In one example, I am looking at panels with 21 VOC and optimum 17.5 WV
Head-to-head, how much or how little will MPPT offer over PWM?
Discharged every day, at first the battery bank has zero chance of 100% replenishment with the first batch of panels.
There is a massive tradeoff comparing high voltage high wattage panels at low cost with an expensive MPPT -VERSUS- higher cost lower OCV panels using PWM. My interest is knowing the parameters of the "Value Bell Curve". How "much" is minimum? At what WATTAGE point of value does high OCV panels with MPPT offer a clear advantage?
Pardon my lameness. We engineers like to have things explained to us minus buzzwords, and emotional bias. I hope you understand. Thank you.
