Solar Joins 1,000 Year Old Gargoyles On Cathedral Roof

3 Nov

A cathedral in Gloucester is having a huge upgrade by installing solar panels to help cut its energy bills by up to 25 percent. Despite its 1,000 years of history, the cathedral was keen to embrace modern technology and is having 150 panels fitted on its roof.

The cathedral is based in southwest England and was built around the year 678 and is coronation site for King Henry III, the burial site of King Edward II and famously had a featuring role in three Harry Potter movies!

Mypower are in charge of the installation and say the cathedral will be the oldest in the UK and maybe even the world to have a “commercial size solar panel system on the roof.”

The great advantage of installing solar panels on cathedrals is that they are really tall. And the fact that they are surrounded by ornate buttresses and gargoyles and other fancy architecture means that the solar panels will mostly be hidden from the ground, meaning the cathedral gets to cut its energy costs by a quarter without really sacrificing its historic, architectural integrity. The panels will generate 25,000 kilowatts of energy a year, enough to power seven semi-detached homes for a year or make an impressive 250,000 cups of tea!

Mypower, the installation contractor on the project and the firms’ managing Partner Ben Harrison said they’ve had to work around twists and spots where the roof has sagged over time. He said they’ve worked closely with the cathedral’s structural engineers and architect to guarantee the work is completed properly. “At times it’s been extremely tight in terms of manoeuvrability around parts of the site, particularly when the work required us to work just inches away from centuries-old gargoyles, but we put strategies and measures in place to protect the building from any damage.”

A further advantage of building on cathedrals and older churches are that they were usually built pointing directly from east to west, leaving a huge area of south-facing roof that’s ideally situated for maximum solar gain.

The Church of England is running a Shrinking the Footprint campaign, and the solar array will help Gloucester Cathedral work towards the campaign’s goal of slashing carbon emissions “by 80 percent by 2050.” Given that the Church of England has declared climate change “a great demon”, and has even stripped itself from the dirtiest fossil fuels, I suspect we will see many more churches going solar as the costs come down.

Once finished, the 1,000 year old building will become the oldest cathedral in the UK, and possibly the world, to claim a commercial-sized solar panel PV system. The installation forms a key part of the £6 million Project Pilgrim scheme to make the cathedral sustainable for future generations.
