Ireland’s Top Solar Myths Busted (2025 Edition)

Solar power works brilliantly in Ireland, even with our cloudy weather. Many of the old myths about cost, performance, and maintenance simply don’t hold up anymore. In 2025, solar is affordable, reliable, and one of the smartest home upgrades you can make.

Myth 1: “Ireland Doesn’t Get Enough Sun for Solar Panels”

This is the most common misconception and it’s completely false. Solar panels don’t need direct sunlight to generate electricity; they work from daylight, not heat.

Ireland receives an average of 1,100–1,600 sunlight hours per year, which is more than enough to make solar highly effective. Modern panels capture diffuse light on cloudy days, and Ireland’s cool climate actually helps them run efficiently.

Fact: Irish homeowners typically generate 70–80% of their household electricity needs from solar PV across the year.

Myth 2: “Solar Panels Are Too Expensive”

Not anymore. Panel prices have fallen by over 80% in the last decade, and the SEAI solar grant offers up to €1,800 towards installation.

On top of that, the 0% VAT on solar installations (introduced in 2023) means you pay even less.
With lower electricity bills and the ability to sell excess power back to the grid, most homeowners see full payback in 5–7 years.

Fact: Solar power in Ireland has never been more affordable and returns keep improving as energy costs rise.

Myth 3: “Solar Panels Need Constant Maintenance”

Solar panels are virtually maintenance-free. There are no moving parts, and Ireland’s regular rainfall keeps them naturally clean. A quick rinse every 6–12 months and a periodic check by your installer are all that’s needed to keep performance high.

Fact: Solar PV systems come with 25+ year warranties and typically lose only 0.3–0.5% efficiency per year.

Myth 4: “You Can’t Use Solar Power at Night”

Technically true, but that’s where battery storage comes in. With a solar battery, you can store excess energy produced during the day and use it after dark or during power cuts.

Even without a battery, you can still benefit by using smart timers to run appliances when the sun is out.

Fact: A hybrid solar system with battery storage can reduce grid dependence by up to 90%.

Myth 5: “Solar Panels Will Damage My Roof”

A properly installed solar system will not damage your roof. In fact, panels can protect the roof surface from rain and UV exposure. At WattCharger, all installations are handled by SEAI-certified professionals using mounting systems that preserve your roof’s integrity and warranty.

Fact: Panels are mounted on brackets that sit above your roof tiles no drilling through the waterproof layer.

Myth 6: “Solar Doesn’t Work in Winter”

While generation is lower in winter months, panels still produce energy from daylight. Smart system design, including the right tilt angle, inverter setup, and optional battery storage. Ensures your system performs efficiently all year round.

Fact: Even in December, a well-sized Irish solar system can offset a meaningful portion of your electricity use.

Myth 7: “Solar Is Only for Rural Homes”

Urban homes, especially in Dublin and Cork can benefit just as much as rural properties. Solar systems can be tailored to fit semi-detached, terraced, or even apartment buildings with roof access.

With high urban energy prices and excellent SEAI support, solar in cities often delivers faster payback times than in rural areas.

Fact: Solar is for everyone, no matter where you live.
