Why Choose a Bifacial Solar Panel? (And Why Our 440W Full Black Panel Is a Game-Changer)
When it comes to solar power, getting the most out of every ray of sunlight is key. That's where bifacial solar panels come in — offering a smart, efficient way to boost your energy production without needing more roof space or ground area.
At GridFree, we’re excited to offer the TW Solar 440W Full Black Bifacial Solar Panel, designed to give you more power, better durability, and a sleek, modern look for your solar setup.
Here’s why bifacial panels are a great choice, explained in simple terms:
What is a Bifacial Solar Panel?
Most standard solar panels only collect sunlight from one side — the front.
Bifacial panels are special because they collect sunlight from both the front and the back.
This means they can produce more electricity using the same space!
The front of the panel captures direct sunlight, just like a normal panel.
The back side picks up reflected sunlight from the ground, nearby surfaces, or even light bouncing off water or concrete.
It’s like having a bonus solar panel built into the back!
The Main Advantages of Using Bifacial Solar Panels
1. More Power Without Needing More Panels
Because bifacial panels generate energy from both sides, you can get up to 10–30% more power compared to regular panels.
This is especially useful if you have limited roof space or want to maximise your system’s output.
2. Better Performance in Low Light
Bifacial panels are more efficient even on cloudy days or when the sunlight isn’t perfect.
They make the most of every bit of available light, meaning more consistent energy production across the year.
3. Stronger and Longer-Lasting
Our 440W Full Black Bifacial Panel is made with a dual-glass design.
Instead of a plastic back sheet like normal panels, it has a second layer of strong glass.
This makes it more resistant to water, humidity, heat, and mechanical damage, giving it a longer life — and better performance in tough New Zealand conditions.
4. Sleek, Full Black Look
Not only does the TW Solar 440W panel perform well, but it also looks great.
The full black finish gives your solar array a modern, clean appearance that blends nicely with most roofs and homes.
5. Amazing Warranties for Peace of Mind
This panel is backed by a 25-year product warranty and a 30-year performance warranty.
That’s longer than most standard panels — meaning your investment is protected for decades.
