This is most often found in cheaper brands of monocrystalline and polycrystalline panels made by small relatively unknown companies.

																	Thin film solar panels often have a standardglass because they are cheap. 
																	The thicker the glass in the crystalline solar panels the more stableare they. 
																	In crystalline solar panels a 3 to 4mmthick solar glass is often used.

																	Glass besides being breakable would be very difficult for me to mount on my panel because of it s weight and fragile ness. 
																	That s not too bad let s say a new panel without plexa is 4 9a a 25 year old panel itself will degrade to about 4 a and with a 25 year old plexa will give about 3 4 a which is not so bad after 25 years. 
																	Hiku these solar panels are polycrystalline with high power output up to 405w. 
																	Diamond these panels are characterised by a heat strengthened glass which makes them weather resistant and durable. 
															
													
									
	
		
	
																	However it can also be found in well known brands in amorphous thin film solar panels that have a glass plate component. 
																	All black these panels have a black finish and are monocrystalline. 
																	Up to 90 percent of visible light transmitted the glass absorbs only ultraviolet and infrared.
