PV Panel Embodied Energy

embodied energy of 1000 MJ/kg or 300 kWhr! [1]
Compare to steel at 20 MJ/kg [2], and 200MJ/kg more than this for aluminum [3]
How many grams of silicon are needed for 1kW of PV panels? 2 kg [4], based on 2g/W.
5% of weight of PV is silicon [5]. 76% is glass, 10% is aluminum, and 10% is EVA.
Embodied energy of EVA is about 80 mega joules per kilogram [6]
