which solar cell size is best. 3x6 o 6x6?

2) Panel Hi-Pot resistance. Hi-Pot is a electronics term, relating to high voltage insulation resistance / leakage. No real issues with a single 12V panel. But putting panels in parallel or series, increases the stress they see, and you can come home to a burning panel. As moisture builds, this gets worse!

can you pls give more explanation

I have found some documentation on this site:
I am really interested in this as I'm thinking of installing solar panels also.

Please do not post links to other sites particularly ones that compete with this one and are poorly written.

more amps = faster charging

.
the 2 different cells are almost about the same.

6x6 solar cell
Average Power (Watts): 4.1 Wp

²Average Current (Amps): 8 Imax

²Average Voltage (Volts): 0.5 Vmax
..........
3x6 solar cell
Average Power (Watts): 1.8 Wp

²Average Current (Amps):3.6 Imax

²Average Voltage (Volts): 0.5 Vmax
Now you would also have to look at the COST of Each different cell.
the 3x6 cells i get for about $0 .45 cents each. 6x6 are over $1.85
so im saving $0.95 cents to get about the same power.
Good luck and have fun,

Amperage is the volume, the amount of electrons going past a given point over a given period of time.
The voltage is the pressure pushing the electrons.

The higher your amperage the faster your batteries will charge, because there is a higher volume of electrons going to your batteries.
So I believe amps would be an important factor too.

The more amps gathered per square foot of space used is a factor I consider important, because space might be limited.

Now you are talking about cell and module efficiency. cell size has nothing to do with this. Conversion rates in W M² is the standard.
With a DIY panel you would be lucky to get 10-12% considering the quality of cells available to the DIY market and having little control over the manufacturing process as opposed to an automated factory will limit efficiency even further not to mention reliability and longevity.

The number of amps alone is not what you want to look at. You have to have volts too! The battery charging process will take watts into the Charge Controller to produce amps into the batteries if you use MPPT. Or the amps into the CC at the right voltage will produce the same number of amps out at battery voltage if you use a PWM CC.

We are still talking conversion rates and cell and module efficiency.
