As Happy As Silicon Basking in Photons
Written by Gavin Webber
Today I received our electricity bill for the quarter. I was pleasantly shocked to read that we were in CREDIT by A$27. And that was with an extremely cloudy three months.
Grid use = 1153 kWh. Average 12.1 kWh per day (not bad seeing the pool is about 5 kWh of the total)
Solar generation = 616 kwh. Average 6.2 kWh
Total cost of grid power incl service to property, metering charges and Green 100% Wind premium;
= 344.96 debit
Total credit from Net Feed-in Tariff (66c per kWh)
= 406.56 credit
Minus GST (tax) of $34.51 gives a grand total of;
= $27.09 credit
How is that for the hard benefits of Solar PV? I am hoping that this quarter will be even better. Not a cent to pay, and some to carry over into the next bill. Also by using Green 100% Wind from the grid, I avoided 1.579 tonnes of CO2e. One happy greening of gavin!
Finally some solar justice.
