If you need 9400 watts, 75 amps@ 240V, how many solar PV panels do you need?
75 amps @ 240VDC is 8,000 watts.
75 amps @ 240 volts equals 8 kW not 9.4 kW, so first you have to make up your mind how much you want. Then you have to decide what size of solar panel you want. If it helps, the 6 units on our roof, each approximately m square, are rated for 4 kW in bright sunshine.
