Lindisfarne Castle on Holy Island has had solar panels fitted to generate electricity.

It's hoped the panels will generate just under 10,000 KWh of electricity every year, and provide the Castle's only source of power.

A monitor in the building's office will enable staff to see how much energy is being generated at any one time.

The installation design has taken into account the aesthetics and historical importance of the building by ensuring that there will be no weight or direct contact of the panels or frame on the roof itself...the installation of solar photovoltaic panels at Lindisfarne Castle is a great example of the successful use of new and green technologies on a heritage site.

The project to install the panels, which has taken two-and-a-half years, cost a total of £45,000. It's believed the project will payback within 16 years.
