commercial solar PV panels offer significant reductions in electricity bills.

Quick Payback (ROI): 

The initial costs are typically recovered within a few years through savings and government incentives.

Property Value: 

It increases the market value of your property.

Environmental Impact: 

Commercial solar PV panels reduce carbon emissions and enhance brand reputation.

Energy Independence: 

It also protects against fluctuating energy prices and supply issues.

So, investing in commercial solar PV panels is generally a smart choice that can lead to significant financial gains and a positive environmental impact.


In Ireland, commercial solar panels offer businesses a sustainable and cost-effective solution to rising energy bills. By using the light and power of the sun, companies can not only reduce their carbon footprint but also enjoy significant long-term savings. However, knowing about the factors influencing costs, from system size to installation complexities, is key to making a wise decision.
