How do bifacial solar panels work?

Bifacial solar panels utilize the principle of photovoltaic (PV) effect to convert light into electricity. This is the same principle used in traditional solar panels, but bifacial panels take it a step further. They capture light on both sides of the panel using photovoltaic cells embedded in a transparent backsheet or dual-tempered glass.

Are bifacial solar panels better than traditional solar panels?

The majority of solar panels are monofacial. This means they have one photovoltaic side, which can absorb light from the sun and convert it into energy. Bifacial solar panels can absorb light on both sides and require less space. Because bifacial panels have more surface area to absorb sunlight, they are more efficient than traditional panels.

Can bifacial solar cells boost energy yield?

To boost energy yield, researchers and manufacturers are looking at bifacial solar cells, which are double-sided to capture light on both sides of a silicon solar module—they capture light reflected off the ground or roof where the panels are installed.

Can bifacial solar panels be mounted on a slanted roof?

Bifacial solar panels are not ideal for mounting on slanted rooftops. They do best hovering high over reflective surfaces like sand or snow. They can be mounted just like any other solar panel, but the more tilted they are, the more energy they deliver.

How do photovoltaic panels work?

To further increase the amount of light passing through, they use glass instead of metal frames or grid lines to hold them in place. The glass is tempered glass reduce scratching. Otherwise, they perform exactly as other photovoltaic (PV) panels work, using crystalline silicon to absorb sunlight and convert it into an electric current.

Why are bifacial solar panels so expensive?

As a result, bifacial panels often come with longer warranties. Bifacial solar panels might come with a higher initial price tag than their traditional counterparts. This is due to the more complex manufacturing process.
