Advice on proposed equipment

That means very little - small differences in orientation, tilt, cleanliness, local morning mist etc can tilt the scales one way or the other.

I agree Russ, but if I didn't mention it, someone would bring it up that I didn't give all the information, so in the interest of full disclosure. The difference between my west and south facing panels for the past 30 days is less than 1 watt hour so as you pointed out, no real difference. The real factor was the wattage difference between the Power-One inverter (250w rated) and the Enphase inverter (215w rated) along with the panel wattage matching.

I prefer the Power One Micros over the Enphase. One thing Enphase has done consistantly since day one is run in the red. Power One has actually turned a profit and they are sized more correctly for the 285w panels. Enphase typically will clip around 225w. Is a string inverter an option?

They do have string inverters available from 2kw to 6kw. Power-One is being acquired by ABB so they will even have more resources.
