About Double-sided high-efficiency solar panels
Solar power systems with double-sided (bifacial) solar panels — which collect sunlight from two sides instead of one — and single-axis tracking technology that tilts the panels so they can follow the sun are the most cost-effective to date, researchers report June 3rd in the journal Joule.

6 FAQs about [Double-sided high-efficiency solar panels]
Which solar power system is most cost effective?
Solar power systems with double-sided (bifacial) solar panels -- which collect sunlight from two sides instead of one -- and single-axis tracking technology that tilts the panels so they can follow the sun are the most cost effective to date, researchers report.
Can a double-sided solar panel generate electricity on both sides?
Researchers have invented a double-sided solar panel capable of generating electricity from the Sun’s energy on both sides.
Which bifacial solar panels are most efficient?
When it comes to bifacial solar panels, LG NeON2 BiFacial series offers high efficiency. Their panels have an average power of 5.6W per cell and 19.5% efficiency. While Jinko Solar's Tiger Bifacial series is known for its low cost, it has an average power of 3W per cell and is 20% efficient on average.
Which side of a solar panel is more efficient?
The front side of a solar panel typically has an efficiency of about 75-80 per cent. The back side, however, achieves an efficiency of about 91-93 per cent of the front, which offers up to 20 per cent more power overall when harvesting reflected sunlight.
Are double-sided solar panels better than single-axis trackers?
The model suggests that double-sided solar panels combined with single-axis tracking technology is most cost effective almost anywhere on the planet, although dual-axis trackers -- which follow the sun's path even more accurately but are more expensive than single-axis trackers -- are a more favorable substitute in latitudes near the poles.
