Our gas is around $140 per quarter hot water and cook top only

We have a medium sizes solar system and our bills for this year were

First quater $6.11 credit
Second $130
Third $650!!!!!
Fourth $72

Third quarter we used double the electricity but we had minimal sun and produced very little solar power and new baby meant the heater was on heaps more than normal and I was tired and it was wet so I used the dryer way too much.
