Systems are
distributors and installers of BP Solar
modules and associated products and are approved to
install systems under the government grant system.
Solar modules generate electricity
from the sun, i.e. they convert radiant energy into an electrical current.
This can then be used to charge
batteries, as in stand alone systems or by connecting a number of solar modules
as an array into a piece of equipment called an inverter, can be directly
connected into the mains electrical supply into the property.
Stand alone systems are generally
used for remote off grid properties, stables, holiday homes, beach huts etc. and
are not generally eligible for grants.
Grid connected systems are used in
properties that have a mains supply, but where the occupier wishes to contribute
to the battle against greenhouse gasses, by reducing the demand for electrical
energy produced by burning oil or coal.
During the hours of daylight the
solar array converts radiant energy into electrical energy which is passed to
the DC/AC inverter which creates 240V 50Hz and synchronises it with the mains
supply. This locally generated power is connected to the buildings consumer unit
and at times when power demand is modest, will supply power to the household
appliances. At times of greater demand or darkness the balance of power is drawn
from the grid.
Connection of such a system
requires approval from the local electricity supply company.
It should be noted that for
specific safety reasons the inverter automatically switches off if the mains
fails, this is not therefore a standby power system.
So what is the cost?
Systems are specific for each
application and costs will vary depending on size of array, location, etc. but
as a guide we offer the following:
A 1kWp system ( 1kWp stands for
one kilowatt peak power ) would comprise of the following:
12 off BP585 modules
1 off inverter
1 set of fixing brackets
1 lot of cable and sundries
1 system monitor
installation
If the system price is estimated at £8000.00 excluding VAT
A grant of £3000 per kWp is available and VAT
is only 5% on these systems, therefore the price that you pay will be
approximately £5400.00
Quotations are available on request.
So will I have free electricity?
As a rough guide, a PV array
mounted on a South facing roof which is not shaded, will generate approximately
120 units of electricity (kWh) per square metre per year.
A 1kWp system will have an area of
approximately 7 square meters, which would produce in the region of 800 kWh
per annum. ( units per annum)
It will also save in the region of
300kg of carbon dioxide going into the atmosphere per year.

in more detail please do not hesitate to call us.
