Wiring your Solar Panels - Series or Parallel??
Which is right? What’s the difference? Well, first think of each of the solar panels as a battery. Wiring them in series (or end to end connecting one positive terminal to one negative terminal) will result in more voltage output. This is the same as putting AA batteries in your camera or flashlight. The amount of current stays the same as the rating of each battery but you add up the voltage of all batteries and that’s the output.
Wiring the panels in parallel (connecting all positive terminals together and all negative terminals together) will provide the same voltage output into your battery bank, but will increase the current to equal the sum of all the individual panels. This way you’re getting more ‘umph’ so to speak into your battery bank at a steady voltage. So the answer is…Parallel.
