Understood. I guess the point/question was, a 250W module with a 215W micro would "flat top" a heck of a lot of power where I live during the 6 months of winter we have. I've sized my system to account for increased production during this time. I guess it comes down to sizing. I find it hard to do the 250W to 215W systems seeing what my system does on a regular basis. I'd like to see hard numbers from an enphase system showing the gains on the knee of the curve compared to "flat topping".
