New solar panel double-sided power generation

As the name suggests, it refers to a photovoltaic cell module formed by two pieces of glass and solar cells composed of a composite layer, and the cells are connected in series and connected in parallel to the lead ends. In recent years, double sided glass solar panels are like riding on a rocket, and their popularity is soaring.

Most of the solar panels you see are mono-facial solar panels. Sunlight hits the top face of the solar panel, and it generates electricity. But those aren't the only kind of solar panel that is out there. There's another type – bifacial solar panels. With bifacial panels, an extra part of the solar panel produces electricity – the back face.

The technology behind solar panels continues to evolve and improve. Manufacturers are now able to produce bifacial panels, which feature energy-producing solar cells on both sides of the panel. With two faces capable of absorbing sunlight, bifacial solar panels can be more efficient than traditional monofacial panels – if used appropriately.

The design allows solar energy to be captured from both sides, with the back panel achieving an efficiency of 91-93% of the front side. Developed at the US Department of Energy's National Renewable Energy Laboratory (NREL), the bifacial solar cells harvest sunlight that is reflected onto the back of the cells.

And, as we'll discuss, bifacial panels are also more expensive than traditional single-face panels, which can affect the breakeven point of your investment. Bifacial solar panels can capture light energy on both sides of the panel, whereas monofacial panels (AKA traditional solar panels) only absorb sunlight on the front.

Bifacial solar panels are not suitable for rooftop installations but may work well with residential ground-mounted solar systems. The ideal use case for bifacial solar panels is in commercial and utility-scale solar installations.
