- embodied energy of 1000 MJ/kg or 300 kWhr! [1]
- Compare to steel at 20 MJ/kg [2], and 10x 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]
