Are Solar Panels Worth It In Ireland?

Are Solar Panels Worth It in Ireland

As experts in the renewable energy space, we often get asked questions about whether solar panels are worth it in a country where days can be grey and rainy, and the short answer is yes, solar panels are worth it in Ireland. You don’t need year-round sun for PV systems to be effective. Although we are aware of the benefits that solar energy holds for the environment and our pockets, we are often left with questions regarding the technology and how exactly it works. For example, does solar energy work well in areas with fewer sunshine hours, or is it only suited to warmer and sunnier climates? 

The fact is, solar panels can work almost anywhere, even somewhere as rainy as Ireland. We have been installing Solar Panels in Ireland from Dublin to Cork and everywhere in between for the past 6 years. Our customers will attest to the suitability of our Irish climate. The reason for this is that most modern photovoltaic or PV solar panels do not use heat from the sun’s rays to produce energy, instead, they convert the invisible UV light into electricity.

Of course, solar panels can be more effective in areas with longer solar days, however, they can be used to supplement a large portion of the electrical energy needs of most households and corporations, even ones based in Ireland.

Installing Solar Panels is an Investment

The world is changing rapidly, and fossil fuels are quickly becoming an unsustainable fuel source. People are becoming increasingly more environmentally conscious. Solar energy is one of the cleanest, most versatile, and renewable forms of energy there is, which makes it the responsible choice when it comes to powering your home. Solar technology has improved in leaps and bounds over the last few years and the solar panels and inverters that are available today are extremely efficient, meaning that smaller solar systems can generate more power. 

Lower Energy Bills

Yes, the main advantage of installing a residential or commercial PV system is reducing your monthly utility bill. However, this is not the only advantage that having solar panels in Ireland offers. Installing a green energy system like PV solar panels increase the value of your property immediately and make it especially interesting to buyers who are looking to live a greener lifestyle. Of course, having a solar-powered home also drastically reduces your carbon footprint which is good for you and the earth.

“Solar panels can lower energy bills by providing a renewable energy source right on your roof, thereby lessening dependence on the energy grid and possibly giving full independence one day. With net metering, homeowners who generate more solar energy than needed can transfer that power to the utility company in exchange for credits that allow them to use traditional energy at no extra cost. It’s perfect for those cloudy days or times when you are using more power than usual and provides a hybrid model so all your energy needs are met. Solar panels can also act as a personal “gas pump on the roof” when homeowners integrate their EV chargers into their solar panel system.” ​

Solar Panels Are Flexible

Solar technology has progressed to the stage where solar power can now be combined with grid power. These systems are referred to as hybrid systems and they give you the best of what both systems have to offer. In areas where solar systems are not able to generate enough energy, a hybrid system offers the option of replacing part of your energy consumption with renewable solar energy. Hybrid grid-tie inverters also ensure that you will always have enough electricity available, come rain or shine. Several more advanced systems even allow you to pump extra energy back into the electrical grid, which can further reduce your monthly utility bill.

"Generally speaking, the more solar panels you install, the less you rely on the grid for power. For example, a 10 kW system will produce more energy than a 6 kW system, giving you more power that you don't have to pay for. That being said, you can install a system that's large enough to run all your appliances throughout the day. Or, you can also install a system that's large enough to cover your needs on the busiest parts of your day and then rely on the grid for calmer hours. The choice is entirely yours. However, do note that while larger solar PV systems save you more money in the long run, the upfront cost of installation is also higher."

"Obviously solar panels do not produce energy when the sun isn’t shining. If connected to the grid, you can still maintain power for your home overnight by pulling from the grid. During high production months like spring and summer, solar panels generally operate at maximum capacity, producing more energy than you can consume in a given month. When you produce excess energy, your system sends that electricity to the grid and every kilowatt-hour you send back will be recorded on your bill as an energy credit. These energy credits are used at times when your system is not producing the energy you need"

The Right System For Every Application

When it comes to solar panels, there is no one size fits all solution. Every scenario is unique, and it is, therefore, important to make sure that you use expert solar installers to plan and execute your solar energy system. Installing solar energy can often come with a high initial cost, this is because the equipment that is required must be purchased and installed upfront before you can enjoy the savings that solar energy brings. Planning your system correctly and choosing the right equipment is essential because it avoids overspending or ending up with a system that doesn’t meet your requirements. Many people ask do solar panels work on cloudy days too and the the reassuring answer is yes.

Integrate with Other Home Appliances

"There is a simple method - you have to connect the panels of the solar system to inverter power and then connect it to the home grid in this way you can easily create a hybrid system"

Solar panels offer a lot of flexibility and inverters are often equipped with specialised software that allows the system to automatically prioritise energy delivery during the day. For example, a typical solar system would use the energy it generates primarily to provide the electrical energy required throughout the day and then recharge storage batteries to provide electricity during the night. Once these goals have been met, excess energy can be used to power EV chargers or supplement home and/or water heating systems.

Can Combine with an EV Charger

If you have already made the switch to environmentally friendly electric motoring, you can further reduce your carbon footprint by combining a solar power system with a domestic EV charger. When using energy harvested from the sun to charge your electric vehicle, you can drive around town for next to nothing and do as little harm as possible to the environment. The smart PV systems and domestic EV chargers from Wizer Energy are compatible with each other and can be paired easily.

"Solar panels can also be used to charge electric vehicles. This is a great way to save money on fuel costs, as well as help the environment by reducing emissions from your car. You can use power from solar panels to charge your car instead of using grid power, or you can use a hybrid system where the solar panels supplement the power from the grid. Either way, you'll be using clean, renewable energy to power your car!"

