Why We Need To Rethink Solar!

[@radiobrojo]

Former monk here. The Benedictine rule calls for sustainable stewardship of the natural environment and many monasteries have rainwater collection, filtration, developed farming techniques, and many have added solar or even hydro if by a source for quite a while, good to see this growing.

[@klaxoncow]

That's good to hear.

[@t1n4444]

And why not? Religion doesn't mean stasis. If churches (other religious edifices are available) can have sound systems with radio mics for the vicar and lighting bars (I have installed LED lighting in several churches, interior and exterior) for visiting theatre groups/events. So why not solar panels? Just think of Jesus and his sunbeams ... entirely apposite.

If heritage buildings can achieve so much just imagine how much could be achieved by our industrial buildings if a small planning requirement was put in place.

[@Nikoo033]

There is at least 50GW of potential capacity of roof-top solar and car parks in the UK… that’s 16-25 nuclear power stations depending on the number of reactors. Of course, solar PV has a capacity factor of ~10% in the UK, but still, if you can store, that would still produce about 16% (46tWh) of the UK annual demand in electricity (275tWh).

Was in York last weekend and walked past the Minster. Great to see this action being taken. These building were started by people who would probably never see them finished in their lifetimes. We need that type of thinking for taking the hard decisions around tackling climate change in my opinion.

Absolutely brilliant. Well done, York and all the cathedrals on the church of England.

[@aaronvallejo8220]

Excellent work indeed! Imagine a 1,300 years old solar powered cathedral:) Here on the Canadian prairies we are preserving and renovating an "old" 1912 two story house with high insulation, triple pane windows, insulated doors and soon solar PV on the roof. This is the future for all our housing stocks well done!

[@danielcarroll3358]

I've done the same to a 1903 brown shingle in the San Francisco Bay area. Only need double pane windows and with the more moderate climate my solar produces thousands of kW-hr more than we need. All that insulation and heat pumps does the trick.

Well I'm blowed! I did not know so many of our churches and cathedrals had so much in the way of renewables. My local churches are in the Canterbury diocese and having recently been looking into infrared heating for our home, I was going to speak to our church wardens about considering it for our churches and church halls as all of our boilers are getting temperamental. Had no idea the church was ahead of the game with a ground source heat pump in our cathedral, amazing news. What a lovely evening, singing at a carol concert with the Salvation Army band at the church hall and now this wonderful news! Thanks everyone.👍

[@waqasahmed939]

It's probably worth letting your neighbours know beforehand, and ask them if they have any concerns You don't want people to object to what you plan to do so it's best to get neighbours on board. Mine isn't listed but I do have a flat roof. I've had structural engineer assessment and I've had planning permission sign off too in part because I actively notified all my neighbours via a letter in their postbox You need planning permission for flat roofs. It's worth perhaps mentioning that the solar panels will be black too, so they won't be bright blue. The colour doesn't bother me, but some people prefer black to blue

[@Umski]

We are custodians of a Grade 2* listed building and needed to pay for planning permission to install PV on a roof of a non-listed building just because it was in the curtilage - it was just a paper based exercise but a complete waste of time and money - the irony being that the listed building is a windmill, one of the earliest forms of renewable power 🙄🤦‍♂️

[@freeheeler09]

If we don’t use our precious, old buildings, then we let often them fall into disrepair. I worked for an agency that, in order to rigidly conserve some old buildings, mandated softwood siding and wood shingles, single pane windows, and similar sillyness. This in an area that got over 100 F in summer, had snow in winter, and was threatened by fire often in summer. Woodpeckers destroyed the siding within two years. Buildings have to evolve, yet we can still respect the original character.

[@spankeyfish]

lol, the Listed Building regs in the UK even mandate the construction techniques that can be used although they do allow fireproofing for thatch and other flammable ancient materials.

When you think about it - churches point east-west, therefore have large roofs that face south, ideal for solar. And are struggling because of diminishing flock, this could help keep vital parts of our material history open for all and help fight climate change. In addition, they have large roofs for water collection.

[@andyemmpee3037]

Very inspiring video thank you. Planning is key and with York it just shows what can be done with all these enormous old roofs on church's etc.

[@MrGreedyboyuk]

A real shame that the Church of England does not have a comprehensive plan to help roll this all out to rural Parishes. Many will struggle to afford this because they don't have the financial ability of the big cathedrals such as York and Canterbury. The "church" is wealthy but in effect it's either some relatively wealthy city cathedrals & some urban churches, the government arm which is the Church Commission. The CoE needs to have a renewables fund/grant system to deliver such renewables to rural churches. The CoE's expectation is there that rural churches comply with their 2030 deadline but don't seem to support what is required to make it happen. The cost savings are a given but the capital investment is the key problem, plus expert support to help Church Wardens with a complex evaluation& expensive installations.

