[RE-wrenches] P1 micro performance

[Marco Mangelsdorf]

Check out the output of the modules below at 1PM on this Spring equinox for
this system here in Hilo, Hawaii.

 

These mods are SunPower 245s with the Power-One micro 250s.  Notice that the
AC outputs below are 223 watts and higher.

 

If we had installed Enphase M215s instead, the max output possible would be
~ 224 watts.

 

If there's clipping this early in the year, imagine the degree to which the
clipping will be increasing in the months to come as the solar insolation
increases.

 

And these mods were "only" 245s.  Enphase states that their M215s are fine
with modules up to 265 watts!  Imagine the amount of clipping taking place
when that kind of pairing takes place.
