The efficiency of a solar panel is not solely determined by its wattage. While a 400-watt panel can generate a significant amount of electricity, its performance is also influenced by factors such as temperature, orientation, and the angle of installation. Therefore, knowing the size of the panel helps users assess how many panels they can fit on their roof or in their yard, and how much energy they can potentially generate.

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.
