Bifacial solar modules - that can generate electricity using both sides of the panel - aren't a new invention, but developments in technology have significantly increased their efficiency and created the potential for them to be a big player in the Solar PV market.


Studies show that they can produce additional power between 10-20% over monofacial panels. And if conditions are optimized, that additional power can be as high as 30-40%

The solar fence has an output of 400 W per fence section and relies on its vertical mounting technology for bifacial photovoltaic panels.


One big advantage of installing bifacials vertically, as in the solar fence pictured, is that it will experience a double peak each day as the sun makes its way around (we know that technically it's the Earth making its way around, please don't write in...)

During each peak, the reflection of sunlight on the other side of the solar panels will also contribute to energy production.

The vertical arrangement also means that any sand, dust, or even snow, blown over in weather events won’t sit on the panels and inhibit their energy production.


The example above is one of several variants of the bifacial solar fence available for different applications in homes, businesses or agriculture and can be offered to homeowners and enterprises whose roofs aren't suitable for photovoltaic systems.

However, this doesn't mean they can't be used effectively on your roof, and they are also ideal for pergolas, awnings and car ports etc. Aesthetic and functional!  





The Techy Bit


It's our business to know all the technical details of products we're working with, and we do secretly enjoy delving into some of the finer points.

So how exactly does a bifacial solar panel work?

As the name would imply, bifacials are equipped with solar cells on both the top and the rear of the panel. The top faces the sun in order to capture the sun's rays directly, as we are used to in a conventional solar panel array.


The bottom solar cells absorb light that's reflected off the ground or the surface underneath. This light is called 'Albedo Light'.
White or light colours reflect better than dark colours and so painting a white or silver surface on a roof or concrete driveway under the panels will have a positive effect on their energy production.

Studies show that a white surface reflects more than 80% of albedo light. By comparison, grass reflects around a mere 23%.

The installation and mounting of your bifacial panels is then all about minimizing shading, using only very narrow support rails and corner-only vertical supports, meaning more solar power for you!

Because sunlight bounces off of all objects reflectively at many different angles, bifacial solar panels are better able to capture more of it.
They are even productive on cloudy days when monofacial solar cells are at more of a disadvantage.
