diodes
How and where should i put diodes in my solar panels when i am building them? The panels i am building are going to be 12 volt 54 amp panels.

Why is a 54 amp solar panel unworkable?Comment
-
O wait sorry the system will produce close to 60 amps the panels will be at like 20 amps just depending on how i wire the cells together.Comment

When you figure out what size wire you need to connect each panel with, you will find that #10 ga wire is very expensive and unwieldy to work with. That's why arrays are often wired for higher voltage and lower amps, and a MPPT controller downconverts the power at the batteries, and you only have a few feet of 60a cable.Powerfab top of pole PV mount (2) | Listeroid 6/1 w/st5 gen head | XW6048 inverter/chgr | Iota 48V/15A charger | Morningstar 60A MPPT | 48V, 800A NiFe Battery (in series)| 15, Evergreen 205w "12V" PV array on pole | Midnight ePanel | Grundfos 10 SO5-9 with 3 wire Franklin Electric motor (1/2hp 240V 1ph ) on a timer for 3 hr noontime run - Runs off PV ||

what is a mppt controller?Comment

MPPT controllers, monitor the PV voltage, and apply a varying load, till the voltage sags, and then stays there, pulling the maximum amount of power from the array.
You can often get 20% more power from panels with these controllers than with the simple PWM styles, and they are needed for large arrays to reduce the copper required for high amps. They cost a bit more though.

ok so one more question if i buy a charge controller that is a 12 volt charge controller does your solar panles also have to be 12 volt panels as well or can you hook 24 volt panels to it? Basically what i am asking is does the voltage going into the charge contoller have to be 12 volts?Comment

You should feed the charge controller (any style) more then your battery voltage is. 12V battery , needs 17V PV. 24v needs 34V, 48V needs 65V (as a rough guideline)
Additionally, you can feed a MPPT Controller more voltage, and it will convert it to increased amps into the battery, at the proper voltage.Powerfab top of pole PV mount (2) | Listeroid 6/1 w/st5 gen head | XW6048 inverter/chgr | Iota 48V/15A charger | Morningstar 60A MPPT | 48V, 800A NiFe Battery (in series)| 15, Evergreen 205w "12V" PV array on pole | Midnight ePanel | Grundfos 10 SO5-9 with 3 wire Franklin Electric motor (1/2hp 240V 1ph ) on a timer for 3 hr noontime run - Runs off PV ||
