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.

You probably already know that solar panels are a smart way to cut your energy bills and reduce your carbon footprint. But if you think that’s all they do, you’re only seeing part of the picture. The real power of solar comes from integrating it with other modern home technologies. By pairing your panels with a battery, heat pump, or EV charger, you can create a home that is more self-sufficient, environmentally friendly, and economical.
Here’s a common solar dilemma: your panels produce the most electricity when you’re least likely to be home to use it. Without a way to capture that surplus, it simply flows back to the grid.
This is where a solar battery can help. Think of it as your personal energy reservoir—storing clean, free power during the day so you can use it in the evening when you need it most, for lights, appliances, and family entertainment.

Whether you’re just starting your research or ready to plan, understanding your ideal system size is the best first step towards making solar work for you.
Most people think solar panels are complicated, expensive, or only for eco-warriors. The truth? With the right guidance, they’re a practical, smart way to take control of your energy — and even earn money along the way.
At Solar Save Renewables, we’ve helped hundreds of homeowners across Wales and England unlock the benefits of solar power. This guide provides clear, professional insights into how solar panels work, the true costs and potential savings, how to select the right system for your home, and the benefits of adding battery storage.
Solar panels, also known as photovoltaic (PV) panels, convert sunlight into electricity, making them a popular and eco-friendly choice for generating your own power.
Think of a solar panel as a collection of cells that work together to capture sunlight.
Most panels are made from silicon, a material known for its durability and efficiency. Since there are no moving parts, solar panels can operate for a very long time without wearing out. Plus, they produce electricity – a practical and valuable form of energy for your home.
Imagine sunlight as a stream of tiny energy particles called photons. When these photons hit your solar panels, they transfer their energy to the electrons inside. This process is like giving the electrons a boost, making them jump to a higher energy level.
This energy transfer is what we call the photovoltaic effect, which is why solar panels are named photovoltaic (PV) panels. Essentially, the panels absorb sunlight and convert it into electricity.
The electricity your panels generate can power everything from lights and appliances to electric vehicles. It’s like having a mini power station right on your roof or in your backyard, all fueled by the sun!
At Solar Save Renewables, we understand that choosing the right solar system for your home can feel overwhelming. But don’t worry, we’ll guide you through every step of the process. From assessing your energy needs to selecting the perfect panels, we’re here to make the journey simple and stress-free.

Solar panels are crucial for converting sunlight into electricity. Choosing the right panels can seem complicated, but we’re here to guide you through the process.
When the staff at the local school in Newcastle Emlyn reached out to us, they were unsure about which solar panels would best suit their needs. After assessing their large, south-facing roof and high daytime energy consumption, we recommended high-efficiency Q CELLS panels. “The difference was noticeable right from the first sunny day,” said the school’s headteacher. “Our system produced 15% more than the nearby school that opted for more budget-friendly panels.”
Most panels have black cells with white backs and silver frames. For a seamless look, choose all-black panels with black frames — perfect for slate roofs or integrated installations.
When you invest in solar energy, it’s important to understand how your money is spent. At Solar Save Renewables, we prioritise transparency because we know it builds trust. Here’s how costs are typically distributed:

As energy costs rise and environmental concerns grow, homeowners in Wales are increasingly looking for sustainable and cost-effective heating solutions. Many still rely on traditional gas and oil boilers, but heat pumps vs. boilers is becoming a key consideration for those exploring modern alternatives. In this post, we’ll compare heat pumps and traditional heating systems in terms of efficiency, running costs, and environmental impact. We’ll also discuss how integrating solar panels and battery storage can further enhance your home’s energy efficiency.
If your boiler is ageing, or you’re tired of unpredictable energy bills, you’re not alone. For decades, Welsh homeowners have relied on gas or oil—but there’s a smarter, cleaner, and more efficient alternative: the air source heat pump.
And thanks to the £7,500 Boiler Upgrade Scheme, switching to a modern, low-carbon system has never been more achievable for homes across Carmarthenshire, Pembrokeshire, Ceredigion, Swansea, Mid Wales, and Powys.
This guide breaks down the key differences between heat pumps and traditional systems, highlighting practical benefits, costs, and what makes a heat pump a genuinely sustainable choice for Welsh homes.
| Feature | Air Source Heat Pump | Gas Boiler | Oil Boiler |
|---|---|---|---|
| Efficiency | 300–400% | 85–95% | 85–94% |
| Environmental Impact | Low carbon | High carbon | Very high carbon |
| Running Costs | Low | Moderate | High |
| Lifespan | 20–25 years | 10–15 years | 10–15 years |
Efficiency: Heat pumps move existing heat instead of creating it by burning fuel, giving you 3–4 units of warmth for every unit of electricity.
Lower running costs: High efficiency translates to real savings, especially when replacing old oil or LPG systems.
Long-term value: A heat pump lasts almost twice as long as a conventional boiler.
Sustainable living: Dramatically reduce your household carbon footprint while keeping your home cosy year-round.
Modern heat pumps offer far more than just efficiency:
Energy savings you can feel: In summer, households with well-designed systems can see electricity bills drop to as little as £5 per month, even while charging an electric car.
Income from surplus energy: Pair your heat pump with solar panels, and any excess energy can be sold back to the grid, generating £2–3 per day during sunny months.
Cleaner, healthier homes: Fully electric heating eliminates on-site combustion, improving indoor air quality.
Intuitive control: Modern systems offer smartphone apps for easy temperature and energy management—comfort and control at your fingertips.
To ensure your system performs at its best, keep these factors in mind:
Insulation matters: Well-insulated Welsh homes get the most from heat pumps, with stable warmth and minimal energy waste.
Maximise your investment: Combining a heat pump with solar PV and battery storage creates a home energy ecosystem that slashes bills and carbon output.
Align with your values: If reducing your carbon footprint is important, a heat pump is the most effective home upgrade.
Financial support: The £7,500 Boiler Upgrade Scheme helps offset upfront costs, making the transition far more accessible.
Even if your home currently has gas or oil heating, a heat pump—especially when combined with solar and battery storage—can future-proof your home and reduce ongoing running costs.
