Portable (suitcase) solar "install" question
I've gone back and forth on solar panels on the roof or portable. Well, due to a tight budget, portable is the only way I'm going to get solar for now and it makes sense for me to try it out 1st as we...

bologna, there is no need for a panel to operate between Vmp and Voc. With Vmp lowered by heat and low light, voltage drop can have the panel operate at lower current as the current drops radically at voltages over Vmp. PWM
If there is enough time then current taper can make up for voltage drop between the CC and batt but many a controller is limited to 2hrs which is not long enough if the charge rate is high enough and the sun goes down. In any event power is wasted due to voltage drop. This wasted power could have been used to charge the battery FULLER.
