I know that's like asking how long a piece of string is. But there must be a typical or average figure per square metre of panel or something! I'm in the UK (same latitude as London).

The mean solar constant is 1300 Watts/square meter. That is in the upper atmosphere, so we maybe only get about a third of that on the ground. Now figure about 50% efficiency of the panels is a maximum (I would be surprised if we could even get half that much with anything but NASA solar panels), so I would guess that on the best day, in the best location, with the best equipment you might get 220 W/m^2. This will be even lower in UK.
Just a ballpark, upper limit guess.

"120-240 volts of AC power...for one cell under direct sunlight.
Now, big solar farms have FEILDS of thease things. You to the math. "

Someone else definitely needs to do the math. That many VAC from one cell? If that were true we wouldn't be using coal and oil anywhere in the world.
According to Backwoods Solar, there are about 36 CELLS in a MODULE. The Ultra SQ75P module produces 75 watts, 4.4 amps, and 17.0 volts. "Doing the math", it would take 8 modules or 28 of the afore mentioned "cells" to produce a full 120 volts. One of these supposed 120-240 volt cells actually produces less than a half volt.

Yah it totally depends on a lot of stuff, like if it is put in a good location where it can gather a lot of sun, and how big your panels are, etc. On average, one small panel can power a standard lightbulb.
However, there are these new tubes coming out on the market made by apricus that are way better than panels. They are rounded so they collect way more power, and you can actually touch them and they feel HOT!

Well, I don't know exact numbers, but I do know that it takes several door-sized panels to provide 100% electricity for a house here in the U.S.

Such solar power systems costs thousands of dollars.

At midday on a sunny day maximum photo voltaic panels will produce between 500 and 1000 milliwatts in line with sq. foot, a lot less for the duration of a few thing else of the day. masking an 1800 sq. foot terrace will produce sufficient capacity to run a coffeemaker.
