The most important thing, we have the strictest building regulations in the world. Not just in Australia, in the world. So, it comes down to if we're going to put solar on someone's roof we have to go through the same process. If you're going to build an extension, put a new veranda on we've got all our structural engineering in place, our certification, and at the end I hand over all the information. We had Cyclone Tracy which is 45 years ago that absolutely destroyed Darwin and that's why we have tough building regulations.

I always get this question. Oh, my sister has put a system on in Brisbane and only costs $6,000. Yes, if I lived in Brisbane, I could do the same but here in Darwin we've got building permits, and then we've got to put on all our feet the maximum of 400 apart so, that all adds up. Everything that we buy in Darwin has a freight component now. So, you add 5 cents per Watt on a panel to get it from Melbourne to Darwin. So, yes if I lived in Brisbane I could do the same price.

In the top end we've got the harshest climate that you could find anywhere probably in the world. From extreme heat in our buildup, humidity and then we curb the rain, and then the winds come along with that. So, with all that testing the way that it's certified, engineered, put on your roof, it's not going to blow off. So, at the end of the day, by paying that little bit extra there's a peace of mind in there. There's really a peace of mind. When it comes down to designing the system as is, what the people's needs are. So, mums and dads are off at work and feeds their fridge, the freezer, the fans or whatever they've still left running, and the excess goes out to the grid. Come home at night and they start drawing off what they put on during the day. So, Mr. Jakarna is the battery.
