Beefheart - sorry this is a bit late and you may not pick up on this, but I was just looking online for something else and came across this thread.
In response to your point, please give me a call in the office and I'll sort you out with the password. All we need to confirm is your username for the website or if you don't have that we can search the register for you. On a side note, I recently (a month ago) revamped the spreadsheet to have the up to date FIT figures and added SAP CO2 calculations as well for your corporate/LA/HA clients. Although I would say if they really care about carbon, PV is not the best option interms of £/tonne saved!
So if you can log in to the EcoSkies.com website with your username and password, you'll find the 2011 spreadhseet.
In case your interested, A "G59 payback calculator" will be available soon to candidates that attend the Advanced PV Systems for G59 course.
