SunTech solar panels test vs SCHOTT solar panels test

The consumer products test foundation Öko Test in conjunction with Photon examined all major panels available on the biggest solar power market.

Here is the score:

1. SCHOTT test result: "very good"

2. SunTech test result: "insufficient", later revised to "good".

The panels examined were SunTech STP205-18/Ud and SCHOTT POLY 220


Key findings will be explained in the coming blog post.
