In this tutorial, we will show the basic wiring of photovoltaic panels in Series-Parallel connection to a single or multiple batteries, charge controller, AC and DC load via charge controller and an inverter. Current is the same while voltage is additive in series connection. This was because the lights were wired in a series. Circuitry diagrams are made up of two points: icons that represent the parts in the circuit, as well as lines that stand for the links in between them. However, if you were limited with your budget, or underestimated your future power needs when you installed your PV panels, you could consider adding more panels to your existing system. If I did get the 6B&s 12m wire if I added another 160w panel later (320w total) I calculate the voltage drop of both these panels as being: Vd=(12 * 17.8amps * 0.017) / 13.3 = 0.282v This is also less than the 2% voltage drop (0.36v) that was recommended so my calculations would say that 320w solar panel over 12m with 6B&S wire is ok. The use of microinverters or optimizers in the design of your solar system can help avoid inverter-size limitations that string inverters have.
