A. Watts = Volts x Amps

B. When the sun is hitting the surface of the panel:

If you put 2 17 volt, 7 amp panels in parallel, you get 17
volts and 14 amps output.

If you put the same 2 17 volt panels in series, you get 34
volts and 7 amps output.

If A. and B. are correct above, could some of you please answer the
following. If A. and B. aren't correct, then please set me straight
and then answer the 4 questions.

Question 1: Do you get the same wattage for each configuration?
(That's what I deduce from the above formula.)

Question 2: Besides increasing voltag and thus reducing wire size,
what is the advantage of putting panels in series over putting them
parallel?

Question 3: What is the advantage of putting panels in parallel over
putting them in series?

Question 4: When panels are put in series for a higher voltage, do you
need to double the amount of panels for the same load where the panels
are in parallel at a lower voltage?
