We have panels:
Installed on a garage wall on the inside (other side of this lives the meter box). It was better than putting it on the inside of our side gate (as the gate swings inwards it would have been a gates distance from the meter box) and better than putting it above the meterbox (as it would be too high for me to reach/read). The installation inside the garage though is fairly low. I suppose low is better than high up...
And we even have our Gross meter:
We have been told with $0.60 feed in tariff we should be able to generate $1400 per annum. Which means a payback in less than 2 years.
