[QUOTE="deanwilts, post: 531416, member: 34562"] Electrical wire has an internal resistance, which means electricity gets lost (as heat) and the longer the wire the greater the loss. So the general rule of thumb will always be keep wires as short as possible to avoid losses/waste. The higher the voltage in use, the lower the relative loss experienced, so for that reason if you have to run long wires from modules to inverters, you should increase the voltage on the strings. This can be done by creating strings made up of modules connected in series rather than in parallel. This is what I'm looking to do as I have a minimum of about 130m I need to run my cables (to back of a field). [/QUOTE]
