Back of a Speed Solar Philadelphia Bifacial Solar Panel

Bifacial is Better

Bifacial solar panels are the next step in solar energy because they offer increased power and resilience at a competitive price:

  • Produces up to 25% more power than monofacial modules
  • Excellent low light performance especially on cloudy or overcast days
  • Particularly effective in ground mount or flat roof conditions

We’re so confident about our product performance, we’re posting the test results so you can see the difference for yourself.

What Makes Bifacial Solar Panels the Better Choice

It all comes down to the sun. All other things being equal, size of the roof, location of the site, impact of the weather on the array, bifacial solar panels take in and use more light than the same number of monofacial panels.

Bifacial solar panels (modules) have solar cells on both sides of the unit, with glass on the front and a clear fluoropolymer sheet on the back, allowing them to produce up to 25% more energy than the typical monofacial solar panel widely used today.

Bifacial modules can be used with standard racking and inverters for any type of solar array. They perform excellently in low light situations, are PID resistant, CEC certified and come with a 25-year warranty.

Best of all, bifacial modules are comparably priced to monofacial modules, with discounts available for volume orders.
