What is the difference between Amorphous , Multi-Crystalline and Mono-Crystalline solar cells and panels .

Amorphous are cheaper to produce as they are a very thin film poured over a glass plate
and allowed to cool - They have an efficiency rating of around 6 to 6.5% on average . Amorphous cells
operate in most light sources but are low-powered - consequently the uses are small appliances where a
low current is required - eg - Solar-powered calculators. 2 square metres of panel could produce between
120 and 125 watts of electrical energy.

Multi-crystalline are made up from slices of silicon crystal fused together and then
sliced into cells - These are more expensive to produce than Amorphous but have a higher efficiency rate
of around 14-16% - 1 Square metre of panel could produce between 100 and 130 watts of electrical power.

Mono-crystalline cells are sliced from a single silicon rod are the most expensive
to produce - However they are more efficient than the other 2 having an efficiency rating of 15 to 18%.
1 square metre of panel could produce between 130 and 160 watts of electrical energy .

Each of the above suffers from output loss once the panels reach 50 degrees celsius or
above - Losses from 10 - 15% should be expected and factored into any calculations for systems where
ambient temperatures will consistently be above 40 degrees celsius.
