sorry to butt in but althow an a class spark can install solar pv he is not qualified. australia have mcs acredition for solar pv and if your after getting a job doing it you will have to gain it. ive spoke to them and they said with uk c&g solar you could aplie for temp acredition getting 12 months to gain full acredition. all depends what you what to do when you get there,
in the uk c&g cost £600
in ozs same coarse cost $2000+
at the end of the day if you do the c&g here once youve done the ozy regs, you can aplie or temp mcs acredition and you are allowed to fit solar pv to the grid
and i done know about you but i wouldnt fit anything to the grid without a peice of paper and insurance to do so
