Voltage drop for 12, 24, 48 and 120 volt systems...

The two main things in picking wire size are: 1) don't exceed the maximum current carrying (ampacity) of the wire, and 2) don't have an excessive voltage drop along the wire.
I find these two tables helpful in a lot of cases to check for ampacity and for voltage drop.

 A good voltage drop calculator for any voltage DC or AC.
Also wire properties, resistance, ampacity table for copper wire.

 Very
handy wire size calculator.
It calculates the minimum wire size for 3% or less voltage drop.

PVWatts -- A Performance Calculator for Grid-Connected PV Systems
From NREL

This is a really useful tool. |
An easy calculator you can use to find out how
much power you will get from a PV installation in your area.
It calculates PV system performance based on hour by hour records for sun in
your area.Version 1 is very easy to use, and works worldwide.
Version 2 allows more detailed inputs, but seems rather complex and puzzling
at times to me. |
