Solar Update

Feb 27, 2012 22:55

Meanwhile, we've just got the sort of electricity bill I approve of - one where we don't have to pay anything.

This is our first bill to combine the solar panels with a smart meter, and also the most productive 3 month billing period of the year. Between having over half our usage at off-peak rates, only paying the supply charge to 1 meter (the old off-peak meter still previously got charged for even though it wasn't in use) and the higher solar feed-in tariff, we've come out with a credit.

Total usage: 941 kWh (519 off-peak, 135 shoulder rate) ($171.94 + $70.05 supply charge)
Total production: 529 kWh ($360)

Then there's some discount credits, GST added, and we end up being $102.95 in credit at the end of summer. It won't stay that way, but it's a nice buffer for the next bill.

As far as usage goes, we're registering well above last year because last year the meter was simply being wound back rather than generation being recorded separately. Compared to our first summer, we're using an average of 10.6 kWh a day instead of 13.6 kWh. So some improvement.
