If you see dark spots on your panels, this could be a sign that your panels are undergoing delamination, and you should contact your installer for an inspection.
[pdf] The difference in color is due to the composition of the panels. Blue panels are made with monocrystalline silicon cells, while black panels use polycrystalline cells.
[pdf] An already high efficiency of 20.5% is further enhanced by bifacial design, which allows to harvest up to 25% more energy from the back side of the panel. The heat is also less of a threat with this module: with one. .
Careful module BOM selection and solar cell process optimization ensure solid PID. .
A 35 mm frame made from anodized aluminum alloy and 2 mm layer of protective tempered glass make this module resistant to the foulest of weather. These panels pa. .
Slow degradation over the next 3 decades is guaranteed by the manufacturer. The performance will decrease no more than 2% during the first year and then will be limited to 0.45%.
[pdf] These modules feature cutting-edge photovoltaic (PV) technology embedded in high-quality solar cells, making LONGi the winner of the Intersolar award in the photovoltaic category in 2021.
