Na der ist halt noch richtig neu....
Sind wohl PERC Zellen drin - bei der Leistung....
Hi,
I registered after finding your post on this forum.
I'm looking into these panels too as they seem to have an exceptionally good price.
However, lack of information and especially the "-3% - 0" tolerance mentioned on the website of alma-solar is not a good sign, I think.
3 percent of 300 is 9, so basically they might be 291 wp panels...
their 280 wp panels have a positive tolerance of 5 so the best might be 294 wp...
I asked them about the fact that their text mentions "0-5% positive tolerance", I'll post again when I get answer.
Wir nehmen nur wenige Sekunden auf diese Frage zu beantworten. Wir haben diese Solarzellen bestellt, aber in diesem Moment, es ist nicht in ihrem Datenblatt.
BISOL hergestellt gerade für ALMA SOLAR diese Solar-300W-Panels. In diesem Moment ist vorbei BISOL das Zertifikat für 300W. Die IEC-Zertifikat wird auf 295W begrenzt. Es ist, warum wir nicht mit positiven Toleranz zu verkaufen autorisiert. Aber diese sind Solarmodule bei 300W.
well that's a coincidence... 
Thanks for the update.
You aren't the only one who asked us it.
As Alma Solar is the only to propose this solar panel at this power, we can understand that customers need a explication.
We will receive a full truck second week of April.
Don't hesitate to contact us by your forum or directly from our webshop.
I have six of these panels on my roof since last week. Seem to be working fine, although I can't really say anything about yield as the weather hasn't been very sunny...
