I want to use solar power for all my electric machines in the house. How do I hook it up so that the power comes straight out of the house wall outlet?

well Arthur, since you don't want to kill yourself or cause property damage, you hire a licensed electrician to do the work for you;-)

haha sometimes the simplest answers are the best.

Most solar systems can provide 120/240 single phase AC power to off-grid homes that have no electrical utility service. The size of a solar array and battery storage can limit your household usage of the power from the limited output of most PV solar system. In most cases off-grid homes will need a generator set to supply power for household use when appliance loads causes increased demand. Consult a licensed PV solar contractor or electrical contractor for more specific details.

I think we must first know where Arthur lives to pinpoint and recommend an energy system or installation crew.

I'm going to expand this discussion a bit and see what happens for the fun of it. Even if a prospective solar live outside the US most AC electrical voltages are simple 240V AC 50Htz. In the chance someone lives in a remote location away from electrical utility some manufactures sell appliances that can be run on 12, 24, or 48 volts DC. So there are option available for living off-grid power grids it is just a matter of your location and matching equipment to household appliances or power configuration.

Is it more efficient to produce and use dc power/dc appliances/lights off grid for a house than ac power appliances/lights?
