Solar Roof Tiles

Solar roof tiles provide a way to generate electricity without fitting conventional solar panels on top of the roof. Instead, photovoltaic cells are incorporated into the roof covering itself. Solar tiles can be particularly suitable for new-build properties or homes that already require a roof replacement, as they can be installed as part of the roofing work.

Solar roof tiles work in a similar way to conventional solar photovoltaic panels. They convert energy from sunlight into electricity, which is then sent to an inverter. The inverter converts the direct current (DC) electricity produced by the solar system into alternating current (AC) electricity that can be used within the property.

The amount of electricity generated by solar roof tiles will depend on factors such as the orientation and pitch of the roof, the efficiency and number of photovoltaic tiles installed, shading and the amount of sunlight the property receives. Because the solar tiles form part of the roof covering, installing them when constructing a new roof or replacing an existing one can make the installation more straightforward.

Solar roof tiles can also appeal to homeowners who prefer a more integrated appearance than conventional solar panels. However, planning restrictions can still apply, particularly on listed buildings or properties in conservation areas, so you should check the relevant requirements before installation.

Solar roof tiles can reduce the amount of electricity you need to purchase from the grid by allowing you to use electricity generated at your property. Actual savings will depend on the size and performance of the system, how much electricity you use while it is being generated and your electricity tariff.

The Feed-in Tariff scheme is closed to new applicants. However, eligible households with solar photovoltaic systems may be able to receive payments for electricity exported to the grid through the Smart Export Guarantee (SEG). The amount paid will depend on the electricity supplier and export tariff chosen.

If you want to apply for an SEG tariff, check the eligibility requirements with the electricity supplier. Depending on the tariff, you may need evidence that the solar installation meets the required standards, as well as a suitable export meter.

Solar roof tiles are available from a number of manufacturers, although the products available in the UK can change over time. Before choosing a system, compare the efficiency, warranty, appearance, installation requirements and overall cost of different products.

Solar roof tiles generally cost more than conventional roof-mounted solar panels because they replace part of the roof covering and can involve more complex installation work. The final cost will depend on the size of the system, roof design, number of photovoltaic tiles required and whether the existing roof needs to be removed or altered.

To get an accurate price, compare quotes from local solar installers and check what is included in each quotation, including the tiles, inverter, installation, scaffolding, electrical work and any roof alterations required.
