I reckon it can be done for ~£150 for a controller that can control up to 16 * 1 or 1/2 kw inverters which should cost about £20 per KvaAnd then get it certified to be legally connected - that's when it'll become expensive and what I suspect is where most of the money goes on commercial ones )-:There are "only" 26 million homes in the UK. To get a million of those - 4% - to generate some of their own electricity is a huge undertaking.This is the competition: http://www.navitron.org.uk/product.php?proID=106 good luck!However I'm not sure self-generated electrickery is that viable right now - PV panels are still expensive, wind is a bit hit & miss for most people and water only suitable for the very few.If my Sushi Bar generator works you're looking at less than 2p per unit. When its this cheap you're silly not to.My solar (water) stuff cost me £2K for a DIY installation and I'm looking to halve my gas bill which will give payback in 2 years or so.Care to elaborate?
I posted this a while ago http://www.100297.itsosbroadband.co.uk/inverter/Sushi%20Bar%20Generator.htmlI haven't the time to build it myself - I thought I could get an old go-cart and hack that but they don't seem to make them any more and no-one I can find sells the bearings I would use. Several people have said it wont work but no-one has come up with a valid reason yet - other than they make much more expensive turbines..
