My parents are in their early seventies and live in a detached dormer bungalow in rural Ireland built in the early 1970s - one of thousands of homes that went up during what was often called the bungalow blitz.
Like many houses of that era, it was never exactly renowned for holding heat. Growing up, winter meant layers of clothing, a fire lighting ritual that could take half an hour, and a constant awareness that heat had a habit of disappearing out through walls, windows and anywhere else it could find. “Shut that door after you”, “were you born in a field?”, and “there’s an awful draught” were common utterances as winters were spent mostly decamped to the back sitting room.
Recently I called in for a cup of tea and my parents asked what I’d been working on. When I mentioned writing about solar panels and home energy upgrades, the conversation took an interesting turn.
It quickly became clear that while they’d heard a lot about solar panels, they weren’t short on questions either. Some sensible, some slightly suspicious - and all of them probably shared by thousands of other homeowners across Ireland.
Here are a few that came up. I haven’t covered some of the imaginative ones like “why don’t they put solar panels on windows?”…
This was the first question. And to be fair, it’s not just about solar panels - it’s the same question that gets asked when the washing machine packs in or the car starts acting up.
But it’s one many older homeowners quietly wonder about when it comes to bigger upgrades like solar.
The assumption is often that solar panels are only worthwhile if you’re planning years ahead. But in reality, most systems installed in Ireland today are designed to perform for decades.
Even in the shorter term, they begin generating electricity from day one. That means lower electricity bills immediately rather than years down the line.
For many households, the decision isn’t really about long-term resale value or complicated payback calculations. It’s simply about making the house easier and cheaper to run.
With SEAI solar grants currently available, the upfront cost is also significantly reduced compared with a few years ago — which is one reason many homeowners are choosing to install systems sooner rather than later.
At Activ8 Energies, we regularly work with homeowners in their sixties and seventies who simply want the house to be a bit more comfortable and predictable to run.
Another very common question. Myself and my brothers left the homeplace over twenty years ago, so it’s just the two of them there now. Electricity usage often drops once the house gets quieter, but that doesn’t mean solar panels suddenly stop making sense.
Even smaller households like my parents’ still run the basics every day - lighting, appliances, kettles, washing machines, televisions and increasingly things like heat pumps or electric cars.
Solar systems can be designed to suit the home’s actual electricity demand rather than assuming a large family.
In fact, smaller households often benefit from well-designed systems because they use a good portion of the electricity generated during the day.
And under Ireland’s microgeneration export scheme, any surplus electricity exported back to the grid can earn a payment - meaning unused power still has value.
This is one of the most persistent myths in Ireland. South-facing roofs are ideal, but they are far from essential.
Modern solar systems are frequently installed on east–west roofs, which still generate strong electricity output across the day. Ireland’s long daylight hours during spring and summer mean panels can perform well even without perfect orientation.
When systems are properly designed around the roof layout, shading and usage patterns, many homes that initially seem unsuitable turn out to be perfectly viable.
It’s something installers like Activ8 Solar Energies assess carefully before recommending anything - because the goal is always to design a system that actually works for the house rather than simply filling the roof with panels.
Given the age of many Irish homes, this is another understandable concern.
In most cases, roofs from the 1970s, 80s or 90s are structurally more than capable of supporting solar panels. The panels themselves are surprisingly lightweight and the mounting systems distribute the load evenly across the roof.
What matters more than the age of the house is the condition of the roof structure and tiles.
If the roof is in good condition, solar installation is usually straightforward. If work is needed, it’s typically identified during the initial survey stage before anything proceeds.
This question tends to surprise people.
Standard grid-connected solar systems automatically shut down during a power cut for safety reasons. That prevents electricity feeding back into the grid while engineers may be working on the network.
However, homes that include battery storage and backup capability can continue to power certain circuits during an outage.
This isn’t essential for most households, but it’s an option that some homeowners choose for added resilience.
Another worry is whether the technology will suddenly become outdated.
The reality is that solar panel efficiency improvements have slowed significantly in recent years. The major leaps happened in the early development phase. Today, improvements tend to be incremental rather than revolutionary.
In other words, the panels installed today are unlikely to become obsolete overnight.
Most manufacturers offer performance warranties of around 25 years, and systems commonly continue producing electricity well beyond that.
For homeowners, the bigger factor is simply installing a well-designed system in the first place.
Conversations like the one I had with my parents are happening in houses all over Ireland.
People aren’t necessarily chasing the latest technology trend. They’re simply trying to make sense of rising energy costs, Government grants and the growing number of options available.
For many households, solar panels become one part of a wider energy strategy that might also include insulation upgrades, heat pumps or battery storage.
Companies like Activ8 Solar Energies now help homeowners look at that bigger picture through the SEAI One Stop Shop approach, assessing how a home uses energy before recommending any changes.
In most cases, the real goal isn’t complicated technology, it’s simply a warmer house, steadier bills and fewer surprises.
And if the questions my parents asked are anything to go by, plenty of other Irish households are wondering exactly the same things.
