The relationship between the weight and the power of solar wafers!Often see solar wafers, some reports how many watts (power), but some also reported how many tons, I do not know the relationship between the two and how to convert
Calculation：The thickness of 180 unchanged, unchanged weight of the 156 monocrystalline silicon, conversion efficiency of up to 20% cases,Monolithic Power: 156*156*0.2/1000=4.86WThe consumption per watt of monocrystalline silicon wafers is: 27.23g/4.86W=5.6g/w
The thickness of the silicon wafer is unchanged and the weight is unchanged:156*156,8 inch polycrystalline silicon chip efficiency reached 16%, single-chip power of 3.89W.This can be pushed: the thickness of the silicon wafer is 180, the efficiency is up to 16%, and the consumption of the single silicon is 3.89w*7g/w=27.23g.When the thickness of silicon wafer is 180, and the weight of silicon wafer is unchanged, the conversion rate of polycrystalline silicon chip is up to 18%, and the chip power is 156*156*0.18/1000=4.38WThis can be pushed: the thickness of the silicon wafer is 180, the weight of the silicon wafer is unchanged, and the conversion rate of the polycrystalline silicon sheet is up to 18%, and the polysilicon consumption per watt is 27.23/4.38=6.2g
156*156,8 inch polysilicon chip Accounting: efficiency of 16%, the thickness of the silicon chip is 180, corresponding to the amount of polysilicon per watt on the map is 7G.
