Solar powered street lighting go
on trial in Stornoway, Western Isles
Solar powered street lighting may become a common
sight around the Western Isles if a pilot scheme
for the first ever grid-tied lighting system in
the UK proves to be a success.
Comhairle nan Eilean Siar (Western Isles Council)
is piloting two solar powered street lamps to see
if they can benefit from the sustainable technology
provided by South Wales-based solar power experts,
SolarGen Solutions.
One of the solar powered street lamps will be a
stand alone light where rays from the sun will generate
the power that the light requires, and will be located
in the Lochs area of Lewis.
The second street lamp will be located in Stornoway
town centre and will be a pilot grid-tied system
in addition to the existing lighting units which
are currently connected to the grid supply system.
With sustainable development and energy saving
high on the local and global agenda, Lochs Councillor
Donald M Mackay, Comhairle nan Eilean Siars
renewable energy spokesman, said that the future
for the Western Isles was very much in energy saving
and renewable energy.
These solar powered lights complement the
renewable energy and energy efficiency initiatives
taking place in the Western Isles and our aspirations
for the Islands to be a centre of green energy.
I believe using solar power is a definite step in
the right direction for the Western Isles.
Not only are they environmentally friendly
but they are also a cost-effective solution to the
growing cost of public lighting.
SolarGen Solutions, based in Newport, South Wales,
has also designed and manufactured solar powered
bus stop lighting, footpath lighting, road signage
lighting and school traffic systems for local authorities
across the UK.
Ken Bird, Managing Director of SolarGen Solutions,
said, This is the very first grid-tied system
in the UK and is unique to SolarGen Solutions. The
UK could receive as much as two thirds of its total
energy requirement from solar power and our unique
solar solutions can be applied to just about every
public lighting requirement.
These lighting lamps can be stand alone or
grid tied, feeding the spare power back into the
National Grid. The Grid Tied solutions act as mini
generating stations and reduce the money spent on
electricity bills greatly, whilst our stand alone
units cater for communities where the cost of caballing
has to date prohibited councils to provide lighting.
The units have also proved to be very durable,
require very little maintenance and therefore are
a very cost-effective, and in many cases cost negative
solution.
We are already providing a number of local
authorities across the UK with solar powered lighting
and traffic warning systems with many more are currently
on trial, Ken added.
Another environmental feature of the solar powered
streetlight is that each unit represents an annual
saving of 1.5 tonnes of harmful CO2 going into the
atmosphere.

Note to Editors: Grid Tied Systems
A Grid Tied system is where a solar photovoltaic
module generates electricity and injects it into
the local grid system rather than into a storage
battery or batteries.
The distinct advantage of using a Grid Tied system
is the fact that the electricity Generated by the
system is produced during the daytime when demand
is at its peak, whereas the system lighting loads
are during the night at off peak times.
An additional advantage is that no batteries are
required for storing the generated electricity.
Consequently, the sizing of a suitable photovoltaic
module necessary to energise the Proposed 11watt
Compact or 18watt Sox-E lamps in a grid tied system
is considerably smaller, its annual output only
needs to meet the annual load because
The grid acts as an annual intermediary storage
and smoothing device.