"Relatively recent innovations also make solar panels an even more beneficial investment! Let’s say you have an electric vehicle (EV) and a home charging port. Most home charging ports are connected to the grid, but if you have solar panels, you can connect them to your home EV charging port. This further helps you save money and live more sustainably.”

"Solar panel systems have recently become more integrated with EV charging. Some SolarEdge inverters come with a Level 2 EV charger built in, and SolarEdge and other companies provide users with the ability to control EV charging in their smartphone apps. As with other power-hungry appliances, an EV charger needs a connection to the grid or a large battery bank to provide consistent power to the car. In the near future, EVs like the Ford F-150 lightning will provide 2-way power flow, meaning they can be charged by solar during the day and provide home backup power at night or during a grid outage."

Can You Save Costs With a Solar Power System

The perceived high initial cost of solar panel installations often scares potential users away from installing the technology. However, while the initial installation costs can be high, PV solar power systems have a long lifespan, and the cost of installation can be recouped easily. To illustrate this, the average household electricity usage in Cork in 2021 was €1006 per annum, however with a 10 panel PV System this becomes €503 per annum, which is a whopping 50% in savings!

In addition to this, solar panel installation in Ireland is made more attractive by the SEAI Grant that the government offers for the installation of green heating and energy production systems. When it comes to the cost of solar panel systems, it is important to take the long view and realise that although you may not see immediate savings, you will in the long run be doing yourself a favour by installing solar energy.

How Much Do Solar Panels Cost?

In recent years, the cost of manufacturing solar panels has been reduced by as much as 80%. The good news is that these savings have been directly passed on to consumers. There are several factors which determine the price of solar panel installation. The more panels you require, the more expensive the installation will be. Furthermore, it’s usually more expensive to add solar panels to older properties.

However, don’t let this put you off. A typical family home with three bedrooms will require a system with 10 solar panels. After taking advantage of an SEAI grant, the final cost of a 10-panel system is around €7,600. But are solar panels worth it in Ireland? Although there is some uncertainty about the rising costs of energy, a 10-panel system can save the average family around €900 per year on their energy bills. Generally speaking, most systems pay for themselves after 7 years.

What’s more, solar panel systems are incredibly durable. Our solar panels are backed by a 30-year guarantee, which is considerably longer than the standard warranty period. Additionally, solar panels require little maintenance, meaning you won’t have to factor in additional running costs.

Solar panels also protect you financially in the long term. As you’re utilising a renewable and abundant energy source, you don’t have to worry about the rising cost of wholesale fuel prices. Solar panel technology can add a premium to property value. A simple solar panel array can yield an increase of more than 4% in your home’s value. As energy price uncertainty becomes more of an issue, expect this premium to soar.

Grants for Solar Panels Ireland

Looking to mitigate the cost of solar panel installation? The good news is that you may be eligible for a SEAI solar electricity grant. To qualify for one of these grants, your property will need to have been constructed and occupied before 2011. However, there are some exceptions. If your property has previously benefited from SEAI assistance, you won’t be able to claim further grants.

Are solar panels worth it in Ireland when grants come into the equation? If you qualify for an SEAI grant, they certainly are. A typical installation can receive assistance worth as much as €2,400. The SEAI provides grant assistance of €900 for every kWp, up to 2kWp. For every additional kWp, an extra €300 in grant assistance is provided. Many PV systems use a battery to store surplus electricity. If you’re thinking about having a battery installed, additional grants of up to €600 can be accessed.

To get started, you’ll need to select a registered SEAI solar PV company like Wizer. Next, make an application for a grant directly to SEAI. Once your application has been received, you should receive a formal grant offer within five working days. Any grant made will be valid for up to 8 months.

Once your solar PV panels have been installed, you’ll need to arrange for a Building Energy Rating (BER) certificate to be completed. This, along with documentation from installation, then needs to be submitted to SEAI. A final application for payment can then be processed. Generally speaking, it will take no longer than 6 weeks for your grant payment to be issued. However, additional inspections are sometimes required, which can delay the process slightly.

Get Paid for Any Extra Electricity You Produce

In 2021, the government unveiled the Micro-generation Support Scheme (MSS). This scheme was developed to encourage homes and businesses to embrace renewable energy generation. However, it also provides the framework for low-level consumers to export any surplus electricity they don’t use. The overall aim of this scheme is to drive Ireland’s micro-generation capacity, providing an additional 2.5GW of solar power to help meet Climate Action Plan objectives.

This also comes as good news for homeowners who’ve invested in solar panel technology. If their systems regularly produce a surplus of energy, they can sell it back to the grid at a small profit. Historically, homeowners have been paid well below market rate for any excess electricity they sell. The MSS strives to make it easier for homeowners to enjoy a more competitive rate for their surplus. The Clean Export Premium (CEP) is currently valued at €0.135/kWh. While this may seem like a low figure, it’s markedly higher than the average wholesale electricity price.

Are solar panels worth it in Ireland? If you’re investing in a large enough solar panel system that includes storage capacity, the answer is yes. As you’ll be selling on your surplus at competitive rates, you can offset rising energy costs elsewhere. Furthermore, you’ll be helping more consumers access clean and renewable energy sources at a time when providers are charging higher rates than ever. 

So, Are Solar Panels Worth It in Ireland?

This brings us back to the original question. Are solar panels worth it in Ireland? The answer is a resounding yes, solar panels are not just worth it in Ireland, they are the smart way to go when it comes to energy generation. Although it may seem like the Irish weather is not conducive to the use of solar panels, Ireland does have enough solar hours to justify the use of PV systems. In fact, it is possible to replace at least 70% of most household’s energy needs with clean solar energy. In the case of commercial solar power installations even higher percentages can be achieved.
