The windshield of the module is frosted, with a minimal texture like BLACKSTAR, which allows for better absorption of light reflections. This is why this photovoltaic module is more efficient than its counterparts. The most efficient in terms of energy generation are solar modules with a white film. Just because such a module heats up less on a sunny day. And the less it heats up, the more electricity it produces. But solar modules with white film on the roof look worse than an all-black solar module, so those extra 5 watts from a solar module almost never outweigh the all-black look. So full black is the choice for most people.

All STANDARD solar modules are certified by TUV NORD laboratory and comply with IEC 61215:2016; IEC 61730:2016; IEC 62716:2013, IEC 61701:2011, ISO 9001:2015, ISO 14001:2015, ISO 45001:2018 standards.

SoliTek provides a 20-year product warranty for all STANDARD PV panels and an 84.8% percent performance guarantee after 25 years for half-cut modules.
