2. Contaminant Protection Grease seals act as a first line of defense against contaminants. Dust, water, and debris can enter the bearing assembly and potentially lead to corrosion, pitting, and other forms of wear. By keeping these contaminants out, grease seals help maintain the integrity of the bearings.

Bifacial solar panels are also known for their enhanced durability. They typically come with a glass-on-glass design, which improves their resistance to environmental stressors such as hail, heavy winds, and extreme temperatures. This robust construction not only extends the lifespan of the panels—often exceeding 30 years—but also reduces the need for frequent maintenance and replacements. Consequently, investing in bifacial technology can lead to long-term savings for both residential and commercial energy users.
