Majority of Welsh adults open to solar – but myths blocking the sunshine savings
New Energy Saving Trust poll highlights opportunity and confusion over solar installations in Wales
AS the summer solstice nears, bringing the longest day of the year, a new survey by the Energy Saving Trust reveals that more than half of adults in Wales would consider installing solar panels—if cost weren’t a barrier.
In 2024 alone, over 15,000 new solar systems were installed across Wales. Yet despite rising interest, many still hesitate, with confusion over costs and effectiveness shading potential savings.
A poll conducted by YouGov for the Trust found that 60% of Welsh adults would consider solar panels if money were no object. However, 56% said they were put off by installation costs, and a quarter were unsure if panels would reduce their energy bills.
To tackle this uncertainty, the Energy Saving Trust has released updated guidance, including a revamped solar calculator to help households estimate installation costs, savings, and potential income from selling unused electricity back to the grid.
Joanna O’Loan, Knowledge Manager at the Energy Saving Trust, said: “Installing solar panels is a smart long-term investment. They work effectively across the UK—even in Wales—and combining them with battery storage and heat pumps can maximise benefits. The net zero home of the future will be powered by a mix of low-carbon technologies.”
Bright returns and real savings
The average installation cost for a domestic 3.5kWp solar system is now around £6,100, and depending on usage and location, homes in Aberystwyth could save £150–£370 annually on electricity bills.
Excess energy can be sold back to the grid through the Smart Export Guarantee (SEG) scheme, providing homeowners with an additional revenue stream. Adding battery storage—which allows energy to be saved for cloudy days or night-time use—can enhance these benefits. Around 48% of survey respondents said they would consider installing solar battery systems if money were no object.
Battery systems typically cost £5,000–£8,000, but can significantly reduce reliance on the grid, especially when paired with smart energy tariffs.
Environmental boost
While savings are a big driver, environmental concerns are not far behind. Over a third (37%) of respondents said they’d install panels to lower their carbon footprint. Solar can reduce emissions by 700–850kg of CO₂ per year, the equivalent of driving from London to Bristol 26 times.
Despite this, only 14% of Welsh respondents believed solar panels are very effective across the UK. The Trust aims to bust this myth, highlighting that modern panels generate electricity even on cloudy days.
Real-world success
Tim, who installed solar panels and battery storage at his Grade II-listed home in Somerset, reported £1,200 in savings in 2024 alone, by using a flexible tariff and charging batteries overnight.
In Malvern, Beth and Martin use their solar setup to power their home and electric vehicle: “It did take a few small changes—like doing the laundry overnight—but now it’s second nature. Solar has saved us money and made our home more sustainable.”
Try the solar calculator
Householders can now explore how much they could save using the Trust’s updated solar panel calculator, available on their website. By answering a few simple questions, users can receive estimates on installation costs, energy bill savings, and SEG earnings.

New deal aims to unlock Wales’ renewable energy potential
Sector partnership targets 100% renewable electricity by 2035
A NEW deal has been launched to help Wales meet its renewable energy targets while ensuring greater benefits for local communities.
The Renewable Energy Sector Deal will see the Welsh Government and industry work in strategic partnership to unlock the full economic potential of Wales’ renewable energy future.
The announcement coincides with the publication of the latest Energy Generation and Energy Use in Wales report, which shows renewable electricity generation in 2024 was equivalent to 54% of Wales’ electricity consumption.
The Welsh Government has set a target for renewable electricity to meet 70% of demand by 2030 and 100% by 2035. It also aims to deliver at least 1.5 gigawatts of locally owned renewable energy capacity by 2035.
The Sector Deal is intended to accelerate deployment across onshore and offshore wind, solar, marine and hydro projects. It will also focus on strengthening supply chains, developing skills, and ensuring communities across Wales benefit directly from renewable energy developments.
Cabinet Secretary for Economy, Energy and Planning, Rebecca Evans, is launching the deal during a visit to the Morlais tidal energy project on Anglesey.
The Morlais scheme, owned and managed by social enterprise Menter Môn, is set to become the largest consented tidal energy project in Europe. The Welsh Government holds an £8 million equity stake in the project.
Rebecca Evans said: “Our ambition is to become a world leader in renewable energy, creating jobs and green growth to make families in Wales more prosperous and help with the cost of living.
“The current conflict in the Middle East has further highlighted the importance of energy independence. Our Renewable Energy Sector Deal will provide a strong foundation for future delivery, benefiting our economy, environment and energy security.
“The Morlais project shows how sustained partnership can unlock Wales’ natural energy resources and turn them into lasting economic opportunities for local communities and businesses.
“The latest energy report shows we are making progress towards our targets. Combined with the record 20 major renewable projects, totalling 1,400MW, backed in the most recent UK Government Contracts for Difference auction, it is clear we are building a more resilient, renewable-powered future.”
Dafydd Gruffydd, Managing Director of Menter Môn, added: “The Renewable Energy Sector Deal is an important step in accelerating growth in Wales and across the UK.
“It recognises the role marine energy schemes like Morlais can play in strengthening energy security, creating high-quality jobs and delivering long-term economic benefits for communities such as Anglesey.”
The Sector Deal was co-produced by a task and finish group made up of developers and community organisations.
Responding to the Welsh Government’s Renewable Energy Sector Deal, Welsh Liberal Democrat Leader Jane Dodds MS said: “This so-called ‘sector deal’ raises more questions than it answers.
“There is no clear plan for how we build the workforce needed, with no detail on training, skills or apprenticeships to deliver the green jobs Wales needs.
“Ministers also promise benefits for communities, but without minimum standards or enforcement, there is no guarantee local people will see the rewards.
“Most concerning is the lack of focus on energy bills. Families are struggling, yet there is no clear explanation of how this will bring down costs. Renewable energy should mean cheaper bills, but as long as electricity prices are tied to gas, households won’t feel the benefit, something Labour in Westminster has failed to fix.”

