Evening all,
Here's an electricity load profile of my house today while I made a batch of bio from 180L of WVO.
I try to get the whole operation as close to the middle of the day as I can while my 1.5 kW solar PV system is doing it's best.
As you can see, the PV barely touches the sides when the 2.4 kW oil heater is on, but it covers a lot of the mixer, which I run for 90 minutes to do the reaction.
I think it costs about $0.35/litre to make including KOH and methanol, without the solar contribution.
Even though the PV system is relatively small, on average, I export 65% of the power it generates to the grid, even though I set my washing machine and dishwasher to go off either side of midday. Quite tough to utilise the full potential of your PV system without a battery.
