After nearly five years in the making, Network Rail has today cut the ribbon on the world’s largest solar-powered bridge at Blackfriars Bridge across the River Thames.
As part of a project with solar installation firm Solarcentury, the roof of the bridge has been covered with 4,400 photovoltaic panels, providing up to half of the energy for London Blackfriars station.
First Capital Connect, which runs Blackfriars, expects the panels to cut the stations’ carbon emissions by an estimated 511 tonnes a year, further reducing the carbon footprint of its train routes to the south east of England.
“Electric trains are already the greenest form of public transport - this roof gives our passengers an even more sustainable journey,” said David Statham, managing director of First Capital Connect. “The distinctive roof has also turned our station into an iconic landmark visible for miles along the River Thames.”
The bridge will also act as a major advertisement for London’s efforts to become a sustainable city, with tourists and workers viewing the panels as they enter the capital.

The project was one of the most complex to date for Solarcentury, which installed the panels in a series of phases over the past two years, pausing to minimise the impact on the station during the 2012 Olympic Games.
Advertisement “We had different sections of roof available at different times to fit in with this complicated jigsaw of getting everything up and going,” explained Gavin Roberts, Solarcentury’s senior project manager, adding that the company had even considered shipping some of the components in via the Thames.
He added that as a city centre site Blackfriars presented a lot more challenges to a warehouse rooftop, such as transport restrictions and ensuring safety standards were followed while the station was still operating.
For such a large and complex project, Solarcentury said the key to success could be found in early planning and ensuring that the intergation of the panels is included during the design stage of the station’s wider upgrade project.
“Solar is often seen as an afterthought, coming in at the end of a project,” explained Suzanna Lashford, head of commercial sales for Solarcentury. "So having everything designed in as early as possible [meant that the project] would not only be quicker, but would also be cheaper.
“We did that very well at Blackfriars, but in future it is a must to ensure everything is kept to a cost minimum. Projects would then look much more viable for clients and we’ll see more of them cropping up.”
And while ministers warns of the risk of a potential backlash against “monster solar farms” on green belt land, Solarcentury maintains a solar bridge in the centre of London can have quite the opposite impact on the landscape and perception of renewable energy.
“The fact that it’s so visual is a real bonus,” said Lashford. “I think as astatement, London often tries to be a sustainable city and I think it’s great from that point of view.”
She now hopes the project will inspire more big infrastructure developers to embrace the benefits of renewable energy.
“Network Rail has invested funds into the project is a great sign for the solar industry,” she said. “They’re an old English institution and they’re looking to the future to make investments into non-core technologies for the business, and that’s a great statement that other large corporations in the country can start realising.”

Roy all public schools in California now mandate a 50% source of electric solar panels to supplement their electricity.
I see Canadians are also on board with this. It’s a start.
Considering Canada has the highest (50%) rate of higher education per population I’m not surprised.
That figure is by the way, the highest in the world.

Solar will never supply more than an insignificant part of the total needed.

Not with current or foreseeable tech available.

This is our home 8,000 watt solar system .

Nice Roy. I’m gonna guess you are completely off the grid. Heading that direction myself at the ranchero.

Larson you will never convince me anything of the sort. Best of luck with that hydrogen model of failure as well.
Your mentality needs a reset in reality.

Solar power accounted for less than 0.2 percent of energy generation in the United States in 2011. Solar power also accounted for 0.5 percent of global electricity demand in 2011. Total global solar energy generation capacity averaged 40 percent annual growth from 2000 (1.5 GW) to 2011 (69.8 GW).

Solar Energy Will Produce Less Than One Percent Of US Power In 2015

Yes but it is growing in spite of what Mr. Larson says .

Yes an in the 1850 we did not have much electic generation it to started small.

It’s growing only because of massive taxpayer funded subsidies and regulatory mandates.

Just like your system was Roy.
You never would have bought it except for the fact that your fellow countrymen paid you a massive subsidy and forced the power company to buy your excess at several times what they normally pay to produce the same kW.

Gee glad you are so smart they still are Installing many in Ontario .

Many more companies are doing installations every day.

Roy does not like it when I point out he is ripping off his fellow countryman. lol

Bunk and your know it They have a product to buy and many of us have installed Units .

It saves the Ontario tax payer many dollars .
I wonder why you continue to lie about my and others systems .
Michael is just showing how jealous he is about Ontario .

But I do Roy and you know it.

You sell your excess power back to the utility and several times what it normally cost them to produce the very same kW of power.

Your personal system was heavily subsidized or you never would have purchased it.

I am never jealous of those who basically “steal” from others.

