Re: Why you should install them
So the guarantee/warranty is for all parts for 20 years - you have to shop around to get this but it is available, and the panels are guaranteed to lose less than 0.25% efficiency over their 20 years.
And the money I used to buy them was being made redundant from RWE - so partly a way to pay less into their coffers and be paid by them for what I export (not the subsidy)
Not saying solar/wind is the answer just saying what has happened.
Yes homes use less energy during the day but industry uses more - shops, offices etc and they use much more than homes so generating in the day makes sense, the problem with wind is that there is more wind at night when there is lower demand.
Nuclear - may or may not be the answer the costs still don't stack up, they get huge subsidies to build the plants and the decommissioning, reprocessing costs are also high.
I'm not particularly pro or anti any of the technologies I just want cheap energy, after a personal investment that's what I have, if the subsidies weren't in force I would still have that, if I could have a small nuclear reactor for a similar cost great! However, burning up fuel from the ground in hundreds of years that takes millions to produce doesn't seem like a long term solution to anything
