The idea of the electronics "wearing out"is a strange one. The inverters
are only at full capacity for a small amount of the time, at peak hours
which is only 2 to 4 hours a day, and only for part of that time if you
have clouds, and who doesn't?
Pushing them a little harder should not "wear them o

Just to add another $.02:
I agree with Mr. Berdner, wearing out the electronics is a significant cost in
that scenario.

I found the latest module "rightsizing" paper by Enphase pretty
interesting. It does stand to reason that there are a lot of hours in the
day where the inverter is producing less than rated power, so increasing
the module size makes sense. Obviously there is an optimum point in every
system where c
I see I forgot to mention that I have 210W modules on my home that were
producing the 215W to 223W.
William,
Your question is a good one. I've wanted to study this, but haven't had a
chance. I will look into it.

There are many reasons you might want to limit AC output. Say 120%buss bar
rule or some other rebate situation where its sized on AC, not DC size. So you
can maximize your daily production without going over the peak AC limit.

A while back (3 years)I installed a system (bid spec) for a school that used
215W RECs and D380s on a dual axis tracker. With the ability to monitor the
array, I see constant clipping. The modules will usually produce 199Ws
regularly. A few days ago we had temps of -34F and clear skies. My a
I have had a concern for a long time that as PV modules have gone up in
output that there is inevitably going to be more and more clipping taking
place as theyre paired with comparatively lower output inverters. In
effect, matching, say. a 260-watt module with a micro inverter with a max
output o
