The document reports weekly spot prices for solar PV components like polysilicon, wafers, cells and modules. It shows that average polysilicon and module prices decreased last week, while wafer and cell prices increased slightly. The concluding paragraph notes that without strong demand, solar component price increases are not sustainable, and module price increases would need to be seen for component prices to rise more optimistically.

Solar panel prices showed solar demand not really strong.

2. In the past, all solar PV component prices normally showed a consistent uptrend ate the same
time. In the past two months, solar wafers seemed to have some regional shortage. However,
without strong solar system demand support, solar component prices will not be sustainable. Once
if solar panel prices show an uptrend, solar PV component prices will be more optimistic..
Average poly-silicon price was down 0.89% to the price of US$ 55.5 per Kg as last week.
Average156mm sq poly wafer price went up 0.3% to the price of US $3.39. Average solar cell
price increased 0.78% to the price of US $1.29 per watt. Average solar module price went down
0.58% to the price of US $1.79 per watt.