It sure is easy to see why Mr. Larson has so few friends .
He thinks he is smarter then others re Canada’s Medical system .
.Re Global warming .re election of the USA President.
The list seems endless .

Roy gets a guaranteed rate for 20 years that is several times the going rate to produce electricity from conventional means.

He is under the much higher paying program that was in place when he built his subsidized system

He cannot deny it so he will lie about me.

He knows I know the truth.

Michael, Have to agree with you. I wish Roy was right as Solar does seem like the Nirvana, but even the post that opened this thread doesn’t tell the whole story (Never does really)

50% of Blackfriars use, is just for the station. Not the rail line itself which draws more current in 1 hour than Blackfriars does in a week.

On top of that, Blackfriars is only 1 of 368 Rail stations in London.

I think your 1% is a bit generous.

8,000 is the maximum power rating, which is what your panels would prduce under ideal conditions.

That’s the equivalent of 8kWh max output for when the sun is shining at a rate sufficient to be able to produce this power. In your area of Canada that averages out to around 4 hours a day (over a year)

The average consumption of a home is estimated to be around 900kWh per month. Divide that by 30 days in a month to gget the average daily useage. Thats around 30kWh per day.

At 4 hours a day, you would need a full 8kWh gneerated to live off grid. That’s every day.

The problem is, you need to use AC (Alternating Current) and your panels produce DC. Changing from DC to AC utilises about 20% of the energy produced. So now your 8,000 watts is down to 6,400 watts. (It’s called derating)

So you now have a 6.4 kWh A/C supply working an average of 4 hours a day, 365 days a year. This produces 9,344kWh is the year which equates to around 778kWh per month.

That leaves you 122kWh short. Admittedly it is likely to save you around $100 a month. But when the system costs around $13,500 it puts you, or the company that donates it to you 135 months in the hole.

At 7.5% APR, assuming you could get a loan that low, it would take you 27 years to break even.

Of course if you choose to live in the dark you can recover your costs a lot quicker.

Sorry Len you have it wrong .
The system is dong fine thank you and is almost paid for it self .

Three things you should know about the future of solar in Canada

Jul 17, 2015 By: Our Power
Last night, four experts in the field of solar energy in Canada were brought together by Emerging Leaders for Solar Energy and the Toronto Renewable Energy Group to answer the question:
Is solar a viable long-term energy source for Canada?
For the panel, Jake Sadikman, Dr. Jose Etcheverry, Ryan Magee, and Andrew Knapp, the answer was a resounding “yes!” Here are three themes from these experts to guide the future of solar (and other renewables) in Canada:
One: The RE-volution will be community-led

Broadly speaking, we need people involved and engaged as we head into the next phase of energy production and distribution in Canada. There are many aspects to this, starting with meaningful community engagement throughout project development. If Canada is committed to renewable energy, people must be involved in decision-making processes.
We must also discover the community benefits of renewable energy development, whether it is ownership through co-operative models, new infrastructure and income for municipalities, local job creation, or a combination of all of these and more.
Renewable energy also needs to align aesthetically with the communities where projects are built. Dr. Etcheverry used an example from Barcelona to describe how solar has been seamlessly integrated into the existing built form of one of the most historically beautiful places in Europe, making it welcome in public spaces.
Two: Renewable energy increasingly makes economic sense – but we can keep innovating

The costs of building and buying solar are coming down rapidly. According to the International Renewable Energy Agency, the levalized cost of solar PV was halved between 2010 and 2014. What’s more, renewable energy generally is competitive with traditional fuels in many markets, demonstrating that these technologies are viable from an environmental [FONT=Lato]and economic perspective.[/FONT]
At the same time, we can push for even greater efficiencies by continuing to innovate. This means innovation in technology, including energy storage in order to realize the full potential of solar. This also means streamlining processes – within Ontario, the process of building solar and connecting to the grid is done in dozens of ways across jurisdictions, not to mention each province’s independent approaches to energy. The economic case against renewables gets weaker every year, but there is also so much potential to explore new ideas and new ways of doing business.
Three: We have the tools, now we need the goal

There is no dearth of policy options to get us to 100% renewables. We even have a road map – in March, 2015, a group of scientists, engineers, and economists released a paper describing the steps Canada could take to achieve 100% renewable energy by 2035. With 62% of our energy already coming from renewable sources (mostly hydro), we are in a fortunate position to continue the transition that is already underway.

Well of course you would think that. You are being paid several times more per the kW you produce than what it coat to produce by conventional means.

In essence you are screwing your fellow countrymen.:frowning:
