I'd been researching for over a year. Knew I wanted to go mono panels this time. I've had a 45w poly system for years. It was great to put this system side by side on different RVs. I'm no engineer and it's like apples and oranges, but I love the new system, using just 1 panel 100w on cloudy day it was producing. After the sun set the poly system quit producing, but the new mono system kept going. Very easy install, I have it set up for boondocking in the desert. Would definitely recommend and will purchase again.
