The term black solar panels almost always refers to monocrystalline panels that look black to the eye.
Black crystal solar panels.
If you see a solar panel with black cells it s most likely a monocrystalline panel.
Black solar panels monocrystalline are often more efficient as black surfaces more naturally absorb light.
Polycrystalline solar panels are also made from silicon.
A black backsheet is a bad choice from the point of view of efficiency because the hotter solar panels get the worse they perform and in sunlight black gets hotter than white.
The vast majority of modern solar photovoltaic panels are made using silicon a non metallic element that is used in most modern electronics.
These cells appear black because of how light interacts with the pure silicon crystal.
In addition polycrystalline solar panels tend to have a blue hue instead of the black hue of monocrystalline panels.
Black or monocrystalline solar panels are made from a single crystal of silicon.
Lastly mono panels have a uniform black look because the cells are made from a single piece of silicon.
The solar cells within monocrystalline panels are a single flat black color which makes them popular among homeowners.
However this process is resource intensive in energy consumption and wasted silicon.

Polycrystalline solar cells are blended together from multiple pieces of silicon.
However instead of using a single crystal of silicon manufacturers melt many fragments of silicon together to form the wafers for the panel.
I personally think these look better than poly panels but obviously that is just a matter of preference.
So the gaps between solar cells on a panel with a black backsheet will absorb heat instead of reflecting it.
So if sanctity and purity are important to you it s black solar panels all the way to the altar of your rooftop.
You can identify a monocrystalline panel by the shape of the silicon wafers which are shaped like squares with the corners cut off.
While the solar cells themselves are black monocrystalline solar panels have a variety of colors for their back sheets and frames.
Black solar panels are made from monocrystalline silicon that achieves a higher standard of purity.
This silicon has a higher level of purity as compared to the silicon crystals used in blue polycrystalline solar panels.
