How long will the solar panels last and what happens if one is damaged? I am surprised some haven't been stolen and sold for scrap metal.
Politicians practising what they preach? It would unprettify their lovely building. If they did that, they would have no excuse to ban every other listed building from doing the same.
How long do they last? Current cells have a guaranteed life of 10 years with an expected degradation of 50% after 20 years with final failure of most of the cells in 40 years.
Why haven't they been stolen and sold for scrap? Well mainly because that apart from the tabbing wire and the aluminium frames, they are pretty worthless. Just glass and silicone cells. Much more value in going into a BT access point, grabbing a mess of cables, wrapping it round a towball and driving away. Faster too. Or stealing the power cables for the lights on the motorway, even more value. Millions of £ of copper are being stolen every day in this way. You could steal every solar panel in the country and the scrap value would not reach that.
It has been one of my bugbears since day 1 with "green" power. That the systems with the most support are those with the highest visibility but much lower delivery of power for the investment. I've been pretty consistent in stating that we need 3* current baseload power, all renewable, before we can even begin to talk about a green country with a green economy.
Just glad that someone else is pointing out the same inconsistency. Needless to say it was the Blair/Brown government which popularised these systems. Even if Cameron is too daft to realise the fact and change it.
I wonder if the minister is feeling the heat from the Greens as well as UKIP???
