Unisolar solar panels are a little different than the other solar panel kids.
In fact, they aren’t so much solar panels as thin-film solar laminates.
Unisolar is a world leader in thin-film technology and has developed a technology to reduce the materials cost in a solar cell.
Unisolar efficiency has also achieved world records for thin-film panels.
They have accomplished this through a “multi-junction” approach that lays different levels of amorphous cells on top of one another.
What are the benefits of this thin-film technology?
- Easy to install
- “Real world” efficient
Are you wondering about the difference between “thin-film” technology and a standard solar panel?
Well, here are the basics: Thin-film is cheaper but it is less efficient so you’ll need to use more space to achieve the same output as traditional solar panels.
So, you say, if thin-film is less efficient why does Uni-solar tout their “real-world” efficiency? This is because thin-film technology performs better than a solar panel in cloudy or hot conditions. Depending on your climate, this could be a big advantage.
Thin-film technology is an exciting growth area in the solar world and Uni-Solar solar panels will be at the forefront of the movement.
Here are the specs on Uni-Solar products:
