Obviously a virtually free source of energy for a home has to be a good idea. However, whilst it may be good to incorporate into new buildings as a matter of course, it doesn't seem economical in an existing property.
We currently need our roof replacing, so I took a look at solar panel options:
1. To heat water only. As our boiler only heats the water we actually need, this is pointless.
2. Panels to actucally generate electricity. Sounds much more like it, doesn't it? Until you do the numbers. About £9,000 to fit, saving about £150pa on electricity in the English Midlands - where I live. Well, that equates to 53 years before it pays for itself. As I am 50 now, I will have long since subsided into a gibbering wreck smelling of urine before I get my money back.
Conclusion - keep my money and spend it on beer...
