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:
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.