Research vessel begins mission to study seabed carbon in Irish Sea
Bangor University scientists join £2.1m project investigating the impact of bottom trawling on carbon stored beneath the seabed
A STATE OF THE ART research vessel has set sail from Liverpool to investigate how bottom trawling may affect carbon stored in the seabed of the Irish Sea.
The scientific expedition is part of a £2.1 million research project funded by the Natural Environment Research Council and led by Professor Jan Geert Hiddink of Bangor University.
A team of eighteen scientists has embarked on the RRS Discovery, one of the world’s most advanced research vessels, for a three-and-a-half-week voyage studying the impact of fishing activity on carbon held in seabed sediments.
Before the ship departed, a number of local dignitaries were invited aboard for a tour of the vessel, including Liverpool City Region Mayor Steve Rotheram and National Oceanography Centre Operations Director Natalie Campbell.
Professor Jan Geert Hiddink, from Bangor University’s School of Ocean Sciences, said bottom-trawl fishing is both vital to global food supply and a major disturbance to seabed environments.
“Bottom-trawl fishing provides around a quarter of global seafood but is also the most extensive physical disturbance caused by human activities to stocks of carbon locked in seabed sediments,” he said.
“This is important because recent evidence suggests that disturbing the seabed could lead to the release of significant amounts of greenhouse gases from the seabed into the atmosphere.
“There are still major uncertainties about how this disturbance affects carbon stored beneath the seabed. As a result, the impact of these disturbances is largely unquantified and currently unregulated.
“The aim of this project is to gain a much clearer understanding of what is happening so that scientists, policymakers and regulators can make informed decisions in the future.”
Seven research organisations are collaborating on the project: Bangor University, the Centre for Environment, Fisheries and Aquaculture Science (CEFAS), Heriot-Watt University, the University of Leeds, Plymouth Marine Laboratory, the University of St Andrews, and Imperial College London.

Green hydrogen plant approved for Milford Haven Freeport site
Major investment expected to boost low-carbon industry and create skilled jobs in West Wales
A MAJOR green hydrogen project planned for the Milford Haven Freeport tax site has taken a significant step forward after developers approved the final investment decision.
Energy company MorGen Energy has confirmed it will proceed with the West Wales Hydrogen project, one of the first schemes backed through the UK Government’s Hydrogen Allocation Round (HAR1) to reach this stage.
The facility will be built within the Milford Haven Tax Site, part of the Celtic Freeport zone covering Pembrokeshire and Neath Port Talbot.
Construction is expected to begin in 2026, with the plant scheduled to become operational in early 2028.
Once completed, the site is expected to produce around 2,000 tonnes of low-carbon hydrogen each year, meeting the UK’s Low Carbon Hydrogen Standard.
The hydrogen produced will support a range of industries, including port operations, manufacturing and industrial heating, as well as use as a chemical feedstock.
Supporters say the development will help reduce carbon emissions while strengthening Milford Haven’s role in the UK’s emerging hydrogen economy.
The project is also expected to create skilled jobs and provide work for local contractors during the construction phase.
Further expansion may be possible in future phases as demand for hydrogen grows, potentially helping establish Milford Haven as a major hub for low-carbon energy production serving South Wales and beyond.
Luciana Ciubotariu, Chief Executive of Celtic Freeport, said the decision marked another milestone for the region.
She said: “MorGen Energy’s decision is another major step forward for the hydrogen economy in South West Wales.
“Projects like this within the Milford Haven Tax Site show how the Celtic Freeport is accelerating decarbonisation while creating high-value jobs.”
The UK Government’s Hydrogen Allocation Round scheme provides revenue support to help scale up the country’s low-carbon hydrogen sector and bring early projects to market.
