Most of registered solar installers want me to provide the model of my switchboard and meter. But the switchboard is locked and I dont have the key even though I'm the owner in one of the properties. And my neighbor is the renter and his landlord is not responsive at all.
My friend said the lock may be owned by the power suppliers. I'm wondering who I can contact regarding to this.
If your neighbour is correct and the lock is owned by your local energy distributor, you would need to contact them directly. You'll find them listed on the top of your AGL bill.
