They are solid black without the normal silicon cell outlines you see on the face of a crystalline solar panel.
Amorphous crystalline solar panels.
Amorphous silicon is the non crystalline form of silicon used for solar cells and thin film transistors in lcds.

They can also withstand the summer heat where mono or polycrystalline panels lose efficiency in the same ambient temperatures.
Amorphous panels can be made for much less than crystalline panels and it seems the industry is set up for self sabotage because they seem to want to do whatever it takes to make sure these amorphous panels stay high at ridiculous prices and or are impossible to get.
Other issue is that amorphous panels are about 1 2 the efficiency of crystalline panels so you need 2x the square footage and racking wiring etc for the same amount of power.
Thin film solar panels are completely different from monocrystalline and polycrystalline solar panels.
If the life of a solar panelis important to you then this is a factor to consider.
Amorphous silicon cells generally feature low efficiency but are one of the most environmentally friendly photovoltaic technologies since they do not use any toxic heavy metals such as cadmium or.
Amorphous thin film is yet to prove itself in harsh conditions over a long period of time.
Instead of being constructed from solid silicon wafers like mono or poly crystalline solar panels amorphous panels are made by depositing non crystalline silicon on a substrate like glass plastic or metal.
In many grid connect packages where thin film is utilized the panels have a cover of plate glass.
Amorphous solar panels are manufactured using a thin film deposition process laid onto glass wherein the prescribed voltage and current are created as part of the actual manufacturing process.
One layer of silicon on an amorphous solar panel can be as thin as 1 micrometer which is much thinner than a human hair.

There are essentially two main types of solar panels used in consumer solar products amorphous and crystalline.
Each type uses a different manufacturing process and has distinctive attributes which impact cost and performance.

Used as semiconductor material for a si solar cells or thin film silicon solar cells it is deposited in thin films onto a variety of flexible substrates such as glass metal and plastic.
Amorphous panels are also lighter in weight and more portable than monocrystalline or polycrystalline panels producing the same amount of energy.
Usually thin film solar panels are lightweight and flexible making them easy to install.
