Bifacial modules produce solar power from both sides of the panel. This is based on something called the ‘albedo’ effect, where a light coloured floor or ground reflects enough light to generate electricity through the reverse side of the bi-facial solar panel. Thus, these panels can generate more power than other panels in the right conditions.

Mono-perc solar panels have a passivated emitter & and rear cell and produce from a single side.

Even for the same wattage (Wp), TOPCon-based solar panels can perform better (or proudce more solar power). This is due to the better efficient solar cells used and lower degradation levels. On an average it is said that TOPCon-based modules can produce 5% extra generation than mono-perc based solar modules.
