Do watts and Amps increase when you ad panels in a parralel?

[CAP]

Its a simple question but I confused my myself. I have 9 ,solar panels on my Rv. each one is 18 volts
1.8 amp and 65 watt(approx). these are all in a parallel circuit. My question is what is the total amps and watts, thanks.

In parallel the Amps are added together. So 9 panels at 1.8 amps equals a total of 16.2 amps and at 18 volts

The total watts do not change based on parallel or series if the panels are all the same.

If you put all 9 in series you would add the voltage while the amps stay the same so 9 panels at 18 volts would equal 162 volts and at 1.8 amps

Simple answer is yes.

In parallel amps and watts add, voltage is unchanged.
In series voltage and watts add, current is unchanged

both great info from both of you, thanks

to clarify would the wattage for my circuit be approx 585(9x65) or is found another way

18v x 1.8A x 9 = 291.6 watts.

Datas on your first post are contradicting. You said you have 65 watt panels, but 18v and 1.8 amps does not equal to 65 watts.

What are the size of the cells in the panels (3in x 3in, or 3inx6in)?

[Sunking]

18v x 1.8A x 9 = 291.6 watts.

Good catch. If your panels are rated Vmp = 18 volts and Imp = 1.8, then Pmax = 18 volts x 1.8 amps = 32.4 watts. So if you have 9 panels then 9 x 32.4 watts = 291.6 watts.

To be a 65 watt panel for standard 12 volt battery system the Vmp would be around 18 volts, but the Imp would have to be 65 watts / 18 volts = 3.61 amps.
