Update on our Energy Balance for the 12 months of 2020.
We buy gas and electricity from Scottish Power and have a 4 Kwh PV array installed in November 2011, plus a 4kw battery storage installed in late 2019.
The FIT "paid" for the capital cost of the PV panels at the end of 2019.
This means that the year of 2020 is the first "real world" test.
Electricity we used 6641 Kwh which cost £1024. We have LED bulbs almost everywhere, but otherwise are not excessively frugal..with an AGA TC we couldn't be.
We generated 3935 Kwh and were paid £2331.96 (tax free!) FIT income.
Gas we used 14819 Kwh which cost £594.23: since we had the device to switch any unconsumed electricity, in excess of charging the battery, to heating hot water our gas consumption has fallen by 10%, I estimate. We also had an air source heat pump installed in late 2019, it functions as a A/C unit in the summer, a heater in the winter. I think this has saved both gas, at the cost of a small amount of electricity.
So our total energy coat was £1618.23, so offsetting the FIT income our energy is free with a Tax free profit of £713.73 a year.
I think that I need to look at adding to the "power wall", so we store more of the electricity we generate, but can't use that day.
Overall, a good result, I think!
Has anyone else analysed their 2020 Energy Balance?
