Sunpower is in the process of releasing their own microinverter if I recall
– maybe another option.

It is true that their performance is better. Just have a look at the
temperature
Howie is absolutely right. Strings with different orientations on the same
MPPT are not a problem. Modules with different orientations on the same
string is a big problem. Search the archives here and you'll find a good
discussion on this. The short version is that voltage is a function of
temp,
Wrenches,
I am talking with a potential client about a roof mounted PV array. The
client has a reasonably large south facing roof, but it is broken up by
a large (18' W x 16' H) shed dormer. The roof is 10:12 and the dormer is
6:12. I designed a layout that gave the dormer some room to avoid
Hiltonthere are a couple ways to approach this.There are some
string inverters with multiple MPPT inputseach different slope of roof
would be installed into its own input.the other way is to use micro
inverters or other individual module optimizersin which case you are
My understanding is that if all the modules in a string have the same tilt
and azimuth, the MPPT hit is nominal with 2 strings of differing angles.
Particularly, if they have the same azimuth, their voltages will be close
to identical almost regardless of pitch, and therefore the current from

I second the microinverter option in this scenario. Since you are up against
a SunPower dealer, use the microinverter features to your advantage since
the E20 series module is not compatible.
I probably shouldn't be saying
