Why Are Solar Panels Black

So in order to produce solar energy black color panels are used so that more and more sunlight gets absorbed.

Why are solar panels black.

This blog post explains why some solar panels are black and some are blue and the difference between the two. They are made from a single high quality silicon crystal. The solar panels which are black in color use the monocrystalline. Because of the way light interacts with a monocrystalline silicon layer monocrystalline solar panels appear black in color.

Black solar panels are monocrystalline solar panels and are created from the highest quality silicon. Solar cells are normally placed on a white backsheet which creates a grid of white lines around them. Solar panels and installation involve high initial expenses but this cost is soon offset by savings on energy bills. Because of the way light interacts with a monocrystalline silicon layer monocrystalline solar panels appear black in color.

Black color or dark colors absorb more sunlight and light colors reflect back sunlight. The silicon used to make monocrystalline solar cells has a high level of purity. But when dark monocrystalline cells are placed on a black backsheet it is difficult to distinguish the grid from the cells and so it creates a black solar panel. In the long run solar power is economical.

The process of aligning the silicon into one crystal known as the czochralski process is energy intensive and results in some wasted silicon. Black solar panels also known as monocrystalline panels are more efficient as black is a good absorber. The ability to generate clean solar power during a blackout is an advantage of going solar. Solar can increase the value of your home.

The silicon is all oriented the same way in a monocrystalline solar cell creating one large silicon crystal. The silicon used in polycrystalline panels is made from raw silicon that has been melted and poured into molds which give their square shape. This silicon has a higher level of purity as compared to the silicon crystals used in blue polycrystalline solar panels. Black solar panels are more efficient than blue solar panels because black color can absorb more light than blue color.
