We just came down the refrigerator chimney on the roof so no extra holes were needed on the roof. We used the space behind the refrigerator as a duct space to take the wires whee we needed them. We put the solar isolation switch inside that space beside the refrigerator access hatch.
We put 8 100 watt AM Solar panels on the roof and the WiFi Ranger and Verizon extern ion antenna for their modem on the tool of the refrigerator chimney.
