I've just completed a series of three articles for solarenergyexperts.co.uk, a really good website which has masses of information on solar energy and solar panels, to which I've just contributed I might add. The first article (links above) explores the subject of whether you should accept the various offers of free and low-cost solar panels offered by some solar panel installers or whether you should buy your own. The more favourable option seems to be that of buying your own as there is much more money to be made through the government's Feed-In Tariff's scheme.
The second article is more general, looking at the pro's and con's of installing solar panels. It's a very good idea, especially considering the savings to be made in the long term, but there are some things to be aware of.
Finally, a much more useful general article covering the do's and don't's of installing panels, as well as a short guide to how solar panels work and some useful links.
