Bifacial solar panels are gaining popularity, but what makes them special? Bifacial panels capture sunlight from both sides, unlike traditional solar panels that only use one side. This unique feature allows them to generate more electricity, especially in areas with reflective surfaces like snow or water. They can be installed in various ways, including vertically or at an angle, making them versatile for different environments. Additionally, they tend to have a longer lifespan and better performance in low-light conditions. Curious about how these panels work and their benefits? Let's dive into 34 intriguing facts about bifacial solar panels!
What are Bifacial Solar Panels?
Bifacial solar panels are a type of photovoltaic technology that captures sunlight on both sides of the panel. This innovative design allows for increased energy production compared to traditional, single-sided solar panels. Let's dive into some fascinating facts about bifacial solar panels.
