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

Again, using higher voltage panels with a 12V pwm system is like putting salt water fish in a fresh water tank. It's ludicrous!
I just installed pwm solar for my son-in-law last year using two 140W panels for $318 (280W) and a $30, 30A pwm charge controller.
You can't come close to that price. Hell, your controller costs almost as much as the two 140W panels and the pwm controller.
As far as where the 5% comes from, you need to look at my earlier post to you. It's all spelled out there.

Your logic is nonsense. Not worth bring up. No one in their right mind will use a 72 cell panel in a 12V pwm system.
The same rules apply when comparing 400W 36 cell panels using pwm and 400W 72 cell panels using mppt. The difference in gain will be on average only 5%.
Where are you getting 5% from?
