For the stats geeks out there:
- from our 3kw system we exported 823 kWh of energy over the 94 day billing period - almost 9 per day. We got paid 60c per kWh for these.
- In that same period we generated 1922 kWh - or an average of 13 per day.
- Average daytime consumption is 4kWh - although this obviously varies.
- Our average daily buy-in from the grid was 7.6 kWh of premium (ie peak energy), and 6 kWh of super saver energy (hot water only, and not many baths were had in Oct-Jan, so you see why we need to get a new hot water service at some point!!)
- We're on a green power tariff, so some of our savings went on that extra cost, otherwise our bill would have been over 200 in credit.
- The minimum power produced by our panels since they were installed is 2kWh, and the maximum has been 16.
- By using the solar power during the day (av 4 kWh) we've saved $64, plus the power that the panels have generated has more than paid for the bill, with some credit to store over for winter, when there will be less sunshine.
- With savings and power generation payments, we've "paid off" about 5% of our outlay in this 3 month period.
How about you - do you have panels? How are they performing?
