What You Should Know About
Unisolar Solar Panels

Unisolar solar panels are a little different than the other solar panel kids.

Uni-Solar Solar Panel

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?

  • Flexible

  • Light-weight

  • Easy to install

  • Durable

  • "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:
