Solar Tiles - Solar Roof Tiles - Photovoltaics
Solar tiles operate on the same principle as solar PV panels. The advantage of Solar tiles is that they are
manufactured to the same modular size as large format roof tiles. They can be integrated into a
new roof at the time of construction or into an existing roof when the roof covering is being
Solar Tiles System
Solar tiles convert photons of light into electrical energy using a semi-conductor material.
When daylight shines onto a solar cell, electrons are released producing an electrical current. The volume
of solar electricity produced depends on the intensity of the light received by the solar cell.
Benefits of Solar Tiles
Solar tiles require only daylight, not sunlight, and are therefore capable of generating electricity
on a cloudy day. Solar tiles are unobtrusive and there is no heat, noise or radiation produced.
They can be installed on the roof of most homes and can be easily connected to the building’s
Each solar tile is a solar photovoltaic assembly with a solar module and a glass
laminate cover. Each module is supplied with electrical connectors that link it to adjacent
Fitting Solar Tiles
The installation must be carried out by a competent installer using standard roofing components. The roof installation process is
similar to that of normal roof tiles but the solar tiles must always be bordered by normal roofing tiles. As each base unit is
fixed the electric cables are fitted into the weatherproof connectors. When the complete array of
bases has been secured and the cable connections made then the laminate tops are fitted to each base.
Solar Tiles Stand-Alone System
A stand-alone solar tile system is useful where there is no connection to the local electricity
network or where the mains power supply is prone to interruptions. If the installation is for a home
that is not connected to the local electricity supply network, then the solar tiles can be configured
to directly charge a bank of batteries. The power flow from storage batteries is direct current (DC)
that can be converted to alternating current (AC) mains power by the installation of an inverter.
Solar Tiles Mains System
Energy supply companies are obliged to acquire a percentage of their energy from renewable sources, to help cut carbon dioxide emissions. By purchasing the surplus electricity from a Solar PV system, energy suppliers are able to fulfil this requirement. During daylight hours, the electricity generated by the Solar tiles will supply the home and any surplus will be sold to the nominated electricity supply provider through an approved import/export meter. During periods of high energy use in the home, or when the solar tiles are unproductive, electricity can be bought back from the network to guarantee continuity of supply.
Solar Tiles - Feed in Tariffs
Feed in Tariffs, or the Clean Energy Cashback, is a UK government sponsored incentive scheme designed to encourage the introduction of renewable energy sources. Under Clean Energy Cashback, an obligation is imposed on regional or national electricity utility companies to buy renewable energy electricity. By purchasing the surplus electricity from a solar tile system,
energy suppliers are able to fulfil this requirement.
Planning Consent for Solar Roof Tiles
National planning guidance urges local planners to take into consideration the
need to develop more renewable energy in their areas. Planning permission is usually only required
for listed buildings or buildings in conservation areas. In all circumstances it is advisable to discuss
the planning issues with the local authority before having a solar tiles system installed.
Before considering a system of renewable energy, it is
advisable to improve the energy efficiency of your house through improved insulation, draught proofing, low energy lights and heating controls
