Hi, A nice little video comparing mppt vs pwm with the batteries in bulk mode. mppt vs pwm

Price it is. What is strange here lately is that a few years ago it was the MPPT controller needed for 24v panels being so expensive that made 12v the way to go.
Prices in your area can be much different so YMMV (a lot!)
Last year and still on here is that the 24s are way cheaper than the 12s and you can get an MPPT controller (Eco-Worthy or Tracer) at little more than than a PWM controller. Here, eg, the 250w is the same price as the 150w

So I have a Hanwha 230w panel that cost $260 last year and a $102 Eco-W for $362. Two 12s would be about $450 and the controller $35 for $475. Going 24v and MPPT in this case was $113 cheaper.
