Nerum Bonesetter, We are really pleased with your honest recommendations. Before solar power system: Contact Energy bill was $ 300 to 380 in winter and $ 280 to 240 in summer. Fixed charge $ 61 and kwh charge of 18 cents After Solar power system: Winter bill is down to about $ 100. Summers come to about $ 20 and sometimes even Zero. Genesis energy night 15 cents per kwh Day 31 cents per kwh Export credit 12 cents per kwh Low EV  Daily fixed charge of 60 cents or $ 18 per month. Hi Nerum, it has been about 10 months since you installed the 11 panel Fronius solar system at our place. We are seeing a marked difference in our energy costs. Before we used to pay about $ 3000 per year for energy and now I estimate our cost to come under a $ 1000 (mostly because of the fixed line charges). As per Fronius solar app: My peak production was more than 800 kwh in January with consumption coming in at 184 kwh for the month. In May the production was down to 453 kwh and consumption at 166 kwh. So I am producing 3 times as much as I need in winter and more than 4 times in summer. Also since I also bought a electric vehicle, I am saving about $ 100 on petrol per week or about $ 5000 for the year. I have to travel 70 km a day to work from west Auckland to Manukau - about 5 times a week. I usually end up running 25000 km on the clock every year. These are approximate figures as per my knowledge. So I believe by September, when I complete 1 year of solar system install, I would have saved $ 7000 ($ 2000 on power and $ 5000 on petrol). Off course, had it not been for the newly introduced RUC charges, which should come to about $ 1750 a year for 25000 km, I would have paid off my solar power system in 2 years. It should take a few extra months now. But anyway, just updating you on the performance and economics of owning a solar power system. Thanks for persuading me into taking this decision.
