[QUOTE="chickens and wheat, post: 7413454, member: 1900"] 20% so far, winter only. Summer might change things? New panels had been up a couple of months before I got the export limiter off (waiting for transformer upgrade) and true comparisons could begin. Old panels washed before then. So they should all be a similar amount 'dirty' Transformer upgrade costs not included in payback. That spoils the figures somewhat, and solar wasn't the only reason to upgrade. Mains cabling for 100kw not included either as it was fortunately pre installed , not a small price to consider in some set ups. So it's not simple to calculate if solar is sensible or not. My gshp installer had a data logger on my supply for several months before installing that. Also we got hold of the half hourly data from npower after the gshp. All this data along with existing solar production data, showed solar was a good choice here. Having such research also helped negotiate good bank loan terms. [/QUOTE]
