Bifacial solar panels, the reversible fashion accessory of the solar industry, are double-sided panels that absorb solar energy from both sides. Tests by solar manufacturers have found these panels can generate 11% to 23% more energy than their monofacial or single-sided counterparts.
However, just because bifacial solar panels provide greater utility doesn't mean you can contact your local installer and have them mount one on your roof. These panels function best when installed at ground level, absorbing sunlight reflected off the Earth's surface. While an 11% to 23% increase in electricity output may seem small, this incremental gain can significantly accumulate over time.
