Read MoreThinking about adding solar panels to your home in Wales? 2026 is an exciting time for residential solar. With smarter technology, supportive government initiatives, and more ways to save energy and money, solar has never been more accessible.
Before we dive into 2026, let’s take a look back. In 2025, the UK saw a record year for certified renewable installations in homes and small businesses, with 369,000 systems installed.
This record-breaking growth was driven by three key technologies:
Put simply, that equates to one installation every 90 seconds across the UK, according to the Microgeneration Certification Scheme (MCS). This represents a 34% increase compared to 2024 and brings the total number of certified installations since 2009 to 2.4 million, with more than a quarter completed in just the last two years.
The energy potential of these new systems is significant. Installations delivered in 2025 alone are capable of generating around 1.8 billion kWh annually — enough to power the entire London Underground network for a full year. Total installed renewable capacity since 2009 now exceeds 10GW. (https://mcscertified.com/uk-homes-installing-a-small-scale-renewable-every-90-seconds/)
This growth shows that homeowners and small businesses are increasingly choosing solar panels, battery storage, and heat pumps not only for cost savings, but for energy independence and long-term sustainability.
Wales has been a strong contributor to this growth. Areas with the highest number of new solar PV installations in 2025 included:
As we move through 2026, the UK solar market continues to evolve. Technology is more efficient than ever, and demand remains strong as households prioritise energy stability.
While market conditions can fluctuate, the long-term case for solar remains compelling. The current zero-rated VAT on residential solar installations (available until 2027) helps reduce upfront costs, and ongoing energy price adjustments continue to make self-generation an attractive option for homeowners.
For many households in Wales, solar is no longer simply an environmental choice — it is becoming a practical step toward financial resilience and energy control.
Every home is unique, so the ideal solar system depends on several important factors:
A professional site assessment ensures the system is designed specifically around your home’s energy usage and roof layout.
The UK continues to support homeowners investing in renewable energy. Key schemes include:
If your solar panels generate more electricity than your household uses, the excess can be exported to the grid.
Under the Smart Export Guarantee, energy suppliers are required to pay homeowners for exported electricity. Suppliers set their own rates, which creates competition in the market. Some tariffs offer higher returns when combined with battery storage or specific supply agreements.
Households with battery storage may benefit from time-of-use tariffs that allow stored electricity to be exported during peak evening periods.
In most cases, rooftop solar panels in Wales fall under permitted development rights and do not require planning permission, provided installation guidelines are followed.
Flat roofs often offer additional flexibility, and new-build properties increasingly integrate solar as standard.
Working with a certified installer ensures all paperwork, grid applications, and compliance requirements are handled correctly, giving homeowners peace of mind.
Selecting the right installer is essential to long-term system performance. When comparing providers, consider:
A well-designed and properly installed solar system can deliver reliable performance for decades, helping households across Wales reduce bills and move toward cleaner energy.
Some commercial roofs simply aren’t built for traditional Solar PV. They may have strict weight limits, a delicate membrane, or planning requirements that make standard framed panels too heavy or too intrusive.
That’s exactly what we found in Trimsaran, Carmarthenshire. The client wanted renewable energy, but the roof couldn’t take the load of a conventional installation. Instead of turning the project down, our engineering team explored alternatives — and found the perfect match in a Welsh-made peel-and-stick flexible Solar PV system.
It allowed us to deliver clean energy with no drilling, no added weight, and no compromise on the building’s appearance.
During our initial survey, two challenges became immediately clear:
The roof structure could not safely support heavy framed panels or rail systems.
The roof membrane needed to remain completely intact, meaning no fixings, no penetrations, and a visually low-profile installation.
These are the kinds of projects where our engineering team thrives — turning “not possible” into “perfectly achievable.”
To meet the structural and aesthetic requirements, we installed a lightweight, peel-and-stick Solar PV system manufactured in Wales. This technology bonds directly to the roof surface, creating a sleek and durable solar solution without the need for rails, ballast, or drilling.
