How much voltage must be generated in order for it to be useful at home? I can generate 24VAC. Can that be made useful in running a home?

That depends. How many amps? You can step it up with a transformer to 120 or 240v. Something tells me though that your 24v is gutless and your higher voltage is also going to be gutless.

What Strandor is talking about is wattage. You can convert 24VDC into AC. A 100W bulb would use 4 amps at 24VDC.

P (wattage) = I (Currect) X V (Voltage)

One common problem, conversion is never 100% efficient. So you have to also make up the losses during conversion.

I can run much of my home on 12V or 24V. It's set up that way in case of a power outtage. So, it is possible for 24V to be useful, you only need to find 12/24V appliances.

What is usefull V-- 24 solar panels are cranking out 293V DC, producing 4.2 Kw AC, or around 30kWh /day, which covers about 93% of electric load.
