Your original predictions when you quoted me were:-
3413 kWh produced = £1477.61
Exported to grid = £52.89
Electricity saving 1706 kWh = £221.81
The actual figures for the year were:-
3641.1 kWh produced = £1,627.32
Exported to grid = £57.66
Electricity saving 3640.8 kWh = £367.51
Therefore my:
Return on capital invested FIT only = 14.16%
Return on capital invested FIT + savings = 17.25%
