Bifacial solar panels: a smart choice for Australian homes
Not all solar panels are created equal. Bifacial dual-glass panels generate power from both sides of the module, more output from the same roof space.
Solar is more popular and affordable than ever, but not all panels are created equal. Design, technology and performance all affect how much value a panel delivers over its lifetime.
One of the latest innovations is the all-black bifacial solar panel, a dual-glass panel built with n-type cells that generates power from both sides of the module. N-type cells use high-purity silicon and offer more power, higher efficiency and lower degradation than older cell technologies.
What are bifacial solar panels?
Bifacial panels are sleek, black-framed modules covered with tempered glass on both sides. That dual-glass construction resists dust, moisture and physical stress, improves fire resistance, and adds reliability and stability over the life of the system.
How do they work?
The front of the panel captures direct sunlight, just like a conventional panel. The back captures diffused and reflected light from the roof and surroundings, converting it into extra power, known as the bifacial gain. Depending on conditions, that gain can range from a few percent up to around 25%.
The amount generated by the rear of the panel depends on:
- the tilt angle of the panel,
- its distance from the roof surface,
- the colour and material of the roof, and
- the time of day and year.
Why they're a smart choice
- Higher output: Solahart's bifacial panels are rated at 440W and 22% efficiency, and being bifacial, they can generate even more from the same roof space, potentially reducing the number of panels needed.
- Longer warranty: the dual-glass structure protects against micro-cracks and improves fire rating, backed by a 30-year product warranty and a 30-year performance guarantee.
- More energy over time: even flush-mounted residential installs can achieve meaningful performance gains that add up across the life of the system.
For homeowners looking to maximise their solar investment, bifacial panels are a durable, future-proof option that delivers more energy, lower bills and a smaller carbon footprint. Get in touch to find out whether they're right for your roof.
