Yes Enphase cost more.
Standard warranty on string is 10 years Enphase is 25.
Add in the cost of an inverter replacement down the road and reduce the added cost of Enphase by the 30% federal credit and Enphase wins.
Yes harvest will be higher on Enphase. This is due to a higher derate as module mismatch etc are eliminated.
When I say Enphase Iean micros in general.
Who will be around in 25 years is anyone's guess.

Microinverters risk sun damage?

Very true. If on the moon, I am sure they would work well during the hot daytime except for sun-rise when they are 150*F below zero and voltage spikes.
Someday, someone will build a high voltage micro to support up to 350W modules. As efficiencies grow, it'll be necessary.
But many people who buy micros really don't need them - they like the individuality of looking at per-module graphs and finding a module is off by a watt or three. With clear sky an no shading, I don't see why micros would be chosen over a good string inverter.
Someone (not here) with micros was touting that they got much better output on cloudy days due to the micro inverters. I doubt that, however. Might have been told that by the Enphase rep. The cost of a micro-based system is usually more than one with good string inverters. I wonder if they recoup the extra costs with more output?Leave a comment:

The biggest reason is the high power like the 345's aren't compatible with micros that I have come across. The voltage on them is too highLeave a comment:

Hi all,
I was told by a sunpower sales agent that panels with microinverters may get sun damage in regions like south Texas (El Paso area) where the sun rays are so strong. He suggests a string system with the inverter in the shade for maximum efficiency. There is absolutely no shade on the south face of our roof, so that is not an issue. What do you think?
I am considering a non-sunpower system that uses microinverters, which is a bit less expensive.
Thanks!Leave a comment:

The sales agent was a retard? Did he drool and slobber?
You do not want to deal with that type - he is either stupid or trying to hustle you.Leave a comment:
