The certification may be expensive but I would imagine that with sales potential in the UK alone of a million units it should work out pretty cheap per item.On Mon, 7 Sep 2009, tom wrote:How about an Open Inverter? Put together a modular design for (eventually) grid connected inverter.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 )-:
If my Sushi Bar generator works you're looking at less than 2p per unit. When its this cheap you're silly not to.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.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.
