this has nothing to do with maths, i know what my bills were because i was paying them, $1000 per year, plus the $500 i didnt have to pay in repairs to replace the barge fuse that was torn off from the front of my house by a truck collecting the sagging street cable that ausgrid failed to repair, by holding out for six months i was able to drag ausgrid to the ombudsman who held them to account. the solar setup enabled this. now into my second year another $500 saved thus far. this was about reliable power supply for me, no more power outages when storms pass. i didnt keep my old bills so i dont know how much power i was using , i think it was about 26c/kwh plus about $320 in network fees per year. the 26c/kwh has gone up since i was a customer
my cheapo off grid system

It's great that your bill went down. But from what you have posted, it's not (primarily) due to your solar power system.

To be fair... compared to a parallel universe where almac remained on the grid, his system really is paying for itself, even if most of the savings is reduced consumption. In the same way that I know I *could* lose weight if I put my mind to it, whatever health complication that occurs that finally convinces me to do it will get the credit.CS6P-260P/SE3000 - http://tiny.cc/ed5ozxComment

yes my consumption is less, on the grid i was using electrically heated hot water. now i am using gas hot water so that is some of the missing power from the equation. im using a gas water heater at the source shower, runs off a 9kg gas bottle , its only $10 to gas up and lasts 2-3 months, also using more efficient refrigeration, chest freezer instead of a vertical fridge.Comment

To be fair you should determine what you now use in watt hours compared to what your solar / battery system can produce to see if you are spending less using solar then connected to the grid. All other costs (grid reconnection and power for the water heater) should be removed from your comparison.Comment

Happy xmas and summer/winter solstice. this system is still serving me well coming up to 2 years soon. the batteries are still good. had bought a cheap gen last winter but never needed it. still using the 2 x 100AH deep cycle batteries , the 2 sets of car batteries i sometimes use for backup if the deep cycle get depleted on a cloudy day, the car batteries are about 60AH. Runs a chest freezer, washing machine,coffee machine, tv, laptops, microwave, lights and more. might get a 400AH battery bank before next winter would make things easier
