For China-based firms, the percentage of shares short is not available because the companies are also listed on other exchanges.

First Solar Inc. (NASDAQ: FSLR) short interest fell by 10.8% to 16.43 million shares, which represents 27.3% of the company’s float.

Suntech’s bankruptcy filing in the second half of March cooled the ardor of short sellers for the Chinese solar stocks. Instead of piling in, short interest either declined or rose modestly in all the Chinese stocks.
The next report on short interest should reverse what we have seen today. First Solar gave the entire sector a lift yesterday when it boosted its outlook for 2013 and share prices rose dramatically. Anyone caught short yesterday in any solar stock very likely got a bad sunburn. But nothing much has really changed in the sector: module prices are a little more stable but remain low, and government support for solar installations is not growing. Look for the shorts to wade back in.
