What is a bifacial solar Panel?

Bifacial modules produce solar power from both sides of the panel (ऐसा सोलर पैनल, जो दोनों तरफ से बिजली बनता है).

Bifacial modules produce solar power from both sides of the panel (ऐसा सोलर पैनल, जो दोनों तरफ से बिजली बनता है). Whereas traditional opaque-back sheeted panels are mono-facial, bifacial modules expose both the front and backside of the solar cells. When bifacial modules are installed on a highly reflective surface (like a white TPO roof or on the ground with light-colored stones), some bifacial module manufacturers claim up to a 30% increase in production just from the extra power generated from the rear. The biggest advantage of a bifacial solar panel over a traditional solar module is the higher total energy generation. They either use dual-glass or clear back sheets.

Balance of system (BOS) costs are also reduced when more power can be generated from bifacial modules in a smaller array footprint.

What is Bifacial Cell?

Bifacial cell can generate electricity from both sides unlike conventional cell structure generating only from front side. Using bifacial cell, bifacial module can generate from front and rear side. With transparent back-sheet or glass, bifacial module can get sunlight from rear side instead of front side.

In India, however, majority of the solar panel installers do not have sophisticated mounting structure arrangement for bifacial solar panels and they use the same mounting structure that is used for normal panels and hence it fails to serve its purpose. This does not allow the panel to get sunlight on both the sides. Hence, it has failed in India. The mounting structure used for bifacial panels are more sophisticated and expensive and hence, not commonly used by the masses. It is more popular with the affluent businessmen and is seen atop restaurants, carports and coffee shops, etc. But now with the penetration of internet in india more and more user are searching for bifacial solar panels.

Benefits of Bifacial Solar Panel

Bifacial solar panels could be the future of the industry and more and more module manufacturers are moving towards Bifacial technology which help realize lower LCOE. It generates power from both sides. It has high power density, significant BOS savings, high energy yield, better low light performance and lower temperature coefficient. Bifacial solar panels are fastly gaining market share in India. It can practically increase the power output by upto 30% given your space restraint.

Some companies with bifacial modules currently on the INDIA market IN 2021 include TRINA, LONGI, JA, WAAREE, ADANI, JACKSON Solar.
