Solar roof tiles are an innovative and aesthetically pleasing alternative to traditional solar panels. Designed to replace standard roofing materials, solar roofing tiles generate clean energy while serving as a functional roof covering. Roof solar tiles are perfect for homeowners who value sleek, modern designs, integrating seamlessly into a property’s architecture without the bulky appearance of traditional panels.
Many of the benefits and disadvantages of solar roof tiles align with those of solar panels. However, their unique design style means that they have a range of different pros and cons distinct from traditional installations.
In this blog, we’ll explore the costs, benefits and installation process of solar roof tiles for UK homes, touching on everything from financial aspects to functionality. Whether you’re considering a new build, a roof replacement or simply want to invest in renewable energy for your home or business, this guide will provide the insights you need to make an informed decision.
What are solar roof tiles?
Solar roof tiles, also known as solar shingles or solar slates, are cutting-edge roofing materials embedded with photovoltaic (PV) cells that capture sunlight and convert it into electricity. There are also solar thermal roof tiles, which turn sunlight into heat. Unlike traditional solar panels, which are mounted on top of an existing roof, solar tiles integrate directly into the roof structure for a sleek and attractive look. It’s worth noting that some solar tiles for roofs look indistinguishable from regular tiles, while others have an appearance closer to traditional panels.
These tiles are particularly popular for new builds or full roof replacements, as they combine the functionality of a roof with the energy-generating capacity of solar technology. They’re an excellent choice for homeowners, property managers and business owners looking to maintain the architectural integrity of their property while embracing renewable energy.
Key advantages of solar roof tiles include:
- Sleek, integrated aesthetic designs that blend seamlessly into roofs
- Ideal for properties in conservation areas or with strict aesthetic guidelines
- Dual-purpose functionality as both roofing material and energy generator
These basic benefits are why people might install solar roof tiles. However, roof solar tiles cost a fair amount in general, so it’s important to have a clear budget and plan.
Understanding the cost of solar roof tiles
So how much do solar roof tiles cost in the UK? Naturally, not every installation will be the same, with different elements influencing the overall cost of the project. The aspects that are most influential on price are roof size, material, brand, aesthetic design and power capacity in terms of kW. On average, homeowners can expect to pay between £300 and £450 per square metre, with total costs ranging from around £10,000 to upward of £20,000 for a typical UK home.
Brand can have a huge impact in terms of pricing.
- Marley SolarTile. These are simpler solar roof tiles, starting at £2,064.43 per 4-panel set, with installation varying depending on your contractor.
- GB-Sol PV Slate. These tiles have been a mainstay in the UK market for years, costing £225 per square meter or £6,520 for a 4kW system.
- XO Edge. These tiles are a little bit more expensive, costing around £11,000 and £13,500 for a 4kW system including installation costs.
While the brand is a significant element, there are a range of different physical factors that impact the costs of installations, too. These include:
- Roof size. Larger roofs on bigger properties require more tiles, increasing overall costs.
- Material and efficiency. Premium materials and products with higher power output typically cost more.
- Installation complexity. Complex roof designs or steep pitches are harder to install, which can raise labour costs.
If you’re considering installing solar roof tiles, you’ll need to properly consider your home’s requirements. If you’re trying to achieve more comprehensive carbon neutrality for a much bigger home, the project will need to be broader.
Additional solar roof tile costs to consider
When budgeting for solar roof tiles, don’t forget to account for additional expenses that you might have to take on.
Installation costs
Professional installation, essential for any sort of solar roof tile project, generally averages at around £5,000–£7,000 depending on the roof’s size and complexity.
Maintenance
Occasional cleaning and repairs are essential for all sorts of solar panel technology, so it’s important to budget for the maintenance of solar roof tiles now and then.
The tiles themselves might not cost much, but solar panels aren’t going to be a one-and-done type of investment. You could also buy the panels in advance and then pay for installation later on if you need to stretch your budget out. Considering funding options is vital for a successful project.
Do bear in mind that traditional solar panels are less expensive (£5,000–£7,000 installed). However, they lack the visual appeal of solar roof tiles, meaning they won’t maintain the same level of kerbside appeal for the property.
Are solar roof tiles worth the investment?
Solar roof tiles can be a cost-effective choice for creating a carbon-neutral home in the long term. By generating renewable energy, they reduce electricity bills and may even provide a return on investment through energy savings. For even better returns on investment, homeowners can also sell excess solar energy back to the grid. In the UK, homeowners can benefit from government incentives such as VAT relief or grants for renewable energy installations, further improving affordability for solar roof tile installations.
The benefits of solar roof tiles
It’s important to consider that despite the investment barriers, there are plenty of significant benefits to installing solar roof tiles:
Environmental benefits
Solar roof tiles, much like traditional solar panels, contribute to a more sustainable future by reducing reliance on fossil fuels. They help homeowners lower their carbon footprint while promoting renewable energy use.
Financial savings
As touched on earlier, solar roof tiles do offer homeowners a decent return on their investments. The energy savings achieved through using solar power can significantly reduce utility bills over time, making them an economical choice.
Aesthetic advantages
The aesthetics are arguably the standout features of solar roof tiles is their sleek, integrated design. Unlike bulky solar panels, they blend smoothly into the roofline, preserving the home’s architectural appeal. This makes them particularly attractive for properties in conservation areas or heritage homes where traditional panels might be unsuitable.
Durability and lifespan
Solar roof tiles are built to withstand harsh weather conditions, including heavy rain, wind and snow, acting as effective roof tiles in their own right. This makes them a great choice within the UK’s variable climate. Many brands offer warranties of 20–25 years or more, ensuring long-term performance and durability.
The installation process of solar roof tiles
If you’re wondering why installation costs are so high, it’s worth taking into account the steps and their distinct complications.
- Roof assessment. A professional installer evaluates the roof’s suitability for solar tiles, taking into account the steepness and accessibility of the roof.
- Tile removal (if applicable). Existing roof tiles will need to be removed to make way for the solar tiles.
- Tile integration. Solar tiles are installed in place of traditional tiles and connected to the electrical system, which will be the bulk of the project.
Professional installation is essential for optimal energy generation and compliance with UK building regulations.
Challenges that can arise in the installation process
Installing solar roof tiles can present unique challenges that may increase costs, such as:
- Weather conditions like rain or strong winds may delay installation.
- Certain roof types, like steep or irregularly shaped roofs, may require additional planning.
Are solar roof tiles worth it for your home?
Solar roof tiles are a sleek and eco-friendly alternative to traditional solar panels, making them an ideal choice for UK homeowners looking to invest in sustainability with style. While they come with higher upfront costs, their long-term benefits – such as energy savings, durability and enhanced property value – can make them a worthwhile investment.
As solar technology continues to evolve, solar roof tiles are becoming an increasingly popular option for modern homes. If you’re considering making the switch, explore available funding options or consult a professional installer to see if solar roof tiles are the right fit for your property.
