Hi everybody, this is my first real post so I hope I am posting in the right spot. I am putting together a off-the-grid solar system for my dad's RV. Currently I have 5 130 watt Sharp panels and a midnight solar classic 150. My problem is that in order to get good sun I have to put the panels 150 or 200 feet from the RV.
My local solar dealer says that in order to have it 150 ft I need 10 gauge wire if I hooked the 5 panels up in series but I would rather have it in the 200 ft spot because they would get more sun. I have tried to use some online wire calculators but have gotten stuck in some areas such as panel voltage(I thought that they were 12 volt panels but the panels say 17.4 volts, and if I hook them up in series are they 8 amps all together because of the higher voltage or are they 8x5 amps). Any help will be greatly appreciated. Thanks guys and have a great day.
So my question is what size wire would i need for 150 feet, and for 200 feet.
Btw. my solar panel specs. are.
(5) Sharp panels
Maximum power- 130 watt
Open circuit voltage- 21.9 volts
Short-Circuit current-8.2 Amps
Rated voltage-17.4 volts
Rated current-7.5 amps
