OT question for any posters or readers of the exchange on emergency 
power generators appended below:

I have a 10 kW standard residential solar photovoltaic system on my roof 
(no batteries or other added complexities).  I understand that if PG&E 
goes down it stops functioning, and more or less why this is.

Suppose I acquired a small generator and had professionals install the 
necessary (manual) switching to disconnect my house and the solar setup 
from PG&E and connect them to the generator.

Once this switch was thrown and the generator fired up, would the solar 
system function normally while the generator was running?  If so, what 
size generator might be required?
