well, be prepared for a shock! I would NOT recommend it!
And we sell them!.............if you fancy a bit of a read, I've pretty comprehensively explained the whys and wherefores here - this was written for a school, but I think you'll find it relevant!

On the other hand solar hot water heating panels can work fine on an E/W site - we just have a panel on each side,(one more than normal) a bit of extra piping and nifty switching - might send it up to all of £3,250 all-in!
Solar pv panels are a definite no no - cut and paste from same forum
"Splendid devices! - so simple to use, no moving parts, will last for 30 years or more
If they were cheap enough they have to be one of the very best forms of renewables, but they do at the moment have some very serious drawbacks - mostly that of cost! We are dependant on the global market, and in recent years, the price of panels has risen by some 30%, mostly due to the enormous demand from the German market, so to put in large arrays is "buying at the top of the market" -especially as there are big breakthroughs happening - my prediction is that we will see the prices plummet, probably in as soon as two years!
Based on those simple current facts, we cannot in all conscience suggest investment in large arrays - they are just not cost effective - the money will be far better spent on other technologies, or the PV part of any scheme put "on hold" until the prices drop!"
