Don t underestimate the value of your north facing roof area poly and mono solar panels are the best choice even just on that point alone.
Compare amorphous crystalline solar panels.
One layer of silicon on an amorphous solar panel can be as thin as 1 micrometer which is much thinner than a human hair.
Adding to the overall cost of the system.
They can also withstand the summer heat where mono or polycrystalline panels lose efficiency in the same ambient temperatures.
Crystalline panels do not perform as well in partial shading compared to amorphous cells and they do gradually lose a small percentage of output as the temperature rises above 25 c.
Panels that are made from monocrystalline solar cells are basically fashioned from silicon ingots that have a distinct tube like shape.
Some amorphous thin film panels actually need more mounting rails and take longer to install.
Amorphous is inherently less efficient than crystalline only being around 7 10 efficient at light conversion compared to a crystalline panel of the same size which has typically between 12 15 efficiency.
Like conventional solar panels amorphous solar panels are made from silicon but they are constructed in a different way.
Crystalline panels need to be as perpendicular to the sun as possible to achieve the best performance.
