Price of amorphous photovoltaic panels

Amorphous solar panels are the cheapest per watt ($/watt). Amorphous solar cells are more widely used in low-power electronics than solar panels. Amorphous solar panels aren't for everyone: they are much less efficient than traditional solar panels.

Amorphous solar panels are significantly less efficient than traditional solar panels. Most amorphous solar panels are only about 7 percent efficient, whereas monocrystalline and polycrystalline panels can exceed 20 percent efficiency. This means you'll need much more roof space to get the same output as traditional solar panels.

These solar panels are made from non-crystalline silicon on top of a glass, plastic, or metal substrate. Unlike other solar panels, amorphous solar panels don't use traditional cells; instead, they're constructed using a deposition process that involves forming an extremely thin silicon layer on top of a substrate.

The NATURE POWER 7-Watt Amorphous Solar Panel costs $5000 for a 2-pack. This suggests that a single panel costs approximately $2500.

Amorphous photovoltaic technology has been rendered obsolete due to severe competition from more traditional crystalline silicon cells and other thin-film solar cell technologies such as CdTe and CIGS. To make solar pv modules for devices that don't need a lot of power, such as pocket calculators, affordable amorphous silicon (ASi) was employed.

Some experts recommend installations of amorphous solar panels in places like greenhouses or windows. While amorphous solar panels may be cheaper in terms of $/watts, you'll probably save more overall with traditional solar panels because of their higher efficiency.
