Everything you need to know about solar panels for your business in Ireland

Are you a business owner in Ireland looking to cut energy costs and become more sustainable? Solar panels are an excellent solution. They help businesses save money on electricity, reduce their carbon footprint, and provide greater energy independence.
In this guide, we cover everything you need to know about how solar panels work, the benefits they offer, their costs, and how you can take advantage of government grants to make the switch easier.
1. What are solar panels?
Solar panels are devices that convert sunlight into electricity. They are made up of photovoltaic (PV) cells that generate power when exposed to daylight. These panels are generally installed on rooftops to supply energy for businesses, reducing reliance on traditional power sources.
2. Why are solar panels important?
Solar panels are important because they help businesses spend less on electricity, keep the planet clean, and rely on their energy instead of the grid. They also reduce pollution, helping Ireland stay green. Plus, customers prefer companies that care about the planet and not just profits, making solar a smart choice for any business.
Top 5 benefits of solar panels for businesses
Solar panels offer many advantages for businesses in Ireland, helping them save money, use energy more effectively, and protect the environment.
Here are five main benefits:
1. Lower energy bills
You can save a lot of money on business energy bills by using solar panels. By making their energy, they can minimise the impact of high electricity rates in the future. For businesses with high energy demands, such as manufacturing or retail, the long-term savings can be substantial.

2. Energy independence
With solar energy, businesses in Ireland can rely less on the main power supply, making their energy more secure. They can also store extra energy in batteries for cloudy days or busy times. This is especially useful for businesses in rural areas or places with regular power outages.
3. Increased property value
Installing solar panels can make your commercial property more valuable and attractive to buyers or renters. As more people care about being eco-friendly, properties with solar panels are in higher demand. Solar-powered businesses usually have lower running costs, which makes them more appealing to investors.
4. Environmental sustainability
By using solar panels, businesses reduce their carbon footprint and help protect the planet. Solar energy comes from the sun, so it doesn’t use up natural resources or harm the environment like fossil fuels do. Businesses that use solar panels are helping to create a cleaner, greener future.
5. Sell excess power
Businesses with solar panels can sell any extra electricity they generate back to the grid. This not only helps reduce energy costs but can also increase savings. By maximising energy use, businesses can get a good return on investment.
How much do commercial solar panels cost in Ireland?
The cost of commercial solar panels in Ireland depends on things like the size of the system, the type of panels, and how much energy the business needs. On average, businesses can pay between €15,000 and €150,000 or more. While the upfront cost is high, businesses save money on energy bills over time. There are also government grants to help lower the initial cost.
Grants for commercial solar panels
The Non-Domestic Microgen Grant (NDMG) helps businesses in Ireland pay for installing solar panels. This grant allows companies to generate their renewable energy, which lowers their electricity costs and reduces their reliance on the national grid.
It also helps businesses become more eco-friendly by cutting down on carbon emissions. The grant is available for systems between 6kWp and 1,000kWp and can be used by all kinds of businesses, sports clubs, public buildings, and community centres. This makes it easier for businesses to switch to green energy and save money while helping the environment.

FAQs
How long do solar panels last?
Solar panels typically last between 25 to 30 years.
Do commercial solar panels need to be cleaned?
Yes, commercial solar panels need to be cleaned from time to time. Dust, dirt, and debris can build up on the surface, reducing their efficiency.
How much electricity can solar panels generate?
On average, a single solar panel can produce between 250 to 400 watts per hour. For a commercial system, which typically includes multiple panels, this can add up to several kilowatts (kW) of power.
Do solar panels only work when it’s sunny?
No, solar panels don’t need just sunny weather to work. Even on Ireland’s cloudy days, they can still produce electricity, just not as much as on sunny days. Solar panels use daylight, not just direct sunlight, so they still work when it’s overcast or rainy.
What is the best direction for solar panels?
The best direction for solar panels is usually south, especially in the northern hemisphere, like in Ireland. If south-facing installation isn’t possible, east or west can also work.
