After having my solar/PW2 system commissioned in late May, I have just received my first electricity bill. Ten days of the quarter were non-solar when our inverter failed a month after installation (apparently a rare but known fault occurred). It was replaced swiftly under warranty! While running the risk of appearing to be bragging etc (sorry, I am just so excited by what solar and PW2 have done!), some noteworthy outcomes: We have gone from power hogs (daily usage above that of a 5-person household) to being less than a 1-person household Grid consumption down 82% compared to same time last year Our solar export was about half of our total grid consumption (and this was through winter!) and with 10 days of solar being out of action There was a delay in moving us from the general tariff to the time-of-use tariff. Our average daily cost reduced by about 75% going from the general tariff to the ToU tariff, due to our ability to shift the vast majority of our grid demand to offpeak times with the PW2. Only 5% of our grid demand has been at peak rates. It’s all been simply wonderful and liberating!!!
