- electricity import cost - red column (albeit with the faulty meter)
- gas import cost - blue column
- total cost - column peak
- solar PV FiT income - green area
- balance between dual fuel cost & solar FiT income - black line
Basically the interesting part of this for me was to see that recently (21st July) we broke even for the year (2012) and so the amount we've spent on importing power (including the overcharge due to the faulty meter) plus the cost of buying gas, has been exceeded by what we've generated & been paid for by the FiT scheme.
Let's hope the green graph keeps rising with our FiT income long into the Autumn, before the winter comes and the gas use starts to rise again.
We are seeing a little more gas use now we're in Sept, though we haven't had central heating on it seems the hot water takes a little more warming now (average 3 then 4 units per day now, up from 2 all Summer).
