Travel around County Kilkenny and the shift is becoming hard to miss.
From family homes in Kilkenny city and Thomastown to properties around Callan, Freshford and Mooncoin, solar panels are becoming a more regular feature on rooftops.
Electricity remains one of the biggest household expenses, more people are switching to electric vehicles and homeowners want greater certainty over their energy costs. That combination is driving steady interest in solar.
So are solar panels worth it in Kilkenny?
For many homes, the answer is yes.
Why More Kilkenny Homeowners Are Choosing Solar Panels
Kilkenny has a broad mix of homes, from older properties and rural bungalows to detached and semi-detached family homes and more modern developments.
Many have good roof space and relatively open surroundings, which can work well for solar. Rising electricity costs and a greater focus on energy efficiency are also encouraging homeowners to look at generating more of their own electricity.
Activ8 has already completed residential solar installations across the county, including in Mooncoin, Freshford, Kilmacow, Thomastown, Radestown and Bennettsbridge.
Do Solar Panels Work Well in Kilkenny?
The climate may be more Castlecomer than Casablanca, but that’s not a problem!
Solar panels don’t need constant sunshine – they generate from daylight and continue to produce power on bright, overcast days as well as sunny ones.
Kilkenny is also located in the southeast of Ireland, the part of the country that generally enjoys the highest sunshine levels. Met Éireann says Ireland typically receives between 1,100 and 1,600 hours of sunshine each year, with the extreme southeast receiving the most.
How Much Could You Save With Solar Panels in Kilkenny?
There’s no single savings figure that applies to every Kilkenny home.
Savings depend on several factors: the size of your system, your electricity usage, roof orientation, how much solar electricity you use yourself and whether you include battery storage.
Your daily routine matters too. A household using more electricity during daylight hours may be able to use more of its solar generation directly.
The best way to estimate potential savings is therefore to look at your actual electricity usage and design the system around your home rather than relying on a generic national figure.
What Solar Grants Are Available in Kilkenny?
Eligible Kilkenny homeowners can currently receive an SEAI Solar PV Grant of up to €1,800 towards an installation.
The grant provides €700 per kWp up to 2kWp and €200 for each additional kWp up to 4kWp. A qualifying system of 4kWp or larger therefore reaches the current €1,800 maximum.
Your home must meet the eligibility criteria and grant approval needs to be in place before work commences.
What Solar Grants Are Available in Kilkenny?
Battery storage allows you to keep some of the surplus electricity generated by your solar panels during the day and use it later.
That can be useful for households where electricity demand is highest in the evening, after solar generation has started to fall.
A battery won’t be necessary for every Kilkenny home. Whether it makes sense depends on your electricity usage, the size of your solar system and when you typically use power.
What If You’re Thinking About an Electric Car?
Electric vehicles are becoming a more common sight on Kilkenny roads, and an EV can make solar particularly relevant for a household.
A record 312 electric vehicles were registered in County Kilkenny in 2025, up from 232 the previous year – an increase of around 35%
An EV can significantly increase a household’s electricity consumption, but if your car is at home while your panels are generating, some of that solar electricity can potentially be used to help charge it.
If an EV is likely to be your next car, it’s worth taking that future electricity demand into account when designing your solar system.
Will Solar Panels Improve My BER Rating?
Solar PV can make a positive contribution to the energy performance of your home and may help improve its BER ratings.
The exact improvement will depend on the property and the other energy-efficiency measures already in place.
For Kilkenny homeowners investigating insulation, heat pumps or other upgrades, solar is often considered as part of a wider approach to improving the home’s energy performance.
Are Solar Panels Worth It for Your Kilkenny Home?
For many households, yes.
The strongest candidates tend to have suitable roof space, reasonable electricity usage and a solar system designed around how the household actually consumes power.
A rural home outside Castlecomer may have very different requirements to a family home in Kilkenny city, so the starting point should always be the individual property.
Frequently Asked Questions About Solar Panels in Kilkenny
Do I Need a South-Facing Roof for Solar Panels in Kilkenny?
No. A south-facing roof can be ideal, but east- and west-facing roofs can also work well. Available roof space, pitch and shading are also important.
How Many Solar Panels Will I Need?
There’s no single number that suits every Kilkenny home. It depends on your electricity consumption, available roof space and future requirements such as an electric vehicle or heat pump.
Can I Add a Battery Later?
In many cases, yes. If you think battery storage may interest you in future, it’s worth discussing that when your original solar system is being designed.
Do Solar Panels Work on Cloudy Days in Kilkenny?
Yes. Solar PV generates electricity from daylight rather than heat. Even on dull days, diffuse solar radiation continues to reach the earth’s surface.
Can Older Homes in Kilkenny Have Solar Panels?
Yes, provided the roof is suitable. The age of the house isn’t the deciding factor – roof condition, orientation, available space and shading are more important.
Thinking About Solar Panels in Kilkenny?
No two homes in Kilkenny use electricity in exactly the same way, which is why no two solar systems should automatically be identical.
With 20 years’ experience and more than 25,000 installations completed across Ireland, Activ8 Solar Energies has helped homeowners generate their own electricity, reduce their reliance on the grid and take greater control of their energy bills.
