ACTIVE SOLAR WATER HEATING
This uses panels, called collectors, usually located on the roof of a building,
to trap and store heat from the sun through water storage systems. These collectors
heat up a liquid which circulates a water tank. This heat is used to heat water
in domestic dwellings and also industrial and commercial buildings.
- Possible savings of up to £150 per year
for a typical home
- Capital is
recouped in around 15 years, compared to 20-25 years for double- glazing.
energy costs for the future as fossil fuels become more expensive.
- Saves between
300kg and 2 tonnes of CO2 per year depending on which fossil fuel is
being displaced, i.e. gas, oil or coal.
“With over 50,000 solar water
heating systems installed in the UK , the concept is fast becoming
a prevalent method of sustainable energy.”
BENEFITS FOR DEVELOPERS – Developers would benefit by using
PV in their new builds, as it is a growing market and they must remain competitive
in such a dynamic environment. Their properties could sell better, at a higher
price and they would be enhancing their businesses ‘green credentials'.
BENEFITS FOR FARMERS – The use of Photovoltaics reduces electricity
bills and enable the farmer to produce their own electricity and even get paid
to provide electricity to the grid.
In addition to this, threats of terrorist attacks have resulted in oil sources
becoming extremely unreliable.
A commercially installed system ranges from approximately £2500 to £4500 ,
dependent on the size of the system. A typical installation in the UK required
a PV panel of 3m 2 to 4m 2 with a storage tank of 150-200 litres. However,
the size of the system will depend on the amount of hot water used, which can
be calculated using specialist software.
If any changes are being made to a property, you
must apply to the local council for approval. Planning permission may be required
depending on individual specification. Diversitec

Currently there is substantial funding available for
renewable energy installations, as a drive to increase the use of such technologies. Diversitec
can help you to access this funding and give you the best possible opportunity
for such assistance.
This method of renewable energy involves the conversion
of energy from the sun into electricity by means of “semiconductors”, which
are non-metallic materials such as silicon, which generates electricity when
exposed to light.
The introduction and increase of the ‘climate
change levy' within
our electricity bills will soon result in people trying to source cheaper,
So, as the scale of production increases then prices
will fall and PV will soon have a higher position than grid electricity
Prices vary, depending on the type and size of the system.
Integration during a new build is usually substantially cheaper than installation
into an existing property, as the PV panels replace other building materials.
the past two decades the price of installation has reduced and the cost of
a domestic system is now between £5000 to £7000
per kWp installed. (It takes 5 kWp to meet a household's annual electricity
INTO THE FUTURE
Renewable energy offers stability and ‘peace
of mind' and it is time to move into the future and utilise this opportunity. Development companies must keep ahead and use such opportunities
to improve their businesses by integrating technologies like solar power into
their new developments. The United Kingdom is a major exporter of PV technology
to areas of the world in which grid electricity is remote or expensive.
FACT: Modern PV cells do not require direct sunlight ,
so normal daylight is sufficient to produce electricity.
A grant of between 40%
and 60% of the total installation is available for Commercial organisations,
small businesses, homeowners, public sector organisations and voluntary/community
