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]
Total for 1kW of PV
- 600 kWhr for 2 kg of silicon
- 3kWhr per my for glass, or
Links
- DIY Glacial Acetic Acid
- Wikipedia says 585 kWhr/m2 of PV panels? [7]
