What are Bifacial Solar Panels?
Bifacial solar panels are like regular solar panels but can capture sunlight from both sides. This means they can produce more energy. Normal solar panels just catch sunlight from one side. The front side of a bifacial panel captures direct sunlight, while the back side takes in the light that bounces off other things, like the ground.
Where Do They Work Best?
These panels work best over reflective surfaces like sand or snow. They might not work as well on rooftops because there’s less light bouncing back. But they’re great for places near pools, under shelters, or in gardens.
Types of Bifacial Panels:
Strong panels with glass on both sides.
Front side is glass, but the back is a clear covering. This type is usually cheaper.
Front is glass, back is solid.
Monocrystalline types of these panels are most popular because they work better with the two-sided design.
Pros and Cons of Bifacial Panels
- They produce energy from both sides, so they can make more power.
- They’re tough and last long, especially the double-glass type.
- They look nice and can raise your property’s value.
- They can save money in the long run.
- They work at many different angles and are environment-friendly.
- They’re more expensive at first.
- They might not work well if something blocks the sunlight.
- They’re heavier and can be trickier to install.
These panels can be 22-23% efficient depending on their design and material. They often perform better than regular solar panels, especially when they can move to follow the sun.
In the U.S., it usually costs between $6,000 and $12,000 for a bifacial solar panel setup. The price can change depending on the maker and design.
Comparing Bifacial vs. Regular Solar Panels:
Bifacial panels get sunlight from both sides; regular panels only from one.
Performance in Snow:
Bifacial panels can still work even if one side is covered in snow.
Bifacial panels can produce up to 30% more power.
Bifacial panels can be set up in many ways, but they’re more complicated to install and are made of more materials.
Are Bifacial Panels Worth It?
Bifacial panels can produce more power, so even if they cost more at first, they might save money over time. They’re especially good for places with lots of snow or small installation spaces.
Installing Bifacial Panels:
- Make sure nothing blocks them.
- Don’t let other parts of the system shade the panels.
- Leave some space between the panels so snow doesn’t pile up.
- Install them a bit above the ground.
- For more power, set them up over bright surfaces.
Bifacial panels are heavy but are great for special uses like RVs. Some companies make panels just for these situations.
Bifacial solar panels cost more at first, but they have many benefits. They can be especially good in places with lots of snow or small spaces. As more people use them, their prices might go down, making them a popular choice for many homes.
