Sidmouth's largest provider of renewable technologies:
Photovoltaic Roof Systems
How does a photovoltaic system work?
PV modules are mounted
on an unshaded south facing (or near south facing) roof and use light from the
sun to generate electricity. The output from the modules is matched with your
household's electricity supply by an inverter.
Solar Thermal Roof Systems
Do I need to have a particular type of
roof for solar installation?
PV modules are mounted
on an unshaded south facing (or near south facing) roof and use light from the
sun to generate electricity. The output from the modules is matched with your
household's electricity supply by an inverter.
Features and Benefits:
> Sustainable energy. As solar energy harnesses the
energy from the sun, it produces none of the CO2 emissions of using fossil
fuels.
> Environmentally-friendly. Solar panels can be fully
recycled.
> Proven technology. Based on technology that has been
working for more than 20 years.
> Suitable for many locations. Can be installed on or in
a sloping roof, on flat roofs, or even on a wall or floor.
> You’re in control. The system includes a control,
which enables you to set the hot water temperature you require with ease.
> Easy to look after. Requires minimal maintenance and
is extremely robust.
How do I benefit from it?
There are several benefits of installing
a PV system on your property. Firstly, while you consume the electricity that
you generate you avoid the cost of purchasing that electricity from the grid.
As electricity prices are expected to rise sharply*1 over the
next few years, the annual value of these savings is likely to increase.
Secondly, under the
Feed-in Tariff, for a period of 25 years you are entitled to a payment from
your supplier for each unit of electricity that you generate, whether you use
it or not.
The amount you earn
depends on the type of system you have, and if you generate more electricity
than you need, the Feed-in Tariff provides for an additional sum for any
electricity exported.
Below is a table
showing the typical benefits of a 12 module (2.2kWp) system mounted at optimum
orientation and angle:
To put this into
context, consider that a typical 3 bedroom house with gas heating consumes
3300kWh*2 of electricity per year at a cost of around £400. The
total gas and electricity consumption of the house results in CO2 emissions
of around 5 tonnes.
