The cold winter meant we needed a heat pump and this put up our electricity bill to $450 for the first time for two years. Financially it is better to not pay for electricity if you have money in the bank earning interest. To earn $450 in interest at 3% requires $15,000 of capital and the extra panels only cost $3000.
By not having the annual expenditure of $450 it is equivalent to earning 15% on the money invested in the panels. I'm just waiting for the price of second hand electric cars to come down and I will be doing the same thing with my petrol bill.
