Solar roof tiles
Solar roof tiles are an important part of making your home more energy-efficient and sustainable. In this section, we explain what solar roof tiles are, how they work, and what to consider if you're thinking about using them at home. Whether you're just curious or ready to take the next step, you'll find clear, practical answers without the jargon.
What are solar roof tiles?
Solar roof tiles, also known as solar shingles, are roofing materials that generate electricity. They have built-in solar cells, unlike regular tiles, and replace conventional roofing to provide energy. While they look like normal tiles, they convert sunlight into electricity, which is useful for homes. These tiles tend to be pricier than regular solar panels but offer a more blended aesthetic as part of the roof.
What's the difference between solar roof tiles and regular solar panels?
Solar roof tiles blend into the roof's design and replace normal tiles. They're more expensive and generally less efficient at capturing solar energy. Regular solar panels sit on top of the roof and are cheaper and easier to install, often producing more energy. Choosing between them depends on your roof style, budget, and energy needs.
Are solar roof tiles pricier than regular solar panels?
Yes, solar roof tiles usually cost more than regular solar panels. This is because they combine solar technology with roof materials, making their production and installation more complex. For a typical UK home, solar panels can cost around £5,000 to £6,000, while solar roof tiles may run between £9,000 to £13,500. Consider the look and ease of installation when making your choice.
How do solar roof tiles make electricity?
Solar roof tiles create electricity by using photovoltaic cells. These cells turn sunlight into direct current (DC) electricity when the sun rays hit them. This DC is then changed into alternating current (AC), which is what powers your home or business. Unlike traditional solar panels that are mounted on racks, these tiles are built right into the roof.
Can solar roof tiles work on any kind of roof?
Solar roof tiles can't be installed on every roof. They work best on roofs with a decent pitch, typically between 30 to 50 degrees. Your roof needs to be able to support the tiles, and they integrate best with materials like clay or slate. Local planning rules might also influence your options. It’s a good idea to have a professional look over your roof to check everything's suitable.
Can I put solar roof tiles on an old building?
Yes, you can often install solar roof tiles on older buildings, but it's important to consider several factors. Check if your building is listed or needs special permissions. Solar tiles can blend in with traditional roofs and maintain the building's look. However, they can be more expensive than regular solar panels. Consult your local planning authority to make sure it's allowed in your area.
Do solar roof tiles need much upkeep?
Solar roof tiles don't need a lot of upkeep. They're built to last, handling normal weather conditions well.
