We have a 49.5kW system installed ~late 2012, I believe we are being paid ~14p/kWh under the FIT.
We have more roof space, the solar units have dropped significantly in price as far as I understand, so we are considering to expand our PV to the rest of the roof.
Any suggestions on how to go about this? Our consumption is ~120,000 kWh/year, so not small. I firmly believe in trying to be as self sufficient as possible!