It’s a smart alternative for buildings that simply cannot host traditional Solar PV — and it’s designed for the UK’s weather conditions.
The building required a solution that was:
Peel-and-stick Solar PV met every requirement — giving the client an elegant, efficient solar installation without affecting the building structure.
For the client, this meant renewable energy with total peace of mind. For us, it was another example of solving a challenge that standard Solar PV couldn’t meet.
Yes — when used in the right circumstances. Peel-and-stick Solar PV is particularly effective for:
They’re not a replacement for traditional Solar PV in every scenario, but they excel when a lightweight, non-invasive solution is required.
| Feature | Peel-and-Stick Flexible Solar PV | Traditional Rigid Solar Panels |
|---|---|---|
| Weight | Very lightweight | Heavy |
| Roof Penetration | None | Requires drilling or ballast |
| Appearance | Low-profile and discreet | Raised and visible |
| Curved Surfaces | Excellent | Poor |
| Suitability for Weak Roofs | Highly suitable | Often unsuitable |
| Low-Light Performance | Very strong | Good |
| Installation Speed | Fast | Moderate |
Every installation is carried out by our in-house MCS-certified engineering team. We never outsource, because projects like this require specialist knowledge, careful planning, and precision.
We specialise in:
If a roof is considered “too difficult” by others, we’re usually the team who can make it work.
Yes — they’re designed for long-term outdoor conditions and include a durable protective surface.
Absolutely. This type of Solar PV responds well to diffuse light, making it ideal for Wales.
No. They require no fixings and keep the roof membrane intact.
Yes — especially where traditional systems are too heavy or intrusive.
Peel-and-stick flexible Solar PV is a game-changing option for commercial buildings that cannot support traditional solar panels. Paired with the expertise of the Solar Save Renewables engineering team, it opens the door for renewable energy on buildings once considered unsuitable.

The primary hurdle wasn’t installing the individual parts, but ensuring they worked together as one intelligent system. Seamless communication between the solar inverter, the battery, and the EV2L system was crucial to avoid inefficiencies and unlock the full potential of their investment.
Our team designed and installed a bespoke system built on synergy:
The Results:
This project in Aberystwyth is a blueprint for the modern, resilient, and efficient home. It proves that by intelligently integrating solar PV, battery storage, and electric vehicle technology, homeowners can achieve significant financial savings and complete energy security.



After 13 years of reliable solar energy, our customer noticed their solar panels weren’t performing like they used to and reached out to us for help. Our inspection revealed two major issues: a malfunctioning inverter and meter, and heavily soiled solar panels.
The Solution:
Replacing the Inverter and Meter:
We replaced the old inverter and meter with new, high-quality upgrades. This upgrade was essential because the inverter transforms solar power into usable electricity, and a faulty meter can mess with energy readings and billing.
Cleaning the Solar Panels:
Our team gave the panels a deep clean, removing years of accumulated dirt. Clean panels are key to absorbing as much sunlight as possible and boosting overall system performance.
With these upgrades and a fresh clean, we managed to give the customer’s system a major performance boost, getting it back to peak efficiency.
Here’s what our customer had to say about the improvements made to their solar system:
“My solar system of 13 years or so was not generating properly. I contacted Solar Save Renewables to assess the problem and quote for a fix. Petar and his team were excellent from start to finish! They replaced the inverter and meter and also cleaned the (very dirty) solar panels. I was kept informed through the whole process. The quote came through very quickly and the work was complete within 6 weeks of the first contact. Highly recommend without any hesitation.”
We recently had the pleasure of working on a project to enhance the energy efficiency of a home in Llandeilo, South Wales.
The property previously relied on oil-fired heating and an electric immersion heater, consuming between 7,000–8,000 kWh annually. Our mission was to reduce their reliance on grid electricity and turn their home into a shining example of energy efficiency.
