A 270 watt panel is 64.88" × 38.98".
Your guesstimate of 10000 watts would require (10000 /270) 37.037 panels.
Doing the math (64.88 x 38.98 x 37), that is 93573 sq inches.
There are 144 sq inches in a sq ft, so that is (93573/144) 649 sq ft, or a
square
25ft x 25ft.

Now I'm not going to say it is impossible, but it is downright foolish....