[@Jaw0lf]

This is a fantastic story. "ASHP's don't work in old buildings".....well that one is absolutely blown out of the water! Hidden solar panels and on a grade 1 listed building. We need a change in planning to allow far more delicate upgrades to be done.

[@ericcolledge484]

How much extra heat will be generated by the solar panels compared to trad power supply?

[@pauln0371]

I've been saying for years now why don't the government put into law that all new builds both residential and commercial have to have solar panels of some sort. It would drastically reduce our reliance on Oil and Gas not to mention put energy back into the grid. People's bills would fall massively and it would help with what some people believe will be too much demand on the grid..No Brainer...

[@salibaba]

Because builders complain it will put them out of business, then hold out their hands for a subsidy

[@simhedgesrex7097]

Because they're too beholden to builders. Hopefully a Labour government wouldn't be so namby pamby - though I don't believe that the Labour Welsh Government or SNP Scottish Government have done this either (but I'm happy to be corrected if wrong). Unfortunately local councils don't have the power to insist in this kind of thing.

There already was a law in place that the conservative government tore up. A disgusting move like the post above said just pandering to building companies. It was going to eat into their profits a little bit.

[@stoo149]

Not sure of the legal requirement, but the big home builders are putting panels on most of their new builds in Scotland. I have huge issue though - in that there's zero effort being put into how to maximise the potential. Most homes have at most 3 panels, regardless of the size or shape of the roof (although most are so poorly designed for solar that it's difficult to put many more on there anyway). There's actually a block of flat's near me that were built recently with the advertising suggesting '100% solar power'. Turns out, all of the panels have been fitted to the NORTH facing roof and are permanently in shadow. The south facing roof, which does benefit from the sun has no panels. . . .

[@salibaba]

@@stoo149 I’ve seen that once or twice too. They’re just putting on to tick a box for the planning. God knows if they even install an inverter for them, maybe added cost to give as an option to buyers.

I was in Germany earlier this year and the size of some solar arrays on farm buildings and warehouses was bonkers!

I feel like the need comes in several parts: 1. They want to, well, reduce their own bills 2. The organisation (city/CoE) made a commitment, and it's a good look when they're following through on it directly, rather than shifting it elsewhere 3. Using famous sites creates a great deal more awareness, which will hopefully push for more projects both similar and also less ambitious in scope - such as on industrial units that you mention

I know there are ideas for solar roof tiles but I can't understand why the standard solar panels can't be designed to basically double up as a roofing system in the way they fit together. (if you can see what I am getting at) I can't see why it would be technically hard to design or be expensive to do it at the manufacturing stage.

[@judebrown4103]

I believe they do make some that sit flush with the rest of the roof tiles. I've heard they have a tendency to overheat in high summer and actually become less efficient if it's too hot. I'm no expert and may have got the wrong end of the stick though, so do research, won't you?!

[@johnodell5310]

Take a look at the Tesla roof tiles and others of the same design that connect together just by being laid on top of the adjacent tile. Gold plated contacts ensure reliable connection. They look like a conventional tiled or slate roof when completed.

[@Bettys_Eldest]

@@judebrown4103 all solar panels become less efficient when too hot, which is not an excuse not to fit them. In some very hot locations it is beneficial to use some of the generated power to run fans across the panels reducing the temperature with a net increase in power generated.

[@judebrown4103]

​@@Bettys_Eldestoh no, I wasn't for a moment suggesting one shouldn't fit solar PV. I was merely attempting to answer the question: why are panels fixed onto the roof with a gap underneath and not often fixed flush with the rest of the roof covering? I was suggesting that they are more efficient with an air gap to provide cooling. Interesting about fitting a cooling fan though...👍

[@peterjol]

@@judebrown4103 what I am trying to suggest is that with a little bit of design the solar panels could easily BE the roof ..not on the top of the roof..there would then be the air of the loft space underneath. (although I suppose it wouldn't be circulating air so they wouldn't get quite as well cooled by that and it might make loft spaces too hot)

[@pinkelephants1421]

This is the kind of thing that should be possible for most, perhaps all, listed heritage buildings, that I've been insisting on for YEARS.

£30,000 per day for heating and lighting sounds too high to be correct. Are you sure that this is correct? Also, while hard to compare by using number of panels, it seems strange that 200 panels would reduce York's consumption by 40% when my 46 panels (15.325 kW) in a sunnier latitude would not produce a quarter of the energy that York's panels supposedly do. I wonder if someone has made a mistake regarding York's consumption.

Wind turbines aren’t an option for many. Most of the population either lives in cities or urban environments. Planning restrictions mean you cannot erect turbines near habitable properties, plus you need properly exposed locations and a good height to make it worthwhile. You can stick small turbines on the side of houses but they don’t get much more than a good couple of hundred watts of generation if the wind is blowy.
