The best photovoltaic solar panels
Thought I would share some information on what are rated as the best/most efficient panels available. Sanyo HIT Power N Series. The cells are hybrids of monocrystalline silicone, surrounded by ultr...

The question was all 24v MPPT, no 12v PWM. Battery voltage at 13 is not getting close to 36v or 39v so the " shrinking spread" as battery voltage rises is not a factor (or is it?)
The Vmp in this case is way out to the right at 30+ volts before amps fall off that cliff on the IV curve
However the MPPT does output "12v" --I am missing just how much that is wrt battery voltage? Is that the "spread?"
My question was to do with the MPPT output with 220w and either 36v or 39v panel. Is the MPPT's output different so the "12v" "spread" is different, so the amps are different? If so, which gets more amps to the battery bank at 13v--220w and 36v or 220w and 39v?