Here’s how we did it:
We designed a system featuring 10 solar panels facing southeast and 6 panels facing northwest to maximise sunlight capture.
We selected a superior inverter and added power optimizers to ensure every panel performed efficiently, even in the shade.
To complement the 150-year-old Welsh slate roof, we installed sleek, all-black panels that blend seamlessly with the home’s classic look.
They loved how prompt our responses were, how thorough our assessments were, and how meticulously we handled the installation. They found the whole process smooth and stress-free, reinforcing our reputation for quality and reliability in the local area.
Read on for our customer’s experience in their own words:
“I can highly recommend the enthusiasm, passion, and competence of Solar Save Renewables based in Llandeilo, South Wales. 12 years ago, I had a basic solar system installed by others, and although I am a competent amateur when it comes to cost-effectiveness of solar arrays, the time had now come for my parents’ bungalow to have solar installed.
Daily import pre-solar varied from 30 kWh in winter to 18 kWh in summer, totaling 7–8,000 kWh a year. Post-install, solar import has been as low as 6 kWh a day. Of all the companies contacted, only Solar Save Renewables responded promptly, attended when they said they would, carried out a thorough assessment, and were patient with my elderly parents and myself.
The installation, completed about three weeks later, involved a roofer, an electrician, and the owner of the company working for 2½ days. Impressively, at the end of each day, the site was virtually spotless. All team members were professional, knowledgeable, and easy-going.
After-sales service has been excellent. Petar genuinely seems proud of his work, which is reflected in the positive local reviews. This was a virtually stress-free project, and I can totally recommend Solar Save Renewables.”
The Walters praised our team for their professional, knowledgeable service and clear communication. They appreciated the swift, efficient installation and the comprehensive support provided during and after the installation.
“I was initially apprehensive in my search for a suitable company to install a solar energy system at my home. Nevertheless, I came across an advert for Solar Save Renewables, Llandeilo, and arranged a home visit. Within a couple of days of my initial phone call, Petar Pavlov of Solar Save Renewables attended my home and carried out a site survey. From the outset, I was impressed by his professional approach, technical knowledge, and ‘can do’ attitude. He explained everything in layman’s terms and presented a comprehensive quotation suitable for our needs.”
“Within 10 days of signing the relevant paperwork, Petar and his electrician Dan began the installation work. We made a last-minute decision to include an additional storage battery, which was ordered and included without delay. The installation package included a 2-year Home Improvement Protection insurance, an MCS Certificate of competence, and a Building Regulations Certificate. Petar and Diana handled all the necessary paperwork and contact with the National Grid, removing the stress for us.”
“The work was completed in a matter of days with minimal disruption to the daily running of our house. We are very pleased with the system that has been fitted, which includes 12 solar panels together with two storage batteries. I would recommend Petar and his team at Solar Save Renewables to anyone considering a solar energy system.”
Charlie and Glen from Devil’s Bridge, Aberystwyth, sought our expertise to address their rising electricity costs and explore sustainable energy solutions. We stepped in to design, deliver, and install a state-of-the-art 6.00kWp solar PV system, complemented by a 5.8kWh battery storage solution.
Despite facing a series of challenges, our dedicated team expertly navigated every obstacle, ensuring the project was completed successfully and exceeded our customers’ expectations.
The Solution:
When Charlie approached us with the question, “Can I install solar panels on an East-West facing roof?” we knew it would be a unique challenge. East-facing panels optimally catch the morning sun, while West-facing panels soak up the afternoon rays.
To maximise energy generation throughout the day, we installed a combination of East and West-facing panels.
Given the roof’s unique orientation, we chose high-power output panels to ensure efficient energy capture, no matter which direction they face. This smart setup guarantees optimal performance and energy savings.
We also had to manage the relocation of existing ventilation systems and tackle the unexpected challenge of rocky soil in the area.
